Cleaning the Notebook Exterior

Use the steps below to clean the outer surface of the system.
1. Power off the system and remove all battery packs. Unplug all cables
connected to the system.
2. Wipe the outside of the system, keyboard, and display with a soft, clean
cloth. Remove stains with a damp, almost dry cloth. Use glass cleaner to
clean the LCD. Apply the glass cleaner directly to the cloth and then wipe
the LCD. Do not use solvents or strong, abrasive cleaners on any part of the
system.
3. Clean the keys with a damp cloth. A small, soft-bristle brush may be used to
clean between the keys. Make sure to use a damp cloth (not wet) to prevent
moisture from seeping between the keyboard and the metal plate, possibly
damaging the components under the keys. If the keyboard gets wet,
thoroughly dry it before reassembling the system unit.

particles from inside the system unit as follows:

discussed in the section, Disassembly and Reassembly, in Chapter 3.
2. Dust or vacuum (with a rubber-tipped nozzle) the inside of the system,
particularly the motherboard surface. Use care to avoid damaging or
dislodging any components or cables.
3. Inspect all cables connectors for damage. Ensure that connectors are seated
properly before replacing the cover.
