Lenovo E40-70 Drivers for Windows 7 (32-bit & 64-bit)

, ,

Page reviewed: October 12, 2026. Driver releases listed below are legacy packages.

Download legacy Windows 7 drivers for the Lenovo E40-70, including audio, chipset, graphics, wireless LAN, Bluetooth, touchpad, card reader and USB 3.0.

The Lenovo E40-70 was offered with different hardware configurations. The packages on this page link to Lenovo-hosted installers, but not every driver applies to every unit. Use the Windows edition selector and confirm your hardware before installation.

Quick installation tip: install the Intel chipset package first, restart, then add the graphics, audio, network and input-device drivers as needed. Update the BIOS only when necessary and after reading Lenovo's instructions.

Before downloading

  • Check your system type: open Control Panel > System and confirm whether Windows is 32-bit or 64-bit.
  • Identify optional hardware: open Device Manager and check the exact Wi-Fi adapter, graphics devices and fingerprint reader. Choose the matching vendor package rather than installing every alternative.
  • Keep an offline copy: if networking is unavailable, download the required package on another computer and transfer it by USB drive.
  • Windows 7 security: Microsoft support for Windows 7 ended in January 2020. For internet-connected everyday use, consider a supported operating system where hardware and software compatibility allow.

Only the selected operating-system list is shown. Download buttons open the original Lenovo-hosted installer.

Recommended installation order

  1. Intel Chipset Driver, then restart Windows.
  2. Intel Video Driver for the matching system type. Add AMD Video Driver only if Device Manager shows AMD graphics.
  3. Realtek Audio Driver.
  4. Realtek LAN and the matching Wi-Fi/Bluetooth driver, if those devices need drivers.
  5. Card reader, touchpad, fingerprint software and USB 3.0 as required.
  6. Optional Intel Wireless Display and brightness patch only if you use or need those features.
  7. BIOS update only when there is a clear reason to do so; connect the AC adapter and follow Lenovo's instructions exactly.

How to choose the correct driver

Wireless LAN and Bluetooth

In Device Manager, expand Network adapters and identify the Wi-Fi device. The multi-vendor WLAN package covers Realtek, Atheros and Broadcom variants; the separate Intel WLAN package is for a compatible Intel adapter. The Bluetooth packages are also split by Windows architecture and include several possible adapter vendors. Do not install both choices automatically.

Graphics

Choose the Intel video installer that exactly matches Windows 7 32-bit or 64-bit. The AMD package is optional and should be used only when your particular E40-70 has AMD graphics. If you are unsure, inspect Display adapters in Device Manager before installing.

Touchpad and fingerprint reader

The TouchPad package lists Synaptics and Elan support. Fingerprint software is useful only for a configuration with a supported fingerprint reader. Skip that package if the laptop has no fingerprint hardware.

Common issues

  • Installer says the device is unsupported: check the Windows bitness and identify the device vendor in Device Manager.
  • Wi-Fi still does not work: install the matching network driver using Ethernet or a USB transfer; restart after installation.
  • Screen brightness keys do not work: install the applicable Intel graphics driver first and consider the brightness patch only if needed.
  • Touchpad or card reader is missing: verify the device appears in Device Manager and install the corresponding package.
  • BIOS update concerns: do not interrupt power during an update. Do not flash BIOS as a routine step or use a package meant for another model.

Lenovo E40-70 Driver FAQ

Are these drivers compatible with all Lenovo E40-70 laptops?

No. Exact components can vary by configuration. Match each package to the installed Windows architecture and hardware IDs before installing.

Why are there separate 32-bit and 64-bit Bluetooth and Intel graphics downloads?

These are different installer packages for different Windows architectures. Download the one that matches your installed Windows edition.

Why is the Bluetooth package listed as 840.6 MB?

Lenovo's catalog lists the legacy multi-vendor Bluetooth packages at 840.6 MB. Check the package details on Lenovo Support before downloading if the size or applicability looks unexpected.

Should I install the BIOS update?

Not necessarily. BIOS updates carry more risk than normal drivers. Review Lenovo's release notes and instructions first, confirm the exact model, and keep AC power connected throughout the update.

Can I use these Windows 7 packages on Windows 10 or Windows 11?

This page is specifically for Windows 7 packages. Do not assume compatibility with another operating system. Use Lenovo Support to look for packages intended for the operating system installed on your laptop.

More laptop drivers

Important: the Bluetooth installers in Lenovo's catalog are very large (840.6 MB each). Confirm the Windows architecture and Bluetooth adapter before downloading. Some optional utilities may be unnecessary for your system. All package links lead to Lenovo's domains; file availability may change over time.
