Lenovo B40-80 Drivers for Windows 7, 8.1 and 10

Looking for the correct Lenovo B40-80 drivers? This guide covers every official download for the B40-80, organized by Windows version, so you can match the right package to your exact setup instead of guessing. It includes Windows 10 (64-bit), Windows 8.1 (64-bit), and Windows 7 (32-bit and 64-bit).

Installing the correct driver restores hardware functionality and prevents the most common post-install issues on this model: missing Wi-Fi, no sound, an unresponsive touchpad, and "Unknown Device" entries in Device Manager.

Before you start: confirm your exact Windows edition and system architecture (32-bit vs 64-bit) first — installing a driver built for the wrong architecture is the single most common cause of failed installs on this model. See the "How to Check Your Windows Version" section below if you're not sure.

Recommended Installation Order

Installing drivers in the wrong order is a common reason components still misbehave after setup. On the B40-80, follow this sequence:

  1. Chipset driver (restart if prompted)
  2. Graphics driver (Intel and/or AMD, depending on your configuration)
  3. Audio driver
  4. LAN / Ethernet driver
  5. Wireless LAN / Wi-Fi driver
  6. Bluetooth driver
  7. Touchpad driver
  8. Card reader and camera drivers
  9. Remaining utilities (fingerprint reader, energy manager)
  10. Restart Windows and open Device Manager to confirm every device shows no warning icon

How to Check Your Windows Version and Architecture

Before downloading anything, confirm what you're actually running:

  • Press Windows + R, type winver, and press Enter — this shows your Windows edition and build.
  • Go to Settings → System → About to see whether you're on 32-bit or 64-bit (Windows 10/8.1).
  • On Windows 7, open Control Panel → System and check "System type."

Fixing Common Lenovo B40-80 Driver Problems

If something stopped working after a Windows reinstall or update, it's almost always a missing or mismatched driver. Typical symptoms and the fix:

  • No Wi-Fi: install the Wireless LAN driver matching your exact Wi-Fi chipset (Atheros, Realtek, Broadcom, or Intel — check Device Manager to see which one is installed).
  • No sound: install the Realtek Audio driver for your Windows version, then restart before testing.
  • Touchpad not responding: install the Elan or Synaptics driver matching your touchpad model.
  • Unknown Device in Device Manager: right-click it, open Properties → Details → Hardware Ids, and match that ID against the chipset, card reader, or Bluetooth drivers above.
  • Bluetooth missing after a clean install: install the chipset driver first, then the Bluetooth driver — Bluetooth often fails silently if the chipset driver isn't in place yet.

Downloading Drivers Safely

All links on this page point directly to Lenovo's own driver distribution domain (download.lenovo.com). Avoid third-party "driver updater" sites that repackage these files with bundled installers — there's no benefit to using them over the official package, and the added software is the actual risk. If you're ever unsure whether a file is genuine, check it against Lenovo's official support page for the B40-80 before running it.

Frequently Asked Questions

What Windows versions does this page cover?

Windows 10 (64-bit), Windows 8.1 (64-bit), and Windows 7 (32-bit and 64-bit).

Why is my Lenovo B40-80 Wi-Fi not working after installing Windows?

The wireless adapter driver is usually missing by default on a fresh install. Check Device Manager for the exact Wi-Fi chipset, then install the matching Wireless LAN driver from the table for your Windows version.

How do I fix no sound on the Lenovo B40-80?

Install the Realtek Audio driver listed for your Windows version, restart, and check that the correct playback device is selected in Windows Sound settings.

Why does Device Manager show an Unknown Device?

Windows couldn't match the hardware to an installed driver. Open the device's Properties → Details → Hardware Ids, and compare that against the chipset, card reader, or Bluetooth entries above.

Should I install the 32-bit or 64-bit driver?

Match it to your Windows installation, not your processor. A 32-bit Windows 7 install needs the 32-bit package even if the CPU supports 64-bit.

What should I install first on a fresh Windows install?

Chipset driver first, then graphics, audio, LAN, Wi-Fi, Bluetooth, and touchpad, in that order — see the installation order section above.
