I've been given a laptop at work, a Dell Inspiron 1545, which I find pretty good, except for the F1-F12 keys.

Being a programmer and a poweruser of several programs, I need to use them a lot, and here they are inverted, you need to press the Fn key to get access to them, and you get the volume up/down, brightness. wireless on/off stuff without pressing the Fn. Is there any way (or hack) to make them the other way around?? F1-F12 just by pressing the key, and the extra functions using Fn?

Its driving me crazy! Specially turning off the wireless when I want to rename stuff!

I didn't manage to actually do it, but shutting down the wireless in the middle of a download because I wanted to rename a file was my top fear until just now. Thanks for asking this. – Adriano Varoli Piazza May 22 '11 at 15:25

In many Dells there's a BIOS setting that will default Fn to on. There probably will be in the 1545.

Thanks it worked!! :D – bangoker Jun 6 '10 at 16:23

I found 2 solutions. The easiest:

Control Panel - Hardware and Sound - Adjust commonly used mobility settings - Fn Key Behavior

Thanks! This worked on my Inspiron too, and it's much simpler than mucking with the bios. – Adriano Varoli Piazza May 22 '11 at 15:24
For some reason I'm not seeing the "Fn Key Behavior" settings on my Lenovo Edge (Windows 7 64 bit). – ripper234 Sep 1 '11 at 8:46

On my Dell XPS 15, it seems to be as simple as me accidentally pressing the Fn Lock button behind the Escape key. If you have this problem, simply hit Fn+Esc and it should revert back to normal, without having to go into the BIOS

In Win7, you just go to Windows Mobility Center and change the Fn key behavior.
