HP-50G Excessive Battery Drain / Fix?

[HrastProgrammer]

Thanks for the additional info!

I probably won't do much about it these days because I have a lot of other things to do. Right now, it was important just to confirm the problem. But I definitely plan to open it and try to fix it someday.

Yes, it works flawlessly, all tests passed, no crashes, etc. Except battery drainage everything else is fine.
