Windows 10: Screen upside down when portrait, fine when landscape?

I've got a kind of weird bug.

I have an Asus Book Flip TP500LN (like a Lenovo Yoga but with bigger screen and Nvidia 840m) and although it automatically switches to tablet mode when flipped just fine, if I rotate to portrait the screen is flipped. If I hold it in landscape the desktop stays right side up even if I rotate it 180 degrees, but 90 and 270 degrees has the desktop upside down. It worked fine before.

Amazing!!! I had pulled my hair for 2 days. I can confirm that this works also.

Asus and Microsoft tech support came with Mickey Mouse suggestions, InvenSense didn't wanted to talk to me.

I assumed that the new driver provided by Microsoft update was "better" ver. 84.90.1.19 instead of the original from Asus 84.90.1.4 . I hope that Microsoft does not forcefully push a wrong driver again.

Thanks circecomputers... you rocks...

I have an Asus flip tp500la, and when I rotate to portrait my screen is upside down. If I use Ctrl Alt arrows, it will rotate to where I want and as soon as fliplock kicks in it turns upside down again. I have installed the windows 8.1 Invensense drivers
to no avail. Any ideas would be appreciated.

 

I am having the same issues on my wife's Asus Flipbook TP500LA. Her's is using the Intel integrated graphics driver and it has the most up to date drivers for that and the sensor suite. I have tried uninstalling the sensor drivers and updating them again but it still does not work. I remember reading something about this on Yoga systems but the answer was from a year or so ago and it involved editing registry entries in Windows 8. I was going to try it but I have not been able to find it since I first ran across it. Hopefully it is just a driver issue and it gets an update soon, or someone finds a solution for us.

 

I'm thinking this will be common to most Book Flips, if not just the TP500* series. I'm hoping it's fixed automatically in an update.

I did send a technical support ticket to Asus though.

 

(SOLVED)I DID IT!. ASUS techs are useless. Don't bother calling them or Microsoft as I did both with no success.
Here's the fix. This is for ASUS TP500LA and maybe others. Get to CONTROL PANEL and Click on DEVICE MANAGER. Scroll or look down until you find SENSORS under sensors the first entry you see will say IVENSENSE SENSOR COLLECTION. This is the problem! You can't rollback the driver because that option is greyed out. Here's the work around to rolling back the driver: Double click on IVENSENSE SENSOR COLLECTION >Click on the DRIVER TAB>Click on UPDATE DRIVER>Click on BROWSE MY COMPUTER FOR DRIVER SOFTWARE>Click on LET ME PICK FROM A LIST OF DEVICE DRIVERS ON MY COMPUTER>2 drivers should show up >Choose the older one IVENSE SENSOR COLLECTIONS VERSION 84.90.1.4[4/9/2014]. ***MAKE SURE YOU SELECT THIS DRIVER AND NOT THE NEW 2015 DRIVER.** Click NEXT wait for the OLD driver to install and VOILA your problem is solved!

 

That worked! Thank you.

I had done a clean install so I downloaded the driver and pointed the updater to the folder I extracted it ti.
