why not just buy a used power supply for cheap on ebay??

First of all, you sure you have one of those supplies? I think you do, but not 100%.
I was reading this post by bugbyte:
P1900 + Dell Laptop and docking station
and it describes my charger exactly. So i also believe that i do have one of those connectors.
My originial question has never been answered though, if i cut off the end of my OEM dell charger would that work without a doubt with my p1900 since it will have the chip in it?
Thanks for all the help guys, i'm sure theres a bunch of other people with teh same problem
Maybe if you could extract the chip out somehow and get it to work being powered by the p1900, maybe something could happen, maybe not. I don't know if the chip just reports info or something or it may actually be part of the charging circuit, no idea as it's all proprietary so no datasheets, etc.
Probably the most likely solution would be for someone with an oscilloscope try and figure out what's being communicated, and then making a dummy out of a PIC that says what it wants to hear.
first of all, the Lind is the only adapter that WILL let the battery charge.... I had a dell 700m with the large barrel connector... the Lind works 100%...
since I swapped out the dell for a gateway that also needed 19v, but had a different plug, I cut the plug off of the lind.... it uses 3 wires of course, but it's weird.. it has like 2 different voltage feeds, & I think one has a ground level that is 5v above the other... I didn't spend a lot of time analyzing it, cause when the 2 outputs are summed, the end result is 19v, which suited my purpouse....
I don't think there is any communication, just a weird voltage configuration.... either way, if charging the battery isn't important, then the p1900 will definitely do the job... otherwise get a lind adapter for your model & it'll charge 100%....
Anyway, any reason to get a Lind instead of just use the PSU and a regular inverter? Certainly seems cheaper to get a regular inverter.
Anyway, if you go the Lind route, make sure it's big enough (watts) for whatever you are going to do. A dock requires a bigger one (at least the Inspirion) and it dies at the BIOS with a power message. Funny, it won't boot with a dock if you are on battery, though if you remove the power after the BIOS post, it all runs fine on the battery.
God I hate Dell.
