T430 and X230 go to blackscreen, no cursor when rebooted on dock, Win10
On at least three laptops, two T430s and an X230, I get a black screen after rebooting.
I get the initial Windows 10 splash screen, then the display goes black - no cursor, no display, nothing.
It only happens while on a docking station. It doesn't happen after a boot-from-power-off (cold boot) or wake from sleep. All laptops running Win10 with up-to-date drivers.
I'm guessing that it's a display driver issue. It only happens when the laptop is on the dock and the only active display is the external monitor (attached to the dock). If I have the laptop display on (lid open) and both displays are active, I don't get a black screen. I've tested it with multiple monitors, multiple docks, UEFI and legacy BIOS.
Any ideas? Anyone else experiencing this problem?

I'm had the same issue with my X230. Ended up going back to Windows 8.1 because of this.
It's either a display or power saving driver issue.
Only way I can recover is by pulling the Displayport cable out of the dock and plugging it back in. The machine is running and very much alive, just no video.
Power off and reseat the battery. That's how I "clear" the issue.
