Users of portable PCs, such as laptops or netbooks, often face one common problem: when the laptop is turned on, the battery does not charge. In this case, the LEDs work, the device does not display critical error messages and. The only difference is that there is a message about the battery in the tray: “connected, not charging”. How to make the battery on a laptop charge, we will consider in this manual.

A common glitch: the battery on a laptop has stopped charging

Those who often deal with computer equipment have long known: "glitches" and buggies can occur for no apparent reason. This is true for both the OS (and not only Windows) and the hardware. The good news is that the overwhelming majority of such "breakdowns" can be eliminated by simply rebooting the device. If the laptop writes: "the battery is connected but not charging", it will not be superfluous to disconnect the battery and insert it back. To do this, just turn the device upside down and open one or two latches holding the battery. Remove the battery so that its connectors stop touching the laptop connectors, then insert it back. The device should work normally the next time you turn it on.

Why the laptop does not charge the battery: method two

If this happens, and the charging is connected, the owner can help out by resetting the BIOS settings. This is explained by the fact that after a failure, the device may incorrectly detect the battery. This often happens if the user leaves a laptop or netbook connected without a battery, and also changes the "native" battery for a new one. To reset BIOS settings, you will need:

• - Turn off the device.
• - Remove the battery (see above).
• - Disconnect the charger from the network.
• - Press the power button of the device and hold it for 60 seconds.
• - to a power outlet without a battery.
• - Press the power button, go to BIOS.

In case the battery on acer laptop is not charging, just press the F1, F2 or Del button. If the battery on an asus laptop is not charging, press F2 or Del to start the BIOS. When the battery is connected, but not charging in the Lenovo laptop, the BIOS menu is invoked by pressing the same keys or F12. And if HP - just press the same buttons or Esc. In other brands of laptops or netbooks, the BIOS menu is called by pressing all the same buttons during boot. Carefully read the labels in the start menu: usually there is a hint at the bottom of the screen which key combination should be pressed.

• - Find the Load Defaults item (most often it is located in the EXIT menu). This will apply the default hardware settings, that is, the optimal ones for this device.
• - When the BIOS prompts you to save the settings, click "Yes", then turn off the device. To do this, just hold the power button for 10 seconds.
• - Disconnect the charger, then insert the battery and turn on the device.

Usually, after executing such a simple algorithm, Windows reports that the battery has been detected and is charging correctly.

Laptop battery won't fully charge: what should I do?

Manufacturers often shove various useful utilities onto the installation disc that serve to increase the device's performance or its lifespan. These include energy managers. These programs serve to extend the life of the battery, almost always at the expense of incomplete charging. This is the main reason why the laptop battery does not fully charge.

If the battery on your laptop is charging 60 percent or less, it's worth looking for and removing excess software. Typically, such programs contain the brand of the laptop in the name. For example, if the battery on an acer aspire laptop is not charging, you should look for the Acer Power Management utility, and if an incomplete charge is on the asus laptop, then, accordingly, Asus Power Management.

To find these utilities, launch Control Panel after clicking the Start button.

All software is located under "Programs and Features"

Select the utility that does not allow you to fully get the battery charge, and click the "Delete" button. The device may need to be rebooted.

New battery: why is the laptop battery not charging?

If these methods did not help and you decide to buy a new battery, an unpleasant surprise may await you here too. If a new laptop battery is connected but does not charge, first of all, make sure that the marking of the new part is completely consistent with the marking of the old one. If everything is correct, in most cases the algorithms described above help.

All of these methods help in most cases when the laptop battery is dead and won't charge. When, after your "dancing with a tambourine," the laptop still does not see the battery, you will need to intervene in the hardware - the power controller may have burned out. And it is better to entrust the procedure for its replacement to experienced specialists.

Laptop battery - 90% available (plugged in, not charging)

In this situation, it is not clear who is cunning - hardware or Win 7. New Fujitsu laptop ... The battery is charged to a state of 90% capacity, and then it is not charged. When the power supply is connected, in the tooltip, when you hover the cursor over the charge manager, I see the inscription: "90% available (connected, not charging)". What is this nonsense? Previously charged up to 100%. I ask you to help with friendly advice. Thanks in advance.

This is a protection system on many laptops now it is charging only up to 90 so as not to spoil the battery with long useless loads, that is, when the laptop is 100% charged, the battery deteriorates.

Discharge the battery below 90% and charge it - it will go to 100%.

Perhaps your battery is set to "economy mode", I can't figure out how to call it correctly. It was installed on a Samsung laptop - there was the Easy Setting utility, where 80% was set by default in the settings, but you could set your own value. It also only charged 80%. When I turned it off, I began to charge up to 100%.

It often helps to remove and insert the battery. It is possible (and even desirable) to reboot the laptop at the same time. This method works especially often with new laptops.

The battery may not charge up to 100% for several reasons. First, if a load is connected to the battery, which constantly draws current. Second, if there is an abnormally high self-discharge current. There can also be anything here, for example, some irreversible processes in the battery itself (in other words, you need to change the battery). Thirdly, the cause may be an unexpected high leakage current, for example, caused by some kind of dirt. In this case, wipe with alcohol.

Manufacturers are constantly improving old and introducing new technologies, which cause problems for users who are accustomed to some kind of traditional solutions. On the forums and in the comments, the same question is often encountered - why does the battery charge up to 80%, although it was always 100% before? If you click on the tray icon, you will see the following message:

80% available (plugged in, not charging)

Many people begin to blame the battery for everything, or even buy a new one without understanding the problem. Someone remembers that they pressed OK in a pop-up window with some text about the battery.

In fact, the solution to the problem is quite simple and elegant. As a rule, laptop owners are faced with a laptop battery charge of up to 79% or 80%. The Korean company for extending the battery life allows them to be partially charged, and this actually increases their lifespan. However, if you have a new laptop that you plan to use for no more than two to three years, this option will be controversial for you in terms of practicality.

How to get your battery back to 100%

If the battery life of a laptop away from the outlet is important to you, and not the extended battery life, then it would be logical to disable this "green" option. This can be done in the following ways.

Open up Start - All Programs - Samsung - Samsung Battery Manager and in the running utility, turn off charging to 80%.

If you do not have this utility installed, open Start - All Programs - Samsung - Settings and set the required parameters in it (tab Power Management - Battery Services).


If you do not have this utility, then try to find it by other names: Battery Life Extender, Easy Setting, Battery long life... To do this, open Start and enter the name in the search bar.

If you still did not find anything similar, the last option remains - you can change this parameter in BIOS... When you turn on the laptop, go to BIOS using the button F2 or another one provided in your laptop.

In the tab Advanced we need a parameter Battery Life Cycle Extension.
Enabled- inclusion, charge up to 80%.
Disabled- shutdown, charge up to 100%.


After setting the desired parameter, save the changes and exit the BIOS. Other manufacturers of mobile computers also use this technology, but they implement it in a slightly different way - the controller is responsible for the incomplete charge of the battery in them, and the user cannot change anything on his own. At the same time, in order not to confuse the user with a charge of 80% or 90%, the operating system will show a level of 100%.

Laptops are, first of all, rather compact mobile devices. In other words, these are computers that you can carry with you. However, they instantly lose their mobility when the battery stops charging. Today we will tell you what to do if the laptop battery is connected but not charging. Fortunately, the problem does not always have to be fixed by replacing the battery - often it is a matter of system errors, third-party software, or even problems with BIOS settings. In any case, we will try to help you save money on purchasing a new battery.

Charger problem

To begin with, we suggest that you check the charger itself. Quite often, many in a hurry forget that sometimes the problem may lie in the charger. You can check it literally in a matter of seconds, if you have a second charger at home, a laptop with exactly the same connector and a working battery. But what if none of the above is present? Then we suggest you do the following:


Well, in this case, s / y, as the cause of the malfunction, we can exclude. What else could have a detrimental effect on battery charging?

Removing third-party software

Few know that third-party software can cause this mess. In principle, the same remark is also true for the official software - an error can creep in everywhere that will not allow charging the battery when the charger is connected. So, let's figure out how you can uninstall the software:

As you can see, there is nothing complicated about it - a few simple steps and you will get a newly earned battery.

If this method did not work, and you are sure that the laptop battery is connected correctly, but is not charging, we have to upset you - the problem is unlikely to be related to the operating system and software. Most likely, you will not be able to do without buying a new battery.
