4.20 Auxiliary Power Connector
An auxiliary power connector is available to power some interfaces when the input power is
not in the 11V to 13V range and the power at 12V PCIe, VCC_LCD (X1601), VCC_BL_EDP
(X1602), VCC_BL (X1101) and 12V fan power are switched-off. In that case, you can feed
12V from an external power source at X1603 pin 4 to supply these connectors with power.
The drawn current depends on the connected devices.
12V output and 5V can power a harddisk.
