What should I do if the battery on the laptop is not detected?

Sometimes the user has to deal with a message that the battery on the laptop is not detected. Often such a notification leads to panic, because it is the battery that provides mobility of the device, and even if there is an outlet nearby, it is not always possible to use it - an unstable electrical network will simply disable the laptop. So what should I do?

The reasons for the error

It happens that the battery is installed in the laptop correctly or it was not touched at all, but on the taskbar the battery icon is crossed with a red cross, and the laptop writes: "the battery is not detected."

The main reasons for this error can be three types of faults:

1. Non-working motherboard.
2. Worn battery.
3. Incorrect battery connection.

To avoid wear and tear, it is recommended that you always have a spare battery on hand. If after the replacement of the battery the message disappears, it means that it was in the service life. But not everyone complies with this recommendation, where the laptop owner often buys a battery after some problems appear. And sometimes even after a replacement laptop says: "The battery is not detected."

What to do?

There are several ways: reset the hardware settings, reset the BIOS and start the computer with a battery without connecting to the mains. Programs for calibration can also help.

Each of the above methods will be disassembled in detail in the following sections, but if none of them help, only the replacement of the motherboard will remain .

Reset

This action will help to clear the temporary memory of the laptop. At the subsequent start of 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 press the power button for 15 seconds to get rid of the remaining charge. After that, you can return everything back and start the laptop, then check the presence of the notification "the battery on the laptop is not detected."

If this operation has not helped, it is necessary to resort to the following item.

Zeroing of BIOS

This action will help to roll back the laptop to the factory settings, although if previously they have been changed by the user, this is undesirable, because then it will be necessary again to waste time on partial restoration of the parameters. Especially unpleasant is when the method does not help.

But if there is no other way out, you will have to sacrifice your time. To reset it, you need to enter the BIOS when you turn on the laptop (a specific key combination depends on the model) and find the partition responsible for resetting the factory settings. After confirming the operation, you need to exit the "I / O system" and wait for the OS to boot.

If the battery on the laptop is not detected as before, you can try to rebuild the BIOS, but you do not have to tackle this procedure for a beginner, otherwise the computer will completely lose efficiency.

Launching a laptop without a network connection

Try this method on any computer, but it does not always work, even if the battery is fully functional. As a rule, it's still a problem with the motherboard, so nothing happens.

But this method is recommended in the case when the battery is not detected on the laptop, HP for example. If the launch of the laptop is successful, the firm's experts advise that the operating system be reinstalled - often this action helps to resume the correct operation of the equipment.

No battery found

Those who have not benefited from the above advice, there remains only a direct road to the service. However, if you do not have a spare battery at hand, it is worth checking the battery for dirt 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 detected on the laptop"? It's quite simple: the laptop's 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 been subjected to any changes, there is no doubt about the cause of the failure.

Other problems

Sometimes an icon of an over-stressed battery appears on a PC running Windows 7, but this does not mean that the battery on the laptop is not detected. Most often, the OS in this case requires a replacement battery, because it does not work correctly - does not hold a charge, its real operating time no longer matches 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 there is no need to panic when it appears - unless the laptop model is so outdated that the batteries are no longer being released to it.

The remaining faults with the battery are usually solved in a similar way. If the replacement of the battery does not help , then it is necessary to check the motherboard with the subsequent installation of new equipment or components. In the event that the laptop does not turn on even with the power supply, first, you should try starting 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 its connection to the motherboard is carried out not directly, but through wires, so it is freely disconnected from it.
