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?
Have you measured voltage across the terminals?
No, honestly I don’t know how to do that
Try recalibrating the battery
He said instant power loss when he unplugs it, will be hard to recalibrate the battery like that
Multimeter, as another poster said. Be careful not to short the terminals. I do recommend you ask someone for guidance who have some electronics experience, lithium batteries can be a little dangerous if you are very inexperienced… And even if you have some experience.
