Yes im also a victim of this “phenomena”. I researched the net and luckily found out that its covered by applecare, what a relief! The problem now is that I lost my MBP’s receipt. For the meantime while digging my storage… I bought new one. I hope it doesn’t not come with the same “phenomena”.
So if you have the same fate with your power brick i suggest that you replace it right away You’ll never know if you will get electrocuted and fire blast.
my new one, white & clean
