Reminds me of my last visit to my granny's house. She had put a computer in the guest bedroom and it wasn't working. Turned out the computer was fine, it was how they had plugged it in. Or hadn't, as it turned out. Basically all the power cables were plugged into plug-boards, for some reason the plug-boards were plugged into each other and the only plug going into the wall was attached to another plug-board, which had nothing plugged into it. Not to mention the cables that connected the computer parts to the computer were all tangled up with the power cable like leftover spaghetti. Took me about half an hour to get everything unplugged, untangled and put back together again.
