Battery not charging, not detected in OS.

Hi!

I recently took out my sshd to test another hard drive / cable. Before I unplugged the harddrive, I unplugged my battery from the main board.

Upon reinstall of my harddrive and reconnected the battery, the battery no longer is detected.

I recently noticed that my battery indicator on the left side of my MacBook Pro Mid 2011 13 Inch Unibody is no longer working either. The laptop will only work when plugged in.

The battery is not detected when I go to system / power.

I have ordered a new battery from IFixit and no success. I have tried the SMC reset and all the other reset procedures but nothing. I’m out of ideas.

There was no water damage or other issues before.

Disconnect the battery tester ribbon cable and see if the system works that way.

Yes the computer works when the battery ribbon is disconnected and computer is connected with the MagSafe charger.

So I disconnected the ribbon cable that is next to the battery plug. The laptop works still. So what does that mean?
