Quick Fix: No Rotation Lock visible after installing/upgrading Windows 10 (HP Stream)


Although the recent Windows 10 Build upgrade is largely without problems if you perform a clean install of Windows 10 on the HP Stream 8, you may encounter an issue where Rotation Lock, which toggles screen orientation to portrait and landscape,  is no longer a Quick Action option in Action Center/Notifications.
 

 
The recent November Windows Upgrade 10 installs all the necessary drivers for the HP Stream 8, including the Intel HD Graphics Control Panel, which actually has options for rotating the screen since the application treats the tablet display as any other display. However, accessing the Intel application is a nuisance in Tablet mode and is difficult to open if you're in Desktop mode without an input accessory such as a mouse or stylus.
 


Windows Update provides drivers for the Kionix G-Sensor, which handles the movement of the device. However, you would still need to either reinstall the Kionix driver or download the most recent version of the driver for the Stream 8 from the HP support site.

To resolve the lack of Rotation lock as a Quick Action:

1. In Desktop mode, tap Start > Windows > Run. Input devmgmt.msc.

2. In Device Manager, expand Sensor I/O devices and right-click Kionix KXCJ9 Accelerometer SPB. Click Disable.

 

3. Right-click on Kionix KXCJ9 Accelerometer SPB and click Enable.

4. Reboot the system and check if Rotation Lock appears as before as a Quick Action.

5. If Rotation Lock is still not available, download the updated 32-bit Kionix G-Sensor Enabling driver from the HP support site.

Note: As of this writing, the current version is 1.00 Rev.A.

 

6. Install the driver and reboot the system. Check if Rotation Lock is visible as a Quick Action.

Note: The sensor found in the HP Stream 8 is pretty awful compared to other tablets.  Reinstalling the Kionix driver added the Rotation Lock option back as a Quick Action on my HP Stream 8, but it took quite a few spins and turns on the tablet before the Windows 10 desktop actually rotated. I had to revisit Device Manager just to check if I had to re-enable the sensor a second time.

As a final note, it's best to install the Semtech SAR Sensor Enabling driver available from the HP Support site also. The driver will address leftover hardware components that the Windows 10 update/install didn't set up.
