rtcwake not working

rtcwake not working:

Hi guys, when I try and run

sudo rtcwake -m disk -s 60 

all I get back is

rtcwake: assuming RTC uses UTC

rtcwake: /dev/rtc0: unable to find device: No such file or directory

If I run “which rtcwake”, I get

/usr/sbin/rtcwake 

If I run “whereis rtcwake”, I get

rtcwake: /usr/sbin/rtcwake /usr/share/man/man8/rtcwake.8.gz 

What’s the deal? I’m using 16.04 on an old HP laptop (G62).
