Restart Your Laptop: Sometimes, a simple restart can resolve temporary glitches.
Check Power Settings: Make sure you are using the correct power settings. Sometimes, power-saving modes can limit battery charging. Go to your power options and ensure they are set to allow charging.
Unplug and Plug Back In: Disconnect the charger, then plug it back in to see if the battery percentage changes.
Calibration: Battery calibration may help in some cases. To calibrate your battery:
Fully charge your laptop to 100%.
Use the laptop until it completely drains (shuts down).
Leave it off for a few hours, then charge it back to 100% without interruption.
Battery Health Check: Check the health of your battery. Many systems have built-in diagnostic tools to assess battery health. Generally, you can find this in the BIOS or through a system report in your operating system
