Today, I tested rtcwake on several x86 or x86-64 based computers.
The outcome:
(1) Suspend to RAM (say, "rtcwake -m mem -s 10"):
* Success: Every system.
(2) Wake-on-timer ("rtcwake -m no -s 120 && shutdown -h now" or "rtcwake
-m off -s 120"):
* Success: Lenovo Thinkpad X220 (2012?), and a 5-y
Reminds me of the nvram-wakeup lotto back in the day.
