b) if i disconnect the power supply, it power off

c) with only the battery, it doesn't power on

d) when i connect the power supply (with or without the battery), it power on itself

e) the led of the power supply is always green

f) i have 5/8 led on the battery only if i connect the power supply

g) i've try to reset smc. but it doesn't work (led always green)

h) if i hold for then second power button, then i connect the power supply then i release the power button, it power on with fan at max speed, but the battery is not seen anymore

i) i've try to do all those thing with the motherboard outside the case and with anythign connected, it doesn't change, i've always the same problem

Is it a genuine Apply battery and Apple power supply? or are any aftermarket?

Can you swap in a similar battery from someone's else's Mac?
That will allow you to isolate the battery and its internals as the problem.
The symptoms sound like the charger circuit is working, and the computer will run from that, but as soon as you remove the external AC /charger source - the battery is 'not there' !!

yes you are right! in another forum some says me

"i5-i7 model power on themself if battery not connected."

so the best should be to find another battery and try!
