    Acer laptop fn key doesn't work


    For some reason my brand new Acer laptop doesn't have a functioning fn key. Everything else is perfect though, as it should be coming right from the box. I can't quickly mute, change screen brightness or put my computer to sleep. This is very annoying. Do I need to install a driver even though the rest of my keyboard is functioning properly? Help!

    Sometimes the Fn keys work in weird ways that I don't expect... have you looked in the manual? Chances are there's some Acer-specific utility that lets you configure how they work (you may be able to change something in the BIOS that has the same effect, but I'd look for the utility first).

    In the case of this instance there appears to be nothing different I have to configure. The manual shows the hotkeys and what they are supposed to do but the fn key is useless. Do I have to turn on hotkeys somehow? Can that even be done?

    I imagine there will be a way (unless you're *really* unlucky and have a busted Fn key, but I think that's unlikely). What model of Acer is it? Did it come with Windows 8 pre-installed from new?

    I know some laptops are set up the wrong way round (to my mind anyway) so that pressing F8 (rather than Fn+F8) would Mute/Unmute, and if you wanted a regular F8 you had to press Fn.

    Does it affect all keys or is it just the F1-F12 keys at the top of the keyboard - for instance does Fn+up arrow/down arrow change the volume?

    You might find something in the BIOS settings (but care is needed as changing BIOS settings can cause all sorts of problems).

    Close Windows 8 using the option to Restart (rather than Shut Down) and press the key (probably F2) to get into the BIOS settings. Then look to see if there are any options about Hotkeys or similar? If you don't find it then I'd always be sure to Discard Changes on exit from the BIOS settings, just to be on the safe side.

    Try re-installing Launch Manager Application, might solve the problem:Download

    Re-installing launch manager seemed to be the popular fix that I have been told but unfortunately it didn't help, and yes, it unfortunately is for all keys not just the F1-f12 keys.

    Did you get a chance to look at the BIOS settings? There may be something there?

    So I had my school IT department check BIOS and tried the Launch Manager and when I brought it back to the store I got it from they discovered it was a defective computer. Thanks so much for the help though everyone.
