PC Auto-power-on

  1. I have a notebook (Dell) with an application that I want to auto-start upon
    boot. That part is easy. How do I get the PC to auto-power-on when power
    is applied (A/C)? BIOS has settings like what do do when you close the lid
    or "Wake on LAN", but nothing about when power is reapplied.

    Any thoughts? Don't want to modify the power switch, doubt that would work.

  2. For starters you will have to remove the battery pack.

    If it was an old PC then you could leave the power switch
    set to on.

    The new-fangled computers have a 'soft' power switch(es).
    The question then would be what happens when the PC powers
    up (or the start circuit powers up) and sees the on-off
    switch closed.

    Try putting a weight (or whatever is needed) on the on-off
    button and plug the PC in.

    Yep, problem is most PC's with a softbutton will turn off that way as well.
    But I think most require you to open then close the button contacts once
    before that will happen.

    If you have wake on modem, you can simulate a signal on the ring indicator?
