Whenever I'm trying to put my laptop on fullscreen mode with F11, but I don't hold in the Fn key at the same time, it only mutes my laptop, and it's really annoying! I know it's possible to change it, but I can't find out how.

I've looked everywhere, but nothing helps.

I'm using a Windows 8 Toshiba.

I'm not sure about the other details. I guess that "SATELLITE C850D-11F" might help?

This question came from our site for professional and enthusiast programmers.

How do you know it's possible to change it? Maybe there's some way to enable "Fn Lock" (like Caps Lock etc.), but I haven't heard of a laptop where you can change it permanently yet. – gronostaj Jun 7 '13 at 22:49
@gronostaj You can usually change it permamently in BIOS. Works almost always – user 99572 is fine Jun 12 '13 at 13:27

Usually making the F-keys work as F-keys require changing a BIOS setting, as described in these questions:

But apparently, at least on some Toshiba notebooks, you can change the F-keys' behaviour directly in Windows, as is described in this Toshiba help article:, and on this website:

In case those sites ever go down, here is the screenshot of the Toshiba help article:

You would need to select "Standard F1-F12 mode" in the category "Function Keys mode".
