Batteries and Power Management
Managing Power Consumption
When you're running your notebook on battery power, you'll want to maximize operating
time without compromising performance. Your notebook includes several power-saving
features that will help you do this.
• During idle periods, the notebook automatically enters power-saving modes after
specified timeout periods. You can adjust these timeouts to suit your working habits.
• You can also manually send the notebook into a power-saving mode whenever you
need—see "To manage power manually" on page 50.

How the notebook manages power automatically

Your notebook automatically turns off the hard disk and display, goes on standby, and
goes into hibernation based on values set in Power Options in Control Panel.
