notestar NP-743 CMOS battery leaked, but it needs to be there for the laptop to POST, also no working boot drive
I removed the leaking battery and cleaned the leakage a little, but that caused it to not POST (screen off, HDD spinning), it works with AAs connected to it, how do I fix it in a more permanent way? solder the old battery back on? make AA/AAA work?
FDD has torn spindle belt, any way to get one? should I bother? it is around 225mm long
HDD autodetects, but there is “HDD controller failure” on boot when the HDD is configured, regardless of whether it is connected (but not when not configured), HDD does read and work when connected using an IDE to SATA adapater to a modern PC
