KEYBOARD
Caring for your Keyboard
The keyboard of your computer is a very sensitive
instrument. It is made up of many switches that are
activated when you press on the keys. The keyboard is a
major component of the heat dissipation system in a
notebook. Due to heat and size considerations the
keyboard is not sealed. Because the keys are so close
together, it is not easy for the user to see when liquids
have fallen onto the circuitry below the keys.
When attempting to clean the keyboard with a spray-on
cleaner or rag soaked with cleaner, the liquid can drip
unseen onto the circuitry. If liquid seeps between the
layers of circuitry, it can cause corrosion or other
damage to the circuits. This can result in keys which no
longer operate, or which display the wrong characters.
There is no repair for this problem other than replace-
ment. The solution is to become aware of the issue and
take appropriate steps to protect your keyboard.
Cleaning should be done with a rag lightly dampened
with cleaning solution. Use extreme care to prevent
liquid from dripping between the keys. Spraying directly
on the keys should be avoided. The spray should first be
applied to the cloth, then the cloth wiped over the keys.
BATTERIES
Caring for your Batteries
■
Always handle batteries carefully.
■
Do not short-circuit the battery terminals (that is, do
not touch both terminals with a metal object). Do not
carry lose batteries in a pocket or purse where they
may mix with coins, keys, or other metal objects.
Doing so may cause an explosion or fire.
■
Do not drop, puncture, disassemble, mutilate or
incinerate the battery.
■
Recharge batteries only as described in this manual
and only in ventilated areas.

Do not leave batteries in hot locations for more than a

months without recharging it.
