No there's nothing like that at the back. I used it last on Friday. I nipped out the office and came back an hour later. It was in sleep mode but was not responding. I had to turn it off at the wall. It wouldn't start back up after that. Then after a bit of fiddling about with the connections it started up again. Stayed on for about an hour or so then turned off again. Came in this morning and wouldn't start up.
Nothing at all.
Tried that Freddy. Power supply is good !!!
Sorry Freddy. I switched the cables from the monitor and the tower. Both cables powered up the monitor but not the tower
There's no led light lightning up or fan trying to start. Computer was bought September 2012. So not that old. No warranty either.
