Quick Windows Startup with Hibernate Mode

Windows No Comments

There is a way for your laptop to quickly start up. Just put it into hibernate mode instead of shutting it down.

  1. When you go to menu Start->Turn Off Computer, you will get a popup with Standby, Turnoff, and Restart options.
  2. Hold down the Shift key and the popup will change to Hibernate, Turnoff, and Restart options.
  3. Select the Hibernate option.

Hibernate will write the computer memory to hard drive so that when you next turn on the computer, it will put itself back to the current state very quickly by restoring the memory.

Note that eventually the system may not allow you to Hibernate (you will get an error)… at this point, you have to shutdown or restart the computer to clean up the system.

    • Run iTunes.
    • Go to menu Edit->Preferences->Advanced->General.
    • Make sure that Copy files to iTunes Music folder when adding to library is not checked. Hit OK.
  3. Go to menu File->Add Folder to Library…, select the folder containing your music, hit OK.
