    My Compaq M2000 Presario fan will not work. I have even bought a new fan and it still does not work. Is there a thermal switch on the motherboard that i could use to turn on the fan. Help is much apreciated.

    There will be a sensor "deeply embedded" in the system, but it is highly unlikley to be in the nature of a "switch" or anything mechanical that you can manually operate.

    It is probably located under the CPU or similarly embedded beyong reach. If you saw it would you even know what it looked like? (it will be a thermistor or a thermal diode, there will be nothing necessarily to suggest what function it performs.

    Also you will not know how it acts, it will not be a switch, rather a component that changes its value dependent on temperature. So finding it will be of little use I suspect.

    If you have a schematic for the motherboard and can locate a clean access to power, you could power the fan directly, but that would mean it would run all the time.

    What is your level of electronics knowledge and skill though? It is REALLY easy to economically destroy a laptop...
