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.

Another obvious reason to have a current leaking is when batteries have leaked...I had this issue in so many different equipment types that I forgot to mention initially.
When this is the case, usually we can see some fluctuation in the current readings.
And after a few weeks/months when the battery electrolytes finish reacting with the PCB copper traces, usually the machine stops working due to electrical isolation caused by the final chemical reactions.

But of course we need to open the machine to find out.
Good luck with your new acquisition.

Cheers,
