FileVault password not working from standby I have several users on my MacBook but have FileVault setup with only one uses, lets say it is called 'admin'. So when the MacBook goes into standby mode (hibernate) and the FileVault password is requested, the only user who can unlock it is 'admin'.

This used to work fine, but after reinstalling the MacBook this setup has stopped working. When the system wakes from standby, the 'admin' password isn't accepted. I am sure the password is correct, since I can use is fine when I start from boot.

I have already changed the password, but that didn't help.
I am running macOS Sierra with all the updates.

What is wrong and how can I fix this?
Seems the password is not the problem, but the keyboard is. After waking up from standby the keyboard and touchpad stutter, so some keys become missing when typing in the password.
