Instant power loss as soon as unplugged
No recent drops or bumps that I can recall
SteamOS reports 100% battery and healthy
Opened it up and reseated battery connections, everything looks ok but no dice
Claude guesses it’s still a failed battery but don’t want to drop $130 on a guess, any other suggestions before I buy a new battery?
Unfortunately a lot of free out-of-warranty repairs just come down to what support tech you ended up talking to.
