Why super SLOW & Fan full speed after opening case 10.9.2?
MacBook Pro 13" Unibody Mid 2010 Dual Core 2 2.4GHz
In order to change a broken glass, I opened the case according to the guide here. (Thank you)
After I reassembled, I noticed the computer was running very slow and the fan was on all the time. However I can login and all my applications do work (though responsiveness is very poor).
At first I thought it had something to do with the clock and certificate verification (since I disconnected the battery), but after setting it correctly and rebooting, the problem didn't go away.
I don't think the wireless was able to connect to my hot spot at home, but that might just be another symptom.
I verified the disk using the Disk Utility from Finder, but that didn't reveal any problems. So I'm currently running the AHT and still waiting for that to finish (with extended tests). After 50 minutes it was approx 1/3 done, so I cancelled and ran the shorter test. It reported error:
4SNS/1/c0000008:TSOP--124 (Heat Sink, thermal sensor)
What can be done? (I can't believe it's failed because it was working fine before I disassembled.)
Cheers,
Nap
Is this a good question?
