    Hi,

    I have built a small ITX system which I have running on DC,
    I have made my own Lithium ION Battery Pack which is configured to run at 24v,
    and sometimes I use it on a 12v battery.

    Can anyone help design a circuit which automatically detects my input voltage (12/24v)
    and the shutdown voltage can be adjusted by a variable resistor for both voltages.
    send a pulse to computer to shutdown...

    I could always reconfigure my Lithium Ion battery.. to run at 12v, but higher voltage is good for me.

    thanks

    How would you select which shutdown voltage the circuit should operate at?
