@realkrzysiek Dogrzebałem się w końcu do wpisów z opisem tego rozwiązania Dell-a. Rzucisz okiem?
Cytuję:
"Using this information, I was able to identify the power adapter I.D. circuit in the dead power adapter. In my case it was three components on a 3/8" x 5/8" 'perf' board. (one 330 Ohm resistor, one diode looking device across the single line memory I/O port (probably surge suppression) and the single line memory device in a plastic transistor case, with only two wires connected to anything. I removed that circuit assembly from the dead adapter, and moved it from between the third wire and the minus power supply reference in the old adapter to the place in the d.c. cable where I spliced the Sony 2 wire cable into the 3-wire plug-tail from the old Dell cable, (on the adapter side of the ferrite RFI suppressor).
As has been told by others, without this adapter I.D. circuit, the two-wire adapter would power and run the laptop fine, but the error message indicated there was trouble with the adapter. After the I.D. circuit was added to the cable, the error message concerning the power adapter cleared and the battery charges."
Niestety strony z opisem, na którą się powołuje, już nie ma, 404.

Dell laptop DC power jack pinout
Archived from groups: alt.sys.pc-clone.dell (More info?) Hi, I'm attempting to wire in a different DC power jack (the original broke and direct replacements are not available except by purchasing a new motherboard) on an Inspiron 8600 and thought that it would be a rather straight forward...
