Battery did not charge, battery ondicator off, but it power up!

I have problem with my mbp 2011

Simptoms:

battery don`t charge

battery indicators off

magsafe only green

in osx it says: no battery available

if i unpluged the magsafe it goes to sleep mode.

Any ideas ?

By the way, i used apple test hardware and the result are OK! I don`t find any issues. :(

I have tried with a new battery but is the same issue, i have this problem after i change the thermal pasta of cpu. My question is: Mbp can run normal without battery indicator ? Or it won`t charge without this indicator cable connected ?

Thanks for answares guys !
