Page 51: Operating Guidelines
Operating Guidelines To prevent overheating and to help prolong the life of the computer: ● 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.
Page 52: Routine Care
Routine Care General Cleaning Safety Precautions Never use solvents or flammable solutions to clean the computer. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component. Always unplug the computer when cleaning with liquids or damp cloths.
Page 53: Cleaning The Monitor
● If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets. CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard may not function properly.

Page 71 Before installing an expansion card, remove the expansion slot cover or the existing expansion card. NOTE: Before removing an installed expansion card, disconnect any cables that may be attached to the expansion card. If you are installing an expansion card in a vacant socket, you must remove the metal slot cover on the rear panel that covers the expansion slot.
Page 72 If you are removing a PCI Express x16 card, pull the retention arm on the back of the expansion socket away from the card and carefully rock the card back and forth until the connectors pull free from the socket. Be sure not to scrape the card against the other components.
Page 73 If you are not installing a new expansion card, install an expansion slot cover to close the open slot. CAUTION: After removing an expansion card, you must replace it with a new card or expansion slot cover for proper cooling of internal components during operation. To install an expansion card, locate where the card will be seated inside the computer.
Page 74 To install an expansion card, locate where the card will be seated inside the computer. Figure 7-16 Installing an expansion card — PCIe x16 Figure 7-17 Installing an expansion card — PCIe x1 Connect external cables to the installed card, if needed. Connect internal cables to the system board, if needed.
Page 75: Cable Management
Cable Management Always follow good cable management practices when working inside the computer. ● Keep cables away from major heat sources like the heat sink. ● Do not jam cables on top of expansion cards or memory modules.
