X1 Tablet CTRL-ALT-DEL No Win Button - How to get past CTRL-ALT-DEL at logon?

I received our first X1 Tablet this week and have found an issue related to this device's lack of a hardware Windows Button.  My organization's standard group policy enforces CTRL-ALT-DEL at login. When working in tablet mode (without the hardware keyboard connected), there doesn't seem to be a way to get past the CTRL-ALT-DEL screen.

 

On previous tablet devices, like the Lenovo Helix 2, you would simultaneously press the Power + Windows Button to replicate the CTRL-ALT-DEL entry.   I've tried pressing Power + the volume control keys (since those are the only other hardware buttons), but that doesn't do anything.  Apparently Microsoft uses Power + Volume-up on the Surface Pro 4 in order to solve this issue.

 

Does anyone have any ideas on how to get around this other than disabling the security standard requirement?  Does Lenovo have a driver or firmware update that can be installed to make the volume controls perform this task, like the Surface Pro 4 does?

I'm also very much interested in an answer here. We start to deploy this device widely and for an Enterprise it is common to have such security (CTRL+ALT+DEL) enabled. Is this something that can only be bypassed using Accessibility Features (if at all) or BIO authentication methods?

 

Thanks.

I have been looking for a solution to this issue as well. I have tried different programs and have come up empty on solutions.

This was working in BIOS 1.16 and 1.18, but it is no longer working now that I've installed the most recent BIOS Version 1.19:  http://support.lenovo.com/us/en/downloads/DS112372

 

It's interesting that in this newest BIOS version 1.19 they went back to ECP 1.07.   Perhaps reverting to ECP 1.07 is what has taken away the "Power Button & Volume Up" CTRL-ALT-DEL capability?
