Public bug reported: Steps to reproduce: On a Thinkpad X1 Carbon running 18.04 bionic Attempt to suspend (using the the 'manual suspend' option from Gnome settings, hold down 'power' until changes to 'pause' symbol')
Expected behaviour: machine goes into suspend state, display off, fans off, power led blinking slowing to indicate can be woken only by pressing power button Actual behaviour: - display goes off - fans shut down - physical power button led starts to flash slowing - i.e. machine otherwise appears to go into normal 'suspend' state - however, after approximate 1 second, without touching anything: - the display wakes back up at the lock screen - power led comes back on full - machine is back out of suspend, without touching keys or mouse Other notes: - would appear to be 18.04 specific, as works find under 18.10 - Lenovo bios version 1.35 Possibly similiar to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1797364 but they report removing TLP solves problem (my machine does not have TLP installed) and they report dmesg errors that I do not see.
