    In that case I suspect the FN key itself is the issue which means you would need to get a replacement keyboard as I said.

    Here's a possible source for the keyboard: Toshiba Satellite C55-A5285 Laptop Keyboard Replacement

    I just did a compare of the two units mentioned in this thread and I do see differences between the two. Specifically, for starters, the latest BIOS version for one is dated 9-26-2013 (v1.20); whereas, the other is dated 2-14-2014 (v1.60):

    Satellite C55-A5285 Support | Toshiba

    Satellite S55-A5295 Support | Toshiba

    Now, maybe the differences in the BIOS versions make no difference at all regarding your issue so keep working with Strollin and I'm sure he'll help you get through your current issue.


    Good luck,

    What am I, chopped liver? This still sounds like software/BIOS issue going by wws's last post.

    OOPs, sorry about that popeye! I guess I was just focused more on Strollin's responses because he had started to make some very specific recommendations. Unfortunately, I have a difficult time remembering everyone's contributions so I apologize again.

    Also, I'm glad that you agree it could still be a BIOS issue.

    No problem, just yanking your chain. Strollin mentioned it could be a hardware key problem but then wws

    No problem, just pulling your chain, couldn't resist. Strollin mentions possible key hardware issue but then wws says the keys work as normal function keys but just the blue upper functions aren't working. This is normally BIOS and/or driver issue as I know you are aware.

    Wws hasn't replied in a while, hope he got it fixed.

    Since the FN key doesn't work with a keyboard tester as Wws reports here, I'm still inclined to believe it is the FN key itself that is defective.

    Hi Strollin,

    That makes some sense to me. However, since I have never actually used a keyboard tester to test a specialized function key that is primarily controlled by the BIOS, you may be exactly right in your assumption. Its just that I have seen so many FN key issues put to rest by either a BIOS update or an OS incompatibility statement from the manufacturer that I zoom in on that as a primary cause. I also noticed the OP mentioned the following:


    This happened under Windows 8 too. Toshiba has a keyboard driver for this laptop model for Windows 7, but not 8.1.
    Now, the above statement would imply the OP may have upgraded all the way from Windows 7, and since his latest BIOS version is 4 versions earlier than yours, I suspect there are distinct differences between your laptops. With that said, I am hoping you can guide him through to a final fix but it also seems odd that the OP has already contacted the manufacturer, the manufacturer told him it was a corrupted OS, and they don't even offer a driver for the Windows version he is attempting to troubleshoot.


    Good luck,

    Hey guys.

    Sorry for the late response,I had a few tests at college. I am still experiencing this problem.

    my2cents, I bought this laptop with Windows 8 (not 8.1) preinstalled. It never had 7 installed on it as far as I am aware. Should I try flashing that other BIOS? I am a bit hesitant to do so, because I don't want to render the laptop unbootable.

    popeye, strollin, This could be a hardware issue, but I personally am still leaning towards it being either a BIOS issue or an OS issue.

    Thanks for all your help guys!

    Above is a picture of where the keys can be set to "Special Function Mode" or "Standard F1-F12 Mode". This screen shows up when you type "System Settings" from the 8.1 startup screen. The BIOS is 1.60 and the EC is 1.20.

    Hey, thanks for the response.

    I saw that settings pane, and the box is selected as "Special Function Mode". May I ask what model of laptop you have and what the OS is?

    I am running BIOS 1.20 from Toshiba. I see version 1.30 on Toshiba downloads page, but not 1.60. Could you provide a link please?

    Thank you,
