question:
Review: I plugged this item into my laptop and nothing happened. No power- nothing.When I unplugged this adapter the negative metal ring from the plug stayed lodged inside of my computer, I had to remove it with needle nose pliers.I had to call the company 5 times before getting a rep on the phone as I was continually placed in automated limbo for about 15 per call. The rep actually admitted to me that this happens alot because the rings are too small and fit to tight in the computers.I was really looking forward to saving some dough. But this adapter was surprisingly worse the the original that came with the computer.They are sending me return authorization. 
 Polarity: Positive
answer:

False
