Normally, I can wake up my desktop computer from suspend by simply tapping the power button, and then after one or two seconds I'm back at the Light DM login screen. This method for waking up my system worked very well for several months, but then starting this morning, whenever I hit the power button, the system does a complete reboot, and it is no longer waking up as it before.
The only new thing I've done to my system is that I've installed a new uninterruptible power supply (due to all of the heated related power failures in my area), so I'm wondering if it is possible that my new UPS is somehow interfering with the normal wake from suspend process, or is it likely something else?
