screen dim on battery

Hopefully this is an easy question...I'm just not sure where to start looking for the answer.

When I boot up my Latitude D600 on battery only, the screen is not its normal brightness and is dim. Almost unreadable.

It used to not be this way. It used to boot up nice and bright.

While on the AC adapter, it boots up bright. Also in the docking station with the big monitor.

So, either I inadvertently changed some setting or I'm having a h/w problem of some kind.

Any help on where such a setting would be?

thanks

It may be a BIOS option that controls that setting. I have a D600 and could not find any specific setting for it in the Power or Display settings either. On an IBM ThinkPad it will have a Windows-based configuration utility that allows you to choose those types of display settings, but apparently Dell does not have that. Try rebooting and go into BIOS setup to look around for screen brightness.

When you boot up your laptop hit the f2 key it will bring you in to the setup screen in there you will be able to ajust the cotrast of the pc when you have it pluged in your using the battery. hope this helps

i dont know if this is the way it is supposed to be, but i find it to be quite nice

when i change the setting for the LCD brightness on either battery or plugged-in; it keeps that setting till i change it manually by using the Fn+UP or Fn+Down and it adjusts it globally, even after shutdowns, reboots, etc.

so when i switch to battery it dims to 50%
and when i plug it back in, it goes back to 100%
though if i change the plugged in to 50%, it doesnt change when i unplug it; and vice versa
