Questions regarding fixing of a liquid damaged macbook pro
 
I recently got a liquid damaged macbook pro 13 unibody a1278 at a very cheap price. I've never been a mac user ever in my life and purely a pc user. But I always like to fix electronic things and bought it because it was really really cheap thinking I could fix it myself.

I'm guessing the damage is about 1-2 months old. Not sure what kind of liquid damaged it. Upon receiving it from the looks of it. I cannot see any type of liquid residue on the surface itself and is in mint condition. I opened up the macbook to check the logic board. I can see that there's white residue(didn't smell like juice/coffee..so I'm guessing its water) along circuit connections and it doesn't look like it has gone into other areas(superdrive, HDD, battery) of the macbook. So I've inquired and visited one local repair services. One guy is apple certified and other is not.

They said:
1. 80% of the logic board can be recovered but no guarantees. $100-150
2. Replace the logic board. $500-800

My questions:
1. If I purchase the A1278 logic board from ifixit.com and replace it... will it alone help this problem to restart the macbook?
2. Can I take out the HDD and put it in my dell laptop to see if the HDD still works?
3. Will I have to replace the RAM and processor because of liquid damage?
4. The HDD.. if I do take it out and format it..it works fine can I put it back into the macbook and reinstall osx?
5. The keyboard doesn't seem to have any liquid residue either..but its actually the only logical place for any liquid to enter from the top that is.
6. Lastly...why is the type of liquid important in liquid damages? ex: is water damage better than juices/coffee damage?

Who knows? Sadly liquid + computer = disaster as a rule of thumb with corrosion and all the rest of that ugliness.

There is no 'better' damage, but water sure is better than tea, coffee, wine and pet urine. Have a look at this link:-

Hey harry: Pet urine? Yechh...:Angry-Tongue:

All kidding aside, you're right. There is no "good" liquid spill on electronic equipment. It's all bad. I guess with a little bit of luck he could replace that logic board and be OK. But who knows where else whatever spilled on the machine got into and what troubles it will cause later on?

Regards.

that white residue is likely corrosion.

Hard to say. Many times liquid will run where you'd least expect it.

Sure, I'd recommend using a USB to SATA adapter. You can purchase one at any good computer store for about $20. Be aware that although you should be able to see the drive is Disk Management, Windows will not able able to mount the Mac partition without the help of 3rd party software.

3. Will I have to replace the RAM and processor because of liquid damage?
Not unless there is damage around the RAM. The processor is soldered fast to the system board and will be replaced with the board.

Yes.

It's easy to clean the key caps. It's hard to clean beneath them. It might look brand new and still not work.

Really, it isn't. Liquids and electronics don't mix, period.

Thanks for the answers cwa107.

Yea I tried the USB-SATA adapter in my external HDD enclosure. Seems to be working fine. It installed the drivers but cant actually see whats in the HDD. Im going to install macdrive 8 to see if its going to work.

I guess the only way I can check is to have a another MBP in hand to swap parts and test them. Better off taking it to a shop.

Unless someone in Toronto would like to help me out with this project.
