Hello, so I have this problem, I own an Acer Aspire One, and yesterday my Fn key stopped working when I try to increase or decrease the volume (Fn+Up Arrow / Fn+Down Arrow) but it still works when I adjust the brightness (Fn+ Righ or Left Arrow). Any solutions? All of the programation is going nuts, before I could for example change a song in windows media player by using two fingers over the touchpad, and now I can't. Help, please?

Thank you
Really sorry,i should have explained you properly.

Go to start and type msconfig

Now select '' normal startup and reboot''

Does it work now? If no then

Do you have something called ACER LAUNCH MANAGER ?

This is needed for your function keys to work properly.

Download this


Extract run the setup file,Install and reboot,does your function key work now?

If not download this


Open the extracted folders until you can see the setup.exe file.
Right click on the setup.exe file a choose properties.
Under Properties choose Compatibility tab

Now you can see an option '' run this program in compatibility mode

Check mark it and select windows vista service pack 2

Click ok and run the setup file and restart.Let us know if it works

Thank you

You did not provide the model

Anyway ,search for ATK drivers for your model.Reinstall it and restart
yup,thats the way. download atk from asus member page, uninstal your atk,then instal the newly donloaded atk..that should fix the problem :)
Thank you
Hello, I have the same problem.. Except my computer is asus instead..
Can someone help me with that?

Thank you
Try to check for

QtZgAcer entry in msconfig

Is this checked? If not check it and restart your PC

If that doesnt work reinstall your hotkey drivers for acer website
I actually had to google msconfig lol I know nothing about programation and stuff. Ok, so there is no QtZgAcer entry in msconfig, and everything seems to be checked anyway. And I don't seem to find any "hotkey driver" for my acer. Thanks anyway.
