ipaq 22xx backlight control "stuck"

[footman]

Hi

as title, I am unable to move the slider either when on battery or power, just get the annoying bleep.
any ideas?
TIA

that happened to me before
I installed some freeware tweaking software, but after I uninstalled the tweaking software the backlight slider won't work
it's nothing a hard reset won't cure
