Just installed Windows 7 Ultimate for my laptop and everything runs great but I have a problem when it comes to the laptop switching over to internal battery power. Whenever I disconnect the power from the laptop, the screen gets all white and I lose alot of color definition. Its to a point where I can't even see what i'm doing. Once I plug the power cord back in, all is well again. Dell D610 Intel Pentium M 750 (1.86GHz) 512MB DDR2, 400MHz ATI Radeon X300 64MB 60GB Hard Drive, 5400RPM 14.1" SXGA+ (1400x1050) LCD I know I need to upgrade but any help with this is greatly appreciated.
