Spilled water on Macbook Pro a month ago

[eosannn]

About a month ago, I accidentally spilled water on my MBP. As it happened really quickly, I stupidly assumed that no water entered the insides of the MBP and left it be (which I now realised was a terrible mistake as I should have turned it off and tried to dry it)!

After the incident, I noticed 3 problems:
(1) Fan running really quickly,
(2) MBP freezes sometimes (very lagged), and
(3) Mouse cursor moves and open apps on its own.

Being the computer noob I am I did not suspect that these symptoms were related to the water spill until I have sent my computer for diagnostic testing at an Macbook Repair Centre. I was just contacted that they will have to fix my water spilled motherboard. But the repair costs are so high that my parents are unwilling to pay for it. I'm looking for a cheaper workaround now. Is it possible to fix the damage myself?

Even though all hope for my computer is probably really low by now, I will really appreciate all opinions and help given! Thank you so much!!!!?

I'm sorry to hear about the water damage to your MBP but as you now realize yourself, time is of the essence and it is really important to shut down, remove the battery and repair as soon as possible after liquid enters a Mac (or any other electronic device). The longer the motherboard is exposed to water, the greater the chance of corrosion.

Some will say it is possible to disassemble a water-damaged machine by yourself and repair corrosion using a toothbrush and alcohol. The problem is, water can get into places you can't reach with a brush, like under chips. The reason it is such an expensive repair is because it involves completely disassembling the machine to remove all water, clean corrosion and replace damaged components like damaged capacitors as well as repairing/resoldering with a microscope.

Depending on how extensive the damage is, the logic board may be irreparable and need to be replaced.

I'm sorry to tell you this but I think professional repair is your only real option.

I hope it works out for you.
