Hello ASUS, I have bought this laptop in November 2019 .
ISSUE :
my integrated laptop keyboard is not working after I log into windows but the keyboard is working fine in boot, UEFI or in safe mode. the system automatically uninstalling the following driver:
in human interface devices section : ALL USB DRIVER
in keyboard section : HID KEYBOARD DRIVERS keeping PC/AT Enhanced PS/2 keyboard(101/102-Key) installed.
In ARMOURY CRATE the keyboard is not detecting
The bellow snap is when the driver is fine. Keyboard is working fine.(AS SOON AS I LOGGED IN)


Now as soon as I log into the system. after some time the driver were uninstalled automatically.



SOLUTION TRIED :
Uninstalled all the keyboard driver and human interface USB related driver(both in normal and safe mode)
Reset the system(using OEM recovery)
Wiped the SSD and re install the OS using external bootable USB driver
Tried plenty of Diver updater software to update the keyboard drivers
Tried uninstalling drivers while keeping only windows service enabled.
Also tried to uninstall all driver after running "set devmgr_show_nonpresent_devices=1" command in CMD Promt.
NOTHING WORKED. PLEASE HELP.
QUESTIONS :
why isn't there any keyboard driver in Human Interface Devices section ?
What would be the possible fix for this issue?

Hello sayantan.majee24,

When did this happened? After any update or modification?

Have you updated BIOS?

This thing is happening since 2 month. Yes I have updated BIOS. i have tried to roll back to older one..but nothing is fixing my problem..and also asus customer care is not caring about customers. They are just ignoring issue what I am facing

This issue keep coming back after some time. Every time I have to uninstall PS2 keyboard device and reboot. This is very frustrating, lots of my time is getting wasted in this. I have also updated BIOS and tried some things as mentioned in this post, unfortunately nothing is helping. Error that I saw in HID keyboard device: "Currently, this hardware device is not connected to the computer. (Code 45)"

Have you tried other keyboard?
