Check Battery Charge LED Status:
If the laptop is connected to an electrical outlet, the power/battery light operates as follows:
|Power State||Charging status||LED Behavior|
|On||Any (0-100%)||Solid white|
|Standby||Any (0-100%)||Breathe white (slow increase/decrease in illumination)|
|Off, hibernate||>90% charge||Off|
|Off, hibernate||=90% charge||Solid white|
If the laptop is running on a battery, the power/battery light operates as follows:
|Power State||Remaining battery power||LED Behavior|
|On||=10% charge||Solid white|
|On||<10% charge||Solid amber|
|Standby||=10% charge||Breathe white (slow increase/decrease in illumination)|
|Standby||<10% charge||Solid amber|
|Off, hibernate||Any (0-100%)||Off|
Try running the ePSA diagnostics on the system, the range of tests includes the Primary Battery.
This tests only the primary battery in a system. The battery is tested by displaying its percentage of full charge and its overall health.
To start diagnostics:
|Error Number||Error Message||Action to be Taken|
ePSA: Battery - The battery is not installed
Install the battery;
Check for debris or damaged contacts.
To troubleshoot the battery further see article Dell Notebook PC: Battery Troubleshooting Guide.

The charge state of the battery pack is monitored and stored within registers internal to the battery pack electronics. This may be referred to as a fuel gauge. The charge status LEDs on the battery pack indicate the remaining charge in the following manner:
Portable system batteries as with all other rechargeable batteries degrade over time. The amount of time the battery will operate the device on a full charge will reduce as the battery ages. This performance loss is also based on the number of times the battery is discharged and charged. Dell portable system batteries provide a way to monitor the degradation. The degradation status will display after holding the battery check button, located on the battery pack, down for more than 3 seconds. The battery pack LEDs will then show overall battery degradation after the charge gauge reports the battery's current charge capacity. The degradation LEDs display the following:
The hinge or system battery LED can indicate many battery states. The LED can blink and change color representing the battery's current operational condition. The LED indicates the following states (click the image for a larger view in a new window):
