XPS12, Model “P20S”, with i7 processor. 2.5 years old
All was working well and the computer went dark. The only sign of life is:
- Press and release the power switch. The keyboard backlight (and the internal fan) turns on for about 0.5 seconds, then off. The indicator light associated with the power switch stays on. Occasionally, the keyboard backlight (and fan) will again turn on about 5 seconds later (and turn off 0.5 seconds after that)
- Press and hold the power switch for about 6 seconds (which should turn the computer off), and the indicator light does turn off. The above process can be repeated, same results.
Nothing on the display. No beeps (I looked at the list of the Beep Codes, but the system doesn’t make it that far)
Any thoughts or suggestions would be appreciated.
Thanks.
