then your laptop should realize you're doing nothing and keep the CPU
in idle state anyway. you shouldn't need to tell it specifically,
especially for such a short time. shouldn't be worth it.
sane laptops will switch off the light when the lid is closed without
software intervention.
for longer periods, like a whole night, or going outside somewhere i
obviously regularly put my laptop to standby. and indeed echo mem to
/sys/power/state is enough for this.
the problem is that this requires special software support in all
kinds of drivers, which indicates that the hardware got designed in a
silly way. but commonly you either have to use some stupid
"workaround" in the driver or you are left with completely ignoring
the existence of this "standby" feature.
