What's wrong with the computer battery that won't charge?

The reason why the computer battery cannot be charged may be a power adapter problem, battery problem, charging line problem, power management setting problem, BIOS setting problem or software problem, etc. Detailed introduction: 1. Power adapter problem. When the computer is charging, the power adapter is responsible for converting AC power into DC power to supply the computer. If the power adapter is damaged or malfunctions, the battery may not be charged. 2. Battery problem. The computer battery may be aged or damaged. Or internal failure prevents charging. If the battery is damaged, it may need to be replaced with a new one; 3. Charging line problems, etc.

The failure of the computer battery to charge may be caused by many reasons. Here are some common possible causes and solutions.

1. Power adapter problem: When the computer is charging, the power adapter is responsible for converting AC power into DC power to supply power to the computer. If the power adapter is damaged or malfunctions, the battery may not be charged.

Solution: First, check whether the power adapter is plugged into the power outlet and connected to the computer. Make sure the power adapter's connection port is not loose or damaged. Try testing with another working power adapter to determine if the issue is with the adapter.

2. Battery problem: The computer battery may be unable to charge due to aging, damage, or internal failure. If the battery is damaged, it may need to be replaced with a new one.

Solution: Remove the battery from the computer and check whether the battery connection interface is clean and not damaged. If the battery has a removable design, try re-inserting the battery. If the battery still won't charge, it may need to be replaced with a new one.

3. Charging line problem: When the computer is charging, the charging line connects the power adapter to the battery. If the charging line is damaged or poorly connected, the battery may not be charged.

Solution: Check the charging line for damage or loose connections. Make sure the plug and connector of the charging cable are not damaged. Try testing with another charging line that is working properly to determine if the problem is with the wiring.

4. Power management settings problem: The computer's power management settings may affect battery charging. If the settings are incorrect, the battery may not charge.

Workaround: In the operating system, open the power management settings and check the power plan and battery options. Make sure the power plan is set to a mode appropriate for charging your battery, such as Balanced or High Performance. Make sure the charging threshold in the battery options is set correctly and does not limit battery charging.

5. BIOS setting issues: BIOS is the computer’s basic input and output system, which controls the computer’s hardware and system settings. Wrong BIOS settings may prevent the battery from charging.

Solution: Press the corresponding key (such as F2, Delete key, etc.) when booting to enter the BIOS setting interface. Check the power options and battery settings to make sure the settings are correct and allow the battery to charge.

6. Software issues: Some software may interfere with battery charging, such as battery management software or third-party applications.

Solution: Close or uninstall software that may interfere with battery charging. You can try starting your computer in safe mode to rule out the possibility of software interference.

It should be noted that the above solutions are only common solutions in general situations. The specific situation may vary depending on the device, operating system and battery model. If the above methods do not solve the problem, it is recommended to consult the computer manufacturer's technical support department for more detailed help and support.
