similar thing happens with my lenovo thinkpad x1 carbon gen5. the time
it takes for suspend is excrutiationgly long. it used to be a couple of
seconds, at most, now the wait for the red led on top of "i" in ThinkPad
logo seems to be taking for ages to start blinking. the output of the
loop (suggested by @arighi above)
while true ; do echo $(date) $(cat /proc/acpi/button/lid/LID/state) ;
done
gives the following:
