The Power Options Properties window contains the following tabs:
l
Power Scheme — Allows you to select a power mode setting.
Select the Portable/Laptop setting to conserve battery life while the computer is in standby mode. If the Always On
setting is selected, the battery life may be much shorter when in standby mode.

l

key combination (sleep button), and closing the display.
