I'm having trouble with suspending the system. After several tests and several distributions I am doubt whether the problem is in the system or if it is with my hardware.

I made an intriguing discovery today, set the BIOS as default and the SATA controller changed to IDE, I started the system to see what happened and was able to suspend and wake the system once without problem. When I returned the SATA controller to AHCI the problem in suspending the system returned to give error.

The system suspends but does not wake up, I only hear the coolers turning on but the monitor stay black. Description: Ubuntu 18.04 LTS Motherboard: GA-H67A-UD3H-B3 / BIOS Version: F8 CPU: Intel(R) Core(TM) i5-2500 CPU @ 3.30GHz display: Radeon HD 5770 disk: ATA Disk / SSD KINGSTON SVP200S (120GB)

  • Yes, but unfortunately did not wake up later, even symptom I hear the coolers on but the monitor is still black. There are a log that shows what happened? – Cesar Lopes Jul 14 '18 at 21:02

Installing laptop-mode-tools it seems that you solved the problem.

sudo apt-get install laptop-mode-tools After install use lmt-config-gui to configure it.
