Rotation Lock / Rotation Sensor Not Working (Lenovo Yoga 2-in-1)

I've got a Lenovo Yoga 700-11ISK that I've reformatted and reinstalled with Windows 10 Pro. I've been unable to get the rotation lock / rotation sensor working, which seems to be a very common problem. However, none of the common solutions has seemed to fix the issue. Below is a detailed list of everything I’ve learned. Note that whenever I refer to "Tent Mode," I mean the device's screen is physically rotated (‘folded back’) more than 180 degrees. Don’t confuse this with "Tablet mode," the software-based switch available in the Win10 Action Center; when I say "Tent Mode," I refer only to *physically* folding back the screen.

First, let's establish how it behaves on the factory image (i.e. the copy of Windows that comes with the system). These are the desired/expected behaviors, which I’m listing point-by-point for comparison to how it mis-behaves on my fresh Windows 10 Pro install:

1) In Tent Mode, "Rotation Lock" is available in the Action Center; otherwise, it's greyed.
2) In Tent Mode, "Lock rotation of this display" is available in System->Display settings; otherwise it's greyed.
3) In Tent Mode, the “Allow the screen to auto-rotate” checkbox in the Display control panel is available; otherwise it’s greyed.
4) In Tent Mode, the physical rotation lock button works; pressing it shows a “auto rotate on/off” OSD. Otherwise the button has no effect.
5) In Tent Mode, registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\AutoRotation has Enable=1; otherwise, Enable=0. Even if you set it manually, it gets overridden to this value on reboot, etc.
6) In Device Manager, detecting changes to and from Tent Mode seems to be handled by "Human Interface Devices/GPIO Laptop or Slate Indicator Driver" & "System Devices/Intel® Serial IO GPIO Host Controller - INT344B." Removing either stops it from detecting Tent Mode changes.
7) In Device Manager, detecting actual screen rotation (when in Tent Mode) seems to be handled by "Human Interface Devices/I2C HID Device" (9D60), "Sensors/HID Sensor Collection v2," and "System devices/Intel® Serial IO I2C Host Controller - 9D60." Disabling any of these 3 disables rotation-sensing / rotation lock options (when in Tent Mode).
8) If you disable the "YMC" service, rotation lock becomes available in 1-4 above, regardless of Tent Mode (aka it's always available).
9) If you disable the "SensrSvc" service, aka "Sensor Monitoring Service," all of the rotation lock options 1-4 above become unavailable/greyed, regardless of Tent Mode (aka it’s always unavailable).

Again, it's only Tent Mode (aka physical rotation of the screen) that makes rotation lock work; toggling "Tablet Mode" in the Action Center or answering “Yes” when prompted to switch to Tablet Mode is irrelevant.

Now for direct comparison, here’s how it behaves on my fresh-installed copy of Windows 10 pro:
1-5) Regardless of Tent Mode, these options are all greyed, the button has no effect, and the registry key has Enable=0.
6-7) Each of these drivers are installed & working in the Device manager, and are of the same date & version as in the factory image.
8) With the YMC service running, moving the laptop into Tent Mode it will prompt you to change to Tablet Mode – indicating that its “Tent Mode” sensor is functioning. If you stop the “YMC” service, rotation lock remains unavailable in 1-4. NOTE the difference: on the factory image, stopping YMC makes all the rotation lock options become available; here, they always remain unavailable regardless of this service.
9) SensrSvc is set to Automatic, and running. Stopping/restarting seems to have no effect.
10) The 'Sensor List' app (installed from app store) shows the Inclinometer properly reading changes to the system orientation.

Notice in particular that stopping “SensrSvc” on the factory image essentially makes it behave like my new/problematic system: whereas all the “Rotation Lock” stuff is supposed to be available while the tablet is physically in Tent Mode, it always remains unavailable. However, all the relevant drivers seem to be installed and of the same versions; all the services in question seem to be installed and running; and all the sensors are provably “sensing.” There are 2 sensors involved: 1) The one that senses when we switch to Tent Mode and 2) The one that senses screen rotation. I know #1 is working because when YMC is running, Windows prompts to enter Tablet Mode. I know #2 is working because ‘Sensor List’ can read orientations from the Inclinometer.

I’ve spent a crazy amount of time on this and seem to be up against a wall. If anyone can tell me how to get this rotation sensor working (aka how I can get the “rotation lock” options in 1-4 not to remain greyed when I enter Tent Mode), I’d be very appreciative.

 

Rotation Lock / Rotation Sensor Not Working (Lenovo Yoga 2-in-1)

Manual rotation via the display settings & via the keyboard hotkeys (i.e. ctrl+alt+up/down/left/right) does work; the issue is just that auto rotation via the sensor doesn't (and of course, auto rotation lock is always unavailable).

 

Auto Screen Rotation on Lenovo Flex 2 14

Hi,

Thanks for responding. I followed steps suggested by you but this is the end result. There is no 'Allow the screen to auto rotate'
option on the screen as you see in the screenshot.

Plus, as you asked for, my laptop model number is Lenovo Flex 2-14 (20404).

Kindly resolve this issue asap. It is so irritating to have a facility and not using it cuz of some windows issue.

best,

Nikhil
