Thread: Zenith Data System ZDS 625 NL

  1. #1

    Default Zenith Data System ZDS 625 NL

    Dear All,
    I have the possibility to buy a Zenith ZDS 625 NL... but the PSU is missing!
    And the power plug is... quite strange.
    Have somebody some info on how to build the connector to be used with a "standard" PSU... or better the possibility to sell a suitable working PSU?
    B/R

    I made a small step... I have found an old ebay auction with a BIG photo of the AC adaptor...

    If I understand well:
    21V charge is only needed to recharge the battery... so if this is not needed...
    21V output is to turn on the laptop
    GND is... GND
    CTR?
    Does anybody have idea about the connector type?
    It seems a connector similar to PS2 ones...

    Probably... but which type of control? I suppose the computer decides what to do with the AC adapter, it can probably tell the PSU to recharge the batteries OR power the computer... so that electricity only arrives through a single pin and through both... if it's so, can I simply use a standard AC adapter deciding for example to power the computer without the "permission" of the computer itself? A possibility would be to simply remove the batteries...

    Assuming:
    * 'CTL' is a control signal to the power supply
    * '21V CHARGE' is only used to charge the laptop's battery
    * '21V OUTPUT' powers laptop circuitry other than the battery

    Yes, one possibility is that the 'control' line tells the power supply to disable the 21V CHARGE output, because the battery has reached full charge.
    It does not make sense to me that the 'control' would enable/disable both the 21V CHARGE and 21V OUTPUT.

    Educated guessing.

    The web page is from a former seller of Zenith parts. I captured the web page before it was taken off line. The links aren't corrupt. The links are dead now.
    I doubt you will find one place where most of the Zenith laptop adapters are listed.
