							7 Maintaining your computer
It is important to perform regular maintenance to keep your computer in optimal condition. This
chapter explains how to use tools like Disk Defragmenter and Disk Cleanup. It also provides
instructions for updating programs and drivers, steps to clean the computer, and tips for traveling with
(or shipping) the computer.
Improving performance
You can improve the performance of your computer by performing regular maintenance tasks with
tools such as Disk Defragmenter and Disk Cleanup.
Using Disk Defragmenter
HP recommends using Disk Defragmenter to defragment your hard drive at least once a month.
NOTE:It is not necessary to run Disk Defragmenter on solid-state drives.
To run Disk Defragmenter:
1.Connect the computer to AC power.
2.From the Start screen, type defragment, and then select Defragment and optimize your drives.
3.Follow the on-screen instructions.
For additional information, access the Disk Defragmenter software Help.
Using Disk Cleanup
Use Disk Cleanup to search 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.From the Start screen, type disk, and then select one of the following:
●Free up disk space on this PC
●Uninstall apps to free up disk space
●Free up disk space by deleting uncessary files
2.Follow the on-screen instructions.
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.
Improving performance 37 
						

							NOTE:Because solid state drives (SSDs) lack moving parts, HP 3D DriveGuard is unnecessary.
NOTE:A hard drive in a primary hard drive bay or a secondary hard drive bay is protected by HP
3D DriveGuard. A hard drive installed in an optional docking device or connected to a USB port is not
protected by HP 3D DriveGuard.
For more information, see the HP 3D DriveGuard software Help.
Identifying HP 3D DriveGuard status
The hard drive light on the computer changes color to show that the drive is parked. To determine
whether the drive is currently protected or whether it is parked, view the icon on the Windows desktop
in the notification area, at the far right of the taskbar, or in the Mobility Center.
Updating programs and drivers
HP recommends that you update your programs and drivers on a regular basis. Updates can resolve
issues and bring new features and options to your computer. For example, older graphics
components might not work well with the most recent gaming software. Without the latest driver, you
would not be getting the most out of your equipment.
Go to 
http://www.hp.com/support to download the latest versions of HP programs and drivers. In
addition, register to receive automatic notifications when updates become available.
If you would like to update your programs and drivers, follow these instructions:
1.From the Start screen, type support, and then select the HP Support Assistant app.
-or-
From the Windows desktop, click the question mark icon in the taskbar area of the Windows
desktop.
2.Click Updates and tune-ups, and then click Check for HP updates now.
3.Follow the on-screen instructions.
Cleaning your computer
Use the following products to safely clean your computer:
●Dimethyl benzyl ammonium chloride 0.3 percent maximum concentration (for example,
disposable wipes, which come in a variety of brands)
●Alcohol-free glass-cleaning fluid
●Solution of water and mild soap
●Dry microfiber cleaning cloth or a chamois (static-free cloth without oil)
●Static-free cloth wipes
CAUTION:Avoid strong cleaning solvents that can permanently damage your computer. If you are
not sure that a cleaning product is safe for your computer, check the product contents to make sure
that ingredients such as alcohol, acetone, ammonium chloride, methylene chloride, and hydrocarbons
are not included in the product.
Fibrous materials, such as paper towels, can scratch the computer. Over time, dirt particles and
cleaning agents can get trapped in the scratches.
38 Chapter 7   Maintaining your computer 
						

							Cleaning procedures
Follow the procedures in this section to safely clean your computer.
WARNING!To prevent electric shock or damage to components, do not attempt to clean your
computer while it is on.
1.Turn off the computer.
2.Disconnect AC power.
3.Disconnect all powered external devices.
CAUTION:To prevent damage to internal components, do not spray cleaning agents or liquids
directly on any computer surface. Liquids dripped on the surface can permanently damage internal
components.
Cleaning the display
Gently wipe the display using a soft, lint-free cloth moistened with an alcohol-free glass cleaner. Be
sure that a display is dry before you close the computer.
Cleaning the sides or cover
To clean the sides or cover, use a soft microfiber cloth or chamois moistened with one of the cleaning
solutions listed previously, or use an acceptable disposable wipe.
NOTE:When cleaning the cover of the computer, use a circular motion to aid in removing dirt and
debris.
Cleaning the TouchPad, keyboard, or mouse (select models only)
WARNING!To reduce the risk of electric shock or damage to internal components, do not use a
vacuum cleaner attachment to clean the keyboard. A vacuum cleaner can deposit household debris
on the keyboard surface.
CAUTION:To prevent damage to internal components, do not allow liquids to drip between the
keys.
●To clean the TouchPad, keyboard, or mouse, use a soft microfiber cloth or a chamois moistened
with one of the cleaning solutions listed previously or use an acceptable disposable wipe.
●To prevent keys from sticking and to remove dust, lint, and particles from the keyboard, use a
can of compressed air with a straw extension.
Traveling with or shipping your computer
If you have to travel with or ship your computer, follow these tips to keep your equipment safe.
●Prepare the computer for traveling or shipping:
◦Back up your information to an external drive.
◦Remove all discs and all external media cards, such as memory cards.
◦Turn off and then disconnect all external devices.
◦Shut down the computer.
●Take along a backup of your information. Keep the backup separate from the computer.
Traveling with or shipping your computer 39 
						

							●When traveling by air, carry the computer as hand luggage; do not check it in with the rest of
your luggage.
CAUTION: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.
●If you plan to use the computer during a flight, listen for the in-flight announcement that tells you
when you are allowed to use your computer. In-flight computer use is at the discretion of the
airline.
●If you are shipping the computer or a drive, use suitable protective packaging and label the
package “FRAGILE.”
●The use of wireless devices may be restricted in some environments. Such restrictions may
apply aboard aircraft, in hospitals, near explosives, and in hazardous locations. If you are
uncertain of the policy that applies to the use of a wireless device in your computer, ask for
authorization to use your computer before you turn it on.
●If you are traveling internationally, follow these suggestions:
◦Check the computer-related customs regulations for each country or region on your
itinerary.
◦Check the power cord and adapter requirements for each location in which you plan to use
the computer. Voltage, frequency, and plug configurations vary.
WARNING!To reduce the risk of electric shock, fire, or damage to the equipment, do not
attempt to power the computer with a voltage converter kit sold for appliances.
