Unfortunately, it's probably dead. The power input circuitry of laptops is what kills most of them, whether Apple or otherwise. I have an old laptop which to all appearances looks totally dead, but will on very rare occasions switch on for no apparent reason... only to not turn on again if shut down. I can't even imagine what's gone wrong electronically there.
It tends to happen when the batteries are old and failing, so it may be something to do with damage trying to charge dead batteries. I always advise removing failing batteries ASAP.
