Storing a battery
CAUTION:To prevent 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.
To prolong the charge of a stored battery, place it in a cool, dry place.
NOTE: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.
Calibrate a battery before using it if it has been stored for 1 month or more.
Disposing of a used battery
WARNING!To reduce the risk of fire or burns, do not disassemble, crush, or puncture a battery;
short the external contacts on a battery; or dispose of a battery in fire or water. Do not expose a
battery to temperatures above 60˚C (140˚F). Replace the battery only with a battery approved for this
computer.
Refer to the Regulatory, Safety and Environmental Notices for battery disposal information.
Replacing the battery
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.
Battery Check notifies you to replace the battery when an internal cell is not charging properly, or
when the battery storage capacity has reached a “weak” condition. A message refers you to the
HP Web site for more information about ordering a replacement battery. If the battery is possibly
covered by an HP warranty, instructions include a warranty ID.
NOTE:To ensure that you always have battery power when you need it, HP recommends
purchasing a new battery when the storage capacity indicator turns green-yellow.
Switching between graphics modes (select models only)
The computer is equipped with switchable graphics and has two modes for processing graphics.
When switching from AC power to battery power, the computer switches from high-performance
Switching between graphics modes (select models only) 61 
						

							mode to power-saving mode to conserve battery life. Similarly, when switching from battery power to
AC power, the computer switches back to the high-performance mode.
NOTE:In order to optimize computer performance, the system might not allow switching modes, or
prompt you to switch modes. It might be necessary to close all programs before switching.
NOTE:HDMI only works in the high-performance mode. HDMI cannot be used in power-saving
mode.
When switching between AC and battery power, you are notified that the computer is about to switch
graphics modes. If you prefer, choose to continue using the same graphics mode. While the computer
switches modes, the screen goes blank for a few seconds. When the switch is complete, a notification
appears in the notification area, and the screen image reappears.
NOTE:When select computer models are in slate mode, the screen orientations are reset when
switching between graphics modes.
To determine which graphics mode you are using, right-click on the Windows desktop, and then click
Configure Switchable Graphics or Configure ATI PowerXpress™.
Shutting down the computer
CAUTION:Unsaved information will be lost when the computer is shut down.
The Shut down command closes all open programs, including the operating system, and then turns
off the display and computer.

							6Drives
Identifying installed drives
Your computer includes a solid state drive (SSD) with solid-state memory. Because it has no moving
parts, an SSD does not generate as much heat as other hard drives.
To view the drives installed on the computer, select Start > Computer.
Handling drives
Drives are fragile computer components that must be handled with care. Refer to the following
cautions before handling drives. Additional cautions are included with the procedures to which they
apply.
CAUTION:To reduce the risk of damage to the computer, damage to a drive, or loss of information,
observe these precautions:
Before you move a computer that is connected to an external hard drive, initiate Sleep and allow the
screen to clear, or properly disconnect the external hard drive.
Before handling a drive, discharge static electricity by touching the unpainted metal surface of the
drive.
Do not touch the connector pins on a removable drive or on the computer.
Handle a drive carefully; do not drop a drive or place items on it.
Before removing or inserting a drive, shut down the computer. If you are unsure whether the
computer is off, in the Sleep state, or in Hibernation, turn the computer on, and then shut it down
through the operating system.
Do not use excessive force when inserting a drive into a drive bay.
Do not type on the keyboard or move the computer while the optical drive (select models only) is
writing to a disc. The write process is sensitive to vibration.
When the battery is the only source of power, be sure that the battery is sufficiently charged before
writing to media.
Avoid exposing a drive to temperature or humidity extremes.
Avoid exposing a drive to liquids. Do not spray the drive with cleaning products.
Remove media from a drive before removing the drive from the drive bay, or traveling with, shipping,
or storing a drive.
If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective
packaging and label the package “FRAGILE.”
Avoid exposing a drive to magnetic fields. Security devices with magnetic fields include airport walk-
through devices and security wands. The airport security devices that check carry-on luggage, such
as conveyor belts, use X-rays instead of magnetism and will not damage a drive.

							Improving hard drive performance
Using Disk Defragmenter
As you use the computer, files on the hard drive become fragmented. Disk Defragmenter
consolidates the fragmented files and folders on the hard drive so that the system can run more
efficiently.
After you start Disk Defragmenter, it works without supervision. Depending on the size of your hard
drive and the number of fragmented files, Disk Defragmenter may take more than an hour to
complete. You may want to set it to run during the night or another time when you do not need access
to your computer.
HP recommends defragmenting your hard drive at least once a month. You may set Disk
Defragmenter to run on a monthly schedule, but you can defragment your computer manually at any
time.
To run Disk Defragmenter:
1.Select Start > All Programs > Accessories > System Tools > Disk Defragmenter.
2.Click Defragment now.
NOTE:Windows includes the User Account Control feature to improve the security of your
computer. You may be prompted for your permission or password for tasks such as installing
software, running utilities, or changing Windows settings. Refer to Windows Help and Support
for more information.
For additional information, access the Disk Defragmenter software Help.
Using Disk Cleanup
Disk Cleanup searches the hard drive for unnecessary files that you can safely delete to free up disk
space and help the computer to run more efficiently.
To run Disk Cleanup:
1.Select Start > All Programs > Accessories > System Tools > Disk Cleanup.
2.Follow the on-screen instructions.
Using HP ProtectSmart Hard Drive Protection
HP ProtectSmart Hard Drive Protection protects the hard drive by parking the drive and halting I/O
requests under either of the following conditions:
●You drop the computer.
●You move the computer with the display closed while the computer is running on battery power.
A short time after the end of one of these events, HP ProtectSmart Hard Drive Protection returns the
hard drive to normal operation.
NOTE:Because solid-state drives (SSDs) lack moving parts, HP ProtectSmart Hard Drive
Protection is unnecessary.
NOTE:Hard drives connected to USB ports are not protected by HP ProtectSmart Hard Drive
Protection.
For more information, refer to the HP ProtectSmart Hard Drive Protection software Help.
