Hi. I've had my new iMac since Christmas. I turn it off at night when i go to bed, but i don't switch it off by the mains (plug) because its a pain getting behind the desk to flick the switch off. Every night while lying in bed, i have noticed a small light on my desk underneath the iMac, but i never thought anything of it, i actually thought it was a refection coming from my window shining onto the iMac/desk. Last night i decided to get up and see where the light was coming from. I was shocked to see a light shining from inside the iMac It was on the right hand side of the RAM storage. It looked as if the light was shining downwards, towards the desk. - Anyone know WHY the light stays on while the iMac is turned off? - Is it normal to do so? - Should i switch my Mac off a night by the PLUG ?
