Windows 10: Battery stuck at either 0% or 100%, win 11, Lenovo

Today while using my laptop unplugged, it has suddenly powered off. I did not pay attention to the battery bar at the time, but I'm pretty sure it was stuck at something around from the day before when I last used it. I plugged in my laptop but the battery seemed to be stuck at 0%. I did another reset and the battery was then at 100%. I wasn't sure what the battery was before the shut down so I went along with it. Later I continued to use my laptop unplugged and after around 2h noticed the battery to be still at 100%. The Lenovo Vantage showed my laptop as having over 4h of battery remaining;

Brightness Stuck at Either 100% or 0% in Windows 10.

This issue
has been posted about before. I am having the same issue, but have noticed that my brightness is stuck at 100% or 0%. It seems to stay wherever it was set when it rebooted. I am about to see if it stays at 50%

I have tried:

• reinstalling (deleting the driver files) the video driver.
• Setting the brightness to 0 & rebooting

Rapid Battery Drain and Fast Charging Issue on MSI Bravo 15 (Windows 11)

Hello,

Thank you for the suggestion.

I do have the MSI Dragon Center utility installed on my laptop. I checked within the app and found the Battery Calibration option. I have run the battery calibration as recommended.

However, after running the calibration, the issue persists:

1. The battery still drains from 100% to 0% in approximately 9 minutes upon startup.
   
2. The battery still charges back to 100% very quickly when plugged in.
   

Is there any other step I should try, or could this indicate a deeper hardware issue? Any further advice would be greatly appreciated.

Thank you for your assistance.
