Fails to resume from s2idle on Elitebook 845 G8

Brief summary of the problem:

When I suspend my HP Elitebook 845 G8 (using s2idle, HP does not offer S3 sleep), either it does not really go to sleep but wakes up again immediately, or if it successfully suspends, it fails to resume correctly: when I press a key, the fan starts making noise, the keyboard backlight lights up, but the screen remains blank. I cannot ssh into the machine and I have to do a hard reset .
