Until a couple of days past, when I unpluged the power cord or started the machine on battery the screen brightness did not change. Now when I unplug the power or start on battery the screen brightness goes quite dark. What causes this and how can I remedy it? I've checked the settings and nothing has changed.

Check the screen settings in the power option settings in control panel or in the start menu if your laptop has a "tools" option such as the IBMs.

Did that. Every thing is as it has always been. If I do change a setting, the results are the same.

Which is unusual.

The 'norm' is for the screen to become less bright when switching to battery power to preserve battery life.

I am/was aware of that, but it never did it before, the screen always remained at the brightness I had it set to. Now it is so dark that it is hard to use.

Is the battery dying?

I don't think so. Battery metre says it is ok.

it does sound like it gone onto power saver mode for display, You need to check it out, also try pressing fn key and the brightness key on mine a HP its F7 and F8 key

Mine does this, I know it's normal but never seen a setting for it. Is it in the BIOS menu perhaps.

I can change the brightness with Fn and two up/down arrow keys (Dell). It's just a nuiance. Have to live with it I suppose.
