Panasonic CF-W8 Problems with Battery

Troubleshooting (Advanced)

The battery indicator lights red

zThe remaining battery power is very low (the charge is approx. 9% or less).

Connect the AC adaptor. You can use the computer when the battery indicator light is orange. If you do not have an AC

adaptor, save your data and power off your computer. After replacing the battery pack with a fully charged one, turn your

computer on again.

The battery indicator is blinking

zIf blinking red:

Quickly save your data and power off your computer. Remove the battery pack and disconnect the AC adaptor, then con-

nect them again. If the problem persists, contact your technical support office. The battery pack or charging circuit may be

defective.

zIf blinking orange:

• Battery cannot be recharged temporarily because the internal temperature of the battery pack is outside the acceptable

temperature range for recharging. Your computer can be used normally in this state. Once the range requirement is

satisfied, charging begins automatically.

• Software applications and peripheral devices (USB devices, etc.) are consuming too much power. Exit the software

applications currently running, and remove all peripherals. Once the range requirement is satisfied, charging begins

automatically.

The battery indicator is flashing

zThe battery is recharging.

If [Battery Charging Indicator] in [Main] menu of the Setup Utility is set to [Flashing], the indicator will alternately become

lighter and darker.

To increase the lifetime of the battery

zYou can prevent deterioration of the battery pack and extend the lifetime of the battery by setting Economy Mode (ECO) to

“Enabled” in the Economy Mode (ECO) setting utility. (Î page 30)

However, when Economy Mode (ECO) is set to “Enable”, the battery pack stops charging at 80% of fully charged, so the

battery operation time is shorter.

To enable/disable the Economy Mode (ECO), refer to “Switching the Economy Mode (ECO)”. (Î page 31)
