3 Power management
Setting power options
Using power-saving states
The computer has two power-saving states enabled at the factory: Standby and Hibernation.
When Standby is initiated, the power light blinks and the screen clears. Your work is saved to memory.
Exiting Standby is faster than exiting Hibernation. If the computer is in Standby for an extended period
or if the battery reaches a critical battery level while in Standby, the computer initiates Hibernation.
When Hibernation is initiated, your work is saved to a hibernation file on the hard drive and the computer
turns off.
CAUTION: To prevent possible audio and video degradation, loss of audio or video playback
functionality, or loss of information, do not initiate Standby or Hibernation while reading from or writing
to a disc or an external media card.

WARNING! Do not charge the battery while you are onboard aircraft.
When you are charging or calibrating a battery
●
When you are installing or modifying system software
●
When you are writing information to a CD or DVD
●
When you connect the computer to external AC power, the following events occur:
The battery begins to charge.
●
If the computer is turned on, the Power Meter icon in the notification area changes appearance.
●
Using external AC power 17
When you disconnect external AC power, the following events occur:
The computer switches to battery power.
●
The display brightness is automatically decreased to save battery life. To increase display
●
brightness, press the f3 action key or reconnect the AC adapter.
Connecting the AC adapter
WARNING! To reduce the risk of electric shock or damage to the equipment:
Plug the power cord into an AC outlet that is easily accessible at all times.
Disconnect power from the computer by unplugging the power cord from the AC outlet (not by
unplugging the power cord from the computer).
If provided with a 3-pin attachment plug on the power cord, plug the cord into a grounded (earthed) 3pin outlet. Do not disable the power cord grounding pin, for example, by attaching a 2-pin adapter. The
grounding pin is an important safety feature.
To connect the computer to external AC power, follow these steps:
1. Plug the AC adapter into the power connector (1) on the computer.
2. Plug the power cord into the AC adapter (2).
3. Plug the other end of the power cord into an AC outlet (3).
Using battery power
When a charged battery is in the computer and the computer is not plugged into external power, the
computer runs on battery power. When the computer is plugged into external AC power, the computer
runs on AC power.
If the computer contains a charged battery and is running on external AC power supplied through the
AC adapter, the computer switches to battery power if the AC adapter is disconnected from the
computer.
NOTE: The display brightness is decreased to save battery life when you disconnect AC power. To
increase display brightness, use the f3 action key or reconnect the AC adapter.
18 Chapter 3 Power management
You can keep a battery in the computer or in storage, depending on how you work. Keeping the battery
in the computer whenever the computer is plugged into AC power charges the battery and also protects
your work in case of a power outage. However, a battery in the computer slowly discharges when the
computer is off and unplugged from external power.
WARNING! To reduce potential safety issues, use only the battery provided with the computer, a
replacement battery provided by HP, or a compatible battery purchased from HP.
Computer battery life varies, depending on power management settings, programs running on the
computer, display brightness, external devices connected to the computer, and other factors.

Maximizing battery discharge time
Battery discharge time varies depending on the features you use while on battery power. Maximum
discharge time gradually shortens, as the battery storage capacity naturally degrades.
Tips for maximizing battery discharge time:
Decrease the brightness on the display.
●
Remove the battery from the computer when it is not being used or charged.
●
Store the battery in a cool, dry location.

Managing low battery levels
The information in this section describes the alerts and system responses set at the factory. Some lowbattery alerts and system responses can be changed using Power Options in Windows Control Panel.
Preferences set using Power Options do not affect lights.
Identifying low battery levels
