Battery keep draining while battery status showing 100%

Question

Im using my laptop plugged in all the time. The battery status shows that it is full charged. Sometimes, the "Your laptop ran out of battery" popped up and the laptop shut down by itself immediately. I should waited about 15 mins to start the computer again.

Please advise!

Hello Jorsua,

Thank you for posting question on Microsoft Windows Forum!

Based on the issue description, the suggestion here is to run a Battery Health Report by running this command powercfg /batteryreport in administrative mode. It will give you a file path (usually C:\Windows\System32\battery-report.html). Open that file in your browser to check if the Full Charge Capacity is significantly lower (e.g., 50% of the Design Capacity), your battery is physically worn out and might need replacement.

Other troubleshooting suggestion is to try another charger or outlet. A bad adapter can let the battery appear full while not actually powering the system. Also, try to calibrate the battery. Fully charge, then let it discharge to shutdown, then fully charge again. This might fix reporting errors if the battery is otherwise healthy.

Sometimes the driver that communicates between the battery and Windows gets "stuck". It is worth considering to reset the battery drivers. Right-click the Start button > Device Manager. Expand Batteries. Right-click Microsoft ACPI-Compliant Control Method Battery and select Uninstall device. Restart your computer.
