No external Keyboard input from LENOVO ThinkPad

ソリューションが必要です

Hi

 

We have XPSP3 on Lenovo ThinkPad T430 laptops. Part Number (23561y3)

We are using GuardianEdge Framework and Client version 9.5.3

 

BIOS USB Settings are:

USB UEFI BIOS Support - Enabled

Always On USB - Enabled

Always On USB Charge in Off Mode - Disabled

USB 3.0 Mode - AUTO

USB Port - Enabled

 

The issue is:

 

If a USB Keyboard is attached to the laptop via a docking station and a user tries to authenticate at preboot there is no input from the keyboard.

If the External Keyboard is disconnected then the character entry goes through.

 

I see this has been an issue with other models of laptop but cannot determine if this laptop is also known to be affected.

 

Can anyone confirm if this is so?

Is there any way I can determine this through testing?

 

Any assistance is greatly appreciated.
