Gnome suspend issues

I’ve recently installed eos-gnome on my Lenovo Miix 710, basically a Surface knock-off from 7 or so years ago. It’s a touchscreen, and I use it with a bluetooth keyboard. I’m having an issue where it won’t stay suspended. That is, if it suspends from being inactive, me hitting the power button, using the gnome power menu, or typing systemctl suspend, it’ll go dark, but then the screen lights up again every 5 min or so, and the battery seems to draw down at about the same rate as if I were actively using it.

I’ve looked at past posts here (and many other places), and I’ve checked/fiddled with settings in /etc/systemd/sleep.conf, but to no avail. I’m pretty sure it’s a software issue, as I had debian gnome on it before and didn’t have this problem (though I had numerous others that eos has fixed). Thanks.
