I've read somewhere on the internet that even if someone manages to repair a CPU's pin, that it will never ever match the feel and performance of a CPU's pin that has never been touched or damaged.
And I believe this could be true...
I had to install a new CPU cooler and i when i took the pump off, the CPU came off with it. I accidently dropped the CPU and there might be thermal paste on a pin (not sure). Miraculously the CPU still works, however there is now no sign of audio output.
The microphone still works but neither...
