    Hi. I have an old Dell laptop that I want to convert into a small server. Ido not't have an original dell charger but I have an aftermarket one. It won't let the CPU run at the full speed without identifying the power adapter. If emulation is possible using a PIC can this be done using an Arduino or an AVR microcontroller. I have plenty of atmgea8 and atmega88 that can use to bypass this but I do not know how the communication works. Can some one help me to make an emulation using AVR please?

    Hi. Can you please send me the source code please so that I could convert it to an AVR microcontroller please.

    Can you give me the source, I need to convert it to pic12f675 or 12f509...

    All others of you, if anyone got source code in a meantime, don't hesitate to send it to me.

    Thanks in advance.

    I've tried Dell PSU Emulator based on PIC10F220 but it is not working.
    I've found working one:

    There is attachment with source code and binary HEX file.
    I've tried with ATtiny13A and external 3.3V power supply (for testing purposes).

    Fuse bits: 9.6MHz Internal RC and turned off the DIV-8 option.

    Thank you.
    I'll check it out.

    There is a strong reason why Dell PSU Emulator based on PIC10F220 isn't working, for ANYONE!
    What I mean, you'll see in my following quote ...

    Yours claimed code for PIC10F220:
    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":
    :02 0000 04 0000 FA
    :08 0008 00 0528 1F28 A300 A400 35
    :10 0010 00 0830 A200 2508 A306 A30C 2508 A300 031C 92
    :10 0020 00 1328 1830 A306 A30C 2308 A500 2408 A300 56
    :10 0030 00 0310 A30C 2308 A400 A20B 0A28 0800 A501 A2
    :10 0040 00 F030 0620 1030 0620 0000 0030 0620 0000 AE
    :08 4000 00 0100 0200 0300 0400 AE
    :02 400E 00 F93F 78
    :00 0000 01 FF
    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 ...

    Looks like this thread is regaining some life...if there's still anyone interested in my original source for reading the chip, I'll dig through my oldfiles and see if I still have it, I pretty much had the entire command structure written up in code so it shouldn't be too hard for someone else to finish it. Maybe I'll even whip up a new version. Let me know.
