Battery Is Not Charging

I just bought faulty mac from ebay, and trying to restore it.

I just tried to launch it without battery, and it was ok. after I bought new battery, and installed it, Its working fine, but have problem with charging.

Actually problem is: no any lighting(orange or green) on Magsafe connector and OS indicating "Battery Is Not Charging" but charger charging battery very slowly.

I already tried to reset SMC and PRAM with no success.

May be there is some solutions at this case?

Probably I bought faulty charger or MagSafe logic circuit?

There is some info about Power in my system:

Have you tried a second charger yet?


yes, today I been in Apple Store and tried to connect L-shape charger, and it had green light on connector, but had same problem "Battery Is Not Charging


system power information was shown same description. in my opinion its looks like system dont recognising charger.. Which component or circuit is responsible for it? it can be Magsafe DC-IN BOARD Power?

At this point you'll need to open the system up to see whats up.

The DC-in board is mostly passive in this model (very little circuitry). The underside of main logic board near it has most of the battery control logic.

Look for liquid damage or a burn't component on both boards.

Make sure you follow proper ESD practices. Good Luck!
