Boot Snooze can reboot your computer and make it automatically hibernate/standby. The Boot Snooze is a simple tool that will:
1. Give you a choice to reboot and go into standby or hibernation.
2. It will then reboot your computer.
3. After the reboot, a small dialog with a countdown timer will begin.
4. After the timer is up, your computer will be put into the mode you chose.
Note: For hibernation to work, your computer must have "Enable hibernation" already checked under your Control Panel, Power Options, Hibernate tab.

Command line operation
REQUIRED parameters are:
- mode=[reboot|suspend] (reboot will reboot and then go to the hibernate/standby delay timer. suspend will skip the reboot and go straight to the hibernate/standby delay timer)
- method=[hibernate|standby]
- bdelay=# (where # is the number of minutes to delay BEFORE rebooting)
- adelay=# (where # is the number of minutes to delay AFTER rebooting)
e.g.: c:\path\to\BootSnooze.exe mode=reboot method=hibernate bdelay=0 adelay=5.
