Left Dell desktop on when called to dinner. I was on BCF. Came back to find it...dead. Disconnected power, all peripherals and turned back on - nothing. No light. I did notice that connecting the monitor to the adaptor caused the green light on the monitor to turn yellow but this may be an unrelated problem. I have two monitors (older Dells) and both do the same thing. No choice but to take it into the shop and hope for the best. I think this Inspiron is about 3 or 4 years old - can't recall. Luckily my wife's Dell laptop is still working...
