Laptop AC adapters are designed to be used with alternating current
, the normal way of delivering electricity in this country. The part of the power supply cable that looks like a small box is the transformer, which converts the voltage from the mains supply to a lower power suitable for the components of laptops. AC adapters will become warm or even hot while in use so it is important that the adaptor is not put underneath other things that could trap the heat and potentially cause a hazard. Making sure that there is adequate ventilation helps to maintain the efficiency of the AC adaptor as well as protecting it from accidental overheating.
When the adaptor is plugged in to the laptop it is important to check that the light has come on as this will show that the connection has been properly made. If the light is not on, then the battery will not be charging, which could be inconvenient if you do not notice until you want to use the laptop.
