C615F with solar panel not charging with solar
Bought a C615F that includes a solar panel. It charges when plugged to a wall. However when running on battery and plugged into the solar panel, it doesn't charge. The battery will die.
I have checked the USB power cords and from what I can tell they are connected snug together.
The solar panel is indeed outdoors and gets direct sun and indirect sun 50/50 of the time respectively.
Is there something I can do to fix this, or is this a hardware issue?
Thank you
