So for the past year my laptop was randomly shutting down, having problems when booting, getting every few days "The CMOS checksum is invalid" - CMOS Reset(502) error. Right now at this moment the laptop won't even boot up, only when i plug it in and the light appears i start it and after 2 seconds it shuts down. Last time it was properly working(yesterday), it was plugged in all the time, then suddenly the battery percentage started dropping, laptop shutted down at 20%, then after 5 minutes i could start it back and it shutted down when battery came to 0%. One or two times it booted up, logged in and after 30 seconds it shutted down, i saw that the battery was at 0%(plugged in).
