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 day or two. Intense heat can shorten battery life.

■Do not leave a battery in storage for longer than 6 months without recharging it.

Increasing Battery Life

■Keep brightness to the lowest level comfortable.

■Set the power management for maximum battery life.

■Put your notebook in Standby mode when it is turned on and you are not actually using it.

■Limit your CD-ROM access.

■Disable the Windows CD auto insert function.
