This did not happen before in Ubuntu 19.04. It seems that the Dell 9360 is set to go into s2idle mode rather than deep sleep, forgoing significant power savings. I have confirmed this by suspending and then checking: sudo journalctl | grep "PM: suspend" | tail -2. If the output is PM: suspend entry (s2idle) PM: suspend exit cat /sys/power/mem_sleep showed [s2idle] deep As a temporary fix, I typed echo deep > /sys/power/mem_sleep as a root user (sudo -i). Then the output of cat /sys/power/mem_sleep was s2idle [deep] After suspending now, sudo journalctl | grep "PM: suspend" | tail -2 returns PM: suspend entry (deep) PM: suspend exit I have made this permanent by editing /etc/default/grub and replacing GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=deep" then regenerating my grub configuration (sudo update-grub). --- ProblemType: Bug AlsaVersion: Advanced Linux Sound Architecture Driver Version k5.4.0-9-generic.
