Public bug reported:
Recently my Lenovo ThinkPad W540 laptop has been unable to suspend
correctly. It immediately wakes up after going through all the usual
steps of turning off the screens, USB devices etc.
I'm using the UI to suspend by left-clicking and holding the power off
button until it turns into a pause button, and then I left-click that
button. The laptop is docked with two monitors connected and the lid is
open (although the laptop screen is not used) when I attempt to suspend
it.
This used to work until recently. BIOS has not been touched or upgraded.
