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?
Solved! Go to Solution.

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?

This feature has been added in BIOS 1.16
UEFI: 1.16 / ECP: 1.08
- (New) Supported Power + Volume up button combination to notify "CTRL+ALT+DEL"
action to Windows OS.
Note: This combination works in OS environment only.
Note: Press and hold Power button. Then press Volume Up button within 1
seconds, then "CTRL+ALT+DEL" is notified to Windows OS.

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?

A BIOS with ECFW that restores CTRL-ALT-DEL functionality at login passed test and is being scheduled to be released.
When it becomes available, the BIOS with updated ECFW will be available here: http://support.lenovo.com/us/en/products/Tablets/ThinkPad-Tablet-Series/ThinkPad-X1-Tablet/downloads...
