I have an HP 6735b laptop. It previously had Windows Vista Business Edition and I upgraded to Windows 7 Professional. After the move my laptop will not start without being plugged in. I downloaded all the drivers available for it from the HP site and ran windows update multiple times with no success. The laptop boots fine, but stays on the screen that says "Starting Windows" and the windows symbol just keeps flashing. While on this screen if I plug it in it immediately finishes booting like normal and the laptop works fine. In addition it will not shut down without being plugged in, it will just stay on the screen that says "Shutting Down". I'm not sure what to do or how to fix the problem. Any help or suggestions would be welcome.
