Laptop discharges quickly. what to do?
If your laptop battery runs out of power quickly, the reasons can be very different: from simple battery wear to software and hardware problems with the device, the presence of malware on the computer, overheating and similar reasons.
In this material. in detail about why a laptop can quickly discharge, how to identify the specific reason that it is discharging, how to increase its battery life, if possible, and how to preserve the battery capacity of a laptop for a longer period.

Programs affecting laptop battery drain
Energy is consumed in one way or another by all programs running on the computer. However, the most common reason that a laptop runs out of power are programs in autostart, background programs that actively access the hard disk and use processor resources (torrent clients, automatic cleaners, antiviruses, etc.) or malware.
And if you don’t need to touch the antivirus, you should think about whether it is worth keeping the torrent client and cleaning utilities at startup, as well as checking your computer for malware (for example, in AdwCleaner).
Additionally, in Windows 10, in the Settings. System. Battery section, by clicking on the item “See which applications affect battery life”, you can see a list of those programs that consume the laptop battery the most.
For details on how to fix these two problems (and some related ones, for example, OS crashes), you can read about Honor in the instructions: What to do if the computer slows down (in fact, even if the laptop works without visible brakes, all the reasons described in the article can also lead to increased battery consumption).
Laptop battery worn out
The first thing you should pay attention to and check when reducing battery life is the degree of deterioration of the laptop battery. over, this may be relevant not only for old devices, but also for recently purchased ones: for example, frequent battery discharge “to zero” can lead to premature degradation of the battery.
There are many ways to do this, including the built-in laptop battery report tool in Windows 10 and 8, but I would recommend using AIDA64. it works on almost any hardware (unlike the tool mentioned earlier) and provides all the necessary information even in the trial version (the program itself is not free).
In the program, in the “Computer”. “Power supply” section, you will be able to see the main points in the context of the problem under consideration. the passport capacity of the battery and its capacity when fully charged (i.e., the initial and current due to wear and tear), another item “Degree of deterioration “Displays the percentage of the current full capacity below the passport.
Based on this data, one can judge whether it is the wear and tear of the battery that causes the laptop to quickly discharge. For example, the claimed battery life is 6 hours. We immediately subtract 20 percent for the fact that the manufacturer provides data for specially created ideal conditions, and then subtract another 40 percent from the resulting 4.8 hours (the degree of battery wear), leaving 2.88 hours.
If the battery life of the laptop roughly corresponds to this figure with “quiet” use (browser, documents), then, apparently, it is not necessary to look for any additional reasons, in addition to battery wear, everything is normal and the battery life corresponds to the current state battery.
Also keep in mind that even if you have a completely new laptop, for which, for example, the battery life is 10 hours, you should not count on such figures in games and “heavy” programs. 2.5-3.5 hours will be the norm.
Dust and overheating of the laptop
And one more important point that can affect how quickly the battery on a laptop sits down. dust in the case and constant overheating of the laptop. If you almost constantly hear the fan of the laptop cooling system spinning wildly (however, when the laptop was new, you could hardly hear it), think about fixing this, since even rotating the cooler at high speeds causes increased power consumption.
In general, I would recommend contacting specialists to clean a laptop from dust, but just in case: How to clean a laptop from dust (methods for non-professionals and not the most effective).
Power management drivers
Another common reason for a laptop’s low battery life is the lack of the required official hardware drivers and power management. This is especially true for those users who independently install and reinstall Windows, after which they use the driver-pack to install drivers, or do not take any action to install drivers at all, since “everything works like that”.
The hardware of most manufacturers’ laptops differs from the “standard” versions of the same hardware and may not work properly without those chipset drivers, ACPI (not to be confused with AHCI), and sometimes additional utilities provided by the manufacturer itself. Thus, if you have not installed any such drivers, and rely on the message of the device manager that “the driver does not need to be updated” or some program to automatically install the drivers, this is not the right approach.
- Go to the official website of the laptop manufacturer and in the “Support” section find driver downloads for your laptop model.
- Download and install manually hardware drivers, in particular the chipset, utilities for interacting with UEFI if available, ACPI drivers. Even if the available drivers are only for previous versions of the OS (for example, you have Windows 10 installed, but only for Windows 7 are available), use them, you may need to run in compatibility mode.
- Check out the descriptions of BIOS updates for your laptop model posted on the official website. if among them there are those that fix any problems with power management or battery discharge, it makes sense to install them.
Examples of such drivers (there may be others for your laptop, but from these examples you can roughly guess what is required):
- Advanced Configuration and Power Management Interface (ACPI) and Intel (AMD) Chipset Driver. for Lenovo.
- HP Power Manager Utility Software, HP Software Framework, and HP Unified Extensible Firmware Interface (UEFI) Support Environment for HP Notebooks.
- ePower Management Application plus Intel Chipset and Management Engine. for Acer notebooks.
- ATKACPI driver and hotkey-related utilities or ATKPackage for Asus.
- Intel Management Engine Interface (ME) and Intel Chipset Driver. for almost all laptops with Intel processors.
However, keep in mind that the latest OS from Microsoft, Windows 10, may “update” these drivers after installation, returning problems. If this happens, the instruction How to prevent updating Windows 10 drivers should help.
Note: if device manager shows unknown devices, be sure to figure out what it is and also install the necessary drivers, see How to install an unknown device driver.
Additional information on laptop discharge
And some more information on the topic of the battery, which may be useful in cases where the laptop is quickly discharged:
- In Windows 10, in “Settings”. “System”. “Battery” you can enable battery saving (enabling is available only when running on battery power, or when a certain percentage of charge has been reached).
- In all the latest versions of Windows, you can manually configure the power scheme, energy saving options for different devices.
- Sleep and hibernation, as well as shutdown with the “quick start” mode enabled (and it is enabled by default) in Windows 10 and 8 also consume battery power, while on old laptops or in the absence of drivers from the 2nd section of this manual can do it quickly. On newer devices (Intel Haswell and newer), if you have all the necessary drivers, you don’t have to worry about discharging during hibernation and shutting down with fast startup (unless you intend to leave the laptop in this state for several weeks). Those. sometimes you may notice that the charge is being wasted even when the laptop is turned off. If you often turn off and do not use your laptop for a long time, while Windows 10 or 8 is installed, I recommend disabling Fast Startup.
- If possible, do not drain the laptop battery to full discharge. Charge it whenever possible. For example, the charge is 70% and it is possible to recharge. charge. This will extend the life of your Li-Ion or Li-Pol battery (even if your old school “programmer” friend claims otherwise).
- Another important nuance: many have heard or read somewhere that it is impossible to work on a laptop from the mains all the time, since a constant full charge is harmful to the battery. This is partly true when it comes to storing the battery for a long time. However, if we are talking specifically about work, then if we compare the work all the time from the network and work from the battery up to a certain percentage of charge with subsequent charging, then the second option leads to many times more severe battery wear.
- Some notebook computers have additional battery charging and battery life options in the BIOS. For example, on some Dell laptops, you can select a work profile. Mainly On Mains, Mainly On Battery, adjust the percentage of charge at which the battery starts and ends, and select which days and times to use fast charging ( it wears out the battery to a greater extent), and to what extent. the usual.
- Just in case, check for auto-turn-on timers (see Windows 10 turns on itself).
This, perhaps, is all. Hopefully, some of the tips below will help you extend your laptop battery life and battery life on a single charge.
The next common culprit in this issue is the laptop battery itself. Modern lithium-ion components have much better characteristics than those installed 15-20 years ago, but at the cost of this increased technical complexity and, as a result, an increase in the likelihood of breakdown. Each battery has its own microcircuit, which is responsible for the process of charging and delivering energy to the main device. it can fail due to inaccurate handling or voltage drops.
Ordinary wear cannot be ruled out either. alas, but batteries are also not eternal and have a certain service life, usually measured in charge and discharge cycles. A badly worn battery can show symptoms like the ones under consideration, so if the laptop is old enough (more than 7 years in use) and the battery in it has not been changed, it should be replaced to solve the problem. It is also worth doing if you suspect a breakdown. alas, in most cases, repairs are economically inexpedient.
Failure of the power controller
Without exception, all portable computers have a special microcircuit that is responsible for the process of interacting with the battery. the power controller. One of its tasks is to charge the battery, and a symptom of a problem is the inability to recharge it if the laptop is on. At home, such repairs are almost impossible to perform, so the only sensible solution would be to visit a service center.
Unsuitable power supply
Often you can find a situation when a laptop does not have a standard means for charging, for example, if the device was purchased second-hand without a kit. Users get out of the situation in different ways, most often they select either a universal unit with removable plugs or a similar one from another model of the same manufacturer, or even from a device from a completely different vendor. In most cases this does not cause problems (there is some standardization, and sometimes the power supply devices may well be compatible), but it also happens that charging turns out to be inappropriate: it gives out the wrong voltage and power values, as a rule, lower than required. Because of this, in a running state, the laptop does not charge, but when the power is off, it may be quite enough. The solution in such a situation is obvious. purchase a complete power supply unit or at least its full analogue.
Defective power supply
If the laptop has a regular charge, the matter may be in its breakdown: one or another component, most often a transformer, may fail, which is why the output current began to differ significantly in characteristics from the required one. You can find out with the help of a multimeter: put the device into the voltage diagnostics mode, connect the power supply unit to the electrical network and check how many volts it gives out.
In the case of values below nominal (for example, 10 V at standard 19 V), this is an unambiguous sign of a breakdown. As a rule, it is very difficult to repair such equipment at home, so a visit to a repair shop would be the best solution. Some difficult cases may require replacement.
The least common failure under consideration occurs for software reasons in the form of an incorrect power configuration by means of the operating system itself.
- Most often, this behavior manifests itself in devices in which the OS was updated to a newer version: for example, it was originally Windows 7, and then Windows 10, but without a complete reinstallation. In such a situation, it is worth resetting the system to the factory parameters, and if this does not help, reinstall it with full formatting of the main drive.
Sometimes the cause of the problem in question lies in the incorrect configuration of the power scheme. This can be eliminated either by the system reset already mentioned above, or, if this is not possible, by manually checking all the parameters and setting the correct values.
The final source of software failure is lack of required drivers. On some laptop models, the power controller requires the system utility software to function properly. As a rule, it is quite simple to make sure of this. you need to open the “Device Manager” and see if there are any items with an error in it, especially in the category “System devices”.
If any are found, use the component ID to locate the software package using the guide at the link below.
Finally, we remind you once again. the problem under consideration arises less often for software reasons, and first of all it is worth checking the hardware of the laptop.
Faults in the power supply unit (plug, connection cable)
The problem arises during long-term operation of equipment. The situation is as follows: the charger is connected, but does not charge on the laptop, and a notification appears in the messages to the user (in the tray). “Connected, not charging” or “Charging not in progress” (for Windows 10). Initially, it is worth making sure that the cable is correctly connected to the port, the plugs are installed in the outlet. If there are no errors, proceed as follows (valid for ASUS equipment and devices from other brands):
- turn off the laptop;
- disconnect the power supply cable;
- dismantle the battery;
- install the power supply cable;
- press “ON” on laptop keyboard.
If the technician does not respond, it means that the power supply unit and / or cord is defective. The situation can be corrected by replacing worn parts.
The battery may not be the problem
The difficulties that have arisen with the power supply do not always lie in the autonomous power source. This can be determined at the stage of inclusion. In the event that the device suddenly stopped giving signs of life when turned on, you need to pay attention to the integrity of the electrical circuit of the portable charging, as well as to the outlet to which it is connected.
To begin with, it’s worth examining the situation, adhering to a simple algorithm:
- check the functionality of the outlet;
- check the connection of the cords and the correctness of the connection of the connectors;
- determine the absence of problems with the power supply and cable;
- check the presence of a charge in the battery itself, if it is removable and replaceable. To do this, you can use a tester or a flashlight bulb with suitable characteristics.
It often happens that a disconnected wire or a network cable that is not fully inserted into the connector leads to a rapid discharge. Particular attention should be paid to the integrity of the cable itself, since its regular use can lead to deformation of the wires near the connectors and the subsequent breakage of the contacts.
If the issue has not been resolved, then it is obvious to assume that there are certain problems with the power supply. You can check the electrical circuit yourself using a special tester.
To check if the charger is working properly, you can use the same one from another laptop PC. If, when connected, the laptop also does not show signs of life, then a breakdown in itself or in autonomous power supply.
What to do, the laptop battery has stopped charging
But there are cases when the battery stopped charging on an almost new laptop and the operating system writes that “The battery is connected but not charging”:
Why the laptop won’t turn on after sleep mode
Now we will discuss why the laptop does not turn on after hibernation. The device is initially configured so that after a certain period of time, the computer will automatically activate hibernation. If you manually close the lid of a laptop, it will often go to sleep as well. In this case, in some cases, the laptop may not return to work after hibernation.
- broken motherboard;
- drivers are not working correctly;
- the battery is out of order;
- battery low
In some laptop models, the power button is responsible for waking up from sleep mode. In such a case, using a keyboard or mouse is useless. If the computer continues to sleep while using the power button, additional steps are required. You can independently solve almost any problem due to which the laptop may refuse to wake up.
An exception is the failure of the motherboard. If it is out of order, you will have to contact the service center for help. One of the most common reasons for not returning from sleep is battery depletion. If the battery is critically low and the laptop goes into sleep mode, plugging in the charger can bring it back to life.
The algorithm for resetting it is already familiar to us: we disconnect the laptop from the power supply, take out the battery, hold the Power button for half a minute. After a short time, we return the battery to its place and turn on the laptop.
The BIOS and hardware elements cause the laptop to fail if a variety of sounds are heard when trying to start up, including those that were not there before. When the computer makes an attempt to start, but at a certain stage of the system boot, it fails, the problem lies in the hard disk or the loss of part of the system files. The matrix inverter and the backlight lamp are two elements of the laptop that fail which hello to the fact that we will not see the operating system loading on the screen, even if it happens. The failed parts will have to be changed and the operating system reinstalled. If you find the exact reason for the failure of the laptop, it can be brought back to life with the least loss.

Battery only charges when Laptop is off (3 Solutions!!)
Factory defective charger or battery initialization errors
A notification that the battery is not charging may appear on a brand new device as well. Reasons 2. battery defect and its incorrect initialization. In the first case, only the purchase of a new component will help (exchange and replacement under warranty). It is wiser to entrust the battery malfunction check to a service center representative. In the second case, if the laptop does not charge from an Acer charger or another brand, you need to do this:
- turn off the device and disconnect from the network;
- remove the charger (if it is removable, you do not need to untwist the case);
- hold the ON button for 20-30 seconds;
- install the battery;
- connect the device to the network;
- turn on the equipment.
When using HP technology (new or already used), it is turning off and on the device that is the most effective way to solve the problem. If after that the laptop battery does not charge, the reason is different, for example, the power supply. It is better to provide the diagnostics to the master of the service center.
Private method without removing the battery: turn on the equipment, remove the charge, click on “ON.” until the laptop shuts down completely and another 60 seconds. Install charging. Do not touch the technique for 15 minutes. Enable.
The processor in the laptop is overheated
Overheating of the processor in laptops is the most common problem. Especially Acer laptops with an AMD processor suffer from it.
The BIOS has a protection that turns off or reboots the laptop if the maximum available temperature is exceeded, thanks to which the processors do not burn out from overheating.
Intel has its own overheating protection in the new processors, which does not restart or shut down the laptop, but simply resets the frequency. This action is called throttling.
The temperature of the laptop can be checked in the Everest program, the Trial version can be downloaded from the link, you can also check whether the processor is throttling or not.
If, under load, cold air flows from the cooler and the temperature rises, then it is urgently necessary to change the cooling system. The pictures below show how to find out the temperature and throttling of the processor using the Everest program.
You can also use the AIDA64 program, you can download the test version “Here”
Why the battery won’t charge at all?
Initially, we note that laptops of any brands, including Acer and Asus, may not be charged. There are many reasons for the malfunction. The main task of the user is to carefully monitor the parameters and notice the reaction of the operating system to a problem. Where can I see her? In the tray on the Start panel. In the part of it where the volume indicators, Internet connections, language block are located, there is also a battery charging icon. When you hover over it with the mouse cursor (in later versions, automatic pop-up messages appear), it is easy to see the percentage of charging, parameters and notifications.
BIOS power management issues
After updating the Windows operating system or an incorrect shutdown of equipment (for example, a power surge), the user may notice that the laptop is not charging from the charger, and a corresponding notification appears in the tray. It is often impossible to trace what exactly caused the failure, therefore, the malfunction is eliminated by a universal method. resetting the BIOS parameters. Algorithm of actions (valid for all brands of devices):
- turn off the laptop;
- disconnect from the power source (network);
- remove the battery;
- press the “ON” button and hold it for 1 minute;
- turn on the laptop to the network (without placing the battery in the case);
- go to the BIOS while holding the function key on the keyboard (Del, F2 or F12. depending on the manufacturer);
- reset settings through the Exit menu. here you need to select the Load Defaults item (there may be other options on the main page, for example, Load Optimized Defaults or Load Fail-Safe Defaults);
- save changes on exit;
- turn off the laptop;
- install the charger, the power cord to the power supply.
- turn on the device.
