Problems solved by technology

The power cords of the existing power adapters are all connected outside the main part of the adapter. Because the power cords are long, they tend to become disorganized and inconvenient to use when retracting and carrying. The main part of the adapter takes up a lot of space, although now The size of the notebook computer is getting smaller and smaller, and it is very convenient to carry, but its corresponding power adapter has not change

Description

technical field [0001] The invention relates to a power supply module and a notebook computer using the power supply module. Background technique [0002] At present, rechargeable batteries are widely used as a fixed power source on notebook computer products, but the capacity of rechargeable batteries is limited, so that the working hours of notebook computers are relatively short, and the power of the rechargeable batteries will be exhausted after a few hours of general work. In addition, general notebook computers are also equipped with an external power adapter to obtain the rated voltage and current required for normal work. The power cords of the existing power adapters are all connected outside the main part of the adapter. Because the power cords are long, they tend to become disorganized and inconvenient to use when retracting and carrying. The main part of the adapter takes up a lot of space, although now The size of the notebook computer is getting smaller and sm...
