Looking at the power brick that shipped with the unit, the pins inside the power brick are really small compared to the standard power cord that shipped with the unit. The power cord is very loose and will easily wiggle and fall out of the power brick if you just look at it wrong. Even trying to tighten it up with some tape around the outside of the power cord doesn't achieve anything
