Find right adapter for your laptop
You need to know the exact type of adapter that your laptop notebook require before you buy. There are many different types of adapters available. They may have same power voltage and amperage but different connector tip or same connector tip but different power. Thus, they are incompatible with each other. Most of the laptop adapters are only compatible with specific laptop brand and model. The laptop model number, power requirements of the adapter and connector type of adapter are required in order to find compatible replacement adapter.
● Look for laptop model number, which is often on a sticker on the bottom of the laptop or back side of the laptop.
● Find the laptop's power requirements, which are also usually printed on a sticker at the back side of the laptop. Sometimes it might be printed on the power port of the laptop. Take note of the voltage and amperage required.
● See which charger is compatible by checking out the Laptop model number from website by searching with laptop model. It is important that the voltage and amperage of the replacement charger must match written on the the laptop or match with faulty (original) adapter.
● Also, make sure that the charger connector tip matches the connection port on the laptop; otherwise, the adapter won't work if it cannot connect to the laptop even if specification else is ok.
Although laptops are meant to be mobile, their batteries do have to be charged using adapters ever so often. The 2 main kinds of adapters for laptops are AC & DC power adapters. They both convert power from an electrical source into a form that can be used to power the laptop. For the adapters to work properly, the amperage, voltage and connector type all have to match the requirements on the laptop. Otherwise, the laptop will not charge properly. Only one kind of connector will work on any given laptop, so it is important to get the right connector.
