    I tried to get to the bios menu on my old asus as i wanted to change the primary boot device to cd to system restore the pc from a disk. Basically no instructions came up to enter the bios menu and i ended up trying a few different function keys. I must have done something as now when i tun the laptop on all i get is a blank screen. This now happens every time i turn on. Im wondering if taking the laptop to bits and trying the 'remove bios battery' trick would work. What do you guys think? Cheers

    That might work and you could try it. It seems to me that it needs a bios update and few other things as well. Try removing the CMOS battery for about a minute and see what happens.

    Could be coincidence and the backlight just took that moment to burn out.

    Look closely at the screen in the dark--anything at all? Connect an external monitor up...anything?

    Most laptops allow you to switch from laptop display to external display with a keyboard combo (FN+some key). Try using that combo.

    My guess; GPU.

    EDIT: Or actually, try what gerryf19 said, it may be you have changed it to turn the monitor/s off completely, and show nothing! Try a combination of Fn+F7 or 8 maybe.

    are you sure you didn't change the memory setting or some other settings when you were in the BIOS?

    try to remove the batery (main battery not the CMOS one) and the ac adapter and push the power botton for a couple of minutes.

    If this doesn't help and if you have 2 x 512MB of ram try with one module only. Try with swipping the ram too.

    If your GPU was fine before entering the BIOS, it should be fine after too.
