I am having the same problem with Acer C720 running Ubuntu 18.04.4 HWE kernel 5.3. I had hybrid-sleep setup for lid close, and it was working fine with 18.04.3 HWE kernel 5.0. A few weeks ago the system updated to HWE kernel 5.3. Now it seems to go into hybrid-sleep when the lid is closed. When I open the lid the computer restarts. I have tried regular sleep and regular hibernate from the command line. They seem to work, the screen turns off, the blue led light in front goes off and turns to slowly blinking orange in case of sleep and goes totally off for hibernate. However resume does not work. The computer restarts instead. I will be happy to provide logs and config files if needed.
