On Fedora 39 a simple script can indicate with one of the side leds that the the FW 13 intel has been suspended to RAM.
Install fw-ectool first
For instructions see:
https://copr.fedorainfracloud.org/coprs/bsvh/fw-ectool/
Then, add a simple systemd script in :
usr/lib/systemd/system-sleep/
And name it e.g. leds. Make the script executable.
#!/bin/sh
## location : /usr/lib/systemd/system-sleep/leds
if [ "${1}" == "pre" ]; then
ectool led right blue
elif [ "${1}" == "post" ]; then
ectool led right auto
fi
As a result, when the laptop is in a suspended state, the right side led will show blue.
As simple as that!
Kind regards,
Otto
