Have of course sought help on a more appropriate board, but got an answer like 'find out which part is faulty and replace it'. Very constructive. So in the hope somebody can point me in the right direction here goes:
Her Toshibaba Satellite Pro L300-21F 'just stopped working'. Of course its 18 months old so out of warranty. A friend's techie had a quick and somewhat reluctant look and pronounced that either the motherboard or CPU was dead.The power supply light and battery light come on. When you press the power switch, the power light comes on and the fan kicks up. There is a click from the CD drive but I know drives will do that when powered. The hard drive is silent and no lights appear on it. There is no message or display on the screen. I removed the battery, the memory stick, the CD and hard drives and keyboard and still nothing. Not even a beep of protest that the memory or keyboard are missing. I've looked at the board and can see no sign of overheating but I didnt really expect to. I think the guy was right. But how do you tell if its the board or CPU that is at fault? I was told the CPU should get warm but I understand the board switches it on so its like Catch 22? Yes I know it will have to go to a specialist but I love a puzzle and would like to learn something too Any ideas and help much appreciated. And apologies for the OT thread
