Monitoring of power condition
As shown in the below table, the DC IN/Battery and Power indicators on the system indicator panel alert you to the computer’s operating capability and battery charge status.
DC IN/Battery indicator
Check the DC IN/Battery indicator to determine the status of the battery pack and the power status with the AC adaptor connected. The following indicator conditions should be noted:
Flashing amber | The battery charge is low, the AC adaptor |
| must be connected in order to recharge the |
| battery. |
| 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. |
|
|
Amber | Indicates the AC adaptor is connected and the |
| battery is charging. |
White | Indicates the AC adaptor is connected and the |
| battery is fully charged. |
No light | Under any other conditions, the indicator does |
| not light. |
|
|
If the battery pack becomes too hot while it is being charged, the charge will stop and the DC IN/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.
Power indicator
Check the Power indicator to determine the power status of the computer - the following indicator conditions should be noted:
White | Indicates power is being supplied to the |
| computer and the computer is turned on. |
|
|
Blinking amber | Indicates that the computer is in Sleep Mode and |
| that there is sufficient power available (AC |
| adaptor or battery) to maintain this condition. In |
| Sleep Mode, this indicator will turn on for one |
| second and off for two seconds. |
|
|
No light | Under any other conditions, the indicator does |
| not light. |
