I have installed windows 7 ultimaite on my laptop DELL inspiron 1545...then, I installed the relevant drivers......once I installed the windows 7 display driver after I download it from DELL support site........I experienced a problem in display
driver as follows:
1- when the laptop on Battery....then I boot the laptop, it going on normally but after 1 minute or two.... the display shows color rubbish and the whole system stopped...i cant do any thing that make me to do the forced shut down from the power button..to get rid of this problem.
2- when the laptop on charger power this problems disapear.
3- I tried instead to install the Vista display driver.....I noticed that problem disappeared but with not complete function such as I cant control the brightness of the display neither from the keyboard didcated buttons nor from the control pannel.
pls advise abt that...thnx
