Would it not be feasable that you purchase the wire that comes of the connector on the motherboard and has the proper end for the charger? This way you could get the adapter that is appropriate for the G50 and plug it in and check the wiring. lots of them [http://cgi.ebay.com/DC-POWER-JACK-w-WIRE-HP-PAVILION-G50-119OM-G50-120CA-/280628499412|on eBay] You could of course continue with a custom enclosure since the wire will give you the option to place the power connector wherever you need to. Just my thoughts on this....:-) good luck
