Tips: This is the adapter plug converter Cable via USB Type C Female to laptops. You need one USB-C Adapter to support it,and the USB C adapter should has enough power (wattage) to charge the laptop.

Please make sure Your USB Type C Adapter's wattage (volts and Ampere) is not lower than your laptop input (you can check it on the bottom of your Laptop). For example, your laptop input is 19V 3.42A 65w,then your USB C adapter is not lower than 65w. Some customers often use their usb c phone adapter to charge the laptop,very small wattage,of course it does not work. Please kindly note that not all of the USB Type C Adapter can fits for your laptop.
