Liquid damage, Now running slow with overactive fan.

Had a water bottle next to my bed and accidentally knocked it over in the middle of the night onto my mac.

The following day I opened it up, my track-pad was over-responsive, wifi didn’t work at the time either. Wifi and trackpad are working again since I let it air out. However, the slow processing speed has not changed.

There was some corrosion noted near the track pad connecter/cable on one side, otherwise there was no other obvious signs.

The fan is over-working also present on start up.

Can anyone point me towards some resources? I am a novice with Mac repairs, however am comfortable replacing my own display for my iphone if this helps with my skill level.

Answer this question I have this problem too

Is this a good question?

Hey Matthew,

Sounds like a Sensor is damaged. This causes the Computer to think its running a lot hotter than it actually is and throttles down the CPU and runs the fans high. You can use a Sensor Checking software to see what sensor it is.

If it’s the trackpad sensor you will have to deal with prying out the battery carefully for replacement, otherwise its going to be a Motherboard repair, it shouldn’t be too big of a deal for any repair shop offering micro soldering. As long as they know what they are doing :P
