i have an hp envy 17 i bought in december, running windows 8
i was prompted to do a bios update, it went thru the update and then reset to a black screen i let it sit for about 30 mins or so. Now it just boots to a black screen never posts i never see anything appear on the monitor i hear the hd and fans start when i power it on but nothing appears.
i have disconnected all usb devices that were on it i tried booting it on only ac power and only battery power, no change. Prior to this it has worked great i have had no issues with it.
