ACPI: Wakeup problem

[Szpak]

Hi,

After long battle I forced my computer to going into stanby mode under ACPI. Unfortunately I can't get out from that state
To change state I used:

cat -n "standby" > /sys/power/state

I noticed that computer doesn't respond on inputs (keyboard, mouse, etc.). In /var/log/messages I have:

szpak kernel: ACPI wakeup devices:
szpak kernel: PCI0 PS2M PS2K UAR1 USB1 USB2  LAN  MDM  AUD SLPB
szpak kernel: ACPI: (supports S0 S1 S4 S5)

but:

[root@szpak szpak]# cat /proc/acpi/wakeup
Device  Sleep state     Status
PCI0       4            disabled
PS2M       4            disabled
PS2K       4            disabled
UAR1       4            disabled
USB1       4            disabled
USB2       4            disabled
 LAN       4            disabled
 MDM       4            disabled
 AUD       4            disabled
SLPB       4            *enabled

I changed status of PS2M and PS2K to enabled using acpitool, but despite of it I still can't get out from standby. I have acpid running and ampd disabled.

Two more questions:
1. Is "sleep buton" the button on my keybord? (if yes, then it doesn't work)
2. Is S3 is missing on ACPI supports list, it means that by BIOS doesn't support it or I have to change something in my system?

Thanks for advices
Marcin

If ACPI in dmesg doesn't show you S3 then it's either not supported by the BIOS or turned off in the BIOS.

If you have an nVidea system most likely it is hard to get it awake again. You might look for a description on that in the ACPI sources of the kernel or elsewhere.

Thanks for reply.

In BIOS I haven't found any option releated with S3. W have ECS K7S5A. It has few years.

It's on SIS chipset, but I have NVidia graphic card. Suspend monitor works ok (via settings in screen server). Probably I'll have to back to APM again (I try ACPI with every new Fedora ;( ).
