Since the update from 4.19 to 5.2.9 my Lenovo Thinkpad E460 no longer suspends properly. If I
close the lid or chose Suspend from the KDE launcher, the system will start to suspend but never
reaches standby. Power light will blink as usual, display backlight turns off but keyboard LEDs
don't turn off, fan is still active.
The system doesn't respond to Ctrl-Alt-Del or change to a Terminal. No input changes anything.
Waiting (30min) doesn't help either. Rebooting to Kernel 4.19 fixes the problem immediatly.
Expected outcome would be a complete suspend/standby state and a complete recovery/powerup on
lid open or press of any key.
