The DC end that goes into the laptop was unplugged and the AC end was plugged into the mains (actually the plug sucks, so it could have been that it was...you know...just on the border. Getting and losing contact many times in a short amount of time if I moved the cable a bit) ...So one of these times that I just touched the cable, it did this chirping cricket sound and I unplugged it immediately. It did smell a bit weird, but I'm not sure if that's normal (due to heat or whatever)..

So, should I be afraid of if? Can it kill my laptop if I try charging it? I only have around half an hour of battery left. Please help.

Hope this is the right StackExchange site to ask.

Thank you in advance
