The problem is I can't seem to get normal standby (S1) working. When I echo "1" into /proc/acpi/sleep or "standby" into /sys/power/state, the screen blanks for a second but comes right back (and yes, I tried delaying it with a sleep, and using echo -n). The dmesg shows: PM: Preparing system for suspend Stopping tasks: ================| Restarting tasks... done Same thing happens under X and with a very minimal kernel from the console. In possibly related news, I noticed this abnormality: # cat /sys/power/state standby mem disk # cat /proc/acpi/sleep S0 S3 S4 S4bios S5 Notice that proc does not even list S1! I was able to get suspend to disk kind of working, so not *everything* is broken :) I'd be happy to provide more info about my system, etc, but I'd even appreciate some pointers as per how I can debug this... I've done a bit of kernel development in the past, but nothing related to pm/acpi, so I'm kind of clueless here. For example, I compiled a kernel with acpi debug info, but that did not seem to give me any more messages. Is there something special I need to do to actually change the debug level? Oh a couple more questions while I am here: 1. Sometimes my system goes into a state where even holding the power button down for a while does not turn it off - I have to pop out the battery to reboot it (my broken wireless driver sometimes causes this, and so does trying to suspend to ram). Is this also an ACPI problem, or should this be handled entirely in hardware? 2. What does S4bios mean? I am assuming it somehow has the BIOS restore the RAM image rather than having to boot up the kernel to do it, so it's faster? How can I actually use this mode? Are there any docs anywhere?
