Yes, but the problem with ondemand is that it cannot distinguish if
your ac adapter is connected or not, and so you cannot modify its
policy as for example having always maximum speed pf the processor
when the ac adapter is connected.
You can also consider using the 'conservative' governor, that is
optimized for a battery powered environment and solves the problem of
the latency in transitions between maximum ad minimum frequency in
amd64 cpu's.
