The documentation in Documentation/power/swsusp.txt reads:
,---- | Sleep states summary | ==================== | | There are three different interfaces you can use, /proc/acpi should | work like this: | | In a really perfect world: | echo 1 > /proc/acpi/sleep # for standby | echo 2 > /proc/acpi/sleep # for suspend to ram | echo 3 > /proc/acpi/sleep # for suspend to ram, but with more | power conservative | echo 4 > /proc/acpi/sleep # for suspend to disk | echo 5 > /proc/acpi/sleep # for shutdown unfriendly the system | | and perhaps | echo 4b > /proc/acpi/sleep # for suspend to disk via s4bios `----
I do get: root@hermes:~# echo 2 > /proc/acpi/sleep bash: /proc/acpi/sleep: No such file or directory

System is a Thinkpad R40, Debian/sarge with kernel 2.6.14-rc1. Did I miss something obvious?
