With our vacation starting tomorrow, I'm hoping someone can help us with our dead GoPro hero 4 Silver. It was working fine last weekend and we attached a Digipower Refuel battery bacpac for the first time. We used it for a few hours and left it attached overnight. The GoPro wouldn't power on the following morning however. It doesn't seem like our powering-on issue and the first time use of the battery bacpac are a coincidence. We have tried all of the common suggestions (removing battery, changing charging cords, new battery, etc). It also does not power on when plugged directly into the wall (with no battery or SD). Would greatly appreciate any recommendations?

Thank You!!!

I didn't find the right solution from the Internet.
