Black screen, only power LED working

So, there goes my laptop.

My trusty Acer Aspire One AOA 150 ZG5 gave up on me during startup. I was in a hurry, and noticing i had left my USB stick in and that the lappy fanatically tried booting from it I jerked it out. Then the computer rebooted and died.

Now when I push power, nothing happens. The fan starts, stops and starts again eternally, the LED for battery and power shows green, but the screen is not powered, just black and dead. Caps lock and numlock doesn't work, so I know windows isn't running in the background.

My guess is i fried the BIOS or something when removing the USB during boot.

Now what?? Do I have to blind flash it? I already took the hdd out and made a backup. it's all there.
