Hi there, New to the forum, doing lots of reading, but can't seem to figure out why - when I upgraded the software for my 8520 - that I now no longer have a keyboard lock icon... Any suggestions? Cheers, A.

Correct, that is the way the upgraded OS release works.

You can set a password to lock the device and regain the lock icon, or use the 'a' key to go to standby or the top edge button for standby.

Thanks.
