The whole process was super troublesome..... i think total of more than 48 hrs..... 2 visits to Genius = 3hr + 5 hrs (not including 5hr drive both way per trip).
Calling apple care, going to the troubleshooting process,... more than 40 hrs in the 7 weeks period.
Finally, they agreed to send a replacement,... but i procrastinate (partly waiting for the new smaller power adapter, partly waiting for QA to be stabilized, less yellow tint issue and hopefully heat issue) sending the faulty MBP in.
