This historical archive may be incomplete. Release dates refer to the packages, and do not mean a driver is current. Use Lenovo Support to check compatibility and current availability.

Choosing drivers for the Legion Y540-15IRH

This page covers the Legion Y540-15IRH, machine type 81SX. Lenovo lists the Y540-15IRH-PG0 separately as type 81SY. Check that exact designation before choosing a package; the shared Y540 name does not establish compatibility.

Match the package’s supported models and Windows version. Lenovo’s LAN package DS539654 names the regular Y540-15IRH and lists Windows 10 64-bit, with a notice recommending version 1809 or later. The separate PG0 LAN package DS539670 names Y540-15IRH-PG0 and specifies Windows 10 64-bit version 1909. Use those compatibility lists to choose, rather than assuming that a newer-looking PG0 download replaces the regular model’s package.

Read the BIOS instructions before installation. Lenovo’s BHCN45WW README explicitly includes both variants and lists Windows 10 64-bit. It asks you to record changed BIOS settings because they may need restoring, verify the platform in the installer, and avoid powering off or restarting while flashing. The shared BIOS does not make every driver interchangeable.

Sources checked 3 October 2026. This is a verification date: the BIOS README is dated 20 May 2022, not a new 2026 release.
