HP Pavilion Dm4 3000 Entertainment Notebook Pc Series Manual

							B Cleaning your computer
Cleaning the display
Gently wipe the display using a soft, lint-free cloth moistened with an alcohol-free glass cleaner. Be
sure that the display is dry before closing the display.
Cleaning the sides and cover
To clean and disinfect the sides and cover, use a soft microfiber cloth or a static-free cloth without oil
(such as a chamois) moistened with an alcohol-free glass cleaner or use an acceptable germicidal
disposable wipe.
NOTE:When cleaning the cover of the computer, use a circular motion to aid in removing dirt and
debris.
Cleaning the TouchPad and keyboard
CAUTION:When cleaning the TouchPad and keyboard, do not let liquids drip between the keys.
This can permanently damage internal components.
●To clean and disinfect the TouchPad and keyboard, use a soft microfiber cloth or a static-free
cloth without oil (such as a chamois) moistened with an alcohol-free glass cleaner or use an
acceptable germicidal 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.
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.

							C Traveling with the computer
For best results, follow these traveling and shipping tips:
●Prepare the computer for traveling or shipping:
◦Back up your information.
◦Remove all discs and all external media cards, such as digital cards.
CAUTION:To reduce the risk of damage to the computer, damage to a drive, or loss of
information, remove the media from a drive before removing the drive from a drive bay and
before shipping, storing, or traveling with a drive.
◦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.
●When traveling by air, carry the computer as hand luggage; do not check it in with the rest of
your bags.
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.
●In-flight computer use is at the discretion of the airline. If you plan to use the computer during a
flight, check with the airline in advance.
●If the computer will be unused and disconnected from external power for more than 2 weeks,
remove the battery and store it separately.
●If you are shipping the computer or a drive, use suitable protective packaging and label the
package “FRAGILE.”
●If the computer has a wireless device or an HP Mobile Broadband Module installed, such as an
802.11b/g device, a Global System for Mobile Communications (GSM) device, or a General
Packet Radio Service (GPRS) device, the use of these devices may be restricted in some
environments. Such restrictions may apply onboard aircraft, in hospitals, near explosives, and in
102 Appendix C   Traveling with the computer 
						

							hazardous locations. If you are uncertain of the policy that applies to the use of a particular
device, ask for authorization to use it 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.

							E Electrostatic Discharge
Electrostatic discharge is the release of static electricity when two objects come into contact—for
example, the shock you receive when you walk across the carpet and touch a metal door knob.
A discharge of static electricity from fingers or other electrostatic conductors may damage electronic
components. To prevent damage to the computer, damage to a drive, or loss of information, observe
these precautions:
●If removal or installation instructions direct you to unplug the computer, unplug it after being
properly grounded and before removing a cover.
●Keep components in their electrostatic-safe containers until you are ready to install them.
●Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
●Use nonmagnetic tools.
●Before handling components, discharge static electricity by touching an unpainted metal surface
of the component.
●If you remove a component, place it in an electrostatic-safe container.
If you need more information about static electricity or assistance with component removal or
installation, contact customer support.
