Water Damage Repair and Question

Hi,

I spilled water on my macbook, which is currently upside down being dried. After the spill, it automatically shut down and now I'm planning on fixing it myself since I can't afford having it repaired. I'm planning on diassembling it and cleaning every trace of corrosion with 99% alcohol, but here are my questions (and please bear in mind that I have almost 0 knowledge of technology):

· I've read that it's important to replace the thermal paste, but I'm a little confused as to where and for what I need to replace it; for which piece exactly? And will any brand do?

· A technician told me the circuit was fried and that the main damage is the corrosion; does that mean that fried = corrosion (same problem), or is a fried circuit another distinct problem from corrosion?

· Are the screws inside the laptop (on the motherboard) the same as the ones on the lower case? I've ordered a 5 pnts screw online (the small one that I have right now couldn't unscrew the case), but I want to make sure I won't be needing any other tools.

· Is there a possibility that my laptop still won't be functionning after those steps?

Thank you! Also, any additional piece of advice is welcomed

If it shut down on its own, you likely fried something. Doesn't sound good ;-{

I would get the full tool kit IFIXIT offers (small set) that way you'll have the basics. You'll still need a antistatic mat if you take the logic board out and a wrist strap to bond your system to sound to prevent ESD damage.

First thing I would do here is disconnect the battery ASAP! Bottled & tap water have salts and other minerals which will corrode things as well as cause a short which can damaged delicate chips.

Thermal paste is used to bond the heat sink to the CPU & GPU chips to drain the heat away. If you take the heat sinks off you'll need to clean all of the old paste and apply a fresh coat.

But for now let just see what is visibly damaged. In no case should you charge your battery or restart you system until you clean the water and any corrosion out.

Water damaged systems are alway tricky. If you didn't get to much in and you acted quickly you might be lucky. Its also possible the system will require a fair amount of parts to bring it back to life.

Before you go to deep here replacing parts look on eBay for a similar system. Does it make sense just swapping out the HD and calling it a day with a working system? It maybe cheaper and less risk.
