Ah thanks, this is what these are for, thermistors. They are supposed to monitor the temperature somewhere I suppose? Attached to the batteries? The power supplies? The computer won't start without these I understand? Sorry I am a bit of a newbee with HP 1000's. Have not tried to power mine quite yet. Marc
