I have an ACER Helios which completely out of the blue stopped booting. When I plug in the charger the charge LED will be orange, eventually changing to blue if you charge it to full, but when I press the power button, I get the second LED light up blue for around 3 seconds, then turnoff. No boot, no display, no fans. I've tried the battery/CMOS reset hole on the bottom, as well as opening it up and trying it with no battery connected at all. No dice. Has anybody ever come across anything like this before?
