We have a Dell PC that is switched off/shutdown (Mains still going into pc though), and every so often the HDD spins up for a couple of seconds then stops. Does anyone know why this is and if it can be stopped?

just to add - you are 100% sure it is (and only) the hard drive spinning and not another form of hardware? – Rudolph Nov 04 '13 at 13:29

When this happens nothing else turns on? (like monitor output, keyboard, mouse, power supply fan, LEDs on the front panel...) – pabouk - Ukraine stay strong Nov 04 '13 at 13:30

is the machine definitely off and not in sleep mode? – RJFalconer Nov 04 '13 at 13:31

It is just the HDD, nothing else powering up or turning on and is definitely shutdown :) – user170324 Nov 04 '13 at 13:39

is it Windows 8? I've heard that instead of shutting down it enters some sleep mode that can still perform some low-power tasks without fully waking up. – EliadTech Nov 04 '13 at 13:46

Could you please tell which exact model of a Dell PC is it? – pabouk - Ukraine stay strong Nov 04 '13 at 20:33

it could be some circuit issue with the motherboard! i have seen a laptop's cpu fan spins to max speed as soon as there is power (battery or ac adapter)! lucky that was still under warranty... – PatricK Nov 05 '13 at 00:55

optiplex 755 - Have checked all the wake up on lan/power savings options and nothing – user170324 Nov 08 '13 at 09:19
