autorotation does not work after update 8, 1 wind - W510

I have a tablet with docking station and 32 GB w510

the autorotation feature does not work after update to 8.1 windows. the lock button does not work and there is no option for the autorotation lock in the settings.

I ve installed the latest driver form acer download page and Windows update.

then I tried a clean install of windows 8 and yet once installed can I 8.1 and it still does not work.

What can I do?

PS the camera does not work

-solution for me! ----

I don't know what happened, but I'll tell you what I did not last:

I have the European version of Windows 8.1 N(without Media Feature Pack)

  1. reinstalled microsoft silverlight.
  2. search for update---> silverlight update available!---> installed!
  3. reset
  4. installed the 'Media Feature Pack for N and KN from Windows 8.1 versions"from here: http://www.microsoft.com/en-us/download/details.aspx?id=40744
  5. reset
  6. Search again---> new available updates updates---> installed
  7. reset!

now, camera, autorotation and all the apps work for me. I hope this will help you

Best regards
