The power cable to my mom's laptop keeps making a buzzing sound that I've never heard it make. I've asked my dad, but he said it was normal. I was relieved until the cable made that noise after I unplugged it. What can it be? It is the power cable itself not the laptop.
The buzzing noise is not that of a Laptop its rather that of the Power adapter of the Laptop so there is nothing to worry about it you laptop is as good as it can be. But i would suggest not to use that adapter for a longer time because it may cause trouble in voltage fluctuations .
