    Hi... I've gone and done a bad!

    I've got a CF31J with the discrete ATI graphics... but that card appears to be faulty... so I'd set the gfx to energy saving in the bios... all is good in the world... and it's been that way for a couple of years...

    Well... today I'm just playing about and accidentally set the gfx selector to performance in the bios... result is a black screen from boot!!!

    I can enter the bios - tapping F2 at start-up results in fans staying on and no hard drive activity... so I hope I can navigate with the keyboard to switch back to Intel graphics... but I don't know the exact keypresses to do this...

    Can anyone help with this? Or even the exact keypresses to reset bios to default?

    Something along the lines of 'to reset bios to default' right 5 times, down 3, enter, left, enter, up 3 times, enter, right, enter

    Its a CF-31J

    Thanks!!

    Try plugging in an external monitor.
