Hello,
On my both Linux (debian) systems it is not possible for me get the wake up on alarm working. I tried a lot of settings in the Bios and followed the instructions on this page: http://www.mythtv.org/wiki/ACPI_Wakeup
MoBo: Gigabyte H110M-S2H-CF
Software: Linux (debian)
According to Gigabyte I should bring the machine in state S5. What I tried but not helped:
- shutdown -h now
- shutdown -P now
EXTRA info: I find out that if I select a time in the bios and shutdown (shutdown -h now) the system started just fine from the alarm time. The problem seems to be that it is not possible to write the bios alarm with a new time.
Simple test to wake the machine 5 minutes from now should be like (but is not working for me):
sudo bash -c "echo 0 > /sys/class/rtc/rtc0/wakealarm"
sudo bash -c "echo `date '+%s' -d '+ 5 minutes'` > /sys/class/rtc/rtc0/wakealarm"
cat /sys/class/rtc/rtc0/wakealarm
sudo shutdown -h now
