18 hours ago comment added ReflectYourCharacter The suggested calibration cycle plus a BIOS reset and a test with a live OS is exactly the right approach to clearly distinguish between a software and a hardware issue. So step 1 can effectively be skipped.
18 hours ago comment added ReflectYourCharacter @terdon Yes, if the laptop shuts down immediately as soon as the power adapter is unplugged, the battery is effectively not supplying any power. This means the displayed 60% is very likely incorrect. The most likely cause is therefore that the battery is defective or internally disabled, e.g. due to a protection circuit, cell damage, etc. I would say with 99% certainty that this is a battery failure, but strange is since this behavior appeared after the upgrade to Linux Mint 22.3
19 hours ago comment added terdon If the OP's machine shuts down immediately as soon as they disconnect the battery, doesn't that suggest that the battery is already at 0%?
