7-4 Caring for the Computer
Cleaning Guidelines
Never clean the computer with its power on.
Use a soft cloth moistened with water or a non-alkaline detergent to
wipe the exterior of the computer.
Gently wipe the display with a soft, lint-free cloth. Do not use alcohol
or detergent on the display.
Dust on the IR/Bluetooth port can interfere with data transfer. Wipe
the port with a soft, dry cloth.
Dust or grease on the touchscreen can affect its sensitivity. Clean the
touchscreen by using adhesive tape to remove the dust and grease on
its surface.
Battery Pack Guidelines
Recharge the battery pack when it is nearly discharged. When
recharging, make sure the battery pack is fully charged. Doing so
may avoid harm to the battery pack.
Operate the computer with the battery pack installed even when using
external power. This ensures that the battery is fully charged.
If you will not be using the computer for a long period of time (more
than two weeks), remove the battery pack from the computer.
If you remove the battery pack, make sure the battery terminals do
not contact any conductors such as metal objects or water. Otherwise,
the battery may become unusable as a result of a short circuit.
If you need to store the battery pack, store it in a cool, dry place.
Never allow the temperature to exceed 70 °C (158 °F).
Do not leave the battery pack in storage for more than 3 months
without recharging it.
