Can I boot in dock without external monitor turning on?

2017-08-02, 14:20 PM

I thought there would be a selection for this somewhere but I've searched and can't find it, so sorry if a solution is obvious!

 

Got a T470 and Ultra dock (not the USB one) with an external monitor connected via DVI and left in standby.

 

I want to boot on the laptop only, and then I can extend to the external screen as needed.  Is this possible? 

 

I was using a T61 in a dock before (with Windows10) and that defaulted to the laptop screen.

Hi Rory101,


Warm Greetings & welcome to Lenovo Community, happy to have you here.

As I understand that you have query regarding booting your ThinkPad T470 connected to a dock.

Enter in BIOS Setup utility & look for Boot Display Deviceand set it to ThinkPad LCD & update us how it goes.

 

I hope the information helped you

Please feel free to post in Lenovo Community Forums if you have any further queries!

 

Regards,
Prabhansh

Hi,

 

The bios is set as per the above.

 

I did a bit more testing and it works fine if left on the dock.   The issue arises if the T470 is removed and used away from the dock, and shutdown while off the dock.  If it's put back on to the dock and then turned on, the second monitor comes on.

 

I further discovered that this only happens if fast shutdown is enabled.  So a work around is to disable fast shutdown.

 

 

By the way - I couldn't log back in with my old Rory101 user name.  The system demanded my email address (Rory...) but then said the user name was already taken.  Then when I chose a new user name it wouldn't let me use my Rory... email address!   I think something went wrong in the account linking with Lenovo ID.
