Product: HP Pavilion x360 Laptop- 14m-dw0023dx
Operating System: Microsoft Windows 11

My elan touchpad input device stopped working and I got the error "Currently, this hardware device is not connected to the computer. (Code 45)." I tried the trick of uninstalling the driver and restarting my device but it has not reinstalled. I'm having trouble figuring out how to reinstall it when the device doesn't even show up in device manager or hidden devices anymore. I've tried finding drivers on the HP website but it doesn't show this exact driver in keyboard, mouse, and input devices. Still, I installed the drivers here just to be safe and it didn't work. 

To clarify as well, this didn't exactly pop up with windows 11. I had this problem in windows 10, then took my laptop for unrelated repairs to best buy and it seemed to be fixed somehow. Then downloaded windows 11 and it started happening again. Since then, this has happened once more but it seems to randomly fix itself - it had been working for months before now. I've similarly had the driver not reinstall as well, and again, it seemingly randomly popped back up on my laptop upon starting up one day. It'll be obvious when it's about to stop working too - the cursor gets kind of laggy and slow. 

EDIT: It's redownloaded now but still doesn't work, giving me the code 45 error. Any help?

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help,

I appreciate your efforts to try and resolve the issue. The last thing I can suggest try and restore the OS back to the factory default, which will isolate whether it’s a software or hardware issue. The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system. 

Hope this helps! Keep me posted for further assistance.
