C A U T I O N

Do not leave a faulty battery in your notebook. It might damage your AC adapter, optional auto/airline adapter, another battery, or your notebook itself. It may also prevent operation of your notebook by draining all available current into the bad battery.

C A U T I O N

Under federal, state or local law it may be illegal to dispose of batteries by putting them in the trash. Please take care of our environment and dispose of batteries properly. Check with your local government authority for details regarding recycling or disposing of old batteries. If you cannot find this information elsewhere, contact your support representative at 1-800- 8FUJITSU (1-800-838-5487).

Shorted Batteries

If your Status Indicator panel shows a shorted battery, check the installation for that battery by removing and re-installing it. If it still shows that it is shorted, replace it with a new battery.

C A U T I O N

A shorted battery is damaged and must be replaced so that it does not damage anything else.

Recharging the Batteries

If you want to check the condition of either the main Lithium ion battery or an optional second Lithium ion battery, check the Battery Level indicators located on the Status Indicator panel. These indicators change as the battery levels change. Battery 1 is the main Lithium ion battery and Battery 2 is an optional second Lithium ion battery which is installed in Multi- function Bay 2 only. (Figure 2-3 on page 19.) You can also check the PowerPanel toolbar. (See pages 41–44.)

The Lithium ion batteries are recharged inter- nally using the AC adapter or auto/airline adapter. To recharge the batteries:

■Make sure the main battery to be charged is installed in the Battery bay and any optional second battery is installed in Multi-function Bay 2 of your notebook,then connect the AC adapter or auto/airline adapter.

■Make sure that the Battery Charging indica- tor to the left of the Battery Level indicator of the battery to be charged is visible on the Status Indicator panel.

■The percentage charge is shown inside the Battery Level icon. (Figure 2-4 on page 21.)

When two Lithium ion batteries are installed, the charge/discharge rate of the main and optional second Lithium ion batteries are the same,as they are connected in parallel and are both charging and/or discharging at the same time. Since the rates are the same, one may fin- ish charging or discharging before the other if they were not at the same charge level when
