Using Power Saving Modes
When you use a battery as the source of power for your notebook, you can take advantage of power management settings
to conserve battery life. In addition to the normal operating mode, which allows you to turn off specific devices, your
notebook has two distinct power saving modes: Standby and Hibernate. When using battery power, be aware that the
notebook automatically enters Hibernate mode when the remaining battery charge drops below 5 percent, regardless of
the power management setting you select.
Note:
If the battery level falls below 10 percent, you should either attach the AC adapter to recharge the battery or shut down
your notebook and insert a fully charged battery.
