On Using Batteries
Never leave the battery pack in temperatures above 60 C, such as in
a car parked in the sun or under direct sunlight.
Battery life is shorter in a cold environment. This is due to decreased
battery efficiency at low temperatures.
Charge the batteries at temperatures between 10 C to 30 C. Lower
temperatures require a longer charging time.
While the battery is in use or being discharged, the battery pack heats
up. This is normal and is not a cause for concern.
Keep the battery pack away from all sources of heat.
Keep the battery pack dry.
Do not open or try to disassemble the battery pack.
Do not expose the battery pack to any mechanical shock.
If you are not using the computer for an extended period of time,
remove the battery pack from the computer to prevent damage to the
battery.
If, after fully charging the battery pack, the battery power is still low,
the battery pack may be reaching the end of its life and should be
replaced.
You do not need to discharge the battery before recharging.
If you have not used the battery pack for a considerable amount of
time, recharge the battery.
On Maintenance
Make sure to disconnect the AC adapter before cleaning the
computer.
Avoid rubbing the LCD screen as this can damage the screen. Use a
soft, dry cloth to wipe the LCD screen.
Clean the computer with a soft cloth lightly moistened with a mild
detergent solution. Do not use any type of abrasive pad, scouring
powder or solvent, such as alcohol or benzine.
