phoffric, I suspect what you have there is an assumption by the manufacturer that when the laptop is folded, there's no reason to keep video on. &nbsp;It's easy for that to be interpreted by Engineering as &quot;when the laptop is closed, <u>no</u> video should be on.&quot;<br />

Did the site with the instructions show this particular model that you have working when the unit is folded?

one thing to note. &nbsp;there are 2 conditions where you have to set this. &nbsp;both on battery and on power. &nbsp;it is &nbsp;likely you set it for battery but not for while on wall power.<br><br>

I didn't have to prop the laptop lid. &nbsp;I restarted, and the external monitor acted as the single monitor. Thank you.

Have windows 10 on thinkpad laptop. followed some instructions to keep alive when I close the lid so that I can work on my external monitor. &quot;Do nothing&quot; is the setting. But when I close the lid, the screen turns off. Am I missing a step?

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.

This topic area includes legacy versions of Windows prior to Windows 2000: Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions including Windows Mobile.
