My MBP A 1286 vintage 2011 suffered a lightning strike. It was in sleep mode when it was hit and when I later went to use it, the battery was down to less than 10% but the computer was still operating! Yippee!

But wait, there's more... I found that the AC power supply and magsafe receptacle were burned up. So I ordered a new, non-apple AC power supply and a new receptacle and replaced the burned out parts. I also removed the battery to check it, but it seemed OK and I put it back in place. Now the MBP will not turn on at all and no green LED. Not so Yippee :-(

So some questions:
1. Did moving the battery cause the problem? I did not move any battery cables.
2. There appears to be several interlock switches that detect if the bottom is removed. Could this be a problem?
3. Assuming the battery is now "dead", is there some procedure for booting.
4. Anything else I should check?

I am handy with electronics, soldering, Arduino, etc. I do not need to operate on a battery. Is it possible to disconnect the battery and supply the the proper voltages directly to the MBP thus by passing the battery?

Thanks. Any and all help is appreciated.

I would try taking it all apart again and making sure all the connections are inserted correctly. Hope you get it going again!
 
If the OS does not detect a battery, it will throttle the CPU down to its lowest speed.

When you say "MagSafe receptacle", are you referring to the a board inside the MacBook?
