Hi, I think I've got all drivers and bios up to date but since 6 months (it (quick launch buttons for controlling display brightness) had used to work earlier fine) I've a problem with HP Quick Launch Buttons. Volume buttons are still ok but display brightness and microphone mute haven't worked ok - when I've pressed one of this buttons I've been getting a small pop up window with the label "HP Hotkey Support" with no info inside, no action button to click.
I have installed sp49104.exe and buttons work again but the pop up window keeps popping up.
Do you have any update of QLB (sp49104.exe is from 2010)?
