Im just noticing that the function keys at boot time do not "functoin" as such, even when locked or while using the 'fn' key.
With my wired keyboard I can boot into the BIOS or a secondary boot device by selecting a corresponding fn key. In my case F2 for BIOS or F7 for BBS boot.
Its a problem when I need to boot into my BIOS, or an alternative operating system on a secondary drive..
