Fan Attached to heat sink in laptop not always spinning?
My laptop seemed to be overheating and shutting down an awful lot so I thought it may be down to dust building up inside the machine. I took the laptop apart and there wasn't that much, which I thought was strange. I put the laptop back together and turned it on, and after not very long it overheated and shut down again. This time when it shut down I looked at the fan that is attached to the heat sink inside the laptop and noticed it wasn't spinning. I remembered connecting it to the main board but thought it mustn't have connected properly so went in and reconnected it.
When i powered the laptop on again I checked to see if it was spinning or not, and when it turned on it span then stopped spinning. Is this always supposed to spin or will it turn itself of from time to time.
(for the record as I have been typing this it has started spinning).
