I'm gathering from all the work that uniserver has done nothing but the original adapter should be used with the portable as the power management IC's were not made to power on from the power port. I did it until I called my battery in my portable non backlit but I won't chance it as he has a stack of bad boards with power management issues.

Weird that the 7.5 x 3.0A is for the 180. I have the 180 but not that cord, I use th low power ones I have. So am I hurting the power supply using it?
