Hi,

I have an Inspiron 640m and I have noticed that before the startup of Windows (probably before QuickSet is started) I can not control the volume, neither with the front panel (MediaDirect) buttons nor with the Fn+PgUp/Dn button (the mute buttons don't work either). This can be really annoying in a situation when I turn the computer on in a class or conference, and I can not silence the Windows startup sound!!

The weird thing is that screen brightness can be changed with Fn+arrows just after the computer is turned on.

Does anybody know how to control the volume before or while the OS is being loaded?

 

Thanks.
