Computer stuck at 0% remaining with AC Adapter plugged in

[ChromaticCypher]

This laptop is stuck at "0% remaining" when plugged in with the charger. Once unplugged, it immediately loses all power and shuts off.

Upon restarting there also appeared a CMOS 502 Error code.

I have uninstalled and reinstalled battery drivers

Updated Windows as far as I could because there are some that are blocked for me to install because my battery percentage is at 0%

I have reinstalled Windows 11

I did a recovery on the BIOS and for one restart there was an CMOS 500 Error code and then went back to giving me 502

This all started when I just wanted to check on the battery because of the 0% issue but now there's this additional CMOS error codes being thrown. Should I just get the battery replaced and try to go somewhere to get the CMOS fixed or is there anything else I can do.

You can replace it yourself if you have the confidence or have it done at a laptop shop by a qualified technician.

Thank you for the help. I just wanted to make sure I covered all of my bases before changing the battery.

Edit: What about the CMOS error codes it threw upon a restart? Are those related to the end of the battery's lifespan?

[Huffer]

Yes. The main battery also acts as the RTC/CMOS battery so every time the laptop shuts down, the BIOS settings are lost when there is a dead battery so you get error codes on reboot. Replacing the battery will take care of that.

Okay, thank you for the clarification.
