I have a Compaq Armada 1750 laptop computer. I need to adjust contrast
and brightness. The F9 and F10 keys seen to have symbols indicating
contrast and brightness but when I push them it has no effect on the
screen. What am I doing wrong?

Hello cadillacjim1951,

Thank you for your question.

I suspected as much but checked to be sure with the following search
and found that the only thing you need to do is hold down the Fn key
while pressing the proper F key.

Brightness and contrast need adjusting.

Press Fn+F10 to adjust brightness. On models with passive matrix
displays, you can also press Fn+F9 to adjust contrast.
