Fan died, now trackpad and keyboard won't work
Hi, I left my macbook air in my desk and when I returned, I couldn't use the trackpad and keyboard anymore. Since it was left untouched, there was no mecanical trauma (I live alone). Simply no response from keyboard and trackpad, but USB external ones, work. I did the apple hardware test and I got
I searched for this error and apparently it indicates problems with the fan. I verified and I can't indeed hear or feel the fan working, so it might be dead. Is it possible that the fan died and the macbook overheated to a point in that the keyboard/trackpad connections got broke? Keyboard backlight stills on... Since it didn't occur in the middle of my usage, but just when I opened the macbook again, there's no reason for the keyboard to stop working by overheating.
My macbook air is from 2011, 13" and I don't have apple care, and here in Brazil the only two apple stores are too far. I can buy the fan and change it myself, but what about the keyboard? And why didn't the keyboardtrackpad problems appear in the hardware test?
Could you guys help me pointing the pieces that are likely to have 'desoldered' from the mainboard? Where can I see the schematics for the keyboard and mouse?
Thank you so much!
MacBook Air, running debian 8/windows 10
UPDATE! Here are some images. I opened the macbook, it had a lot of dust. I cleaned them from the fan and it started working again! I don't have the tools to remove the battery yet, but I can't see any alterations. Can you guys see it? Should I remove the battery anyways?
PS: now debian shows 2000rpm for the fan, it didn't show anything before
PS: Images of the macbook without battery
It looks right...
I've turned it on without the battery, no keyboard and trackpad. I've verified the trackpad and keyboard and no problem in their connectors.
What more can I try?
Es esta una buena pregunta?
