I'll bet you any shop will charge $200 just to look at it.

Okay, I have another way to ask the question.

Suppose I man up and take the darned thing apart. It's been on my list of projects for a while, but it's been low on the list because of the obvious frustration factor. I hate plumbing but at least I can cut a hole in the wall and replace drywall later if I really have to.

And suppose it doesn't work. I get it all back together, but something's fried in the AC power circuit in the process

It would be nice to have a backup plan, run some DC in through the battery connector. It's my daughter's old school laptop, and I seem to remember the battery wasn't holding much charge anyway.

It probably isn't as simple as just putting jolts on V and Gnd, right? The laptop probably has some circuitry to check battery state before turning on?

I've done a bunch of googling and not found anyone who's succeeded at powering the laptop through the battery port. (but also a bunch of people who tried repairing the jack and couldn't get it out without ruining the board)


I don't know. The batteries have several pins, I'm not sure what they
all do. If I found two pins that measured 12.6 volts between them, and
ONLY TWO PINS, I would feel comfortable feeding 12.6 volts into the
mates on the laptop. I'm not confident you will only find only two pins
on the battery that have voltage.
If I had it and the battery was not good, I'd tear it apart and see
what pins were the correct ones. Might even be able to do that non
destructively.
Good Luck, Mikek
