HP EliteOne 800 G4 - Routine Care, SATA Drive Guidelines, and Disassembly Preparation; Operating Guidelines and Routine Care

3 Routine care, SATA drive guidelines, and
disassembly preparation
This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system
board. You must disconnect the power cord from the power source before opening the computer to prevent
system board or component damage.
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 in) clearance on all vented sides of
the computer and above the monitor to permit the required airow.
●
Never restrict the airow 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 airow.
●
Never operate the computer with any of the access panels or any of the expansion card slot covers
removed.
●
Do not stack computers or place computers so near each other that they are subject to each other’s
recirculated 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 with any type of material.
●
Install or enable power management functions of the operating system or other software, including
sleep states.
●
To clean the computer, rst turn o the computer.
–
Disconnect AC power.
–
Disconnect all powered external devices.
–
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 airow.
–
In addition to the standard care guidelines, to clean the healthcare model, use ready-to-use
cleaning wipes that contain any of the following chemical solutions. Start with the display and
nish with any exible cables. Allow the computer to air-dry before use.
IMPORTANT: Spray the cleaner onto a cloth and use the damp cloth to gently wipe the screen
surface. Never spray the cleaner directly on the screen surface. It may run behind the bezel and
damage the electronics.
