How to properly set up a laptop power supply from battery or mains
The main advantage of a laptop is that it is able to work autonomously, thanks to the use of the battery. In connection with this opportunity, many users have their own criteria for the duration of laptop battery life.
Users who work long hours without being able to connect to the network require lower power consumption of the notebook. Also, to increase the operating time, it is possible to use a spare battery, which can be purchased separately.
Our article invites you to familiarize yourself with the recommendations of laptop repair masters on the system settings of laptop power plans, as well as the dependence of the operating time on some characteristics.
The autonomous work of any laptop depends on several factors and system settings:
the number and characteristics of tasks that are performed on a laptop.
System icons, namely “battery status” are necessary in order to determine the charge level as well as the remaining runtime. In case of autonomous operation, a low battery level requires connection to the power supply. The Windows 7 operating system allows the user to glean a lot of the most accurate information about the battery and the state of the battery. The system icons are displayed on the right side of the taskbar area, as well as the battery indicator, which in some cases can have several indicators. Each individual indicator belongs to one of the autonomous power sources. Accordingly, one charge level indicates that your laptop has only one energy source (battery), if there are several such charge indicators, then there are several power sources.
To check the battery charge data, simply hover the mouse over the corresponding system icon. In the notification window that appears, you will see the charge level, which is displayed as a percentage, as well as the remaining battery life, which is displayed in hours and minutes. The battery status notification in some mobile devices may be immediately displayed on the desktop, and not in the “taskbar” area. The battery status icon shows the percentage value in the corresponding color. So when the battery is charged more than 25%, we can observe the display of the green color of the icon.
While the charge level drops below 25%, we see a yellow triangle with an exclamation mark inside it on the system icon. When the charge drops to 10 percent, the icon changes its color to orange. The system icon displays the 7% battery level with a red cross in the form of the letter “x” and an additional notification about the need to connect the battery power source, and at 5% your laptop will go into a special “hibernation” mode. All content is saved on the desktop in the hard disk memory, but the laptop power is turned off.
In order to check the battery charge level, click on the system icon “battery status”, as a result of which a window with indicators of all available batteries will appear on the screen. At the same time, the indicator has many useful functions in its structure, this is the battery charge level, and the choice, setting or creation of a laptop power plan, and setting the overall screen brightness, and using parameters that save power consumption.
We bring to your attention a detailed description of all the options for setting up a laptop power plan. As we already said, the battery life of a mobile computer is one of the important criteria for choosing and buying a laptop. And you can increase this time using the standard settings, defining your special parameters for the laptop power plan. These plans are a collection of characteristics of how the system manages power. This control includes various parameters on which the process of energy consumption depends. There are several such control plans and they depend on how and with what intensity you work, as well as on whether your computer is connected to the power supply network or not. So, for example, you can adjust the period of time after which the monitor will turn off, and then turn off the power to the hard disk. This setting is quite important at the moment when you leave the laptop, but the battery power will remain, since the power consumption will be turned off automatically after a specified time. Standard power plans allow you to choose one of three options:
save energy consumption as much as possible and increase operating time; 2. to ensure system performance at the maximum level; 3. balanced work of the computer. Each user can choose the option that best suits his needs. The same schemes are customizable, and you can change any parameter for your specific purposes. Some manufacturers may have more standard power plans. As a rule, loading and operation in any operating system occurs by default with a balanced power scheme. Sometimes your computer needs to be repaired to restore battery performance.
“Balanced” energy plan. This scheme is aimed at ensuring that the system works as quickly as possible, but at the same time saves energy at a time when you are not performing any active actions, that is, you are not working.
Energy Saving Power Plan. It is that the system uses the minimum amount of power, and savings are achieved by lower PC performance. The main goal of this nutritional management plan is to maximize uptime.
Energy plan “High performance”. This power supply scheme is aimed at maximizing the efficiency of the PC. The main requirement of this scheme can be considered that the laptop must be connected to the power supply network and your PC does not need to conserve battery power. If this scheme is used by the user during autonomous operation of the PC, then we can note the rapid discharge of the battery. Windows 7 operating system uses high performance schema by default, which is not displayed in the system indicator.
In order for this scheme to be displayed on subsequent switching on, it is necessary:
open the link “Additional power options”;
in the “Power supply” window, select the line and click on it with the mouse “Show additional plans”.
As we have already determined, each power plan has a lot of parameters that ask the system how to manage power consumption, when and after what period of time to disable certain functions that are not used. In the event that the standard settings of these plans do not suit you, you can create your own, while relying on the standard parameters. You can customize each power plan in the Power Options section. Changing both basic and advanced settings will help you optimize your laptop and its performance in accordance with the nature of your work and PC use.
In order to make it easier to return to the standard settings of the parameters, we recommend creating new power schemes, and not changing the standard ones. In order to change the circuits among themselves, you need to set the switches of the required circuits on the indicator. In order to change any parameters of one of the schemes, you need to go to = link “Additional power options”, which will open the “Power supply” settings window.
This window allows not only to make a choice from the existing plans, but also to reconfigure any plan. The window also contains a slider at the bottom that allows you to change the brightness of the screen, which changes the brightness of the image. As the screen brightness increases, so does the battery drain. On the left side of this window, you can configure individual parameters that will be valid regardless of which scheme you choose. The most relevant are the settings for actions when you press the power button, sleep mode or actions with the laptop lid. So, the system can go into sleep mode when closing the lid or pressing the “Sleep” button in order to save battery power. It is worth noting that these settings differ for the laptop’s autonomous operation or operation from the power supply network and you need to configure these parameters.
The Sleep button, power button, or closing the lid can cause one of the following:
“No action required”, which means that the system will not make any changes to the operation of the PC;
“Sleep”, provides for the transition of the PC to sleep mode. This achieves a significant reduction in the use of battery power, despite the fact that all operating functions are saved in the laptop’s RAM;
“Hibernation” means that the PC goes into hibernation mode automatically. At this time, all documents and programs that were opened are saved on the hard disk (as opposed to the “sleep” mode), and the laptop is turned off. This mode provides the minimum consumption of energy consumption. It is recommended to use this mode if it is not possible to charge the battery and you will not be working on this PC for a long time;
Completion of work. the laptop conducts an automatic shutdown. When the laptop enters sleep mode, the system may ask for a password. You can configure this setting in the Password Protection on Wakeup window. Almost all settings for screen brightness, dimming or turning off the display must be configured for the laptop to work, both on battery and mains. You can customize the time to turn off the display in the next window “Power supply” = “Configure display off” = new window “Change plan settings”. Here you need to choose after what time the system will automatically dim and turn off the display. This time is always counted from the moment when you stopped performing any actions on the PC.
The next setting relates to the application of “Sleep”. This allows you to keep your work as you leave it, but at the same time your PC significantly saves power consumption. Also, to conserve battery power, you can adjust the brightness of the display, because the lower it is, the less power consumption. For these purposes, you need to use the slider responsible for brightness.
The Change advanced power settings link allows you to configure all power settings. When you click on the link, a new window will open in which the “power supply” dialog will be located. As a rule, standard settings and parameters allow you to adjust the operation of the system, its performance and battery consumption time for specific purposes and work. But it may also happen that you need to create your own power plan. For this there is a separate link “Create power plan”. The dialog will be similar to the name of the link. First of all, you must come up with and enter the name of your plan in the appropriate line, and then choose on the basis of which standard parameters you will create it.
Then we press “Next”, after which the window “Change plan parameters” opens. In this window, you need to configure the basic power settings, and then save your plan. All additional parameters are available for change in the “Power supply” section. After these steps, your plan will appear in the indicator next to the rest of the standard power plans.
Manual power control of the laptop, which we do even with the automation of power management built into the laptop, consists in monitoring the battery level before turning off the laptop.
Remember that after turning off the laptop, you cannot leave the laptop connected to a charger (connected to a 220V network) if the battery had almost the maximum charge level before disconnecting the laptop.
And remember that after turning off the laptop, you need to connect the laptop to a charger (connected to the 220V network), if before disconnecting the laptop, the battery had almost a minimum charge level. With the subsequent obligatory disconnection of the charger from 220V at the end of the battery charging.
This is the manual control and manual control of the laptop power supply.
All of the above applies only to laptops with a good battery. A defective battery behaves unpredictably. When fully charged, it can suddenly reduce the charge level. It may not reach the maximum charge level, or quickly self-discharge when it is off, etc. Therefore, the instructions for manual control and management of laptop power supply apply only to the lucky owners of working batteries.
Manual laptop power management
The laptop battery is a very important device in the computer. Even if this battery is not really needed. For example, when using a laptop at home or office, where there is always access to a 220V electrical network. It would seem that if you constantly use 220V, and set all the parameters of the laptop’s power supply, then why further monitor the battery charge? After all, everything will happen automatically, as it was described in the article “Automatic laptop power management”.
Users who reason like this are partly right. But not really The point is that due to the importance of the battery as a laptop device, the control of the power supply of the laptop battery does not stop even when the laptop is unloaded and turned off. Why is this done? To charge the battery even when the computer is completely turned off.
Laptop manufacturers believe that if the user forgot to charge the battery, then this should be done automatically, regardless of whether the computer is turned on or the operating system is loaded. The main thing is that the charger is connected, and it, in turn, would be connected to the 220V network.
And all is well, it would seem. Turn off the laptop when we finish working with it. At the same time, do not disconnect the charger from the 220V network. Accordingly, the battery will automatically be charged to 100%, 80% or 50%, depending on how it is determined by the dedicated laptop power management software. Okay? Fine, but
But after charging the battery to the maximum level (100%, 80%, 50%), the charger will not disconnect from 220V. To disable it, you need a person, a user, his human hands. Self-disconnecting chargers are not yet produced (this is something reminiscent of self-donning trousers mentioned in the works of the Strugatsky brothers)!
So what? Yes, the fact that after a while the laptop battery will be somewhat discharged. By her own. Why? Because any rechargeable battery has a so-called self-discharge current. Whether you want it or not, any battery is gradually discharged, even if it does not give off electricity to the outside. And as soon as the charge drops by at least half a percent, the battery charging system will automatically connect the charger. The battery will start charging again to its limit (100%, 80%, 50%).
And so many, many times. Automatically. Without human intervention. The battery will automatically charge to the maximum level. Then it will automatically discharge (self-discharge) to a level slightly less than the maximum. And it will charge again automatically. And so an infinite number of times, until the charger is disconnected from the 220V network.
The described mode of constant recharging of the battery to the maximum level and subsequent small self-discharge is very unfavorable for the battery. Especially if you determine that the maximum battery level is 100%. Continuous recharging of the battery to 100% from a level just below 100% will damage the battery very quickly. This can shorten the battery life by several times.
Therefore, laptop users need to personally monitor the battery level, despite the automation of this process. Apparently, the developers of laptops have not fully taken into account all the features of the operation of batteries, or have not yet come up with algorithms that allow you to do this in the “right” way. Therefore, it remains to finish it with your own “handles”.
How it’s done? Before turning off the laptop, you need to check the battery indicator status. If the indicator shows the maximum charge level (100%, 80%, 50% depending on the settings), or this level is close to these values, differing from the maximum by no more than 1-2%, then immediately after turning off the laptop you need to ALWAYS disconnect the laptop charger from the 220V network. Required!
If the displayed battery charge level is much lower than the maximum (and at the same time you are sure that your battery is in good working order and is able to charge up to the maximum level), then after turning off the laptop, you can not immediately disconnect the charger from 220V. But this shutdown MUST be done immediately after the battery indicator goes out. This indicator will remain on even when the PC is off, it will turn off only after the battery is charged to the maximum level.
If the laptop is in the office, and the user has to leave it after turning off the laptop, then it is almost always necessary to disconnect the charger from 220V. Almost always. Only in one case is it possible and necessary to leave the charger turned on at 220V, if the battery charge level before disconnecting the laptop was close to zero. Because you cannot leave the battery in a completely discharged state for a long time! Long-term storage of a battery with zero or near-zero charge is much worse than continuously recharging the battery to 100%. That is, we choose the best of the 2 worst options! Well, if there is an intelligent security guard (or duty officer) in the office, then ask him (or her) to disconnect the charger from the 220V network, after the battery charge light on your laptop goes out.
So, before turning off the laptop, we make sure that the charge level is close to the maximum, and then we disconnect the charger from the 220V network immediately after turning off the laptop. But if, on the contrary, we make sure that the charge level is close to the minimum (0%.10%), then after turning off the laptop we connect it to the charger (if it was not previously connected to it), and we connect the charger to the 220V network (if it was not previously connected to the electrical network). And we wait (persistently) until the battery indicator goes out. After that, we still disconnect the charger from the 220V network. Ultimately, the charger must be disconnected from the mains.
A laptop that is turned off and left unattended must not be connected to a 220V charger. Should not!
Does the laptop work without a battery?
Is it possible to forget about the existence of a battery at all? And do not remember about it either when the laptop is turned on, or when it is turned off, when the laptop is turned on, or when it is turned off.?
It is possible if this battery is removed from the laptop!
Can a laptop run without a battery at all? Yes maybe. Only in this case, the laptop will actually turn into a stationary PC, which can only work from a 220V network.
When removing a serviceable battery, be sure to check its charge level. It is advisable to remove the battery for subsequent long-term storage if its charge level is between about 50% and 80%. A battery that is completely discharged (0-10%) must not be removed for storage, otherwise this battery can no longer be used, it will fail during storage. It is also undesirable to remove a fully charged battery (100%), it is better to pre-discharge it to at least 80%.
The battery stored separately from the laptop should be periodically (at least 1-2 times a year) checked and recharged to 50%.80%. Otherwise, it can be discharged to a critical level and become unusable in the future.
Laptop slows down when plugged in (when the laptop is charging)
Recently I ran into such a problem that when I recharge my laptop, everything immediately starts to slow down. This was not the case before. The laptop is new, I bought it 2 months ago, about 3 weeks ago it started. When I turn off the charging from the network, then all the rules, the brakes immediately disappear. Can you tell me what could be wrong? Maybe something needs to be reconfigured in the laptop power supply?
Most likely the power plan has been knocked down!
To fix this, click on the battery icon. There, select the power supply parameters and set that when operating on battery power and operating from the network, the performance is as high as possible.
If everything is set to maximum in the settings and so !! ! Then most likely then the problem is in the equipment.
Look at the control panel, power supply, plan settings from the network (recharge). additional parameters, power management of the processor, setting a maximum of 100%, a minimum of 5, well, and other parameters for the maximum (maximum performance) or at your discretion.
I, too, suddenly had this problem out of the blue, and I had already managed to re-read half of the Internet, having tried a bunch of methods, as, suddenly, I saw that I had not tucked the charging plug to the laptop well enough. Start checking with this, because, perhaps, the solution is much easier 🙂
There is the same problem, which I just did not do, I tried everything, and reinstalled it. And at first it was like this. I turn on the game, play for a couple of minutes, then the graphics gradually start to slow down. I turn off the power supply unit and almost immediately stops slowing down. I turn it back on, it slows down again and almost immediately. I cleaned and smeared the paste. Measured the temperature, the temperature is normal, there is simply no reason! Then I figured it out, there is an education as an electrician, but I can figure out something and I got into it. As a result, with an oscilloscope, I found an interesting detail, 2 details! Apparently, the stabilizers, during operation from the network (17 volts), become very hot and reduce the supply voltage, I don’t remember exactly about 0.7 volts, this is a saving mode, the percent at this time works at half strength, or even less. But there is no such thing from the battery, they heat up but not so much.
It also happens when the power supply is covered, too, there are such problems. But I have tried other PSUs with the same voltage. In general, I sin on stabilizers because there was no laptop for half a year. this is a factory marriage for many.
HP ProBook 450 G1, Intel Core i5-4200M, 2500 MHz.
Guys, the same bullshit. It just happened after it was disassembled, cleaned and smeared with new thermal paste.
With charging wire. unrealistically stupid (the frequency multiplier does not rise above 8-9 (100). You pull the wire out. voila, the multiplier jumps from 10 to 25. Everything works quickly. BIOS reset to factory settings.
Who faced the same and solved the problem? Who will advise what?
Guys, Denis Dimitriev wrote everything correctly. Did as he suggested all the brakes disappeared. In general, with a connected laptop, I had 0% of the processor’s performance. I don’t understand how he worked at all. Thank you Denis Dimitriev!
in win10, double click on the battery icon, the system battery settings window will open. When running on battery power, I had maximum performance and The Witcher 3 did not slow down. And when working on the network, there was a balanced mode and there were lags and stuttering. Put Max Productivity everywhere. It kind of helped me
there was the same problem, it’s not even about the equipment, but about the power supply system itself, because at the dacha I’m sitting, everything flies with me and it just flies with charging, but when I arrived home I plugged it into the outlet at home again, the FPS of the power supply from the network began to fall, although dacha everything was fine and from the network. so I will say so that most likely this is a matter of energy supply at home.
for those who slow down the laptop when charging and not only. The main problem may be stupid in the charging unit itself, since in modern times it wears out and may stop giving the necessary amperes to charge the laptop and its operation. Either as an option, you use a non-original charger for your beech (or the seller gave you an inappropriate power supply for the beech), for example, laptops with gaming video cards have a minimum power supply of 120 watts and 6.5 amperes (you can also plug in a 60 watt block with 3. 5 ampere beech will work, but the performance of the SPU or GPU or in the state of the art will upset you, since there is simply not enough amperes for the operation of the equipment
On my laptop there was the same problem, AMD A8 processor with HD8550g graphics, removed the drivers on the video and installed them through the Windows update service without software from AMD, only the system driver and the laptop began to work flawlessly in any mode.
The same problem, everything is twisted to the maximum, I did not overclock the card and I don’t want to. When the laptop is disconnected from the network, the processor works at full strength, and something goes wrong with the network. Even if you put everything with a battery, everything is balanced, the FPS is better, much.
There is a power supply unit near it, there are 2 parts of the charging, pull out and turn it back on, this solution helped me
Excessive heating of internal components is one of the main causes of unstable performance. You can find out that a laptop is overheating in several ways. Firstly, the device does not start to slow down immediately after being turned on. At first the laptop works fine, but after 10-15 minutes, the temperature of the parts becomes critical, and the level of performance decreases. In the event that the heating is too high, an automatic shutdown occurs.
Secondly, you can independently measure the temperature of the computer. The easiest way is to try the case with your hand and compare if it gets noticeably hotter than right after purchase. If the difference is significant, dust has accumulated inside the device, which interferes with normal cooling.
Note! You can find out the exact temperature of various system nodes using the Speccy program.
Too many temporary files
The laptop may slow down due to a large amount of unnecessary information accumulated in temporary directories. Its search and removal are performed using one of the special utilities for cleaning the system, for example CCleaner. This free app has a simple interface and ample cleaning and optimization options.
In the Cleaning section, select the areas to scan. Then click “Analyze” to start searching for temporal information.
At the end of the analysis, click the “Cleanup” button. All found information will be deleted from the computer. The duration of this process is from 10 seconds to several minutes.
Also, CCleaner is used to clean up the Windows registry. This feature is available in the “Registry” tab. Click the “Search for problems” button to start the check. Found software faults will be added to the table on the right side of the window. At the end of the search, the “Fix” button will become available. Click it and select if you want to save backup copies of the changes made.
Important! Saving backup copies of deleted recordings is an optional step. In the overwhelming majority of cases, the program works correctly, and only those registry values that have lost their relevance are deleted.
In the next window, you can familiarize yourself with the found problems and the proposed methods for fixing them. Switching records is done using the buttons “”. On each page, you can click “Fix”. To correct all incorrect entries in the registry at once, click “Fix marked”.
A large number of running applications
Each open program consumes a different amount of system resources. Among them. processor time, data storage in RAM, disk access. The more applications are running on a laptop, the slower it will run. Excessive amounts cause the laptop to slow down. To avoid this, close unused windows and programs instead of minimizing them.
The current level of system component usage is available on the Performance tab. Here you can see the graphs of resource use, as well as the percentage of utilization at the moment.
The main reasons for the slowdown of the laptop
The main reasons for laptop slowdown are system congestion and pollution. At the same time, pollution can be both physical (a large amount of dust inside the case) and software. It is caused by malware and temporary data accumulation.
Incorrect power supply parameters
The Windows operating system includes power saving features for notebook computers. In addition to reducing the brightness level of the display, they can limit the use of system resources. At the same time, the laptop runs slower, but uses less energy. This allows you to extend the battery life.
But if the device is always connected to the network, there is no point in increasing the battery life. Instead, performance is important to keep the laptop from lagging. Click on the battery icon in the tray and turn off battery saving mode. The link in the same menu opens additional power options.
This is the period after which the computer will go into sleep mode if there is no user activity. These parameters are set separately for battery and mains operation. It is recommended to turn off the automatic switch to power saving mode so that the laptop does not slow down, even if programs are running while you are away. The link at the bottom of the window will take you to setting up custom energy saving schemes.
Such schemes are configured not only manually, but also using special utilities from the laptop manufacturer. To change the current settings, click “Power scheme settings”.
In this section, you can adjust the brightness when operating on battery and mains, change the time the display turns off when idle. options are provided by the “Change advanced power settings” menu. If necessary, open it and set the maximum values when working from the mains so that the laptop does not slow down.
Lots of startup programs
Each time the operating system boots, a set of programs added to the autostart list opens. You can view or change this list on the Startup tab in Task Manager. The “Status” column indicates whether the application’s autostart is currently enabled. This property is changed through the context menu. The last column is Load Impact. It displays how many system resources the program being launched is using.
Out of RAM
Unlike desktop PCs, laptops do not have a modular build system. Upgrading them is more difficult, since most of the parts are soldered to the motherboard. Only the hard disk and RAM are easily replaced. Therefore, if the device slows down, check the memory load and, if necessary, replace it with larger modules.
The current RAM usage is checked in the resource monitor. It is launched by clicking the “Open Resource Monitor” link on the “Performance” tab in Task Manager. The left part of the window consists of a table of memory consumption by various processes and a diagram below it. Using the table, you can determine how much data the applications are using. On the right, there are graphs of RAM usage and allocation, as well as physical memory page errors.
