The buzzing is probably the capacitors and other components transforming the electric current coming from the wall to a volt, watt, amp, ect...that your laptop can use best. If it weren't for the transformer box on the cable, we'd only need a long piece of wire to run our laptops. But computer companies have designed their laptops to use different ampherage voltage, and wattage as compared to your standard electrical current for battery and charging efficiency, as well as a small way to add more money onto the price tag. It's not a big problem, its just your cable doing its job

The power lines are buzzing because of the electromagnetic fields created by the electricity flowing through them.

Every laptop has a different power rating.
Power lines can buzz due to electrical current flowing through them, which can indicate potential issues such as overloading, loose connections, or equipment malfunctions. This buzzing can pose risks of electrical fires, power outages, and even electric shocks if not addressed promptly.
To ensure the safety of power lines when they are buzzing in the rain, it is important to stay away from them and avoid contact. It is recommended to report any buzzing power lines to the local utility company immediately so they can address the issue promptly. Additionally, it is important to avoid touching any objects or surfaces that may be in contact with the power lines to prevent electric shock.
Trees do not normally 'buzz'. Buzzing can be a sign that there is a fire on some part of the tree, and that is the tree's way of reacting to the fire. Buzzing trees can easily be mistaken for buzzing power lines that run around or through a tree.
The HP Pavilion comes built on the Centrino plaform and so will have a good battery life of three to four hours.
no,on Portable laptop power supplies typically have larger battery capacity than laptop battery , so the battery more durable
heat sink fine+laptop won't power on
Dell laptop power cords are generally only compatible with Dell laptops, as each brand of laptop has its own specifications for batteries and power cords.
