Battery replacement
The battery that comes with the computer provides power to the real-time clock. When replacing the
battery, use a battery equivalent to the battery originally installed in the computer. The computer
comes with a 3-volt lithium coin cell battery.
WARNING! The computer contains an internal lithium manganese dioxide battery. There is a risk of
fire and burns if the battery is not handled properly. To reduce the risk of personal injury:
Do not attempt to recharge the battery.
Do not expose to temperatures higher than 60°C (140ºF).
Do not disassemble, crush, puncture, short external contacts, or dispose of in fire or water.
Replace the battery only with the HP spare designated for this product.
CAUTION: Before replacing the battery, it is important to back up the computer CMOS settings.
When the battery is removed or replaced, the CMOS settings will be cleared.
Static electricity can damage the electronic components of the computer or optional equipment.
Before beginning these procedures, ensure that you are discharged of static electricity by briefly
touching a grounded metal object.

Electrostatic discharge
A discharge of static electricity from a finger or other conductor may damage system boards or other
static-sensitive devices. This type of damage may reduce the life expectancy of the device.
Preventing electrostatic damage
To prevent electrostatic damage, observe the following precautions:
●
Avoid hand contact by transporting and storing products in static-safe containers.
●
Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
●
Place parts on a grounded surface before removing them from their containers.
●
Avoid touching pins, leads, or circuitry.
●
Always be properly grounded when touching a static-sensitive component or assembly.
Grounding methods
There are several methods for grounding. Use one or more of the following methods when handling
or installing electrostatic-sensitive parts:
●
Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis.
Wrist straps are flexible straps with a minimum of 1 megohm +/- 10 percent resistance in the
ground cords. To provide proper ground, wear the strap snug against the skin.
●
Use heelstraps, toestraps, or bootstraps at standing workstations. Wear the straps on both feet
when standing on conductive floors or dissipating floor mats.
●
Use conductive field service tools.
●
Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, contact an HP authorized
dealer, reseller, or service provider.
NOTE: For more information on static electricity, contact an HP authorized dealer, reseller, or
service provider.

Computer operating guidelines and routine care
Follow these guidelines to properly set up and care for the computer and monitor:
●
Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and
cold.
●
Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all
vented sides of the computer and above the monitor to permit the required airflow.
●
Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.
●
Never operate the computer with the access panel or any of the expansion card slot covers
removed.
●
Do not stack computers on top of each other or place computers so near each other that they
are subject to each other’s re-circulated or preheated air.
●
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation
must be provided on the enclosure, and the same operating guidelines listed above will still
apply.
●
Keep liquids away from the computer and keyboard.
●
Never cover the ventilation slots on the monitor with any type of material.
●
Install or enable power management functions of the operating system or other software,
including sleep states.
●
Turn off the computer before you do either of the following:
◦
Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning
products may discolor or damage the finish.
◦
Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other
foreign matter can block the vents and limit the airflow.
Computer operating guidelines and routine care
