When Removing Or Installing Memory Modules - Dell Inspiron 3800 Solution Manual

10 Safe ty Instr u ctions
• Clean the display with a soft, clean cloth and commercial window
cleaner that does not contain wax or abrasives. Apply the cleaner to the
cloth; then stroke the cloth across the display in one direction, moving
from the top of the display to the bottom. If the display contains
grease or some other contaminant, use isopropyl alcohol instead of
commercial window cleaner.
• If your computer gets wet, see page 40 for instructions. If you drop or
damage the computer, see page 41. If, after following these procedures,
you confirm that your computer is not operating properly, contact Dell
(see page 71).

When Removing or Installing Memory Modules

Before you remove or install memory modules, perform the following steps
in the sequence indicated.
NOTICE:
The only time you should ever access the inside of your computer is
when you are installing memory modules.
NOTICE: Wait 5 seconds after turning off the computer before
disconnecting an external device or removing a memory module to help prevent
possible damage to the system board.
Turn off your computer and all attached devices.
1
Disconnect your computer and external devices from their electrical
2
outlets to reduce the potential for personal injury or shock. Also,
disconnect any telephone or telecommunication lines from the
computer.
Remove the battery from the battery bay and, if present, the secondary
3
battery from the media bay.
Ground yourself by touching an unpainted metal surface at the back of
4
the computer before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the
computer to dissipate any static electricity that might harm internal
components.
In addition, take note of these safety guidelines when appropriate:
• When you disconnect a cable, pull on its connector, not on the cable
itself. As you pull connectors apart, keep them evenly aligned to avoid
bending any pins. Also, before you connect a cable, make sure that
both connectors are correctly oriented and aligned.
