Dell Inspiron One 2305 - Similar Issue Here.
I have a 2 year old Dell Ispiron One 2305. About 2-3 times a day the screen just goes black. It is a lighter, back-lit black, compared to the dark black when the machine is completely off. The power button is a constant white when this happens. The only way to get the machine to work again is to cycle the power button off - then on. It works fine for several hours and then goes black and freezes again.
I updated all drivers & ran it without back cover thinking it was a overheat issue. To no avail.......It still goes black and freezes. Any advice?
