I have some non-trivial problem. If my notebook stands on solid surface everything is fine, but if I put it on my knees (for example, it could be a book too) or just push the center of the bottom cover, the CPU usage immediately grows to 100%. It also causes issues with the WiFi.
I have MacBook Pro mid 2010, which I manually upgraded to an SSD (optibay) + 8Gb DDR. I recently disassembled it and cleaned it, but the problem came yesterday. I tried to manually push some points on motherboard but failed to reproduce the problem, it only occurs when pushing the bottom cover.
In Activity Monitor, kernel_task is using greater than 170% CPU. There are no warnings or errors in logs during this problem.
Has anyone else seen this? What can I do (other than going to a service center)? What kind of problem could it be?
I've done messy solution - place the steel coin between the bottom cap and the processor's fan. Now the bottom cap did not contact the cooler and everything's fine.
