Specs: MS XP Pro 5.1.2600 build, Intel Pentium M 1.60GHz.

When I unplug my laptop the screen darkens drastically.
How can I stop this?
I have tried to find a power setting or something to change this to no avail.
Can anyone help?

In order to save the battery many laptops cut the brightness when on battery. You might have a menu for setting up when on battery. My Dell Latitude has one in the BIOS.

You should have a brightness control on your keybaord (usually one of the F keys + the Fn Key). It has dual memory mode. One for bettery and one for plug. Next time you have it on battery, adjust the brightness from the keyboard to a new default level.

Is it possible that the battery is on it's last legs?

I tried using different combinations of Fn + keys and discovered that the Fn key + up or down arrows made the brightness respectively more and less.

The battery is brand new no problem there.

Thank you all. --NATO
