    M2ATX not monitoring battery voltage

    Any clues?
    Car battery used to last 2-3 hours before I get the onboard computer low battery warning. Now it takes 30 minutes of use to get the warning. The M2-ATX does not seem to detect the voltage level and the carpc continues running... I never noticed this voltage level monitoring and shutdown when I the ODBII warning happened.

    I think I'll answer my own question after re-reading the M2-ATX manual :-)
    For battery voltage monitoring the M2-ATX power output mode should be set to Hardoff = never, which is not recommended. I think my battery is simply dying after 3 years and a half of carpc use.
