Hp Zbook x360 G5 Convertible touch screen not working after updateing bios to 01.33.00 Rev.A

[bobco631]

after updating the bios and upgrading windows from 10 to 11, I have lost all ability to use touch or pen, when this definitely worked prior to the update.

The same issue happened with me after updating bios to q71 ver 1.33,

Hi @bobco631  @mahmoud_ziko ,

Thank you for posting your query, I will be glad to help you.

That is a frustrating situation, and I appreciate you providing the specific details about the HP ZBook x360 G5 and BIOS 01.33.00 Rev.A.

The issue is likely that the BIOS update either disabled the touch/digitizer hardware interface or changed a configuration that the Windows 11 drivers cannot properly interpret.

Here is a comprehensive set of troubleshooting steps, starting with the most likely fixes for a BIOS-related touch issue:

1. Hardware & BIOS Checks

Since the BIOS directly controls hardware, this is the most important area to check first.

A. Hard Reset

A hard reset can sometimes clear temporary BIOS/hardware conflicts.

Turn off the computer completely.

Unplug the power adapter.

Disconnect any peripherals (docks, USB drives, etc.).

Press and hold the Power button for 15-20 seconds. This drains residual charge.

Plug the adapter back in and turn on the computer.

B. Check the BIOS/UEFI Settings

The BIOS may have silently disabled the digitizer.

Restart the computer and immediately press F10 repeatedly to enter the BIOS Setup.

Look through the menus (often under Advanced or Security/Device Security) for options related to Touch Screen, Digitizer, or USB/Input Devices.

Ensure that the touch/digitizer functionality is Enabled.

Save changes and Exit.

C. Run the Touch Screen Hardware Test

This test determines if the screen hardware is detected by the system firmware.

Restart the computer and immediately press F2 repeatedly to enter the HP PC Hardware Diagnostics UEFI.

Select Component Tests.

Select Touch Screen and run the test.

If the test runs and passes: The hardware is fine; the problem is with Windows 11 drivers/software (move to Section 2).

If the test runs and fails: The hardware interface is not working. The BIOS update is the likely culprit, and you should consider the BIOS rollback (move to Section 3).

If the "Touch Screen" option is missing: The BIOS update has completely hidden or disabled the touch hardware. You must attempt the BIOS rollback (move to Section 3).

2. Windows 11 Driver Troubleshooting

If the hardware test passed, the issue is Windows 11 driver-related.

A. Check Device Manager for HID-Compliant Touch Screen

Press Windows Key + X and select Device Manager.

Expand the Human Interface Devices section.

Look for "HID-compliant touch screen" (you may have more than one) and "Wacom Device" or similar digitizer entries.

If you find them:

Right-click and select Enable device (if it's disabled).

Right-click and select Uninstall device (do this for all touch/digitizer entries). Do not check the box to delete the driver software.

Restart the laptop. Windows should automatically reinstall the drivers.

If you DO NOT find them: Click View > Show hidden devices. If they appear, they are disconnected. If they still don't appear, the BIOS has disabled the hardware (move to Section 3).

B. Reinstall the Official HP Windows 11 Drivers

The ZBook G5 is a business/workstation model, and HP often provides specific drivers for the touch panel:

Go to the HP Support website for the ZBook x360 G5.

Select Windows 11 as your operating system.

Look for drivers under the Driver-Input Devices or Driver-Keyboard, Mouse, and Input Devices section.

Download and install the latest Wacom or Touch Screen driver available.

3. BIOS Rollback (If All Else Fails)

Since the BIOS update is implicated, the most effective fix may be to revert to the previous, working BIOS version.

Caution:

A failed BIOS rollback can brick your laptop. Only attempt this if the hardware test failed or the touch device is missing from Device Manager.

Find the previous working BIOS: Go to the HP Support site for your ZBook x360 G5, look at the available BIOS versions, and download the one immediately preceding 01.33.00 Rev.A (e.g., 01.32.00 or similar).

Rollback using the HP BIOS Update Utility: HP's update utility often includes an option to downgrade.

Rollback using HP BIOS Recovery:

Turn the laptop off.

Press and hold the Windows key + B key, then press and hold the Power button for about 3 seconds, then release the Power button while still holding Windows + B.

This should trigger the HP BIOS Update/Recovery screen. Follow the prompts to restore the previous version if it was backed up, or use a USB drive with the older BIOS file.

If a BIOS rollback doesn't work, this is a BIOS-level bug that HP needs to address with a subsequent fix. At that point, you must contact HP Support and specifically reference that the touch device is not working even in the UEFI hardware diagnostics after the 01.33.00 Rev.A update.

Hope this helps resolve your issue.

Having the same issue - anyone found a solution?

I checked in the BIOS diagnostics and the touch screen is not responding at all, so presume it is the BIOS update.  Given the warnings, I wanted to first check if anyone else had already attempted this and what the result was?
