MBP 17 Early 2011, Battery Fan problem after liquid spill

by speedbump21 / December 5, 2012 5:46 PM PST

Hello all,

I spilled a small amount of liquid on my Macbook Pro 17" 2011 Early edition. I flipped it over as soon as possible and turned it off by constantly pressing on on/off button.

The liquid spill was on the left side where the MagSafe and I/O board is. Opened the panel at the bottom, and left it on sideways overnight. Also used a hair dryer fan to remove any moist left the next morning.

Then turned it on but nothing, it was dead. I took it to Apple Store and they told me there's corrosion and they told me they can fix it for flat $1,240. I can not afford that right now, so I picked it up. Left the laptop sat like that for 3 more days and trying to figure out what to do in the mean time. I did not try to turn it on nor plugged. I ordered iFixit tools and was planning to clean the corrosion whatnot myself, as if I knew anything. But did not do it yet.

Last night I eventually wanted to try again, and to my delight it turned on. It booted up, loaded the system and brought up all the apps where I left off. I am really happy.

Unfortunately it has become very clear that there's still some damage. Firstly it says there's no battery, although battery connection and the battery was not wet at all. And the fans works at full speed as soon as I turn the laptop on.

What would you suggest?

Thanks for any help.

Yes, that's it. GET YOUR STUFF SAFE on a few backup devices. Don't fall for the usual trap of a single copy on some external.

As to repair the current boards do not lend themselves to repair. I don't want to upset folk but if they ask that means they don't do board repair. It's not a skill you can acquire in a discussion forum. You do this at some job and over time you learn what to look for under a high power microscope and use tools such as fine tip solder irons and more.

The costs are so high that replacing boards is cheaper.

I have experience rebuilding circuit boards under microscopes. With modern electronics if you have corrosion, attempting to clean off the corrosion is usually futile. Back up your data and back up frequently. Save your money and be prepared to either buy a new computer or pay the repair price.

I did disassemble the logic board to see if I can clean it. Actually there's nothing to clean, I do not see any residue of spillage or whatsoever. It was black tea, that's probably why. I will take to a nearby repair shop to get a second opinion however seems like I need to buy a new logic board.

Thanks for the replies.
