Lenovo Yoga 900-13ISK Wi-Fi Card Replacement

はじめに

This repair guide will demonstrate the process of replacing the Wi-Fi card in the Lenovo Yoga 900-13ISK 2-in-1 computer. The Wi-Fi card is responsible for facilitating wireless connections between your laptop and other devices or networks. It is connected to an antenna, usually located in the top case behind the screen, by two coaxial cables.

If you are experiencing connectivity issues, such as having trouble connecting to a Wi-Fi network or bluetooth device, replacing the Wi-Fi card may alleviate these issues. The Wi-Fi card is also known as the wireless card and WLAN card, so these terms may be useful to include in searches while looking for a replacement part. Be sure while you are working that both coaxial cables are firmly seated on the Wi-Fi card, as the card will not function without both connections.

Be sure to unplug and completely turn off your device before you start working.
