DC IN indicator
Check the DC IN indicator to determine the power status with the AC
adaptor connected - the following indicator conditions should be noted:
Flashing orange The battery charge is low, the AC adaptor must be
connected in order to recharge the battery.

If the battery pack becomes too hot while it is being charged, the charge
will stop and the Battery indicator will go out. When the battery pack’s
temperature falls to a normal range, charging will resume - this process will
occur regardless of whether the computer’s power is on or off.

correctly supplying power to the computer.
Flashing orange Indicates a problem with the power supply. You
should initially try plugging the AC adaptor into
another power outlet - if it still does not operate
properly, you should contact your reseller or dealer.
