Robert Kahle's 2007 post was all I needed to hack the adapter. Using an

8 pin microchip 10f220, I wrote the following code. It's the .HEX If

you want the source PM me.

The code aint pretty, but it works.



This sends a fake 90W signal to the mobo to make it think a dell adapter

is connected. I needed it because I'm off grid and I only have 24VDC.

I step this down t 18V and use the PIC to fool the mobo. Been good for

9 months now.



You'll need an old plug to connect to the laptop and you'll need to

identify +, - and signal (centre) pin.

Connect 18V into the laptop. The centre pin of the goes to pin 3 of the

PIC.

Put a ge diode anode on pin 3, cathode k on pin 2.

Put 0v on pin 7. 330n cap pin 2 to pin 7. You get about 2.5V on pin 2,

which is just enough to power the PIC. The PIC waits about 200ms and

then sends the message when requested by the mobo. There is so little

current sent by the mobo that you can barely light a LED, so only use a

DVM and dont connect anything else!



I've tested it on 2 d610 and 1 d600. Flawless!



You'll need a good grasp of electronics to make sense of this, not to

mention programming PICs. I'm not selling these and dont intend to.

WON'T work for PIC10F220, because that microchip has a 12-Bit Opcode and yours "claimed code" is for microchips with support for 14-Bit Opcode! (i.e; PIC16F688)

Firstly I'll format yours "claimed code":

Ignore first 3 columns and last 2 digit column.
Now, all 4 digit pairs, in between, are words!
And here comes an ultimate proof, that this code is for microchips with 14-Bit Opcode, meaning NOT for PIC10F220!
Code for PIC10F220, would have ZERO as third digit in EACH word, which isn't case here!

Additionally ...
It doesn't even have ANY OF LISTED IDENTIFICATION CODES of AC power supplies!
So, how can it send it, in order to emulate Dell's AC power supply?!?!

Lastly ...
Reverse engenired it and it practically does "some" nonsense!

And what you said? Oh yes ...

The code aint pretty, but it works.

You are liar and time waster!!!

GO **** YOURSELF, YOU TIME WASTING PIECE OF **** !!!

Corporation like to hire "smart ones" in order to bring confusion into community, so that case is also an option.
Especially because this is an INTENTIONALY DESIGNED PARASITISM FROM DELL. Well **** them!

What really frustrates me, is that NOBODY, hasn't detected at least ONE of my 3 detection steps !!!
THINK! Or OTHER will FOR YOU, straightly into THEIRS interest! Yea, be theirs bitch!
