Can I fix this logic board without power?
My laptop isn’t letting me charge the battery, and as far as I can tell, that’s the only thing wrong with it (And the chargers are fine, one is even new). I don’t know anybody else with the same kind of laptop, and both my working batteries are dead now, so can’t charge them that way. Before anybody asked, yes, I’ve reset the SMC. I’ve also replaced the DC In (which definitely needed the replacing).
Looking at the logic board, it’s pretty clean (though I plan on doing a more thorough job soon) there’s no apparent damage or corrosion, everything appears to be plugged in, the only thing that really catches my eye is one spot where the dots seem a little browner than the rest (I can post pics later).
A little history, the laptop’s been having issues charging for a little while. It started with one charger when I noticed it would only charge if the computer was off. I bought a new charger and that worked for a while, but then it decided it didn’t want to charge at all, so I had to go back to only charging when it was off. Then the first charger stopped working entirely, and the battery ran out. After that, I replaced the DC In, but it still wouldn’t work. Pretty sure everything’s connected right.
I’m very much on a budget right now, but I’ve got a multimeter I’m learning to use and might know some people who can help me with soldering if that’s what it needs. Guess I’m just wondering what the problem’s most likely to be, if the browner dots are where I should be focused and how you’d fix that if so. Basically I’m still new to dealing with the logic board but I really want to save my laptop if I can.
EDIT: Pictures! (Hopefully this works right...)
Should be two halves of the logic board, plus a close up on the area with the dots that *might* be browner. The chip right next to them is labeled ‘LSI L-FW643E-2 BAN312MN NNAA8062 1131T’ if that helps at all.
Plus, the back, if that helps. Nothing that looks obviously wrong as far as I can see.
Is dit een goede vraag?

Really, at this point, I’m hoping the in-depth cleaning will fix it just because I bothered to post the question and it would be super ironic if the whole problem was it just needing better cleaning the whole time. (That and the DC In part, cause that was obviously bad)
