m16 R1, issues with Keyboard/Usb Mouse and Bluetooth device driver errors
So as of this morning, my keyboard inputs aren't registering, and when I plug in my usb mouse, it briefly lights up and turns off and won't work. The touchpad is the only thing that seems to Function and the F1 key for Fans/Performance.
Ive gone into Bios and the keyboard functions fine there. It's as soon as i get to the windows login screen for my pin where all keyboard/mouse inputs stop.
Ive also noticed when I connect my dualsense, it connects in the Bluetooth settings but after a few seconds it shows driver error and shuts off.
My Bluetooth headset connects just fine. Ive checked for driver updates and bios updates and everything checks out there.
This all started after a Windows update yesterday evening and I had it shutdown after the update and only went back on this morning.
I'm not sure what else to try at this point as like I said, it functions in Bios and running diagnostics shows no erros either.

Please can you confirm the Make Model and OS, along with any configuration details like touch screen, backlit keyboard, SFF or tower etc etc.
Hi
Perhaps look to roll back the driver (s), or a restore point of 2 days ago?
Which Windows updates were done?
Kind Regards

It's an Alienware m16 R1 Laptop. Intel Core I7 if i recall. OS is Windows 11. I'm at work and won't be able to update everything. The keyboard also lights up in various ways and that light still functions correctly. No touch screen.
I'll have to check which windows update last rolled through once I get home. I haven't tried rolling back though.

So these were the most recent Windows updates. As far as I know drivers were not updated in terms of Alienware updates, Nvidia or Intel themselves.
The processor is a 13th Gen Intel(R) Core I7-13700HX.
Nvidia GeForce RTX 4070.
I also don't unfortunately have an option to rollback enough days either.

Since the keyboard works in BIOS and the issue started right after a Windows update, this sounds more like a Windows driver or update-related problem than a hardware failure.
If you can use the touchpad, try accessing Windows Recovery and booting into Safe Mode. If the keyboard and USB mouse work there, it may help narrow the issue down to a driver or software conflict.
You could also try uninstalling the most recent Windows update from Windows Recovery under Troubleshoot → Advanced options → Uninstall Updates. If you can't enter your PIN, you can access Recovery from the login screen by holding Shift while selecting Restart, using the touchpad.
Before making any changes, make sure you have your BitLocker recovery key available if device encryption is enabled.
If the problem continues, check Device Manager for errors under Human Interface Devices, USB controllers, and Bluetooth, and share the specific error codes.
Hope this helps!

Going into safe mode was one of the things I did try. I sort of followed a step by step guide on Dell's site at first. Despite that, it did not function in Safe mode either. The mouse was functioning in the whole Windows Recovery screens as well though when going through those options. I'll take another look at the Device Manager again, but there were no signs of errors but maybe I just need to open the properties of the actual drivers and see if there is any noticeable info there.
I'll also attempt to rollback the updates tonight after work and see if that changes anything.

So this error is for each of the Human Interface Devices. I tried deleting them and scanning for Hardware changes and they are brought back but with the same issue at hand.
Edit: I'm attempting to do a Windows 11 Update repair fix in hopes that maybe this is all it possibly needed.

So it seems I have figured out the issue. I simply had to do an Update Repair and everything now seems to be functioning prior to the update. Thank you to those who offered with help. Never personally ran into this issue before. Thanks again!
