If I remember right, when my PC's go into Hibernate (either by the option in one of the logoff menus or the power button if it's configured that way), I get a Progress bar on the screen both when it goes into and when it comes out of Hibernate. Keyboard, Mouse, doesn't power the system up, only the power button.

For standby, it goes straight to the logoff screen (but doesn't really logoff), stays for a couple of seconds, then shuts down. On power up (either by the keyboard, mouse, or power button if so configured), the screen just pops up the same as when I hit Standby.

Do you get the Progress bar along the bottom of the screen on Power up after the post?
