7]Calibrate laptop battery

This is one of the best options if the battery power suddenly drops to 0%. Windows estimates remaining battery time based solely on your laptop's usage and assumes you will continue to use it the same way. As laptop usage changes, estimates will change accordingly. Although this estimate is almost accurate, if you see a sudden drop in battery time and percentage while using your laptop, you can calibrate your laptop battery manually.

We also recommend that you check for BIOS updates. Before updating BIOS, you need to check the version of BIOS from System Information or Command Prompt. If an update is available, install it. You can download the latest BIOS updates from the computer manufacturer's official website.

If none of the solutions work for you, then it's possible that your battery is faulty. In this case we recommend that you replace the battery. Before making any repairs or replacements, make sure to back up important files to avoid data loss. Get professional help to confirm if your battery is faulty.
