Problems with Battery
z
The battery level 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.
z
If blinking red:
Quickly save your data and power off your computer. Remove the battery pack and dis-
connect the AC adaptor, then connect them again. If the problem persists, contact your
technical support office. The battery pack or charging circuit may be defective.
z
If 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. Once the range
requirement is satisfied, charging begins automatically.
z
The 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.
z
You can prevent deterioration of the battery pack and extend the lifetime of the battery by
setting Economy Mode (ECO) to "Enable" in the Economy Mode (ECO) setting utility.
(
) Note, however, that enabling this function will reduce the battery operating
time even when the battery is fully charged.
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)". (
