  USB PowerShare  


On many of the new notebook systems the Default setting in the BIOS for USB PowerShare is  = Disabled.

Only the USB connector with a lightning bolt icon, as seen in the image below, can be used.


USB PowerShare Port


This functionality is enabled in the system setup under the On Board Devices heading. You can select how much of the battery's charge can be used as well (pictured below). If you set the USB PowerShare to 25%, the external device is allowed to charge until the battery reaches 25% of full capacity

(e.g. 75% of the portable's battery charge is used up).



USB PowerShare BIOS



When this option is set to Disabled, the USB PowerShare feature will be turned off and devices attached to the USB PowerShare port will not be charged when the system is off. Selecting any of the other settings enables the feature and specifies the system battery capacity at which charging of a USB device attached to the USB PowerShare port will be terminated.

The Latitude E6510 does not support the USB PowerShare feature.

At time of release the online documentation and the BIOS may show the feature as available. It is not supported on this model and the documentation and Bios will subsequently be updated to reflect this.
