My MacBook Pro 13-inch 2.4 GHZ (Mid 2010) starts up normally but after approximately one minute the fan accelerates and the system slows down dramatically. The CPU load goes up to 99% as I see it on Activity Monitor. The laptop is running without battery as it suffered a water spill some months ago. There is no virus and no other process is using large amounts of memory.
The problem was thought to be linked to a DC-in board that I replaced after the water damage. The DC-in board was working fine and the input voltage is approximately 16v as seen on a voltimeter. Apple Hardware Test gives me this code: 4SNS/1/1C0000008:TN1D--124
- How can I check what part of the logic board is what sensor?
- If there is a faulty temperature sensor on the logic board how can I find it and replace it using the above code?
