If you are facing this problem on a Windows device, follow these solutions in order.
Disabling the device will not harm your computer, but it will render all peripherals attached to that I2C bus unusable. If your touchscreen stops working after disabling it, you will know exactly which device was responsible.
If you are seeing this error in Device Manager (indicated by a yellow exclamation mark), follow these steps to install the correct driver.
If you prefer to download the file manually, you must get it from your laptop manufacturer's support page (e.g., Dell, HP, Lenovo, ASUS) or Intel directly.
The identifier ACPI\80860F14 (often appearing as ACPI\VEN_8086&DEV_0F14 ) refers to the Intel SD Host Controller
. This hardware component is integral to the I/O subsystem of Intel's Bay Trail and Cherry Trail processor families, such as the Intel Atom Z3700 series Functional Overview
The primary role of this controller is to manage the interface between the operating system and SD (Secure Digital) storage
. In many budget laptops, tablets, and mini-PCs (like the Surface 3 or ASUS E202SA), it handles the internal eMMC storage
where the OS is installed, as well as external MicroSD card slots. Technical Details & Implementation

Understanding the ACPI\80860F14 Driver: A Guide to Intel SD Host Controllers Acpi 80860f14
If you’ve ever ventured into the Windows Device Manager to troubleshoot a yellow exclamation mark or a "Missing Driver" error, you might have stumbled across a cryptic hardware ID: ACPI\80860F14.
While it looks like a string of random gibberish, this identifier is a crucial piece of the puzzle for mobile computing. Here is a deep dive into what this hardware ID actually is, why it matters, and how to get it working properly. What is ACPI\80860F14?
To decode this, we have to look at the two parts of the string:
ACPI: Stands for Advanced Configuration and Power Interface. This is an industry standard that allows the operating system to communicate with hardware for power management and configuration.
80860F14: This is the specific Plug-and-Play (PnP) ID. In the world of hardware, 8086 is the vendor ID for Intel, and 0F14 identifies the specific device.
Specifically, ACPI\80860F14 corresponds to the Intel BayTrail SD Host Controller. Where is this hardware found?
This hardware ID is almost exclusively found in tablets, 2-in-1 laptops, and ultra-low-power netbooks powered by Intel Atom Z3000 series processors (Bay Trail). Because these devices often use eMMC storage (an embedded MMC card) instead of a traditional SSD or Hard Drive, they require this specific controller to manage data flow between the processor and the storage/SD slot. Common Symptoms of a Missing Driver
If the driver for ACPI\80860F14 is missing or corrupted, you will likely notice one or more of the following issues:
Unknown Device in Device Manager: You’ll see "Unknown Device" under the "Other Devices" category.
SD Card Slot Not Working: You insert a MicroSD card, but the computer doesn't react. If you are facing this problem on a
Storage Performance Issues: Slow read/write speeds on the internal eMMC drive.
Power Management Issues: The device fails to wake up from sleep properly or the battery drains rapidly because the ACPI interface isn't managing the power states correctly. How to Install the ACPI\80860F14 Driver
Fixing this issue is usually straightforward, but the method depends on your device manufacturer. Since this is an Intel-specific component, you generally have three paths: 1. The Intel "SOC" Driver Package
Because this device is part of a "System on a Chip" (SoC) architecture, you rarely find a standalone driver for just the SD controller. Instead, you need the Intel Atom Processor Z3000 Series Driver Framework (often called the SoC Center or Intel Chipset Device Software). 2. Manufacturer-Specific Drivers
The most reliable way to fix this is to visit the support page for your specific device (e.g., Lenovo, ASUS, HP, or Dell). Search for your model number. Look for "Chipset" or "Platform" drivers.
Download the package labeled Intel Sideband Fabric Device or Intel BayTrail Chipset Drivers. 3. Windows Update
Sometimes, Windows Update fails to categorize this driver automatically. You can force a search by: Right-clicking the Unknown Device in Device Manager. Selecting Update Driver. Choosing Search automatically for drivers.
If that fails, click Search for updated drivers on Windows Update. Often, it will be tucked away in the "Optional Updates" section. Manual Identification Tip
If you are struggling to find the right file, you can verify the ID yourself: Open Device Manager.
Right-click the device with the error and select Properties. Go to the Details tab. Download and install the driver, then restart your computer
Select Hardware Ids from the dropdown menu. If you see ACPI\VEN_8086&DEV_0F14, you have confirmed you are looking for the Intel SD Host Controller.
The ACPI\80860F14 is the bridge that allows your Intel Atom-powered tablet to talk to its internal storage and SD card slots. If you're seeing this error after a fresh install of Windows 10 or 11, simply downloading the Intel SoC Driver package for your specific device model will typically clear up the error and restore your device's performance.
Are you currently seeing this as an "Unknown Device" in your Device Manager, or is the SD card slot itself not functioning?

The text string "ACPI\VEN_8086&DEV_0F14" (often shortened to Acpi 80860f14) refers to a specific hardware component in Windows Device Manager, usually appearing as an "Unknown Device."
This ID belongs to the Intel Power Management Controller (PMC), which is part of the Intel Atom Processor E3800 Series (Bay Trail) chipset.
Windows does not natively include generic drivers for every embedded Intel I2C controller. The driver required is the Intel(R) I2C Host Controller driver, which is part of the Intel CHT (Cherry Trail) or BYT (Bay Trail) I2C Driver Set.
If you see ACPI\80860F14 flagged as an unknown device, it means:
