What to do if your laptop charger is buzzing

If you have been happily working away on your laptop only to notice an annoying buzzing noise, what is going on? The sound will indicate that something is amiss with the laptop power supply and that it is either on it’s way out or has already broken. The hissing or buzzing sound could be because of a couple of faults. One being, when the laptop adapter is plugged into the laptop, there is some kind of short between the tip of the adapter and the DC Socket within the laptop. The crackling sound will be caused by the electricity jumping across the circuit.

Another possible cause would be a component inside the charger failing. If the power is not flowing through the charger as it should you may hear a sound. Again, some laptop chargers will have a warning system within them to give a high pitched sound when something is wrong. If you are hearing these sounds it is in your interests to look for a new power supply. Let Laptop Power UK help you out n your search for a replacement, visit us at
