Hello @console-cowboy ,

As you found in open issues, to include this computer I have to code the improvements of this topic. I ignore if I'll have the time to do it, but thank you for all the data that you submitted, maybe one day Dell GXXXXX computers will be supported by AKBL.

Best Regards, rsm
