Helix can't boot without a 2nd monitor attached

Hi,

 

I maintain a Helix (36984RU) that gets used for presentations.  It will not boot to Windows without a second monitor attached.   I can hear the fan spin up and the unit gets warm, but the screen remains blank.  The only thing I can do is to shutdown by holding down the power button.

 

When booting with a 2nd monitor or projector attached, the startup Lenovo logo appears on the 2nd screen and the laptop screen remains blank.  When the Windows login screen appears, it appears correctly on the laptop screen.  I've checked the Windows Screen Resolution page and it correctly shows the laptop monitor as the primary monitor.

 

This issue presents itself whether or not I disconnect the 2nd monitor prior to shutdown/restart, or whether I remove the 2nd monitor before restart.  It also does not make a difference if I start in tablet or docked mode.

 

I've updated the BIOS to version 1.29 and have checked that the boot display device is set to Thinkpad LCD, and not either of the two displayport options.

 

Any tips on this would be greatly appreciated,

Thanks!
