Checking the video card
Error 43 video card must be previously identified. To do this, you need to check if the computer correctly recognizes the device.
You can perform diagnostics like this:
- Click on Start and right-click on “Computer”, then select “Properties”;
- Now in the left menu click on “Device Manager”;
- It is necessary to expand the list “Video adapters”;
- Check that the video card is working normally. To do this, you need to Pay attention to the icon, there should NOT be exclamation marks next to it. Also, the device may be located in another section “Unknown devices”. When you click RMB and “Properties” you will see an error with code 43.
This error reports that the device has encountered a problem or a failure is provoked in it and therefore the device is stopped. If an exclamation mark is found nearby on an orange background, then most likely the problem is in the system part. When there is such a sign, the malfunction is on the hardware side or lies in the RAM.
Error code 43. how to fix it by increasing the amount of memory
As previously mentioned by Nvidia, error code 43 can be triggered by a conflict between the RAM and the video card. There is a fairly effective means to normalize the operation of devices. to increase the amount of allocated memory, this can be done as follows:
- Click on Start and then “Control Panel”;
- Find the category “System and Security” and open it;
- Then click on the “Administration” item;
- Select “System Configuration” from the list of administrative elements;
- You need to go to the “Download” tab;
- Now select the active operating system and call it the “Advanced Options” button;
- Select the “Maximum memory” section, check the box next to it and set the value, for example, 8 GB;
- Restart the system.
Most of these methods are enough to fix the problem with error 43, but there are several additional ways to deal with the malfunction.
Code 43 video card error. initial steps
If error 43 of the nvidia video card pops up, you need to first check the serviceability at the most primitive level. Despite the banality of actions, they are able to restore work quite often.
The first option is to simply restart the system. It is likely that the error is caused by a one-time crash and after restarting Windows, the problem will resolve itself. This manipulation must be performed immediately after the problem appears.
Next, it is worth checking the health of the video card contacts at the physical level, this is important for a stationary computer to a greater extent.
- It is necessary to twist the cover from the system unit;
- Unscrew the fasteners on the video card, then remove the adapter itself;
- Next, he will clean the contacts from dust and debris with a brush;
- Reconnect the device and start the system;
- In the course of work, it is worth checking that the cooler is working properly.
Dust can cause various problems with your computer, so even error 43 can occur due to this.
Sometimes the problem is provoked by a failure in the RAM, that is, the breakdown of some kind of bar. To do this, you need to open the system unit and remove all the strips except one, the volume of which does not exceed 2 GB. If an error does not occur, you can add one more bar and so on until the culprit is identified. The optimal amount of memory so that an error does NOT appear is considered 4 GB.
You can also check the system using the chkdsk / f command, which you need to enter into the console (Win R and cmd).
Eliminate error code 43 using registry settings
All the need to understand how to fix error 43 manually, as there are special applications that independently perform the analysis of the registry and correct the found inconsistencies. One of the best utilities in this direction is CCleaner, while it is quite widespread, so let’s take it as an example.
- Download the app https://ccleaner.Org.ua/download/;
- Start the program and go to the “Registry” tab in the main window;
- A list of the problems you are looking for will appear on the left, it is better to select a selection next to all the items and click “Search for problems”
- After the end of the analysis, you need to click on “Fix”.
The procedure can be repeated several times, since the program does not always immediately identify all problems or it was not able to eliminate the malfunction during the last cycle. To check if the method helped, you need to restart your computer.
How to fix error code 43 on your graphics card?
Error code 43 indicates certain system malfunctions that are related to the video card. The problem lies in the incompatibility of any drivers, a conflict between RAM and a video card. Users who have eliminated the error note the possibility of solving it by restoring the registry, respectively, the problems may be with incorrect system behavior.
Other solutions for error 43
It is likely that the driver was exposed to some kind of unwanted influences, this can be caused by the fact that the driver is outdated or, on the contrary, due to a problem with the new version. In any case, installing the software for the video card will help solve the problem. This requires:
- Go to the video card manufacturer’s website (NVidia or Radeon)
- Select the item “Support”, “Drivers” or similar;
- Specify the parameters of the video card installed in the computer in the filter;
- The search will reveal a suitable driver version, and you just have to download it;
- Next, you need to delete the previous one, the broken version will go to the “Device Manager” (as described earlier), find the video adapter, right-click and select “Delete”;
- Run the downloaded file with the new driver and wait for the installation to complete.
It happens that the problem is not at all in the hardware, but simply the video card gets very hot. The reason may be an inoperative cooler, broken fan blades, or an outdated video card. It often happens that for years no one has been servicing the system unit, and from this comes the overheating of the device.
To fix the problem, you need to remove the cooler or radiator and change the thermal paste. It also happens that the cooler periodically jams and it does not start, then overheating quickly occurs and the system turns off.

Problems with the laptop video card and their solution
One of the key components that determines the price and configuration of a laptop is the graphics card. The video card processes video content, the quality of graphics in games depends on it.
There are two types of video adapters for laptops. built-in and discrete. The built-in video adapter is part of the motherboard and uses part of the RAM as video memory. Such devices do not cope well with games and complex graphics tasks (for example, video processing or image rendering) and they are mainly used in cheap laptops due to their low cost.
A discrete graphics card is a separate device that has its own slot in the motherboard (for laptops. MXM). They have their own video memory and better performance. These cards are used in powerful gaming laptops and budget multimedia devices.
In this article we will describe solutions to most problems with a video card, some of which can be solved at home.
As mentioned above, the video card displays the image on the screen. In the case of its Incorrect work, an image with defects, stripes or not at all is displayed on the screen.
The most common problem, especially in Windows XP, is installing video drivers on a laptop. Various assemblies of the system contain their own drivers, which do not always work correctly. They usually contain desktop versions of drivers that do not work for laptops. Ideally, if the system does not have any video driver, it should be installed from the disk, which came with the laptop or from the official website of the video card manufacturer. If the driver is already installed (with assembly or just incorrect installation), then you should remove the incorrect driver and install a working.
The second common problem is installing drivers and switching modes in laptops with two video cards. integrated and discrete. In a system where one of the video cards is ATI, switching is carried out through the Catalyst Control Center.
The Nvidia Switchable Graphics switch is more automated. For each application, you can assign your own video card, and it will turn itself on when you start this application. But drivers are much more difficult to find.
It should be noted that you can programmatically switch drivers only in Windows 7 / Vista, in XP there is no such possibility and the video card can be switched only in the BIOS.
When the driver is not working, some applications DO NOT start, it is impossible to change the resolution to a higher one and some more problems arise with the launch of multimedia.
In addition to problems with the drivers, there are a number of problems that can be identified by external signs:
In games or applications requiring a video card, various distortions and artifacts appear at startup. In some cases, the laptop may restart and shut down. In this case, the reason is usually overheating of the laptop and to eliminate it, you need to clean or change the cooling system. Dust that accumulates inside the laptop can cause it to overheat. Cleaning should not be carried out at home, in order to avoid damage to internal components, it is better to immediately give it to the center. Sometimes it is worth replacing coolers with more powerful ones.
During operation, streaks or artifacts may appear on the screen, sometimes the screen may simply remain dark. The malfunction can be both in the video card and in the matrix. In any case, whether the reason lies in the video card or in the matrix, the laptop should be carried to the service center. Repair of the matrix should also be carried out in the service center so as not to damage it (the matrix is an expensive part of the laptop).
If the laptop does not turn on, then either a video card or an inoperative component of the motherboard (most often the south bridge) may be a prerequisite. At home, it is difficult to check this, so a preliminary diagnosis should be carried out at a service center to determine the type of breakdown.
There are a number of different malfunctions associated with the incorrect operation of the video card, but they should not be considered here. For more information about the types of video card breakdowns and methods of eliminating them in the service center, read our publications.
In conclusion, we can say that in any case, in case of internal damage and malfunctions, it is not worth disassembling and independently carries out repair work. Repair of laptops is a very delicate and delicate work that requires Special knowledge, qualified personnel and equipment. At home, you will only aggravate the breakdown and spend extra money to eliminate the consequences of your intervention. Therefore, it is better to immediately send the laptop for diagnostics and subsequent repair or replacement to a service center. This will allow you to troubleshoot faults in the shortest possible time and at minimal cost in order to reap all the benefits that a laptop provides.
Our service center carries out high-quality repair of a video card for any laptop using its own spare parts from trusted suppliers and naturally provides guarantees for video chips and work.

Graphics card problems
Diagnosing problems with a video card (provided that the problem really is in it) is usually much easier and faster than the second component. First of all, because an indicator of its work is also the presence of an image on the monitor. It. It is logical: if the video card is working. We see the image if the video card is not working. Not visible.
This fact is verified quite simply. You just need to substitute a known good card instead of the previous one. In the case of integrated video, this method usually also works.
Graphics card problems can start with the question: Is my graphics card working properly? Such a question would be very pertinent, Considering the fact that cases of unstable functioning of video cards, although not centuries often, are still encountered.
Here’s a real example. I started having problems with my Nvidia graphics card. It was a good device (in its class and at one time). Model 7600 GT, 256 megabytes of video memory. Yes, there she is! 🙂
Video memory chips (64 MB each) are circled in red in the photo.
This card worked properly for me for several years, but one hot summer day the computer froze and after a forced restart I realized that there were problems with the video card. On the face. Although, at first it seemed to me that it was corny “flew off” video driver (the image on the monitor had a color palette of 16 colors and a resolution. Less than 640 by 480 pixels).
When trying to reinstall the driver, I made sure that I really have. Graphics card problems. System “hung up” tightly.
Having opened the case, I visually examined the device. In appearance. Everything is fine: the fan above the radiator is spinning properly. But, having touched the video memory chips, I understood everything. They were very hot! And then I realized that it was not in vain that on expensive models of video cards the video memory is also covered by the radiator, but, alas. It was too late. The memory of the video card, which had been in constant overheating mode for a long time, finally could not stand it.
What is typical in this problem with a video card: it continues to work now, but the picture on the monitor is like this:
You can rate everything “wealth” gamut of sixteen colors and a series of vertical stripes across the entire monitor 🙂 Is the video card working in this case? Formally. Yes, but, nothing more.
And this is how my desktop looks like 🙂
With this example, I wanted to show you that problems with a video card can be considered Not only in the plane: it shows. Does not show, but even in such uncharacteristic states of malfunction.
I would also like to draw your attention to the fact that problems with a video card can be caused by a software component: an unsuitable driver installed for it, or “raw” (unstable) version of this driver itself. Such cases were encountered in the practice of our IT department.
As a rule, after installing such an inappropriate driver and rebooting the system, we can see a pop-up window with a warning about an interrupt conflict, and in the worst case. Spontaneous shutdown of the display some time after loading the operating system. Typically, when replacing the graphics adapter with a known good one. Video card problems stop.
It is in such a situation that you should use one of the secure boot options for Windows, which Microsoft has so kindly provided us with. 🙂
This is a secure boot of the operating system with VGA mode enabled. In order to get into the window for selecting boot modes in safe mode, we need to press the “F8” function key during the initial boot of the system. If we did everything right. The following window will appear:
In it, we will need to use the arrows on the keyboard to select the item “Enable VGA mode” (in the photo above it is marked in red) and press “Enter”.
The operating system will boot using the standard video driver, at a resolution of 640 by 480 dpi and using a color palette of only 16 colors. Exactly what we need will happen (the unsuccessful driver will be simply ignored) and already in this working configuration we can remove it and install another one that works stably.
Based on personal experience, I can also recommend: Paying increased attention to the cooling of the video card! Many devices with a basic cooling system (installed by default) may not initially operate at optimal temperatures. If we add here other external factors: hot summer, lack of normal ventilation in the system unit itself, installing the system unit in an unsuitable place for it, etc., then we can easily get the device overheating and, as a result. Graphics card problems.
Many people are already aware of this problem. Therefore, they are trying (as they can) to solve it themselves. Here, for example, is a photo of one of these “decisions” 🙂
If you look closely, you can see that the fan is tied to the textolite plate of the card with threads!
Here’s another perspective, closer:
over, the fan, as you can see, is unscrewed from some kind of computer power supply.
This copy came to us recently for prophylaxis in a completely inoperative state. The customer asked to find out if the video card is working? Found out. Works 🙂
Personally, I now pay increased attention to cooling the video card and the entire system unit as a whole. Count how many fans are inside my home computer? 🙂
In conclusion, I would like to say a few words about the problems with the video card in laptops. Here, in fact, everything is the same except for the fact that, due to its design features, the laptop requires even more attention from the user in matters related to the prevention of its overheating and proper operation.
Very often, problems with a video card in various laptop models are associated precisely with their prolonged overheating. Graphically, the chip, along with the central processor, are the main heat generators in the case and the heat removal system, especially if it is clogged with dust, cannot always effectively cope with its task.
Pay attention to the photo below:
See those vertical white streaks across the entire screen? Video card problems can manifest themselves in different ways. If we consider the process itself, then when overheating occurs a thermal breakdown of “p-n” junctions in the silicon crystal, as a result of which the microcircuit begins to gradually fail. This usually does NOT happen right away. Notebook “freezes”, various (vertical or horizontal) stripes, color dots appear on the screen, the image may split into several parts, be duplicated.
After a while, the chip is completely out of order and the image is no longer displayed on the screen.
So always keep an eye on the temperature inside your computer case. In general, the temperature of a working processor should be in the range from 30 to 60 degrees Celsius for the chipset. From 25 to 50 degrees, and video cards from 40 to 70 (under load). For a hard disk, temperatures above 55 degrees Celsius are considered undesirable.
A little more about overheating. Always remember the following: most modern devices (processor, same video card) can operate in different modes. First of all, I mean different modes of energy saving and reduced performance in abnormal situations. One of these “situations” overheating may well become. In this case, the device, if it can, will go into one of the emergency or energy-saving modes.
Why might this matter? I will tell you one story: in a familiar began “to brake” a computer. And it was during the games. And this is not immediately, but after some time spent for “heavy” the game (the picture froze, there was a general inhibition of the game process), in short. DO NOT Feng Shui! 🙂
We opened the computer case with him and began to examine it. It quickly became clear that the entire radiator, along with the video card fan, was clogged with dust. And so much so that the fan stopped! Having received a good load after launching a resource-intensive game, the video card quickly heated up and (since the cooling system did not work) went into a reduced performance mode in order to protect itself from overheating. I cleaned up all this mess and properly lubricated the fan, we started the PC again. Now everything was fine when launching games!
Also remember that not only video cards can face similar problems. Overheating of the processor is also a very NOT a pleasant thing and should always be monitored.

Windows installation problems
Question: how to install on a Windows laptop?
Question: I want to install two Windows on a laptop with a choice of which one to boot at startup. It is possible?
Question: when installing Windows on a laptop, it freezes or issues “blue screen”. What to do?
Answer: first of all, it is worth checking the memory and hard drive according to this instruction. Quick diagnostics of laptop malfunctions. If the memory and hard drive are in order, then you need to check if the laptop is overheating and take measures to cool it. details here: Laptop cooling.
Question: When installing Windows XP, the installer does not see any hard drives. What is the reason?
Answer: you need to integrate SATA drivers according to this instruction: Normal Windows XP installation.
Question: during the installation of Windows XP from a USB flash drive, I get an error with hal.Dll. How to fix it?
Answer: you need to edit the boot.Ini file as described in this article: Installing Windows XP from a USB flash drive or memory card.
Question: When installing Windows Vista / 7, the system asks for a driver for the DVD drive. Where to get the driver?
Answer: The driver is not really needed. You need to update the BIOS and try another assembly of Windows (the original is highly desirable).
Question: I DO NOT start installation from disk. How to install Windows?
Answer: first of all, it is worth checking whether it is worth booting from disk in the BIOS. If it is, but the disk still does NOT load, then you need to check if this disk is loaded on the second computers. If it doesn’t load, then you should look for another distribution. If it boots, then we try to burn the distribution from Windows to another disk.
Question: I had Windows XP / VIsta / 7 preinstalled on my laptop, but I deleted it along with the hidden recovery partitions. Recovery discs are available. Can I get a licensed system somehow?
Answer: you can. If the laptop came with the original Windows, then on the bottom of the laptop there should be a piece of paper with the specified Windows version and serial number. We take out the disk with Windows and enter that serial number during installation. After installation, you will need to install drivers and programs, as well as activate. Windows in this case will be original.
Question: I heard that it is possible to restore the system with the programs and drivers as at the time of purchase? What are the hidden partitions on my hard drive with a volume of several gigabytes?
Answer: At the moment, laptop manufacturers are less likely to complete their products with system recovery discs. The user is invited to write them down manually using a special utility that comes with the kit. To restore the system, you just need to boot from those disks, and then follow the instructions on the screen. Often, with such a recovery, the entire contents of the C: \ drive or the entire hard drive is erased. It is worth considering.
In addition to recovering from disks, you can also recover the system from hidden partitions, which are recorded by the manufacturer on the laptop hard drive. To start this recovery, you need to press certain key combinations at the beginning of the laptop boot, when the BIOS boots. For Acer laptops, this is AltF10, ASUS. F9, Dell. Ctrlf11, Fujitsu Siemens. F8, HP. F11, MSI. F11, Packard Bell. F10, Rover. Alt, Sony. F10, Toshiba. F8. As in the case of recovering from disks, the contents of the C: \ drive or the entire hard drive will be erased (except for hidden partitions, of course).
Recovery requires original MBR (boot record) and hidden partitions. The structure of the hard drive partitions is also important (the number and type of partitions). If you accidentally deleted hidden partitions, there is no need to despair. You can always install Windows from scratch by entering the serial number on a piece of paper on the bottom of the laptop. It is desirable to use original Windows assemblies. Detailed installation instructions are available on this website. You will also need to install drivers and programs. This issue is discussed in this forum thread: Windows Automatic Recovery Systems.
Solving laptop problems
Question: my laptop began to slow down in games, suspension or just turn off. What to do?
Answer: first you need to check if the laptop is overheating according to this instruction: Cooling the laptop.

Answer: Answers to these questions should be found in this forum thread: Upgrade. Discussion of ways to upgrade a laptop.
Question: I spilled tea / coffee / wine / water / other liquids on the keyboard. What to do?
Answer: First of all, you need to disconnect the laptop from the mains and remove the battery to avoid electrochemical corrosion. Next, you should turn the laptop over so that the liquid misses the motherboard. If certain keys stick or do not work on the keyboard, then they must be disassembled and wiped with clean water. In no case should you use solvents or other household chemicals. This could damage the keyboard. Often a new keyboard costs around 50-150.

Question: I can’t install Bluetooth drivers. What to do?
Answer: first you need to make sure that the laptop has a Bluetooth adapter. The presence of a button / toggle lever does NOT guarantee the presence of a Bluetooth adapter in the laptop.
Next, you should turn on the adapter and install the driver itself. Usually they are in the folder with the downloaded program. And after installing the driver, you can install the program itself via setup.Exe. If you start installing the program right away, a message may appear stating that the driver was not found.
Question: how to install drivers for the fingerprint scanner?
Answer: Installing the driver for the fingerprint reader is the same as installing the driver for Bluetooth. First, the driver itself is installed on the scanner, and then the program for working with it.
Question: I have additional buttons on my laptop. Why They Don’t Work?
Answer: additional utilities are often required for additional buttons to work. They are specific to each laptop manufacturer. You can find them on the websites of laptop manufacturers. This issue is discussed in this forum thread: Solving problems with the keyboard, touchpad and additional buttons on a laptop.
Question: The touch buttons and scrollbars on the touchpad do not work for me. How to fix?
Answer: you need to install drivers on the touchpad. Often this is Synaptics, less often ALPS and ElanTech.
Question: I cannot install the driver for sound, Wi-Fi. What to do?
Answer: You must try a different driver version first. If it does not help, then change the Windows assembly to the original one. Such problems often occur on Windows builds. This issue is discussed in this forum thread: Solving problems with the keyboard, touchpad and additional buttons on a laptop.
Question: My webcam does not work. How to fix?
Answer: first of all, you should find out from this instruction Search and install drivers on Windows which camera is installed.

Next, you need to install the driver itself, and then the program for working with the Web-camera. If you have any difficulties, then we turn to this forum topic: Solving problems with finding and installing drivers.
This article provides solutions to common laptop problems in the format “question answer”. Over time, this list will expand.
Have a problem with your laptop? Don’t know what to do? Then this material is for you. The solution to the problem should start from here. Here are the solutions to common laptop problems.
Problems turning the laptop on and off
Question: my laptop won’t turn on. When you press the button, all the lights come on and after a couple of seconds the laptop turns off. What to do?
Answer: often these kinds of problems are caused by the failure of the south or north bridge (these are such large microcircuits on the laptop motherboard) or unsuccessful BIOS firmware.
Microcircuits can fail due to overheating, due to static electricity, due to the fact that faulty equipment was connected to USB or another port. Often, repairs boil down to replacing the laptop motherboard or re-soldering the microcircuit. This is done by service centers. Replacing the motherboard can cost from 100 to 300, soldering is 50-200 cheaper. It is almost impossible to solder at home.
In case of unsuccessful flashing of the laptop BIOS, you can try to restore the BIOS. How to do this is roughly described in this forum thread: BIOS Recovery procedures / Translating BIOS Recovery procedures. There is no guarantee that everything will work out, but it’s worth a try. In extreme cases, you can take the laptop to a service center, where the BIOS will be flashed on the programmer.
Question: My laptop screen won’t turn on. When you turn on the laptop, all the lights come on, you can hear how Windows boots, but there are images on the monitor at all. What to do?
Answer: a prerequisite for this behavior of a laptop can be both a malfunction of the matrix and the video card. The exact cause can be determined using a flashlight or lamp, as well as an external monitor. If you can see something there under intense ambient lighting of the laptop matrix, then the problem is in the backlight. Either the backlight itself, or the inverter ( “Power Supply” lamps). Replacement can be done at the service center. Depending on the greed of the service center, a replacement can cost from 50 to 150. Also, the fault may be a matrix loop. Contact was simply broken. If nothing is visible on the laptop monitor, then you should connect an external monitor. If there is an image on the external monitor, then the problem is in the matrix itself or in the matrix cable. If there are images on the external monitor, then the video card is out of order. Replacement costs from 100 to 300 You need to contact the service center.
Question: my laptop turns on, but the screen has multi-colored squares / stripes / uniform illumination. How to fix?
Answer: The simplest diagnostic method is to connect an external monitor to the laptop. If there are the same image defects, then the video card is to blame. If everything is normal on the external monitor, then the problem is either in the matrix itself, or in the matrix cable.
If the problem is with the monitor or the cable, then you should try to first pull out and insert the ends of the cable into the connectors and check the places of the adhesions / twists. A sign of loop problems is also a change in noise on the screen when you change the angle of the cover. Interference usually takes the form of stripes or uniform highlights. If after THESE manipulations the image is still covered with stripes, then the matrix itself is out of order. You can replace it at the service center. Costs around 200-400.
If the image on the monitor is covered with multi-colored cubes, doubles / quadruples, defects begin after installing the video driver, then the problem is with the video card. You can replace it at the service center. Problems with the video card are discussed in this forum thread: Solving problems with the laptop video card.
Question: my laptop freezes when turned on. How to fix?
Answer: the problem can be either overheating or in programs / drivers with errors.
First, you should try to go through Safe Mode. To do this, at boot time, press the F8 button and select the Corresponding item. When the system boots up, use the CCleaner utility to clean startup and remove the faulty program. How to work with this utility is described here: Cleaning Windows from garbage using CCleaner. If that doesn’t work, then the laptop is probably overheating. How to solve this problem is described here: Cooling the laptop. Laptop cooling issues are discussed in this forum thread: Discussion of laptop cooling methods. It is also worth checking the hard drive and memory of the laptop according to this instruction: Quick diagnostics of laptop malfunctions.
Freezes when loading BIOS are often associated with poor contact between the hard drive and memory, as well as the presence of unnecessary devices in the laptop ports. To solve the problem, you need to pull the hard drive, drive and RAM a couple of times and insert it into the laptop, and also check for errors as described in the article at the link above. All external devices should be disabled.
Question: I DO NOT boot Windows. What to do?
Answer: how to restore Windows is described in detail in this material: Windows Restore. If you urgently need data on a laptop, then use this instruction: Quick diagnostics of laptop malfunctions. If you have a problem with booting Windows, then you should seek help in this forum thread: Troubleshooting Boot Problems Configuring Windows.
Question: my laptop won’t boot. PXE error appears when loading BIOS. How to solve a problem?
Answer: you should go into the laptop BIOS and set the hard drive to the first place in the boot list.
Question: When I boot, my laptop asks for a password to start or to the hard drive. How to recognize him?
Answer: if you have a BIOS from Phoenix, then first you need to download special utilities (download / download), then copy the downloaded archive to the C: \ drive, unpack it and run the Command Timeline as Administrator.
On that line, enter the command C: \ password \ BIOS_PW.EXE [your BIOS error code] 0 or C: \ password \ HDD_PW.EXE [your HDD error code] 0 To find out the error code, you need to enter the wrong password several times. As a result, the system will display approximately the following message: System Disabled , where 12345. Error code. Press Enter, and then 2 or 3 (passwords will be generated in upper and lower case, respectively). The program will generate codes for you, which are worth entering into a laptop. After a few attempts, the password will work.
If you have a 64-bit system, then these utility will have to be run through DOSBox. details can be found here: Removing password from Phoenix BIOS and HDD.
Question: my laptop does NOT turn off. How to fix it?
Answer: first of all, you should install the KB909667 patch (download / download). If this does not help, then it is worth updating the drivers for the video card. details can be found here: Modification of the ATI video card driver for installation on a laptop and here: Modification of the nVidia video card driver for installation on a laptop.

Questions that are related to laptop memory
Question: I have 4 GB of RAM in my laptop, but why does Windows only show three?
Answer: the point is that 32-bit operating systems do not “see” more than 3 GB. This is due to the limitation of the address space. You can read more about this here: Windows x86 or x64. What is better to install on a laptop? If you still have a 64-bit version of Windows, but the system still does not see more than three gigabytes of memory, then you should update in the laptop BIOS or enable the 4Gb Remapping option in the BIOS, if there is one.
Question: why some programs show that my video card only has 8 (64, 128, 256, 512, 1024) megabytes of memory. The laptop indicates that there is much more of it. What is the reason?
Answer: the fact is that laptop video cards use both their dedicated memory and can use part of the laptop’s RAM for their own needs. This process is automatically controlled by the video driver. If the video card needs more memory than it has, the video driver allocates additional memory from the laptop’s RAM. This process is completely automatic. Let’s take the GMA950 video card built into the chipset as an example. It has only 8 MB of its own memory, but if necessary, the video driver allocates up to 384 MB of RAM to it. Manufacturers often like to summarize the video card’s own memory and the maximum amount allocated from the RAM. This makes a bigger figure :).
Question: I have a 160 (250, 320, 500) GB hard drive in my laptop, but the system shows that the volume of the hard drive is only 147 (232, 298, 477) GB. Where did the piece of memory go?
Answer: The reason is simple. Hard drive manufacturers believe that 1 KB = 1000 bytes, 1 MB = 1,000,000 bytes, 1 GB = 1,000,000,000 bytes, and so on. Software developers assume that 1 KB = 1024 bytes, 1 MB = 1048576 bytes, and so on. So it turns out that the 160 GB hard drive has a capacity of 160 billion bytes, or approximately 147 GB. Also, hidden partitions can be a prerequisite for the loss of disk space. Read more about them here: Working with the automatic Windows installation on a laptop.
