$ uname -r
4.15.0-23-generic

$ lsb_release -r
Release:    18.04

First happened after upgrading kernel version to 4.15.0-23-generic but when I switched back to 4.15.0-20-generic it worked fine until now (there was an update a few days ago). Now my laptop does not wake up from suspend on either kernel version.

Any suggestions on what to look at / try out? I've tried the suggestions I've been able to find online but to no avail.

For me, the problem was solved after updating to kernel 4.18 with ukuu Ukuu is a program that allows the easy installation and removal of newer or older kernel versions in a graphical way It is easy to use and install: makeuseof.com/tag/upgrade-kernel-ukuu-ubuntu. Of course , you can use command line or download the kernel and install I didn't have any problem with the new kernel but in case you face problems, you can uninstall it by booting from the old one, using the grub menu Hope it helps
