I like to run rtcwake to wake up my machine automatically from suspend after some time using this command
$ sudo rtcwake -u -s 60 -m mem
But I get the following error:
rtcwake: /dev/rtc0: unable to find device: No such file or directory
Is there a way to fix this issue or are there any alternatives to using rtcwake?
I have a Thinkpad X1 Carbon Gen 7 machine.
