Area-51m, not booting, #3

Hey guys, I had the laptop on and running fine and just came back to it dead while plugged in and charging. Power button won't turn it on now and I'll get a random yellow alienhead flashing briefly now and then but no activity at all.

I tried unplugging the laptop and holding the power button for a minute before plugging it back to reboot but nothing.

Never opened this laptop up to upgrade or whatever. Can anyone advise?
