Ok Acer E5-573-38T2 Broadwell i3-5005u ubuntu 16.04.1/16.10 going freeze and black screen after suspend, fan still spins, the power light is on and the battery is trained. This problem only when plug in, on battery or when charged works fine. For me works this https://wiki.archlinux.org/index.php/Acer_Aspire_E5-573 "suspending to RAM (S3 Sleep state) and hibernating to disk don't work when running on AC power. After debugging with https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt culprit revealed to be the non-boot online cpus."
Create file: $ sudo nano /lib/systemd/system-sleep/sleepcpu put that script and save: #!/bin/bash case "$1" in pre) for c in /sys/devices/system/cpu/cpu*/online; do echo 0 >$c; done ;; post) for c in /sys/devices/system/cpu/cpu*/online; do echo 1 >$c; done ;; esac Save it, and: $ sudo chmod +x /lib/systemd/system-sleep/sleepcpu After that going to suspend perfect, but when wake up sometimes freeze. If you have this, make another script. $ sudo nano /lib/systemd/system-sleep/network Put script: !#/bin/bash case "$1" in post) sudo service network-manager restart ;; esac Save and $ sudo chmod +x /lib/systemd/system-sleep/network After that suspend on my acer work perfect, testing 20/20 all works.
