May 15, 2014 7:57 AM in response to deneye2112by sheila_m.,Hello deneye2112,
Thank you for providing the details of the burning issue you are experiencing. I found some resources that I think might help:
First, I recommend resetting the System Management Controller (SMC) on your Mac (I wasn't sure if you had a removable battery or a built in battery, so I listed the steps for both):
Resetting the SMC on Mac portables with a battery you can remove
Note: Learn about removing the battery on MacBook and MacBook Pro.
- Shut down the computer.
- Disconnect the MagSafe power adapter from the computer, if it's connected.
- Remove the battery.
- Press and hold the power button for 5 seconds.
- Release the power button.
- Reconnect the battery and MagSafe power adapter.
- Press the power button to turn on the computer.
Resetting the SMC on portables with a battery you should not remove on your ownNote: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).- Shut down the computer.
- Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
- On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
- Release all the keys and the power button at the same time.
- Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

If you are still having trouble with burning after that step, I recommend reviewing the section titled "Top troubleshooting tips" in the following article:

Thank you for posting in the Apple Support Communities.
Best,

May 15, 2014 8:09 AM in response to deneye2112by babowa,If none of the steps outlined above help, take it back to Apple - they might have inadvertently caused a problem while taking it apart or putting it back together. What was the part that was replaced?
