Windows 10: Laptop with Docking Station and Multiple Monitors - Laptop Screen does not come back after...

When the power - screen timeout is reached all of my screens turn off. This is expected, and I have this enabled even when plugged in so that I can leave my computer on at night (sometimes with a long job running), without creating unnecessary glow in the bedroom or study.

However, when I move the mouse, or keyboard to get the screens back on, the primary/laptop screen does not come back - only the two extended/external displays come back on. The primary taskbar appears on the monitor that was Monitor 2, and the mouse cannot scroll into the space where Monitor 1 used to be.


What's up with that?

External monitors through both docking station and laptop ports

I recently got a new laptop through work - an HP EliteBook 840 G3. My current setup that I had been using at my desk was 3 external monitors plus my laptop screen. I had two monitors plugged in through the docking station via VGA and DisplayPort and the
third monitor I plugged into the VGA port on the laptop itself. This worked with my old laptop but with this new one it doesn't detect a monitor plugged into the laptop port when it's docked. I have tried looking through video settings with no luck. Windows
says my drivers are up to date and I've downloaded and installed the latest drivers for the docking station itself (it's the same docking station).

Would anyone have any advice for getting this setup working?

 

Laptop goes to sleep after undocking it from the station

Power troubleshooter came up with nothing.

Here is what I mean by machine does not come back up. Step by step process of what happens:

• Computer is on an plugged into docking station.
• I press the eject button on the docking station and the laptop is released. (Note I have also pressed the power button on the docking station first which makes the screen go black, but that does not change the rest of the flow)
• Take laptop out and leave out overnight.
• Come back in the morning plug laptop back into docking station
• Power light on laptop is slowly blinking red
• Move mouse and type on keyboard - nothing happens
• Press power button on docking station - nothing happens
• Open laptop lid (while still in docking station) - nothing happens
• Press power button on laptop - nothing happens
• Press every key on laptop keyboard (including function keys) - nothing happens
• Light is still blinking slowly on laptop all monitors are black
• Press power button on docking station (or laptop) and hold down for 10 seconds - power light stops blinking
• Press power button again - laptop boots. When I log-in all applications that were open are now closed and I get warning about unsaved data when I open applications.

 

External display with laptop and docking station

I have a Lenovo T440p laptop and docking station with a Dell external monitor. When I am using my laptop in the docking station I use both screens and select "extend this display" in the display settings to activate the external monitor. Heres my problem.
When I remove my laptop from the docking station it reverts to using one or the other displays when returned to the docking station, meaning it may be my laptop or it may be my external monitor. Windows seems to decide on its own which one I get to use so
I have to go into display settings nearly every time and select extend these displays to use both monitors. Its becoming time consuming and annoying. Why wont it remember that I am using 2 displays. I am running windows 10. I have asked our IT guys to fix
it but after weeks of asking and not getting any results from what they try a have given up hope. I had a different laptop, same brand and model that didnt display this behavior when returned to the docking station.
