There is a good possibility that it is the battery.  Usually, if you wait for
a day or two and try it again...it may come on.  You can also get 6 volts of
regular batteries and attach them to the old betteries to see.  I dont remember
*exactly* which of the four leads to use so unless you know what you are doing,
dont do it.  Those batteries have been known to burst if they are messed with
in the wrong way.  As memeory serves me.. this is how things are done.

PLEASE double check this before you do anything.  You need to hook up the
batteries to the two leads marked "here".  I know a guy that has a small
batery holder he got from radio shack just sitting in his Mac.  You can buy
an aligator clip and use it to attach to the batteries for easy de-installation.
