I have an old Averatec PC that runs XP. It hasn't been used for ages, but we just dug it out, and I figured I'd get it running for my granddaughter.
The keyboard no longer works, but I did hook it up to a USB keyboard. My problem is that the laptop screen is way too dark. But the non-functioning keyboard has a blue labeled Fn key in the lower left hand corner, which should tie to the brightness, volume and screen position mapped in blue to the F3 thru F10 keys.
Of course, there is no Fn key on the USB keyboard I'm using. I'd like to be able to determine if it's a setting problem, or the backlight before I go to the trouble of ordering, and installing a new keyboard.
Is there any way to duplicate the Fn and brightness keys with a non-laptop keyboard?
