Laptop vibrates when charging

  1. Hi all!
    I just came to China yesterday, and I noticed that when I charge my laptop, the part of the case above the battery will vibrate very slightly. When I remove the charger, it stops vibrating. I know for sure that this doesn't happen back in Canada, and I wonder if its because of the voltage differences. (canada= 120V China= 220V) However, There is a transformer on the charger, that says it can handle up to 240 V. This also happened on my trip to europe too, and I wonder if continued charging could damage the battery or laptop.

    It's a HP Laptop.Pavilion dv6

    It should be okay but watch for excessive heat either from the charger or the battery compartment
