Hi

My LCD screen has gone completely black. i dont know if it's a BIOS issue or mother board.  But the laptop doesnt even recognise the laptop screen. i've got the laptop plugged into a second monitor that's the primary and only monitor.

i see the following indicators

1 Amber and 4 white (more regular )

2 Amber and 7 White ( intermittent )

amazingly it all went wrong after my warranty expired
