you can also install powertop. It tells you what you can do to save power,
including spinning down the drives faster. I always keep my laptop on
coasters, so there is airflow beneath it, and MAKE SURE you have the vent
area clear, where tha fans blow out the hot air. I sometimes forget, and put
papers and large objects too close, and block the vents.. a sure way to heat
up your laptop in a hurry!
