T450S w/ lid closed not going to sleep automatically after eject from UltraDock

2017-03-07, 17:37 PM

Hello all,


I currently have an issue with at least 2 users...


When working on a Win10 T450s laptop, docked to an UltraDock with an external monitor while the laptop lid closed, ejecting the laptop(with lid closed but computer on) from the dock does not cause the laptop to automatically go to sleep.


I have all Windows 10 settings configured to sleep when it detects the laptop lid as closed.


This can be a real problem if the user thinks the laptop is going to sleep automatically and puts in their laptop bag with the laptop on, and potentially cause overheating issues and damaging the laptop.


Is there a setting I'm missing or is this a bug?


For time being I'm instructing users to manually put their laptop to sleep prior to undocking.


Thank You,
