Under Windows 2000 the sleep state works good (this has nothing to do with ACPI if I'm right). The standby state works also good. Now I tried to use the ACPI functions under Linux. I've installed Redhat 8.0 and compiled the latest 2.4 kernel with the latest pre-patch (2.4.21-pre4) and the latest ACPI patch(20030125). Because there isn't much documentation available about the acpi functions I experimented a bit with the files in the /proc/acpi directory. With my previous notebook I could issue the command 'apmsleep 12:00' to the notebook which would let it suspend till 12:00. Now with my notebook, I can't issue this command anymore (cause my new notebook doesn't support APM, only ACPI). Does anybody know if there is an tool/command to let the notebook suspend till an specified time ? I've seen there is a file named /proc/acpi/alarm there with an date+time in it. I tried to echo an date+time in it, but as soon as the command executed, my notebook would hang. Now I tried to install the 2.5.59 kernel with ACPI patch 20030125, but as soon as the machine booted it would hang. Now I tried the newest 2.5.59-bk2 patch and my notebook now normally boots. The hang with the /proc/acpi/alarm is now solved, but as soon as the date+time is set the notebook continues to work normally and when the time is reached the notebook would hang. The /proc/acpi/sleep same story..if I echo '4' in it the notebook would continue to work..if I echo '3' the notebook would hang...with echo '5' the notebook would also hang... Is this because the ACPI support isn't complete yet or am I doing something wrong ?
