MacBook Pro won't feed - need to disconnect/reconnect the battery.

I have a 'early 2011' MacBook Pro 17 "which does not illuminate when the power switch is pressed.    He worked normally in the last time it was used.

I'm a PC I / specialist t so I did some fault finding.  Here are the results and measures, I tried:

  1. Power button and no indication button has been pressed.
  2. Button on the side and he said fully charged battery.
  3. Adapter a/c and LED power connector attached LED lights up in green as it is supported.
  4. You press the power button - still no indication of any attempt to power on.
  5. Let Reset SMC pressing SHIFT, control, Option, and power switch.  All released.   You press the power button - still no indication of any attempt to power on.
  6. Power button which is held down for 15 seconds, released, then no hurry once - no change.
  7. Disconnected a/c power.
  8. Removed the back cover.
  9. Battery disconnected from the system board connector.
  10. Connected a/c adapter and power button pressed - no change.
  11. Disconnected the a/c adapter.
  12. Back in the connected battery system board connector.
  13. Joint a/c adapter and the system performed a reset, then IPL upward and ran normally.
  14. System "Shut down" and then press the power button - would not be back.
  15. Removed the a/c adapter and pressed the power button - still wouldn't back off.
  16. Disconnected a/c adapter, disconnected the battery, battery reconnected to the system board.  Power button - will not turn on.
  17. Repeat the procedure which worked previously - a/c offline, disconnected battery system board, connected a/c, press button power (no signs of activity), disconnected a/c, battery reconnected to the governing body of the system, reconnected a/c and it reset and power!
  18. Let system and then "reset" (instead of closing) - it restarts correctly.
  19. Shut down the system and then I tried to power - will not turn on.
  20. Bottom line: it seems that the procedure which will get the system starts, after it is closed: disconnected a/c, disconnecting the battery system board, connected a/c, press power button (no signs of activity), disconnected a/c, reconnected battery to the system board, reconnected a/c and it resets and starts.

OK, so you MacBook Pro experts out there... what seems to be the problem and what measures would you recommend I take?

THX,

Jeff
