My Dell Inspiron 1520 always start with part (right side) of the screen blanked or black space. Windows XP start up screen doesn't show, just the logon already with black space. It's like using 800x600 resolution while it should be 1280x800. I tried the settings but to no avail. The only thing that will solve this is remove the battery pack first before starting but I know it's not the proper way to solve the problem.
