My Packard Bell EasyNote TS11HR notebook does not have an option for dimming the display backlight. At night, my eyes begin to hurt because of the strong light from the screen.
My laptop is 2-3 months old and I am sure it has worked before.
When I click on the battery icon in the notification area, it says in my language (Danish): "the setting for light does possibly reduce the life of the battery". However, I cannot dim the backlight.
I have tried downloading programs for dimming the screen but they only make the screen darker, instead of dimming the backlight. I have tried updating my drivers and looking in the BIOS for a setting. I also plan to use an Ubuntu LiveCD to try controlling it. As of now though, the backlight is locked at maximum.
