ECN:20190828PRP01 Engineering change notice concerning red/black power cables on the Pinebook Pro mainboard. 1.The Pinebook Pro does not power on from mains (DC barrel jack or USB-C power adapter) with the Lithium battery disconnected from the mainboard. To power on the Pinebook Pro with the battery disconnected it is required to bridge a pair of bypass cables - please reference the picture below. 2.The bypass cables are only to be used if the battery is disconnected. With the battery connected the bypass cables will cause high current to pass through and trigger overcurrent fuse protection when power is supplied from DC barrel jack or USB-C port, which will cause damage to the mainboard.
