How come when I unplug my new HP laptop from the power, it makes a slight screeching noise?

It's really annoying. I'd like to make it go away. Lol. It doesn't always do it either, but most of the time. And sometimes it stops if i close the computer, then open it back up.

1. sounds scary....I think you should give it an exorcism....just a thought...
2. i get the same noise.....I found out that it is the wireless card inside your laptop....The only way to get rid of it is to turn off the internal wireless internet card.
3. Sometimes when you plug or unplug the power adapter into the wall, you may see a spark. This is usually normal and can occur when you plug any electrical appliance into a live outlet. I used to get same noise. Try pulling out the electric plug from your computer first, then pull out the plug from the wall. Good luck!
