Step 1: Reset the CMOS
Start by resetting the CMOS on your laptop. This can often resolve issues caused by power surges by restoring BIOS settings to default. Open your laptop, remove the CMOS battery, wait a few moments, and then insert it again.

Pro Tip: Create a system restore point before making changes in Device Manager to preserve your settings.
Step 5: Calibrate the Battery
Calibrating your laptop’s battery can help recalibrate the charging system. Follow manufacturer-specific instructions for performing a battery calibration.
Step 6: Seek Professional Assistance
If your troubleshooting efforts have not yielded results, consider reaching out to a professional technician for further diagnosis and repair options.
