Using power-saving states
The computer has two power-saving states enabled at the factory: Sleep and Hibernation.
When Sleep is initiated, the power light blinks and the screen clears. Your work is saved to memory,
letting you exit Sleep faster than exiting Hibernation. If the computer is in the Sleep state for an extended
period or if the battery reaches a critical battery level while in the Sleep state, 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 Sleep or Hibernation while reading from or writing to
a disc or an external media card.
NOTE: You cannot initiate any type of networking connection or perform any computer functions while
the computer is in the Sleep state or in Hibernation.
Initiating and exiting Sleep
The system is set at the factory to initiate Sleep after 15 minutes of inactivity when running on battery

Testing an AC adapter
Test the AC adapter if the computer exhibits any of the following symptoms:
The computer will not turn on when connected to the AC adapter.
●
The display does not turn on when the computer is connected to the AC adapter.
●
The power light is off when the computer is connected to the AC adapter.
●
To test the AC adapter:
1. Remove the battery from the computer.
2. Connect the AC adapter.
3. Turn on the computer.
If the power light turns on, the AC adapter is functioning properly.
●
If the power light remains off, the AC adapter is not functioning and should be replaced.
●
Contact technical support for information on obtaining a replacement AC power adapter. Select

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 f4 key or reconnect the AC adapter.
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.

Charging a battery
WARNING! Do not charge the computer battery while you are onboard aircraft.
The battery charges whenever the computer is plugged into external power through an AC adapter, an
optional power adapter, an optional expansion product, or an optional docking device.
The battery charges whether the computer is off or in use, but it charges faster when the computer is
off.
Charging may take longer if a battery is new, has been unused for 2 weeks or more, or is much warmer
or cooler than room temperature.
To prolong battery life and optimize the accuracy of battery charge displays, follow these
recommendations:
If you are charging a new battery, charge it fully before turning on the computer.
●
Charge the battery until the battery light turns off.
●
NOTE: If the computer is on while the battery is charging, the battery meter in the notification
area may show 100 percent charge before the battery is fully charged.
Allow the battery to discharge below 5 percent of a full charge through normal use before charging
●
it.
If the battery has been unused for one month or more, calibrate the battery instead of simply
●
charging it.
The battery light displays charge status:
On: The battery is charging.
●
Blinking: The battery has reached a low battery level or critical battery level and is not charging.
●
Off: The battery is fully charged, in use, or not installed.
●

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:
Lower the brightness on the display.
●
Select the Power saver setting in Power Options.
●
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
(Start > Control Panel > System and Security > Power options). Preferences set using Power
Options do not affect lights.
Identifying low battery levels
When a battery that is the sole power source for the computer reaches a low battery level, the battery
light blinks.
If a low battery level is not resolved, the computer enters a critical battery level, and the battery light
blinks rapidly.
The computer takes the following actions for a critical battery level:
If Hibernation is enabled and the computer is on or in the Sleep state, the computer initiates
●
Hibernation.
If Hibernation is disabled and the computer is on or in the Sleep state, the computer remains briefly
●
in the Sleep state, and then shuts down and loses any unsaved information.
