Care and use of the battery pack
Safety precautions
1. Turn off the computer’s power immediately and disconnect the power cord
from the power socket, if the battery pack produces an odor, overheats or
changes color or shape while it is being used or charged. Carefully remove the
battery pack from the computer.
2. Be very careful not to short-circuit the battery pack. Contacting both terminals
with a metal object can cause injury, fire or damage to the battery pack.
3. Do not overcharge, reverse charge, mutilate or disassemble the battery pack.
Any one of those actions could release toxic materials, hydrogen and/or
oxygen or other electrolytic substances or cause an increase in the battery
pack’s surface temperature.
4. Do not expose the battery pack to fire; the battery pack could explode.
5. Battery packs contain toxic substances. Do not dispose of them with ordinary
trash. Dispose of battery packs only in accordance with local ordinances.
Always cover the metal terminals with insulating tape to avoid short circuits.
6. If the battery pack has leaked or been vented, it should be replaced immedi-
ately. Use protective gloves when handling a damaged battery pack.
7. When it becomes necessary to replace the battery pack, it must be replaced
only by an identical battery pack from the same manufacturer.
8. Do not expose the battery pack terminals to any metal object other than the
computer contacts. Wrap it or place it in a plastic bag when transporting it.
9. When you install the battery pack, you should hear a click when it is seated
properly.
10. Charge the battery pack only in the computer or in a battery pack charger
designated as an approved option.
11. Reverse polarity should be avoided with all battery packs. The battery pack is
designed so that it cannot be installed in reverse polarity.
Charging the batteries
When the power in the battery pack becomes low, the Battery indicator flashes
orange indicating that only a few minutes of battery power remain. If you continue
to use the computer while the Battery indicator flashes, the computer enables
Resume mode (so you don’t lose data) and automatically turns off.
You must recharge a battery pack when it becomes discharged.
