With BIOS version A09 and 3.5.0-44 on 201206-11418, system will wake itself up
after it's suspended, the power LED will blink for 1 or 2 second then it will
be resumed automatically.
Although there is no display afterward, but the system still accessible via SSH.
sudo dmidecode -s bios-version
BTW, the system will enter the low graphic mode if you reboot the system after
this.
Reboot again could solve this low graphic mode issue.
