My MacBook Pro Wont Power Up

Cat spilled water on it. Opened it up, dried it all out, no visible shorts, or bad smells on board, however, laptop wont boot up. Also, power adapter (green / yellow) light doesnt light when attached. Same power adaptor will function properly when attached to alternate MBP. Where should I look to start replacing parts?

If you have had water spilled on it less than a day, Please consider unplugging it and your battery for two to three full days before trying to do anything with it. Drying out on its own is often all it takes. But remove power. Had one in two weeks ago that had water on it and after three days it started running again and all has been fine.

If still no light and you can verify the power pack is ok then one of the first parts would be:

MacBook Pro 15" (Model A1150) Left I/O Board But verify the part first when ordering it, Making sure it is right computer.

It has the power port on it. But let us know how long it has been since water was spilled so we can also think on it more.

With no light at the DC In port, that's the place to start. But first charge the battery on the other machine. Reinsert it and try to start. Let us know what happened.

Thanks for your reply. So, fully charged battery, still same results. Thinking I should replace logic board, but I am hoping it might be the IO board instead? Any way to tell?

I agree, sounds like the DC-in sound board. But do you know which side of the machine the water spilled on? If it's on the left, and on the DC-in/sound board itself, that increases the chances that replacing it will fix the machine, and if it's on the right, the chances that it's the logic board itself increase. Often you can spot physical evidence of the liquid damage on the components, and that will give you hints, so taking the machine apart might be worthwhile. Also, if there is visible corrosion/residue inside which can be cleaned up with q-tips dipped in rubbing alcohol, that act in of itself sometimes brings the machine back to life, so I'd give that a shot as well before ordering parts.

There's always a risk in replacing the DC-in/sound board that you'll find out it's actually the logic board, but you have a nice enough machine that it's worth the risk.

It was on the left hand side, so I guess I will go ahead and replace the DC IO board. In terms of board replacement, my understanding is essentially you the the DC IO board and the logic board - yes?

You should only need to replace the i/o board. Here's the guide:

Ok, so I replaced the left IO board. When I took it out, it was definately corroded - very bad, but it doesn't appear that the logic board was damaged. Replaced completely, however, still same symptoms. No green or amber light on the power supply, I have two, they both work, but not on this MPB. Any other ideas?

Sorry to hear that. Here's a link to a guy on eBay who repairs Pro logic boards for $245. He's currently working on one of mine, and Lemerise and others have great things to say about his work. It probably makes more sense to go with something like this than spending $500 on a board, etc.

Well, I went and bought a new logic board and same issue. So, I have replaced the DC IO board and the logic board. New hard disk, new battery and new power supply. Any other ideas on what this could be? Only thing I havent replaced is the keyboard. That of course is not going to display the symptoms I am seeing I dont think though. Again, no green or amber charge light on the power supply and no fan bump, nothing. Any other ideas before I go kick myself repeatedly for dropping over 600 on this laptop?
