Why is my Windows 7 laptop crashing when I close the lid? My laptop is an Asus UL30A, Windows 7 Home Premium, which I bought new in Sept. 2010. Over the last couple of weeks, it has changed its behavior. It used to go to sleep when I closed the lid, but now it crashes and I get the "windows didn't shut down properly" blackscreen when I open it back up and hit the power button. This also happens if I try to put it into sleep or hibernation mode using the start menu, before I close the lid. I have checked my power settings and they seem to be correct. Other ideas?
