When I detach my XP Dell Latitude D620 from it's power cord the screen is barely visible and looks very washed out.

 

I've tried resetting it in control panel but the settings don't seem to stick. It also does this when I boot up in Linux.

 

I think there was a setting in the bios that I adjusted. I'll check the bios setting and report back.

 

I get the same problen now with my other notebook, Dell e6410, win 7.

Hi,

How old are the batteries? Do they indicate that they are fully charged just before you switch to battery power?

Keep us posted

What settings in which part of control panel have you been adjusting ?

 

Since these are both laptops I would be inclined to look at your power settings. Under 'power plans' there is often a setting to adjust the screen brightness when running on battery. It is possible that it is this setting which is set too low.

 

Your remark 'very washed out' could suggest that your contrast is set at the wrong level. Have a look at the 'Display' section of control panel and see if adjusting colour makes a difference.

 

Any chance you could publish a couple of screen shots to show the difference in these two condition ?  For instructions on how to do it, if you haven't done it before, see Stolen's instructions at #2 in this topic -
