MacBook won't start up. Tried all recommended methods.
I recently moved from Norway to Thailand. I've charged my MacBook Air one time in Thailand, and after a couple of hours use of battery it suddenly wouldn't start up. One of the four pins on the MagSafe has turned black, maybe a sign of uneven voltage and bad grounding here in Thailand?
I've searched the internet for tips and solutions, but nothing has yet worked. I've also opened the back panel and reconnected the battery, but still no sign of life.
What should be my next step on fixing my MacBook? Change the battery maybe?
Thank you for your time!

Now I've tried replacing the I/O board, but it doesn't seem to have fixed the problem.
What should be the next step? Changing the battery or I/O cable? Or simply buying a new laptop?
