Charging the Battery and Charging Time

To charge the battery, while the battery pack is in the notebook, plug the AC adapter into

the notebook and an electrical outlet.

The charging time is approximately 4-6 hours when the notebook is turned off and

approximately 6-10 hours when the notebook is turned on.

When the battery is fully charged, the battery charge indicator becomes green.

Note: If the system runs at heavy loading or in a high temperature environment, the

battery may not become fully charged. You need to continue to charge it with the AC

adapter plugged in until the charging LED turns green.

Checking the Battery Level

You can check the remaining battery power in the Windows battery status indicator, which

is located at the lower right-hand corner of the task bar. (If you do not see a battery or AC-

in icon on the task tray, go to the Power Options Properties box and click on the Advanced

tab. Check off ``Always show icon on the task bar``.)

Alternatively, you can access the power meter by clicking the Power Options icon in the

Windows Control Panel.
