disconnecting a peripheral device from the computer, wait 5 seconds
after turning off the computer before removing the memory module or
disconnecting the device to help avoid possible damage to the system
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 or is damaged, follow the procedures
described in "If Your Computer Gets Wet" on page 42 and "If You
Drop or Damage Your Computer" on page 43. If, after following these
procedures, you confirm that your computer is not operating properly,
contact Dell (see page 73).
When Removing or Installing Memory Modules
Before removing or installing memory modules, perform the following steps
in the sequence indicated.
The only time you should ever access the inside of your computer is

Wait 5 seconds after turning off the computer before disconnecting
a peripheral device or removing a memory module to help prevent possible
damage to the system board.
Turn off your computer and any attached peripherals.
Disconnect your computer and peripherals from electrical outlets to
reduce the potential for personal injury or shock. Also, disconnect any
telephone or telecommunication lines from the computer.
Remove the main battery from the battery bay and, if necessary, the
secondary battery from the media bay.

While you work, periodically touch the I/O panel to dissipate any
static electricity that might harm internal components.
