Won't charge, but works on battery
I had a bit of an incident a few weeks ago where 2 of my computers died at the same time. I suspect a power surge but not entirely sure, since I was also tinkering with a small development board that was attached to my desktop at the time. The desktop (PC) had it's motherboard fried (and replaced by now) - mentioning it for context.
The MacBook Pro had turned off. I had then tried turning it on, and it turned on for a second or so then shut itself down. I tried turning it on again, this time it worked, with all the date/time reset, but otherwise working well. That's when I noticed the battery is not being charged. The computer was running fine for a few hours on battery power only. I initially thought it's just the MagSafe power adapter so I went ahead and bought a new one. When the new one wouldn't charge either, I took it in for repairs. The shop said it's either the motherboard or the IO board that's fried, that they tried replacing a fuse, but it didn't work. They also said that since my Early 2011 MacBook Pro 15" is now in "vintage mode", they couldn't get official parts from Apple anymore.
Does anyone know if just replacing the charging board would work, or does it sound like the motherboard is gone too? I'm happy to disassemble and post pics, here's one that just shows the relevant area close to the charging port.
Thanks in advance for any tips & suggestions!
