Back At The Apple Store Again-5th Time in 2 Weeks! Hissing Charger

Back At The Apple Store Again-5th Time in 2 Weeks! Hissing Charger, originally uploaded by triciawang 王 圣 㨗.

Apple Store, Midtown NYC
so last night when I realized my macbook has burnt me, I heard a hissing sound that wouldn't stop. I then realized it was the Macbook CHARGER that was hissing!!!
I am not sure if it damaged my Macbook, so I am just taking my charger in today to swap it out for a new one, and then make sure they make note of the problem so that just in case if I have any crazy Macbook problems they will see that the hissing charger may have affected it.
I have to wait 15min for my appt, so I am at the Apple Store's powerbook display blogging about my Apple problems. Meta Meta Meta
