Hi, Thank you for answer about hibernation. Can you help me with similar issue with sleeping? I can freeze system and wake it up with "echo freeze > /sys/power/state" command, but system can't wake up from suspend to mem (that can be started with closing display, pressing sleep button or with "echo mem > /sys/power/state" command). Log after freeze command attached. As far as I can see wakeup must be possible with "sleep" button: $ cat /proc/acpi/wakeup Device S-state Status Sysfs node HDEF S4 *disabled pci:0000:00:1b.0 USB1 S4 *enabled pci:0000:00:1d.0 USB2 S4 *enabled pci:0000:00:1d.1 USB3 S4 *enabled pci:0000:00:1d.2 EHC1 S4 *enabled pci:0000:00:1d.7 USB4 S4 *enabled pci:0000:00:1a.0 USB5 S4 *enabled pci:0000:00:1a.1 USB6 S4 *enabled pci:0000:00:1a.2 EHC2 S4 *enabled pci:0000:00:1a.7 SLT1 S4 *disabled SLT2 S4 *disabled SLT3 S4 *disabled SLT6 S4 *disabled LANC S3 *disabled LANR S3 *disabled SLPB S3 *enabled platform:PNP0C0E:00 LID S3 *enabled platform:PNP0C0D:00 When I power off notebook and restart it after sleep there is nothing about sleep in logs.
