7 The Power System (Vista)
7.1.2.2 Hibernate Mode
In Hibernate mode, power is conserved by system data being copied to the hard drive, and
your notebook is completely shut down. When Hibernate mode is exited, your notebook
will return to the same operating state it was in before entering Hibernate mode.
Hibernate mode can be enabled/disabled in the Power Options window.
If enabled, your notebook will go into Hibernate mode if the battery charge level becomes
critically low.
Depending on how you set the Power Management Options in the Power Options window,
use one of the following methods to enter hibernate mode:
• When you close the lid of your notebook
• When you press the power button
• When you press the Start menu power button
• Start >
The settings can be accessed via Power Options: Advanced settings window. See 7.1.1
Managing Your Notebook's Power.
To exit Hibernate mode, press the power button. You cannot exit Hibernate mode by
pressing a key or the Touch Pad. For more information on Hibernate mode, see 3.1 Turning
Your Notebook On and Off.
7.1.3 Power Options Properties

7.1.3.1 Select a power plan
Windows Vista provides three preset power plans, Balanced, Power saver, and High
performance. Each plan has different time-out settings for turning off the display and
entering sleep mode. You do not need to make any further adjustments to set the
performance level.
To change setting for the plan, click the following three items on the left pane of the Power
Options window.
• Choose when to turn off the display
• Change when the computer sleeps
• Adjust the display brightness
After selecting a plan, you can see the percentage of battery charge remaining and active
power plan by moving the mouse pointer over the battery meter icon on the taskbar.
For more information on changing advanced power settings, see the Windows Help and
Support.
