							6 Managing power
Your computer can operate on either battery power or external power. When the computer is only
running on battery power and an AC power source is not available to charge the battery, it is
important to monitor and conserve the battery charge. Your computer supports power plans to
manage how your computer uses and conserves power so that you can balance computer
performance with power conservation.
Initiating Sleep and Hibernation
Microsoft® Windows has two power-saving states, Sleep and Hibernation.
●Sleep—The Sleep state is automatically initiated after a period of inactivity when running on
battery power or on external power. Your work is saved to memory, allowing you to resume your
work very quickly. You can also initiate Sleep manually. For more information, see 
Initiating and
exiting Sleep on page 36.
●Hibernation—The Hibernation state is automatically initiated if the battery reaches a critical level.
In the Hibernation state, your work is saved to a hibernation file and the computer powers down.
NOTE:If you want to initiate Hibernation manually, you must enable Hibernation using Power
Options. For more information, see 
Enabling and exiting user-initiated hibernation on page 36.
CAUTION:To reduce the risk of possible audio and video degradation, loss of audio or video
playback functionality, or loss of information, do not initiate Sleep 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.
Intel Rapid Start Technology (select models only)
For select models, the Intel Rapid Start Technology (RST) feature is enabled by default. Rapid Start
Technology allows your computer to resume quickly from inactivity.
Rapid Start Technology manages your power-saving options as follows:
●Sleep—Rapid Start Technology allows you to select the Sleep state. To exit from Sleep, press
any key, activate the TouchPad, or press the power button briefly.
●Hibernation—Rapid Start Technology initiates Hibernation after a period of inactivity while in the
Sleep state when running on battery power or on external power or when the battery reaches a
critical level. After Hibernation is initiated, press the power button to resume your work.
NOTE:Rapid Start Technology can be disabled in Setup Utility (BIOS). If you want to be able to
initiate the Hibernation state, you must enable user-initiated Hibernation using Power Options. See
Enabling and exiting user-initiated hibernation on page 36.

Using the power meter and power settings
The power meter is located on the Windows desktop. The power meter allows you to quickly access
power settings and view the remaining battery charge.
●To reveal the percentage of remaining battery charge and the current power plan, on the
Windows desktop, point over the power meter icon.

item from the list. From the Start screen, you can also type power, select Settings, and then
select Power Options.
Different power meter icons indicate whether the computer is running on battery or external power.
The icon also reveals a message if the battery has reached a low or critical battery level.
Running on 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. If the computer has a charged battery installed and the AC adapter
is disconnected from the computer, the computer automatically switches to battery power and the
display brightness decreases to conserve battery life. The battery in the computer slowly discharges
when the computer is off and unplugged from external power.
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.
Removing a user-replaceable battery
WARNING!To reduce potential safety issues, use only the user-replaceable battery provided with
the computer, a replacement battery provided by HP, or a compatible battery purchased from HP.
CAUTION:Removing a user-replaceable battery that is the sole power source for the computer can
cause loss of information. To prevent loss of information, save your work or shut down the computer
through Windows before removing the battery.
1.Turn the computer upside down on a flat surface.
2.Slide the battery release latch (1) to release the battery.
NOTE:The battery release latch automatically returns to its original position.
Using the power meter and power settings 37 
						

							3.Pivot the battery (2) upward and remove it from the computer (3).

an external hard drive connected to a USB port.
●Stop, disable, or remove any external media cards that you are not using.
●Before you leave your work, initiate Sleep or shut down the computer.
Identifying low battery levels
When a battery that is the sole power source for the computer reaches a low or critical battery level,
the following behavior occurs:
●The battery light (select models only) indicates a low or critical battery level.
– or –
●The power meter icon on the Windows desktop shows a low or critical battery notification.
NOTE:For additional information about the power meter, see Using the power meter and
power settings on page 37.
38 Chapter 6   Managing power 
						

							The computer takes the following actions for a critical battery level:
●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.
●If Hibernation is enabled and the computer is on or in the Sleep state, the computer initiates
Hibernation.
Resolving a low battery level
Resolving a low battery level when external power is available
●Connect an AC adapter.
●Connect an optional power adapter purchased as an accessory from HP.
Resolving a low battery level when no power source is available
Save your work and shut down the computer.
Resolving a low battery level when the computer cannot exit Hibernation
When the computer lacks sufficient power to exit Hibernation, follow these steps:
1.Replace the discharged user-replaceable battery with a charged battery, or connect the AC
adapter to the computer and to external power.
2.Exit Hibernation by pressing the power button.
Storing a user-replaceable battery
CAUTION:To reduce the risk of damage to a battery, do not expose it to high temperatures for
extended periods of time.
If a computer will be unused and unplugged from external power for more than 2 weeks, remove the
battery and store it separately in a cool, dry place to prolong the battery charge.
A stored battery should be checked every 6 months. If the capacity is less than 50 percent, recharge
the battery before returning it to storage.
