Windows 10: keyboard option is gone from the device manager

I am using Lenovo ideapad 330 and in this the keyboard driver is not listed in the device manger. the keyboard option only shows up when I join the wired keyboard. I have tried using the registry also but does nothing. on the human interface devices there is the exclamation sign on the ELAN EzTouchFilter

This device cannot start. (Code 10)
A required I2C connection and/or interrupt resource was missing.

Keyboard driver gone from the device manager after windows update

Hi Andre,

Thank you for your response.

I have tested the steps suggested and now I am able to see the keyboard into the device manager. However the keyboard it is still now working.

Also I have noticed that under the under the Advanced Recovery environment the keyboard it is working properly.

I have tried with the disable/enable and restart from the device manager. Also I have uninstalled and restarted the laptop but the issue still remain.

Could you please let me know if there is something else which could block the keyboard driver?

Thank you in advance.

 

Device Manager Un-Hiding Hidden Devices


When you connect a plug and play device, Windows Plug and Play manager detects it, finds and installs the driver. Device Manager lists the device with a solid icon.

The driver is only removed when you uninstall the device, not simply by disconnecting the device. When the device is disconnected, its driver is still installed. By default, Device Manager only displays connected devices. When you show hidden devices, note the Bluetooth icon you see is semi-transparent (not opaque). That indicates a "non-present" device. Sometimes also called a "ghost" device. The driver is still installed but the device is not currently detected (i.e. not connected).

Device can be disconnected when

• Device unplugged (e.g. removing a USB device)
• Turning a device OFF
• Disabling the device in BIOS (then windows won't detect it) or
• Device failure

So

• Check BIOS as suggested
• Check board connections
• Can b/t be turned off by a switch? or keyboard combination?

Also possible the b/t h/w failed
