Sometimes the user has to deal with the message that the battery on the laptop is not detected. Often such a notification leads to panic, because it is the battery that ensures the mobility of the device, and even if there is an outlet nearby, it is not always possible to use it - an unstable electric network will simply disable the laptop. So what to do?
Reasons for the error
It happens that the battery is installed in the laptop correctly or it wasn’t touched at all, but on the taskbar the battery icon is crossed out with a red cross, and the laptop says: “battery not detected”.
The main causes of this error can be three types of malfunctions:
- Inoperative motherboard.
- Battery wear.
- Incorrect battery connection.
To avoid wear, it is recommended that you always have a spare battery on hand. If the message disappears after replacing the battery, it means that it was the term of operation. But not everyone follows this recommendation, where more often the owner of a laptop buys a battery after certain problems have arisen. And sometimes, even after replacing the laptop, it says: "no battery detected."
What to do?
There are several ways: resetting the hardware settings, resetting the BIOS and starting the computer with the battery without connecting to the mains. Calibration programs may also help.
Each of the above methods will be discussed in detail in the following sections, however, if none of them helps, there will only be a replacement for the motherboard.
Reset
This action will help clear the temporary memory of the laptop. The next time you start the laptop, the OS will conduct a full check of the equipment, including the battery. To reset the settings, you need to disconnect the computer from the power supply, remove the battery and hold the power button for 15 seconds to get rid of the residual charge. After that, it will be possible to return everything back and start the laptop, in order to then check for the presence of the notification “no battery was found on the laptop”.
If this operation does not help, you should resort to the next paragraph.
BIOS reset
This action will help to reset the laptop to the factory settings, although if they were previously changed by the user, this is undesirable, since then you will have to spend time again on partial restoration of the parameters. It is especially unpleasant when the method does not help.
But if there is no other way, you have to sacrifice your time. To reset, you will need to enter the BIOS when the laptop is turned on (the specific key combination depends on the model) and find the section responsible for resetting to factory settings. After confirming the operation, you need to exit the "I / O system" and wait for the OS to load.
If the battery on the laptop is still not detected, you can try to flash the BIOS, but the beginner should not take up this procedure, otherwise the computer will completely lose its working capacity.
Starting a laptop without connecting to a network
You can try this method on any computer, but it will not always work, even if the battery is fully functional. As a rule, these are still problems with the motherboard, so nothing happens.
But this method is recommended when the battery is not found on a laptop, HP for example. If the launch of the laptop is successful, the company experts advise you to reinstall the operating system - often this action helps to resume the correct operation of the equipment.
Battery not detected
Those who are not helped by the above tips, there is only a direct road to the service. However, if there is no spare battery at hand, it is worth checking the battery for contamination and oxidation of the contacts - perhaps this is what caused the malfunction.
Sometimes the owners of the gadget wonder what it means "the battery is not found on the laptop." Everything is quite simple: the laptop motherboard does not see the battery, because there is no proper connection of the contacts. Therefore, if the battery is completely new, and the OS has not undergone any changes, there is no doubt about the cause of the malfunction.
Other issues
Sometimes a crossed-out battery icon appears on a Windows 7 PC, but this does not mean that the battery is not detected on the laptop. Most often, the OS in this case requires replacing the battery, since it does not work correctly - it does not hold a charge, its real operating time no longer corresponds to the displayed indicators, or the laptop does not turn on at all without connecting to the network.
This problem is solved in 95% of cases by replacing the battery, and you should not panic when it appears - unless the laptop model is so old that the batteries are no longer available.
Other battery failures are usually resolved in a similar way. If replacing the battery does not help , then you need to check the motherboard with the subsequent installation of new equipment or components. In the case when the laptop does not turn on even with the power supply, first of all, you should try to start the PC from another charger. If the situation does not change, the connector may be defective. Sometimes it can be replaced on its own, because in some models it is not connected directly to the motherboard, but through wires, so it is freely disconnected from it.
