arch linux macbook pro wake from suspend

When I do a pm-suspend everything seems to suspend fine.

Recently I have gotten suspend-to-ram working with pm-utils, but now it will not wake. At some point there must have been an update that broke things since then I have either been unable to suspend, or unable to wake from suspend. pm-suspend used to work fine I recently upgraded most of my hardware, and even then it worked fine. To easily provide the correct number of seconds, combine the date command with the rtcwake command.Alright, I've been messing with this off and on for the past few months. This switch wants a number of seconds since the Unix epoch (00:00:00 UTC on January 1, 1970). The -t option allows you to wake your computer up at a specific time. For example, -s 60 wakes your computer up in 60 seconds, while -s 3600 wakes your computer up in an hour. The -s option takes a number of seconds in the future. After that, can put it to sleep manually at 11pm or 1am – either way, it will wake up at 6am. For example, you could tell your computer to wake up at 6am.

no – Don’t suspend the computer immediately, just set the wakeup time.

rtcwake’s man page notes that restoring from “off” isn’t officially supported by the ACPI specification, but this works with many computers anyway.

off – Turn the computer off completely.

The computer will turn on and its state will be restored when the timer completes. The contents of your memory are written to disk and your computer is powered off. The contents of your memory are preserved. This offers significant power savings – everything is put into a low-power state, except your RAM. This is the default mode if you omit the -m switch.

standby – Standby offers little power savings, but restoring to a running system is very quick.

The -m switch accepts the following types of suspend:
