Lenovo ThinkPad T480s Wi-Fi Card Replacement

crwdns2915892:0crwdne2915892:0

This guide will show you how to replace the Wi-Fi card in a Lenovo ThinkPad T480s laptop.

A Wi-Fi card, also known as a WLAN card, enables the laptop to connect to a wireless network. If you cannot connect your laptop to Wi-Fi, or if you are experiencing intermittent connectivity, you may have a faulty Wi-Fi card. Be sure to rule out other connectivity issues listed here before replacing your Wi-Fi card.

Make sure to disable the internal battery, power down your device, and disconnect from any external power sources before you begin.

    Somehow I find the screws for the T480s bottom cover to be slightly more prone to stripping, compared to the ThinkPad T480 and X1 Carbon Gen 6. However, the #1 Phillips screws on the T480s have drives that are cut in a way that also let you use a #3 flathead.

Hi, thanks a lot the helpful guide. I have just replaced the WiFi card in my Lenovo T480s with a Intel AX210NGW. My laptop won't boot up. Even when I plug the power adapter into the laptop, the status indicator does not light up. I have removed the WiFi card and tried to power it on without it but no luck. I put back the one that was in before still no luck. I'm stuck, what can I do? Did some power component get disturbed or something? I'd appreciate any help. Thank you.
