Identify wakeup source?

Is there any way to identify the source of wakeup event?

I would like to know what device caused powering on (or resuming from suspend) my machine (such as power button, Wake On Lan, keyboard, usb, lid etc...). Reportedly it is possible under Windows with powercfg /lastwake command, I'm curious if this is also possible under Linux, anyone know? I've looked and googled it but couldn't find clear answer.

Install "powertop" .

Or powertop-git from AUR.
