How to install
Before you start: create a restore point (Start → type "Create a restore point" → Create). It takes a minute and lets you undo everything if the new driver turns out worse than the old one. This driver is made for Windows 11, Windows 10 (64-bit) - if your Windows is different, look for another version further down the page.
- Download the file with the button above - it comes directly from Lenovo official catalog.
- Double-click the downloaded file and follow the prompts - the installer does the rest.
- If it asks to restart the computer, let it.
Check it worked: open Device Manager again. The device should no longer show a warning icon, and its driver version should match the one on this page.
How to roll back
If the device stops working after the update: Device Manager → right-click the device → Properties → Driver tab → Roll Back Driver. If that button is greyed out, use the restore point you made before installing (Start → "Recovery" → Open System Restore).
