[Duo2400] Re: 2400c battery not recognized

[Art Rice]

Hi,
I hope I am not telling you something obvious to you.
My apologies if so. It sounds like it could be a
battery that won't supply enough current to power the
Powerbook circuitry more than a second. The following
assumes that a 2400 battery is supposed to be 12
Volts(I'm guessing because I own a 2300c). First, if
you have a voltmeter, check the battery voltage. If it
is 12 volts or so, connect the battery to a small 12
volt lightbulb, like a 12V tail-light for an auto. If
it lights the bulb and it stays lit for a minute, then
the battery is probably  good enough to power up the
Powerbook for a short time. I don't have time right
now to look up how much current the Powerbook draws,
but it can't be much if it is powered off the AC
adapter.
