---------- Forwarded Message ---------- Subject: [2.6.12-rc1][ACPI][suspend] /proc/acpi/sleep vs /sys/power/state issue - 'standby' on a laptop Date: March 28, 2005 02:53 From: Shawn Starr <shawn.starr at rogers d0t com> To: Pavel Machek <pavel at suse d0t cz>, Len Brown <len d0t brown at intel d0t com> Hello, I've noticed something strange with issuing 'standby' to the system: when echoing "standby" to /sys/power/state, nothing happens, not even a log or system activity to attempt standby mode. However, trying echo "1" to /proc/acpi/sleep the system attempts to (standby) and aborts: [4295945.236000] PM: Preparing system for suspend [4295946.270000] Stopping tasks: ============================================================================= [4295946.370000] Restarting tasks... done We get no reason as to why it quickly aborts. [4294672.065000] ACPI: CPU0 (power states: C1[C1] C2[C2] C3[C3]) [4294676.827000] ACPI: (supports S0 S3 S4 S5) What is '1' in /proc/acpi/sleep? standby mode is not the same as suspend to ram? when I put a normal desktop in standby mode its still 'on' but the hard disk is put to sleep and the system runs in a lower power mode.
