I confirm that adding the option

acpi_osi='!Windows 2012'
to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub at least makes the
lid close suspension behave correctly. It's been two weeks since I made
that change, I suspended and rebooted several times, and still when I
close the lid the suspension works fine.

Just to make it clear, and if you want to try it yourself, you should
open /etc/default/grub with your text editor (and with sudo privileges)
and replace the line starting with

GRUB_CMDLINE_LINUX_DEFAULT

with the following:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi='!Windows 2012'"

It would be nice to know if this solution works for other users as well.
