|The CPU fan in my Thinkpad R50e has suddenly changed habits. It used to run at max speed during POST, then turn on 5 or 10 minutes later when the CPU warmed up.|
Now, it seems to run only during POST. 5 or 10 minutes later I hear a clicking sound but the CPU fan does not turn on. I disassembled the laptop and examined the fan; there are no obstructions, and the blades turn freely. Also, there are no error messages generated.
Any suggestions appreciated.
