screen fades slightly when on battery not power plug
why does screen fade slightly wwhen on battery noy power cord
Gary Tibbs, check in your system setup to see that both the "Brightness" and "Brightness (AC)" levels are at their highest.
1 Turn on (or restart) your computer.
2 When the DELL logo appears, press <F2> immediately.
You might also want to check your power setting as the power settings have a power saving mode to save battery life it dims the screen to conserve power
maybe ur using an automatic brightness setting did u check that
