If I do a echo -n "standby" >state, then it appears to suspend for 1-3 seconds, power light blinking, etc. Then comes back to life. I cannot figure out what is waking it up. acpitool say all wakeup devices are disabled. # acpitool -w Device Sleep state Status --------------------------------------- 1. PCI0 1 disabled 2.
