Dimension 2400 Keyboard Controller Failure and other problems

  • Dell Dimension 2400 Bios v A02

    Having problems on startup which goes as follows:

    Starting the system like so

    Attached:
    PS2 Keyboard and PS2 Mouse

    Activity:
    Lights flash on Keyboard
    D Led is Amber

    Error Message:
    Error 8602- Auxillary Device Failure
    Keyboard controller failure
    Strike the F1 key to continue, F2 to run the setup utility

    ----------------------------------------------------------
    Attached:
    PS2 Keyboard

    Activity:
    Lights flash on Keyboard
    D Led is Amber

    Error Message:
    Keyboard controller failure
    Strike the F1 key to continue, F2 to run the setup utility

    --------------------------------------------------------------
    Attached:
    USB Keyboard

    Activity:
    Lights flash on Keyboard
    All Led's are green

    Error Message:
    No error messages, just a blank screen, on start up pressing
    F2 or F12 does nothing.

    --------------------------------------------------------------
    Attached:
    USB Keyboard and Different hard drive with old win 98 install

    Activity:
    Lights flash on Keyboard
    All Led's are green

    Error Message:
    Gets into windows but says no ps2 mouse found, doesn't recognise
    any keyboard input to continue but i'm nearly sure this is because
    the usb kb would need to be installed in windows.

    ---------------------------------------------------------------

    I guess the ps2 ports are knackered, I downloaded the Bios Update v05
    and imaged it onto a few different floppies but everytime i boot from
    any of the disks it always stops at "Loading Rom Image" the green light
    on the floppy drive is lit yet theres no activity from the disk

    Have also swapped memory to see if that was causing it with no luck
    Have also reset the Bios and changed the CMOS battery, none of which have
    made any difference.


    Anyone got any Ideas

    Thanks

  • The chain of evidence suggests the chipset, permanent part of motherboard, is knackered.  USB drivers support Windows-specific keyboard features, but the system is supposed to respond to USB keypresses without any software loaded.
     
    Thorough procedure, I'd say, resetting BIOS, changing battery, swapping memory, trying different configurations.  If you could swap PS2 keyboards with one that definitely works on another machine, that leaves only chipset/motherboard.
