Power On By PS/2 Keyboard or Mouse. Turn this on if you have an oldstyle
keyboard or mouse that has a round connector. Most PCs should
wake up from newer USB keyboards or mice regardless of this setting.
Restore on AC Power Loss. This option lets you decide what happens after
you??™ve cut power to your PC. Set this option to Always On if you want
to turn on your PC with a switch on an external power strip.
As you might??™ve expected, some experimentation may be required at this
stage.
When you wake up your PC, Vista may require a password before it resumes
your previous session. To turn this off, return to the Advanced Settings window
(Figure 5-3), expand the Additional settings branch, and set the
Require a password on wakeup to No.
Sleep and Hibernate troubleshooting
For the Standby, Sleep, or Hibernate modes to work properly in Windows
Vista, your PC has to cooperate. If it doesn??™t, you might experience a problem
such as:
Trim the Fat | 221
Performance
No sleep. Windows won??™t go to sleep at all; either nothing happens when you
try to stand by, or the system just crashes in the middle of the process.
No wake up. Windows won??™t wake up after going to sleep, or Windows
simply boots normally instead of resuming your previous session.
No more sleep. Windows goes to sleep or hibernates once, but once it
wakes up, it won??™t go back to sleep until you restart it.
Features are unavailable. Some or all of the power management features
and settings discussed earlier are grayed-out (disabled) or missing.
