From Win 8.1+, BIOS might use the new way to handle the power button, it's called intel virtual button.
BIOS should switch to the new way while detecting there is a driver which supports it, but in this case, BIOS switches to the new way no matter there is a driver for it or not. And once this case happens, the power button emits the keyevent only after pressing it for 6 seconds.
To fix it, we need this driver to be loaded and emits the keyevent once it's pressed.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
