Power Saving Modes

Notes on Using Power Management

If you find that an application exhibits unexpected behavior (such as reduced video quality) after returning from a power saving mode, you should close that application before your notebook enters a power saving mode.

For maximum audio and video performance, use PowerPanel to select either the AC Power Profile or the Power Management Off profile.

If your battery level falls to less than 10 percent, you should either attach the AC adapter to recharge the battery or shut down your notebook and insert a fully charged battery.

When the internal backup battery is low on power, it may not be able to boot your system properly. You can correct this condition as follows:

Plug in the AC adapter and allow the notebook to charge for one hour while the power is on. Do not use the notebook during this time.

After one hour, turn the power off and then on again. To charge the internal backup battery fully, keep the AC adapter connected for more than 24 hours after turning the power on. You can use your notebook while charging the battery.

The operating system may become unstable if a lower power state such as Hibernate is initiated and then changed before the operating system completely enters the lower power state. To restore the notebook to its normal operating stability, close all open applications, and slide the power switch forward and hold it there for four seconds or more to completely shut down the notebook.
