The battery pack is the internal power source for the computer. It is rechargeable using the AC adapter. The operating time of a fully charged battery pack depends on how you are using the computer. When your applications often access peripherals or require intense system resources, you will experience a shorter operating time.

Charging the Battery Pack

To charge the battery pack, connect the AC adapter to the computer and an electrical outlet. The Battery Charge Indicator ( ) on the computer glows amber to indicate that charging is in progress. When the battery is fully charged, the Battery Charge Indicator glows green.

It takes approximately 2 hours to fully charge the Li-Ion battery pack when the computer is off, and 4 hours to fully charge the Li-Ion battery pack when the computer is on.

NOTES:

• Charging will not start if the battery's temperature is below 0C (32F) or above 45C (113F).
• The charging process will stop and the Battery Charge Indicator flashes amber when the battery's temperature gets above 60C (140F). If this happens, the battery pack may be damaged. Please contact your dealer.
• During charging, do not disconnect the AC adapter before the battery has been fully charged; otherwise you will get a prematurely charged battery.
• The battery level may automatically lessen due to the self-discharge process (0.21 % per day), even when the battery pack is fully charged (100 %). This happens no matter if the battery pack is installed in the computer.

CAUTION:

• After the computer has been fully recharged, do not immediately disconnect and reconnect the AC adapter to charge it again. Doing so may damage the battery.

Replacing the Battery Pack

If you often rely on battery power for a long period of time while traveling, you may consider the purchase of an additional battery pack from your dealer and keep it with you in a fully charged state as a backup.

To replace the battery pack, follow these steps:

1. Make sure that the computer is not turned on or connected to AC power.
2. Slide both battery release latches outward to the unlock position (1) and slide the battery pack away from the notebook. (2).

3. Line up the new battery for insertion into the battery bay channel.
4. Gently slide the battery pack towards the center of the unit until an audible click indicates that the latches have been secured in the lock position.

CAUTION:

• There is danger of explosion if the battery is incorrectly replaced. Replace the battery only with the computer manufacturer's optional battery packs. Discard used batteries according to the dealer's instructions.
• Do not attempt to disassemble the battery pack

Checking the Battery Level

You can check the approximate battery level using the battery meter function of the operating system. To read the battery level in Windows, click the icon on the taskbar. (Click the AC icon if the computer is using AC power.)

NOTE: .

• Any battery level indication is an estimated result. The actual operating time can be different from the estimated time, depending on how you are using the computer.
