Compatibility

Each adapter has values for its input and output in terms of voltage and polarity. For the Lenovo laptop adapter to be compatible with another system, these values must match the power needs of that computer. Reference the system’s documentation or its original adapter for specific information on power requirements.

Components

Most Asus laptop adapters come in two parts: a cord that connects to a wall socket and the adapter that connects to the computer. These two components also must be electrically compatible with each other to supply the correct amount of power.

Ports

Different manufacturers use different ports and hardware configurations with their adapters. Even if an adapter is electrically compatible with another system, it may not physically connect due to incompatible port configuration
