A few days ago, some coffee went on my MBA(4,2).
I immediately took it down, unplugged it from the magsafe, and started to open it to dry it the faster I was able to.
After a few days in rice and putting the piece back together I booted it. It was working quite well given what happened but now the fan are going full speed, even after SMC & NVRAM reset. The SMC Fan Controller can see the speed of the fan (6500rpm) and I can't change it. Which is annoying.
But what is way more annoying is that now my trackpad & keyboard are dead. Well, almost dead. Because I can still boot my mac. By the way, the keyboard backlight is still working as usual, enabled when a key is pressed (just the power key) and disabled after 10 secs)
How can I fix theses two issues (preferably with a lot of time and the less money as possible)?
(ps: I didn't find better tags, please, feel free to fix this :) )
