Finding the Right Model of Adapter :

· Get the laptop's model number. This is usually printed on a small sticker affixed to the underside of the laptop.

· Get the power requirements for the laptop. This is also printed on a small sticker affixed to the underside of the laptop. It may also be printed near the laptop power port. Look for the amperage and the voltage required.

· Look up the model number online to find if there are compatible adapters available. The voltage and amperage of the adapter need to match the requirements of the laptop.

· Compare the connector type of the laptop adapter to any available adapters found online. They need to match to ensure that the adapter can plug into the laptop.
