My Fn Keys arent working properly. Please help!

When i first got my computer, i reformatted and reinstalled XP and everyhting worked fine. When i press the Fn key and volume/brightness/touchpad/output screen select/ wireless it all worked fine, and had an on screen adjustment window for all the options.

Since then i reformatted and was dual booting with linux and XP. Most of the functions never working in Ubuntu Linux though. Either had no function, or brought nothing on the screen so i could see what it was doing.

Now i have formatted again, and scrapped linux. I only have XP now. but... only some of the Fn Keys works, but i dont get the little popup window when i change anyting. Adjusting brightness and monitor switching works. But changing volume or disabling touchpad doesnt work.

I have all the same drivers installed off the driver cd that came with my computer.

Could ubuntu have messed something up? I thought this was all jsut software related... so i dont get it? Bios maybe?

Oh yeah, I have XP Pro, and my computer is Haier W36 (like anyone even knows what it is... but it all worked before)

Any help appreciated! thanks!

 

I've experienced similar problems.
not with linux but I too have had loss of use of my fn keys.
I too would like to know what is wrong.
If anyone could help us it would be appreciated.
