A:AnswerIf nothing is plugged into the hub and the blue light is on it either means that power is left in it after the laptop is shut off or it means that it is drawing a small amount of power.
A:AnswerThis is simply for Type A ports, it does not have a HDMI plug in, you should find another hub such as the "Hyper - 7-Port Universal USB-C Hub - USB-C Docking Station for Laptops - Space Gray" as long as you have a USB-c port that can transfer data and power.
