Supported hardware IDs (5)

Compare with your device: Device Manager → right-click the device → Properties → Details → Hardware Ids. If one of the values above matches, this driver supports your hardware.

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 (64-bit) - if your Windows is different, look for another version further down the page.

  1. Download the file with the button above - it comes directly from Lenovo official catalog.
  2. Double-click the downloaded file and follow the prompts - the installer does the rest.
  3. 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).
