I'm using an HP Pavilion notebook and XP Home. I use in in a desktop environment; i.e. external monitor, keyboard, and mouse. The notebook is shut.
When I perform a standard Windows XP Start/Turn Off Computer/Restart function, the notebook shuts down instead of restarting automatically. It does not shut down completely, it seems to go into a hibernaye mode of some sort, but to continue I have to open the top, press the Power button to finish the power down process, then press the Power button again to start up.
