Please follow the steps below.
Step 1: Reinstall the I2C HID Device
This often forces Windows to bind the correct driver.
In Human Interface Devices
Use arrow keys to highlight I2C HID Device
Press Shift + F10
Select Uninstall device
Press Enter
If asked, do NOT check “Delete the driver.”
Restart the laptop
After reboot, check if Mice and other pointing devices appear.
Step 2: Install the missing Intel Serial IO driver (CRITICAL)
Without this, the touchpad will never work.
Go to your laptop manufacturer’s support website
Download and install:
Intel Serial IO driver
Chipset driver
Restart after each install
Step 3: Install the correct Touchpad driver
Depending on your laptop, it will be one of these:
Synaptics Touchpad
ELAN Touchpad
Precision Touchpad
Install it after Serial IO and Chipset.
Step 4: Final check
After reboot:
Device Manager should show:
Mice and other pointing devices
HID-compliant mouse or Precision Touchpad
Touchpad settings should appear in:
Settings → Bluetooth & devices → Touchpad
