On Arch Linux on Dell Latitude 7480 (Intel i5 7th Gen) the suspension features works when i close the computer, and it wakes up when i reopen it.
While on Ubuntu LTS / Debian Stable everything worked as normal, but on Arch when the computer is suspended the display’s backlight is on and there’s a probability that the CPU isn’t in an idle mode beacuse the fans remain pretty loud. This obvioulsy drains the battery, making imossible to really suspend the computer.
Any help?
How did you suspend the system?
By the closing the laptop lid.
does
systemctl suspendwork?i will try that, but ‘pm-suspend’ works
