My laptop will no longer shut down, hibernate, or sleep. When I choose to shut down the window sits at logging off, and will not change. When I chose to hibernate/sleep it will sit at a black screen, but do nothing more. The fan still blows hard, and it will not come out of the "hibernate/sleep" I am using Windows 7 Home Premium(64 bit) and my specs are: Version: 6.1.7600 Build 7600 Model: HP Pavilion dv5 Notebook PC Manufacturer: Hewlett-Packard Processor: Intel(R) Core(TM)2 Duo CPU T6400 @ 2.00GHz 2.00GHz Ram: 4.00 GB 64-bit operating system Also, my computer will successfully shut down when I am running it in safe mode (which I am doing now, with networking enabled). Thanks in advance for the help, and I'm no whiz when it comes to computers, so if I am missing any information just tell me. EDIT: I just remembered I had this issue when I first installed Windows 7. Then after a 2 days it started to work properly. Now it has started again, but this time it has continued for about 5 days.
