I have a Lenovo Thinkpad T540p with Ubuntu 18.04 and when I manually suspend the laptop & then close the lid, the laptop actually resumes. Looking through the side of the lid, I can see the screen flickering.
Running journalctl -u systemd-logind.service I can see the following:
iul 18 20:36:08 vt-thinkpad systemd-logind[966]: Lid closed.
iul 18 20:36:08 vt-thinkpad systemd-logind[966]: Lid opened.
iul 18 20:36:08 vt-thinkpad systemd-logind[966]: Lid closed.

iul 18 20:36:09 vt-thinkpad systemd-logind[966]: Lid opened.
This tells me that the hardware switch might be broken & it bounces.
I have tried the following changes:
Gnome Tweak Tools -> Don't suspend on lid close
/etc/systemd/logind.conf changed to
24 HandleLidSwitch=ignore
25 HandleLidSwitchDocked=ignore
26 #PowerKeyIgnoreInhibited=no
27 #SuspendKeyIgnoreInhibited=no
28 #HibernateKeyIgnoreInhibited=no
29 LidSwitchIgnoreInhibited=no
/etc/UPower/UPower.conf changed to:
31 #
32 # Some laptops are broken. The lid state is either inverted, or stuck
33 # on or off. We can't do much to fix these problems, but this is a way
34 # for users to make the laptop panel vanish, a state that might be used
35 # by a couple of user-space daemons. On Linux systems, see also
36 # logind.conf(5).
37 #
38 # default=false
39 IgnoreLid=true
I am a bit lost. Ideally I would find a way to debounce/ignore the repeated Open/Close cycle happening in less than 1s or so, but I am good with completely ignoring the Lid switch if possible. Because of this issue, I am unable to close the lid when suspending my laptop. I can only turn it off, which is not a viable option for me.
What can I do about this?
