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.

If blinking red:
Quickly save your data and power off your computer. Remove the battery
pack and disconnect the AC adaptor, then connect them again. If the prob-
lem persists, contact your technical support office. The battery pack or
charging circuit may be defective.

ture 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.
