On the grub menu, highlight the entry you want to boot and hit E to view the content. Make sure it has the acpi_override snippet in the initrd line.

Also, for Debian derivatives, like Ubuntu & Pop OS, refer to my post in page 11 to get the /boot/acpi_override added automatically to your initrd after every kernel upgrade.

I set the timeout style explicitly to menu, and the timeout to -1 (i.e. infinity) and still no grub menu. This is some weird stuff. I think I will remove pop_os and go with a either fedora or ubuntu.

Installed ubunti18.04 and everything works. Managed the DSDT patching, editing grub, grub menu showing, sleeping, all if it.
Dunno **bleep** pop_os had done to keep grub hidden and make all my grub changes ignored, but I can just use the theme with ubuntu anyway. Now I really like this laptop. Did the lenovo_fix for the throttling too. All good.
Thanks all for the help.

After applying the DSDT patch (running Fedora 28) I am experiencing problems from now and on with the touchpad/trackpad. They become completely unresponsive. Rebooting does not solve it. To get them working again I need to power cycle the laptop...
