installed the leap 15 on a HP 300 mini (Pavilion Mini) desktop. The darn think refuses to suspend, gfx goes off (so the lights on the USB keyboard) but the system is still working (system fan is working and power LED is still on, not blinking). I even updated the kernel to 4.16 (stable) (bit better response, as while on 4.12 I only could ‘wake’ up the display by pressing the power button, while on the 4.16 the display can be switched on by just pressing a key on the USB keyboard)
swap is 8GB (same as RAM) , well the system suspends and resumes well using other distros like Ubuntu and Fedora (tested on live images, just to rule out a possible h/ware fault) still no idea whats going on with the opensuse, probably not compatible with that 4-5yo system
