MacBook Pro runs on battery, but shows 'X' signal


i received late '06 2.16gb core 2 duo 1tb hdd (upgraded) 4gb ram macbook pro.

now, not boot off battery. once connected power cord, boot. can remove cable , continue boot battery.

so, run battery.

software however, shows x symbol along 'no batteries installed'. system profiler gives same info , coconut battery says nothing in there well.

macbook pro not charge battery, run out , magsafe connector keeps it's green light @ times.

tried resetting pram , smc , pmu well.. no avail.

knows can problem? runs when booted on battery when disconnected ac..

also, tried brand new battery well. tried 2.
 

pram/nvram has nothing battery/power/charging issues. resetting not help. resetting smc addresses such issues. try resetting smc again.

if smc reset doesn't help, check out link troubleshooting magsafe adapters @ bottom of charging section of following link.

if doesn't help, , problem exists new battery, may have problem logic board. these apple batteries, or knockoff batteries?

should answer most, if not all, of battery questions:
