1. Check the power connection
The first step before dealing with any software or hardware issues is to make sure that the power supply is properly connected.
1. Check the power adapter: Make sure the power adapter plug and socket are connected firmly. Inspect the adapter for signs of damage or wear and replace the adapter if necessary.
2. Check the power cord: Make sure the power cord is not broken, bent or broken, and try to use the spare power cord for testing.
3. Check the battery interface: confirm that there is no dust or foreign matter on the interface between the battery and the computer. Clean the interface to make sure it has good contact.
2. Adjust the power settings
Sometimes system settings can cause charging issues. The following steps can help check and adjust the power settings:
1. Check the power plan: Open the "Control Panel" and select "Power Options". Check the currently selected power plan to make sure it's not set to energy saving mode, and you can choose Balanced or High Performance mode.
2. Reset the power plan: Select "Change plan settings" in "Power Options" and select "Restore default settings".
3. BIOS settings: enter BIOS settings (press DEL, F2, etc. keys when booting). Check the power-related settings and make sure the "Battery Charging" option is enabled. Reset the BIOS to default, save and exit.
3. Update the driver
Driver issues may cause the battery to charge abnormally. You can update your drivers in the following ways:
1. Device Manager Update:
Right-click This PC, select Manage, and open Device Manager. Find Battery, right-click Microsoft ACPI-Compliant Control Method Battery, and select Update Driver.
2. Download from the manufacturer's website: Visit the computer manufacturer's official website to download and install the latest battery management and power management drivers.
Fourth, carry out hardware diagnosis
Hardware issues are a common cause of a power supply that is plugged in but not charged. Here are some hardware diagnostic steps:
1. Check the health status of the battery:
Open Settings, select System, and then select Power & Sleep. Check the battery health status to check if the battery life is exhausted. If the battery health status shows bad, consider replacing the battery.
2. Battery and power adapter test:
1) Turn off the computer and unplug the battery and power adapter. Press and hold the power button for 30 seconds to discharge the residual charge.
2) Plug in the power adapter, do not install the battery, and test whether it is normal when powered on. If the computer starts up normally, there may be a problem with the battery and needs to be replaced.
3. Replace the battery or power adapter: Test with another compatible power adapter or battery to confirm which part is the problem.
5. Software troubleshooting
Sometimes software conflicts or system errors can also cause charging issues. The following methods can help troubleshoot the software:
1. Uninstall the battery driver:

If you have recently installed new software or a system update, you can try to restore the system to its previous normal state. Open the Control Panel, select Recovery, and then select Open System Restore, and follow the prompts to complete the restore.
6. Reset the power management settings
Sometimes, the power management settings may need to be reset to resolve the charging issue. To reset power management settings:
Open a command prompt (run as administrator), enter the following command and press enter:
powercfg -restoredefaultschemes
Restart your computer and check if the charging issue is resolved.
