Some devices just don’t play well with hibernation.

And BitLocker users shouldn’t be affected.) (This doesn’t affect the full disk encryption feature of TrueCrypt, just disk images. The solution for this is just to manually dismount your encrypted drives before shutting down, but it is something to be aware of. Users of encryption programs like TrueCrypt have reported that encrypted drives they had mounted before shutting down their system were automatically remounted when starting back up.


This is different from the regular hibernate feature. RELATED: What's the Difference Between Sleep and Hibernate in Windows? This technique can shave considerable time off your start up. Instead, it just refreshes your RAM with the loaded image from the hibernation file and delivers you to the login screen. When you start the computer again, Windows does not have to reload the kernel, drivers, and system state individually. Windows then alerts device drivers that support it to prepare for hibernation, saves the current system state to the hibernation file, and turns off the computer. At this point, Windows is in a state very similar to when it’s freshly booted up: No users have logged in and started programs, but the Windows kernel is loaded and the system session is running. When you shut down your computer with Fast Startup enabled, Windows closes all applications and logs off all users, just as in a normal cold shutdown. Fast Startup combines elements of a cold shutdown and the hibernate feature.
