pressing the Space bar used to result in the PIN entry window opening. Now, nothing happens. The only way to open the PIN entry window is to do a mouse click. What changed; what setting must be changed to re-enable the Space bar?

I had an issue with Windows 11 on a Lenovo ThinkPad Edge E130 where the keyboard would not respond on the lock screen after resuming from S3 sleep.
Symptoms:
The TrackPoint started working after a few seconds.
An external USB keyboard showed the same behavior, so this was not a hardware problem with the internal keyboard.
Alt+Tab had no effect.
Interestingly, when I clicked the magnifying-glass/info icon on the Windows Spotlight image and Windows switched to the Windows Hello PIN prompt, keyboard input immediately worked normally.
System details:
Lenovo ThinkPad Edge E130
Windows 11
BIOS H4ETA0WW 2.60
Traditional S3 sleep
Synaptics Pointing Device
Synaptics driver version 19.0.17.2
During troubleshooting I found that stopping the Synaptics background processes SynTPEnh.exe and SynTPHelper.exe made the problem disappear. This pointed to the old Synaptics software rather than the keyboard, PS/2 controller, BIOS, chipset or Intel Management Engine.
Solution:
I updated the Synaptics driver from:
19.0.17.2 → 19.0.17.107
With Synaptics driver 19.0.17.107, the problem is resolved. After resuming from S3 sleep, the keyboard now responds normally on the Windows lock screen, while the Synaptics/TrackPoint functionality continues to work.
So if you experience a similar issue on an older ThinkPad or another system using an older Synaptics driver — especially if the keyboard appears dead on the lock screen but works once the Windows Hello PIN dialog is displayed — check the installed Synaptics driver and SynTPEnh.exe.
In my case, updating the Synaptics driver to 19.0.17.107 was the fix.I had an issue with Windows 11 on a Lenovo ThinkPad Edge E130 where the keyboard would not respond on the lock screen after resuming from S3 sleep.

Hi,
As far as I know, recent updates have not affected any functionality on the lock screen. Pressing any key should still dismiss the lock screen background and show the PIN or password prompt. I recommend fully restarting your device, as this may simply be a temporary glitch. Once you login to your device, press Ctrl + Alt + Del then press Ctrl + Left-click on the power button. Click OK to perform an emergency restart.

There is no specific information in the provided context regarding changes to the functionality of the Space bar in Windows 11 or settings that would affect the PIN entry window. If the Space bar previously opened the PIN entry window and now does not, it may be due to a change in system settings or a software update that is not documented in the context. I recommend checking your keyboard settings or any recent updates that may have affected input behavior. Additionally, you may want to ensure that your system is fully updated and to look for any relevant settings in the accessibility options or keyboard settings in Windows 11.
