I'd like the second the suggestion that s2idle sleep not be used at least on this model until the power usage issues have been worked out. It wasn't easy to figure out what the problem was and the battery drain will significantly reduce the lifespan of the laptop for users that don't know to change the setting.

I have confirmed this by suspending and then checking: sudo journalctl | grep "PM: suspend" | tail -2. If the output is PM: suspend entry (s2idle) PM: suspend exit cat /sys/power/mem_sleep showed [s2idle] deep As a temporary fix, I typed echo deep > /sys/power/mem_sleep as a root user (sudo -i). Then the output of cat /sys/power/mem_sleep was s2idle [deep] After suspending now, sudo journalctl | grep "PM: suspend" | tail -2 returns PM: suspend entry (deep) PM: suspend exit I have made this permanent by editing /etc/default/grub and replacing GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=deep" then regenerating my grub configuration (sudo grub-mkconfig -o /boot/grub/grub.cfg). This appears to be working with no ill effects.
