Lori:

While I do not guarantee this procedure will work, you might try pressing the FN key with Escape. This is referred to sometimes as the FN lock function. It is unfortunate that a growing number of new computers these days are configured by default so that the function keys do not work as function keys by default. My preference is to avoid altogether the need to lock the FN key by asking the seller (and paying extra for this) to program the function keys in the BIOS to work as function keys. Remember, the FN Escape method may (emphasize may) not work on your system. This is merely one suggested approach to attacking the problem.

Yours sincerely,

Curtis Chong
