2.1.1 Managing Your Notebook’s Power
See 7.2 Battery for more information on getting the best performance from
the battery packs.
Use your notebook connected to an electrical outlet as often as possible as
the battery life expectancy is affected by the number of times it is charged.
Your notebook comes with built-in power management. You can configure it through the Power
Options program in the Control Panel, to sleep, hibernate, and wake according to the specific
situations.
The Advanced settings can be accessed via Start > Control Panel > System and Maintenance
> Power Options.
On the Select a power plan page, click Change plan setting under the plan that you want to
change.
Click Change advanced power settings. Expand the Power buttons and lid category to
configure the settings.
When leaving your notebook unattended for the long period, place it in Standby or Hibernate
Mode. You can exit either power management mode by pressing the Power Button.
2.1.2 Power Management Modes
2.1.2.1 Sleep Mode
This mode conserves power by switching off the hard drive and display after the preset period of
inactivity (a time-out). When Sleep Mode is exited, your notebook will return to the same
operating state it was before entering sleep.
In Sleep Mode, if your notebook loses power from both of the electrical
outlet and the battery, the data in your notebook may be lost.
