    I was reading a review of an HP computer with the same processor as mine (Intel T5250 1.5ghz) and they said they ran SuperPi in 1 minute 17 seconds (to 2 million digits). I decided to run Super Pi on mine just for the hecknot of it. While other things were running and on battery my DV6565US ran 1 minute 23 seconds while I was on battery and full performance mode (at 2 million digits). I did the same test latter with the AC power and it ran 2 minutes 24 seconds at full performance mode. I repeated this several times and got same results. So, I am wondering why performance is better on battery - and insights here?



    Oh here is the review I mentioned above (it was for HP Verve dv2550se)

    "he Intel T5250 clock speed is 1.5GHz and cache is 2MB and Front Side Bus speed is 667MHz. The T7100 is 1.8GHz with 2MB of cache and 800MHz Front Side Bus speed, and the T7300 is better yet with 2.0GHz of clock speed, 4MB of cache and 800MHz FSB. I ran a popular benchmark named Super Pi on the dv2550se that you can use to force to calculate the value of Pi to a set number of digits of accuracy. The Intel T7100 processor can calculate Pi to 2 million digits of accuracy in 1-minute 9-seconds while the T5250 took 1-minute 17-seconds. This isn't a huge difference, and in every day use you won't really notice it, but it does show the T5250 is going to be slightly slower. Running PCMark05 provided a score of 3,189 which is really quite respectable."

    Well... that is sort of weird. Perhaps some other programs are scaling down due to being on battery, and as a result freeing up resources for superpi?
