One caveat about HP & Dell LTs is there 3 wire power supply. You can NOT use an aftermarket power supply with them. I like running a after market DC-DC power supply in the MH. With a HP or Dell, you'll need to fire up an inverter when off grid.

My DC requirement for my DELL INSPIRON 17R5737 is 19.5VDC @ 3.3A and uses a standard round DC connector with center pin on the DC output cable that plugs into the laptop.
The DELL 6TM1C external Transformer does have a three wire connection to 120VAC which I assume is two 120VAC wires and a ground connection... The DC output from this transformer uses a long cable with a standard size round DC connector that plugs into the laptop.
To run from an external DC Power Supply would only require the round standard DC connector plug and a +19.5VDC @ 3.34DC Amps capacity????
I don't see any problem running this laptop using an external DC power supply that would have 19.5VDC @ 3.34A capacity available.
I don't think I understand your comment about the three wire connection...

Look closely, at the DC connector, there is a outer shell and inner shell that carries the power to the LT. HP/Dell LTs look for a coded signal on the small pin in the center. When the coded signal is not present, the LT will function but the battery will not charge. Now you know.
