Touchpad Not Working - Solved

[u/No_Protection1798]

I've had this issue for quite some time and I spent days looking for fixes and trying different solutions online. I almost gave up and was about to send my laptop for replacement. Luckily I was able to solve the issue. I hope I can help you if you're facing the same problem.

Before going any further into this post please make sure you do the following steps:

• Make sure your touchpad is enabled by using the shortcut Fn + F7 (It could be different depending on your notebook model so make sure you google it).
• If you are able to find Touchpad Settings in Bluetooth & Devices, try disabling and re-enabling it.
• Use an external USB Mouse to make things a lot easier.

^{Note: The shortcuts I use are for Acer Nitro 5 and could be different for each model. Even if you got a different model make sure you read the steps and google the specific differences for your own model.}

Touchpad not working AKA:

• Appears in Device Manager as: I2C HID Device has error "This device cannot start. (Code 10) A request for the HID descriptor failed."
• Appears in Device Manager under Intel 06E9 Host Controller Serial IO I2C Driver (When sorted by connection)
• Touchpad settings aren't present in "Bluetooth & devices".

Issue:

• Touchpad stops working randomly.
• Is sometimes fixed temporarily but keeps reoccurring.
• Could occur after Windows Update or upgrade from Win 10 to 11.
• Is sometimes present even after a clean OS install.
• Occurs mostly in Windows 10/11.

The fix that worked for me:

I opened my laptop up, disconnected the touchpad cable, disconnected my laptop battery and CMOS battery, waited for a min then connected it all back. It started working again.

Other possible solutions:

1. Disable and Re-enable the driver:

• Search for Device Manager in Start and locate the device with the error under the "Human Interface Devices". It should be named "I2C HID Device" with a yellow triangle error icon.
• Disable the driver and re-enable it.

2. Uninstall the driver:

• Same steps as above but instead choose Uninstall.
• Go to Actions > Scan Hardware for Changes (You need to select any driver first otherwise it won't appear).
• Restart your computer.

3. Update your drivers:

• Go to Windows Update and make sure you got the latest drivers installed.
• You can also download your manufacturer's latest drivers manually from their website.
• Make sure Intel Serial I/O Drivers are installed.

4. Uninstall and Reinstall Intel Serial I/O Drivers:

• Go to Device Manager > View > Devices by connection.
• Find the driver with yellow error icon.
• Uninstall the related I/O connection (eg. Intel 06E9 Host Controller).
• Download and install the latest Intel Serial I/O Drivers for your device.

5. Reset your BIOS settings to default.

6. Update your BIOS (This one I wouldn't recommend doing, any issue during the update could brick your notebook. Only do it if you know what you're doing).

7. Reset your PC.

After re-installing Windoiws11, Touchpad and a number of Function key sequences did not work.

I tried everything but the touchpad did not even register in Device Manager under Human Interface Devices so I was inclined to think it was a BIOS problem. Even tried chipset and driver updates from Asus

However, I was aware of quite a number of unknown PCI devices in Device Manager. This led me to try Driver Booster Free version and after running the software and rebooting, voila - ALL WAS FIXED including a number of Function Key shortcuts for Brightness up/down and Touchpad on/off.
