Keyboard and Touchpad stopped working - driver errors - can't update? | HP Omen 15

[QPMLiam]

Hi,

So I was working on the computer when it locked up and crashed . Upon restart Windows 10 updated. Once booted the keyboard and Touchpad stopped functioning.

The keyboardand Touchpad work within the BIOS and HP Diagnostics but not Windows 10.

I have an external mouse working in Windows but an external keyboard doesn't. On screen keyboard life ftl.

These issues are obviously driver related but I can't roll back the Keyboard driver and rolling back the mouse driver does nothing. Update showed errors but I was able to update eventually, to no change.

I tried downloading from the HP support site but install changed nothing . Uninstall and reboot did nothing.

Device Manager returns this error for the Touchpad:

This device cannot start. (Code 10)

Insufficient system resources exist to complete the API.

And this error for the Keyboard:

Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)

HALP ME.

Have you attempted to remove and reinstall the keyboard/touchpad drivers from the device manager?

While you respond to that, here's what you need to know and do:

The fix suggested in this section references terms like device and class filter drivers.
If you want to know more about those drivers:

1. Did you notice this error code after installing certain software? If so, uninstall that software and reboot the system. If the issue is not fixed, go to the next step.
2. In Device Manager, uninstall the driver. Right-click the device node showing the error and select Uninstall. From the Action menu, select Scan for hardware changes. This will let the system reinstall the drivers for the device. If the error code 19 issue is caused by a device filter driver, then reinstalling the driver might resolve the issue. If the issue is not fixed, go to the next step.
3. Determine whether a class filter driver is causing the issue.

a. In Device Manager, right-click the device node showing the error and select Properties.
On the Details tab, get the class name of the device as shown in this image for the HID-compliant mouse device:
 

 

b. Open registry editor (regedit.exe). Find the class key in the registry by walking the list of GUIDs under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class. For each GUID see if the class name matches the one you noted in the previous step.
 

c. Check whether the registry key has any UpperFilters or LowerFilters entries. In the preceding image, the value “mouclass” value indicates the name of service. There might be more than one service listed as filters as shown in this image.
 

d. For each value listed in UpperFilters, determine whether a matching service key exists in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services registry key. In this image, the mouclass service exists and you can see service details on the right side.
 

e. If the service exists, determine whether the driver file exists in the path specified by the ImagePathentry.
 

f. If the service is not found in the registry or the driver file is not found, then the device fails with code 19 error. In this case, there is no matching service for the “testfilter” UpperFilter value.

After you have identified the class filter that’s causing the issue, there are two ways you can resolve the issue.

• Edit the UpperFilters or LowerFilters registry entry and remove the service that’s broken and reboot the system. In this example, I removed the “testfilter” value from UpperFilter and rebooted the system. This will fix the code 19 issue but this is not the ideal solution because you may lose functionality of that filter driver. If removing the filter doesn’t compromise the user experience, then this might be the best option.

• A software package might have incorrectly installed the filter drivers. To get the name of the provider of the software package, search the internet for the service name or the driver filename, you retrieved in the previous steps. From the provider, you might be able to identify the software package that you installed recently before or after the upgrading to Windows 8.1 or updating Windows 10. With that information, uninstall the software or find the latest update from the IHV/OEM Web site and reinstall it: Click here to find and install the same.
