I know this has been a bone of contention for users of all sorts of distros for years, but I can't remember having hit it before myself.
I've been running Bionic64 with rockedge's realtime kernel happily for a few years on an ancient Dell laptop, and it would suspend (s1) perfectly when I closed the lid.
I've just swung over to a nice 2014 ThinkPad (i7+12GB) and now I can't suspend at all.
If I shut the lid, it's just shut & the machine is still running.
If I try acpitool -s then it tries to sleep but *instantly* awakens again.
(I also see that none of the ctrl-Fn keys work for (eg) dimming the display, also unlike the old Dell)
So is this something I can sort out with a bit of Puppy (re)configuration or do we think this is just bad luck & I'm stuck with it?
Can't find anything in the BIOS settings by the way relating to ACPI or whatever.
