[Message part 1 (text/plain, inline)]

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.

Regards,
Nikolay
