							8 Power management
Setting power options
Using power-saving states
The computer has two power-saving states enabled at the factory: Sleep and Hibernation.
When Sleep is initiated, the power lights blink 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
power and 30 minutes of inactivity when running on external power.
Power settings and timeouts can be changed using Power Options in Windows
® Control Panel.
With the computer on, you can initiate Sleep in any of the following ways:
●Press fn+f1.
●Briefly press the power button.
●Close the display.
●Select Start, click the arrow next to the Shut down button, and then click Sleep.
You can exit Sleep in any of the following ways:
●Briefly press the power button.
●If the display is closed, open the display.

66 Chapter 8   Power management 
						

							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) 3-
pin 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:
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).
Testing an AC adapter
Test the AC adapter if the computer exhibits any of the following symptoms when it is connected to AC
power:
●The computer will not turn on.
●The display does not turn on.
●The power light is off.
To test the AC adapter:
1.Remove the battery from the computer.
2.Connect the AC adapter to the computer, and then plug it into an AC outlet.
3.Turn on the computer.
If the power light turns on, the AC adapter is working properly.
Contact technical support for information on obtaining a replacement AC power adapter. Select Start
> Help and Support > Get assistance.

							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 fn+f4 hotkey 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.
Finding battery information in Help and Support
Help and Support provides the following tools and information about the battery:
●Battery Check tool to test battery performance
●Information on calibration, power management, and proper care and storage to maximize battery
life
●Information on battery types, specifications, life cycles, and capacity
To access battery information:
▲Select Start > Help and Support > Learn > Power Plans: Frequently Asked Questions.
Using Battery Check
Help and Support provides information on the status of the battery installed in the computer.
To run Battery Check:
1.Connect the AC adapter to the computer.
NOTE:The computer must be connected to external power for Battery Check to function properly.
2.Select Start > Help and Support > Troubleshoot > Power, Thermal and Mechanical.
3.Click the Power tab, and then click Battery Check.
Battery Check examines the battery and its cells to see if they are functioning properly, and then reports
the results of the examination.

loss of information, save your work and initiate Hibernation or shut down the computer through Windows
before removing the battery.
To insert the battery:
1.Turn the computer upside down on a flat surface.
2.Align the tabs on the battery with the notches on the computer (1), and then insert the battery into
the battery bay. The battery release latches (2) automatically lock the battery into place.

							2.Slide the battery release latches (1) to release the battery, and then remove the battery (2).
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, or an optional expansion product.
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 that is the only available power source has reached a low battery level. When
the battery reaches a critical battery level, the battery light begins blinking rapidly.
●Off: The battery is fully charged, in use, or not installed.
