Random sudden shutdown issue
I've got a random shutdown issue affecting my MacBook pro.
I've had the graphics processor issue in the past and the apple shop replaced my logic board. I've also replaced the battery and maxed the memory to 3gb. Over the past year my MacBook pro has begun to randomly suddenly shut down. I've tried to diagnose it myself, memory passes all tests, logs do not show anything, the apple tests you can run at bootup all pass, temperatures look correct, fan speed looks and sounds correct.
My suspicion is a temperature sensor problem but I'm not sure.
Sometimes when turning on after shutdown the laptop will turn off again after about 10 seconds.
