It is funny you're asking this question and I just figured it out two weeks ago. I tried as all of us have to run the laptop on 12V DC cigarette lighter. No joy, no results and finally no nada. All laptops including my dell have a voltage low limit. I.E. my input is 19V DC and the laptop battery is 11.1 VDC. if it is less than about 16 V it will not function n at all. Now here is the trick. I have a Ryobi cordless tool kit from Home Depot that runs on 18V DC. I have an on vehicle charger charging the 18VDC batteries from my cigarette lighter so the batteries are charged from my bank batteries. what I did when my mind started looking for reasons to beat the system. I bought a ryobi flashlight for $12.95 and driled a hole on the side. I soldered two wires positive and negative to the flashlight socket from inside. I used my solar panels harness that has the same plug as my laptop to connect the wiring from the flashlight to the laptop and BBBBBIIINGO. IT WORKS!!! and I don't have to buy a dell battery for $130. Two Ryobi batteries $46. About the scanner I have an Acer scanner that runs on 12 VDC and a Canon Pixma 1600 the same. As for the printing cartridges they cost almost $50. The printer is $60. When the colour is empty printer goes to value village and buy a new one. I hope hat helps.

The output from my power brick says 17 volts, but the internal battery supplies 14.4 which most likely drops to less than 13.8 when under load - so nominal ~13v dc aught to run it. Question is where to make the connection. Just plug into the power inlet in the back like the brick does? Any problems with this hook--up?
