I am trying to connect a solar panel to charge the battery of my Compaq nx5000. (The solar panel is a Brunton SolarRoll 14, designed to recharge notebook computers in the field).
The problem — the connection cord from the solar panel to the computer’s power-input jack has 4 possible connectors, none of which fit the input jack on the Compaq nx5000. The power cord supplied with the Compaq nx5000 has an input connector with a yellow plastic end and a circular hole with little square cutouts on two sides of the hole. So I presume that what I need is some sort of adapter with a similar-shaped connection on one end, that will fit into one of the 4 possible connectors from my solar panel.
Does anyone have any experience with such an issue? Has anyone successfully used adapters to connect differently-designed equipment? Any ideas of where to look for such adapters or what they are specifically called?
