The battery lasts about a mont in that laptop and gets worse quickly over time when not regularly charged.
I’m not sure if the short runtime is caused by the design-decision of using a rechargeable battery or a big power-draw from it.
For me this is also the first laptop that ever had an issue like that. Even my decade old thinkpad is still on its first CMOS battery.
A while ago I was thinking about doing something similar, but tearing down a working one seemed wastwful. I also couldn’t find a motherboard on its own (neither trough the repair program nor elswhere), so I shelved the idea.
