							8 Maintaining your computer
It is important to perform regular maintenance to keep your computer in optimal condition. Your
computer is an important tool for work, research, entertainment, and connecting to people. This
chapter provides information on improving the performance of your computer by running tools such
as Disk Defragmenter and Disk Cleanup and by replacing a hard drive or adding memory. It also
provides information on updating your programs and drivers, instructions for cleaning your computer,
and tips for travelling with your computer.

							Improving performance
Everyone wants a fast computer and by performing regular maintenance tasks, using tools such as
Disk Defragmenter and Disk Cleanup, as well as installing larger drives and adding more memory,
you can drastically improve the performance of your computer.
Handling drives
Observe these precautions when handling drives:
●Before removing or installing 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.
●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.
●Do not use excessive force when inserting a drive into a drive bay.
●When the battery is the only source of power, be sure that the battery is sufficiently charged
before writing to media.
●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. Airport conveyer belts and similar security devices
that check carry-on baggage use X-rays instead of magnetism and do not damage drives.
●Remove media from a drive before removing the drive from the drive bay, or traveling with,
shipping, or storing a drive.
●Do not type on the keyboard or move the computer while an optical drive is writing to a disc. The
write process is sensitive to vibration.
●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.

							Replacing a hard drive
CAUTION:Drives are fragile computer components that must be handled with care. Do not drop a
drive, place items on it, or expose it to liquids, or temperature or humidity extremes. See 
Handling
drives on page 55 for specific precautions when handling drives.
CAUTION:To prevent information loss or an unresponsive system:
Before removing or installing 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.
1.Save your work and shut down the computer.
2.Disconnect all external devices connected to the computer.
3.Unplug the power cord from the AC outlet.
4.Turn the computer upside down on a flat surface.
5.Remove the battery from the computer.
For more information, see 
Removing a user-replaceable battery on page 41.
Remove the hard drive:
1.Slide the battery release latch (1) until the service door is released, slide the door out of the slot
(2), and then lift up and remove the door (3).
56 Chapter 8   Maintaining your computer 
						

							2.Using the cable tab (1), carefully lift up and disconnect the hard drive cable from the computer,
and then pull the cable out from the routing clips (2).
3.Using a small Phillips screwdriver, remove the 2 hard drive mounting screws (1), and
corresponding screw mounting hardware (2). Using the tab (3), lift and remove the hard drive
assembly from the bay.
NOTE:After removing the hard drive from the computer, you must remove the hard drive
bracket to access the hard drive itself.
4.Spread the soft-molded hard drive bracket (1) and remove the hard drive (2).

							5.Disconnect the hard drive cable adapter (3) from the hard drive.
To install a hard drive, reverse this procedure.
Using HP 3D DriveGuard (select models only)
HP 3D DriveGuard protects a hard drive by parking the drive and halting data 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 3D DriveGuard returns the hard drive to normal
operation.
NOTE:Because solid-state drives (SSD) lack moving parts, HP 3D DriveGuard is unnecessary.
NOTE:Hard drives in the primary hard drive bay or in the secondary hard drive bay are protected
by HP 3D DriveGuard. Hard drives connected to USB ports are not covered by HP 3D DriveGuard.
For more information, see the HP 3D DriveGuard software Help.
58 Chapter 8   Maintaining your computer 
						

							Using Disk Defragmenter
As you use your computer over time, the files on the hard drive become fragmented. A fragmented
drive means data on your drive is not contiguous (sequential) and, because of this, the hard drive
works harder to locate files, thus slowing down the computer. Disk Defragmenter consolidates (or
physically reorganizes) the fragmented files and folders on the hard drive so that the system can run
more efficiently.
NOTE:It is not necessary to run Disk Defragmenter on solid-state drives.
After you start Disk Defragmenter, it works without supervision. However, depending on the size of
your hard drive and the number of fragmented files, Disk Defragmenter may take more than an hour
to complete.
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.Connect the computer to AC power.
2.Select Start > All Programs > Accessories > System Tools > Disk Defragmenter.
3.Follow the on-screen instructions.
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 run more efficiently.
To run Disk Cleanup:
1.Select Start > All Programs > Accessories > System Tools > Disk Cleanup.
2.Follow the on-screen instructions.

							Adding or replacing memory modules
Adding memory can help improve your computers performance. Your computer is like your physical
work area. The hard drive is the filing cabinet where you store your work and the memory is the desk
where you work. When your memory isn’t big enough to hold all your work easily, like a desk
overflowing with work, your productivity slows down. A great solution to improve performance is to
expand the amount of memory you have in your computer.
The computer has two memory module slots. The memory module slots are located on the bottom of
the computer under the service door. The memory capacity of the computer can be upgraded by
adding a memory module or replacing the existing memory module in one of the memory module
slots.
WARNING!To reduce the risk of electric shock and damage to the equipment, unplug the power
cord and remove all batteries before installing a memory module.
CAUTION:Electrostatic discharge (ESD) can damage electronic components. Before beginning
any procedure, ensure that you are discharged of static electricity by touching a grounded metal
object.
NOTE:To use a dual-channel configuration with a second memory module, be sure that both
memory modules are identical.
To add or replace a memory module:
CAUTION:To prevent information loss or an unresponsive system:
Shut down the computer before adding or replacing memory modules. Do not remove a memory
module while the computer is on, in the Sleep state, or in Hibernation.
If you are not sure whether the computer is off or in Hibernation, turn the computer on by pressing the
power button. Then shut down the computer through the operating system.
1.Save your work and shut down the computer.
2.Disconnect all external devices connected to the computer.
3.Unplug the power cord from the AC outlet.
4.Turn the computer upside down on a flat surface.
5.Remove the battery from the computer.
6.Remove the service door from the computer.
7.If you are replacing a memory module, remove the existing memory module:
a.Pull away the retention clips (1) on each side of the memory module.
The memory module tilts up.
