Chosen Solution
I had to get the fans replaced before had the same problem with them recently whilst changing them the wi fi chips cables touched the main board and started to smoke the machine pictures are where I assume the smoke came from is this repairable without buying a new motherboard? also during repair the battery cables snapped
it had R005 or P005
It’s hard to tell from the pictures. But both the resistor and the capacitor in this area look a bit questionable? I am more concerned that it looks like the solder around that resistor seems like it got pretty warm. The capacitor could be normal, but could also just be thermal paste schmoo. If there was smoke, generally there will be evidence. If it came from the WiFi antennas touching the board, I would say look in the areas where they connect. See if you can get a closer picture of that area.
As for repairable, that depends. It’s possible if you have soldering equipment/knowhow. In fact, if it IS the capacitor, or the resistor, both of those are large enough that you might get away with doing it on your own. But it’s hard to know if those are the only issue. Depends on the specifics of what happened. If by battery cable snapped off, you mean a connector on the board snapped off? that’s probably also repairable by someone with soldering know how. A new connector would neen to be soldered on. Likely the cost would be far less than replacing the whole board, you would just need to find someone who does board level repair. Was the battery plugged in when you were doing the repair?
NEVER, open a laptop without removing all power from it including the battery. If you must power it up when open to troubleshoot it, DON’T disconnect things with the power connected. Power OFF does not help. An expensive lesson learned. The hard part about repairing the MB is determining what parts are bad and what the actual part is. If some very small SMD or very large 100 pin devices are bad, it is time for a new computer.
I think you already know the answer here. The shop is quoting you a cost to replace the motherboard. I’m guessing that motherboard is pretty expensive, hence the high cost. It looks like the cap is probably fine, but the big problem is the area on the right side of the resistor where the PCB mask has burnt off and the bare metal is exposed. This is indicative of likely shorting between PCB layers. Long story short, please don’t take this the wrong way, but if you’re someone who tries to work on a laptop without disconnecting the battery first, you’re not going to be able to fix this. It’s likely that someone with enough time, skill, and monetary motivation could fix it, but I’d expect them to charge you at least $500 to do it properly. I wouldn’t bother taking on a job like this, because who knows what else you could have damaged when you took it apart. Sorry, I truly do not intend to sound negative but unfortunately there’s no good news to tell you in this situation.
