Boot loader entry?

[ghost]

I am afraid that, on Mint 19 and even using the Grub Customizer program, I find nothing on my system that corresponds to a /boot/loader/entries/arch.conf or to anything much like this:

title		Arch Linux ACPI
linux		/vmlinuz-linux
initrd		/intel-ucode.img
initrd		/acpi_override
initrd		/initramfs-linux.img
options		root=/dev/nvme0n1p2 rw i915.enable_guc=3 mem_sleep_default=deep

The closest I get is this:

Sorry if I am being dim.

PS: I have returned to your script, and an earlier version of my BIOS, because the X1's 1.30 BIOS 'Linux' sleep option was causing problems with my touchpad.

OK, it seems I should put

/boot/acpi_override between the last two lines of the output that I posted. Putting it elsewhere throws an error. However, my syslog continues to report that the sleep state was 's2idle'. Perhaps the computer only goes into deep sleep after a certain period has elapsed?
