Hmmmm.....if the battery is just about a dead short....stick it in, it pulls
power down to the point where it forces a CPU reset. Mac resets....power
supply goes <<grunt>> and tries to dump enough current to charge batt and run
system. IF the battery has a bit of life left, the internal resistance may
rise enough to allow the system to then boot.
Not good for the unit, BTW. A dead/shorted batt forces a lot of current thru
the charging circuit. You <<could>> actually damage the charging components
on the logic (tho I'd have to look at a schematic to tell for sure....anyone
have a 2300 schematic?? <<BIG grin!!>>). Also, if you are using an older
adapter, possibly the amperage is just low enough to have a sufficient
voltage drop when a good but discharged batt is inserted.
Best to charge ""unknown"" batts with the unit off, THEN try an operational
start & insert.
