How to power Mini-PC on robot?

[team-4480]

Hi,

We have a mini-pc that we would like to use for some advanced image processing that can only be done on a full-fledged mini-pc. We wrote the code and tested it and it works great. Now the problem is powering it on the robot. On the AC-DC converter, it states that it outputs 19.5V @4.62 Amps. We found a 19V 5A adapter, but unfortunately, when we plug it in, the mini-pc beeps and gives a red light indicating that the power supply isn't good enough, likely due to the lower voltage.

Has anyone ever done anything like this, or does anyone have an idea on how to properly feed 19.5V to the mini-PC? Also, what are the rules regarding use a DC-DC converter?

Thanks a bunch in advance!
