Title:

Static noise when plugging in; won't boot

Text:

Hello. I recently purchased an untested PowerBook 5300cs; once I received it, I found there to be a large amount of corrosion from the NiMH battery. Note that the majority of the pieces of circuitry did not have much, if any, corrosion on them.
 
After a [https://www.reddit.com/r/VintageApple/comments/adonuu/powerbook_5300cs_refuses_to_boot_probably_from/|two week process] of soaking everything in vinegar and isopropanol, I plugged the laptop into the wall (with the battery removed, of course). It made a noise reminiscent of static, and showed no other signs of life. I unplugged it and replugged it; it didn’t make the static noise again, but it still wouldn’t boot. The HDD did not spin up, and the display (obviously) did not turn on.
 
I’m hoping it’s fixable, but I’m pretty sure the logic board is fried. Any help would be much appreciated. Thank you.
 


EDIT
EDIT: After leaving it unplugged for a day and trying to start it up again, it did makestarted making the static noise when being plugged inagain. Only the first few times I unplugged/repluggedcycles of unplugging/replugging it, did it make the noise, however. (Note that “the static noise” is about half a second of static coming from the speaker built into the monitor)
