A few weeks ago, I installed AVG PC TuneUp on my Windows 8 laptop. It recommended that I disable hibernation – this would increase performance. From that point, start-up and shut-down became excruciatingly slow, considering for the speed of my laptop (a 4th-gen i7 with 6GB RAM).
Unfortunately, it took me a while to correlate the slow speed and the fact that I disabled hibernation.
After re-enabling it manually (I had uninstalled TuneUp, and was not willing to re-install it), start-up and shut-down resumed to normal speeds – 8 seconds to start up, and 5-10 seconds to shut down.
My questions: Does the Windows start-up and shut-down procedure have some sort of reliance on the hibernation file? If so, does anyone know what it is? Any other information about this would be appreciated as well.
A little background to the speed and/or performance changes:
These are the symptoms that I experienced:
- Start-up would take up to ten times longer than usual,
- The login screen would take forever to load up (after boot screen, a black screen, and then the lock screen),
- After entering my PIN, it would take up to 20 seconds for Welcome to be displayed (sometimes the lock screen would pull down after entering my PIN and it thought it was idle),
- The loading up of the desktop would take quite some time, and the System process would use 100% disk and 40-50% CPU activity for about 2 minutes,
- Shut-downs occurred in a different manner: normally, Windows would show Shutting Down for about a second, and then the screen would turn off, but the power light would remain on for another 6 seconds and then turn off (indicating full system shut-down). With hibernation disabled, however, it would display Shutting Down for around 10 seconds, and then both the screen and the power light would turn off at the same time (indicating full system shut-down).

Windows 8 has "Hybrid Shutdown" enabled by default. In this mode, Windows doesn't shut down after logging you out, but enters hibernation. (Except when rebooting.)
Disabling hibernation forces Windows to revert to fully shutting down and booting up.
