The Intel(R) Q67 Express Chipset Family LPC Interface Controller - 1C4E is a device driver associated with the Low Pin Count (LPC) Interface of the Intel Q67 Express chipset. The LPC interface is a legacy bus interface used for communication with system components such as BIOS, TPM (Trusted Platform Module), or other low-speed devices. The driver facilitates proper communication between the operating system and the hardware components managed by the Intel Q67 chipset.
This driver is typically installed automatically by Windows when you install or update the Intel chipset drivers. However, if Windows fails to install it or the device shows up with an error in Device Manager, you can manually install or update the driver.
Steps to Install the Intel(R) Q67 Express Chipset Family LPC Interface Controller - 1C4E Windows Driver:
1. Check Device Manager for Errors
- Open Device Manager (Press Win + X and select Device Manager).
- Look under the System Devices section or Other Devices for a device named something like Intel(R) Q67 Express Chipset Family LPC Interface Controller - 1C4E. If there's a yellow exclamation mark, it indicates a driver issue.
2. Download the Latest Intel Chipset Drivers
-
Visit the official Intel Driver & Support Assistant or download the latest chipset drivers directly from the Intel Download Center:
-
The chipset driver package includes support for all the components that are part of the Intel Q67 chipset, including the LPC interface controller.
3. Install the Driver
-
If you have downloaded the Intel Chipset Device Software (INF update), it may come with an installer (.exe
file).
- Run the installer and follow the on-screen instructions.
- If you downloaded a zip file, extract it, and then follow the manual installation steps.
-
Manual Installation (if needed):
- Right-click the device in Device Manager (with the yellow exclamation mark) and select Update Driver.
- Choose Browse my computer for driver software.
- Point to the folder where you extracted or installed the chipset drivers.
- Allow Windows to search and install the appropriate driver.
4. Restart Your PC
- Once the installation is complete, restart your computer to apply the changes.
5. Verify Installation
- After the restart, check Device Manager again to ensure the device is listed without errors under System Devices.
- You can also check if the issue with the LPC Interface Controller is resolved by verifying there is no longer a yellow exclamation mark.
Additional Tips:
- Driver Conflicts: If the installation does not work, ensure that there is no other conflicting driver or hardware issue in Device Manager. Sometimes, outdated drivers or missing updates might cause issues with chipset components.
- BIOS Update: In rare cases, updating the system BIOS might help resolve chipset-related issues. You can check for BIOS updates on the manufacturer's website of your motherboard or laptop.
- Use Intel Driver & Support Assistant: If you are unsure about the correct driver version, Intel's Driver & Support Assistant tool can automatically detect and recommend the appropriate drivers for your system.
By installing the Intel Q67 Express Chipset Family driver, the LPC Interface Controller should function correctly, allowing proper communication with the chipset's integrated components.
