Windows 7: Shorter Battery Life (futitsu laptop) - Do I need software ?

Hi,

I've been using windows 7 for about a week on my Fujitsu A-6110 laptop.
Windows 7 (7057 32bit)
Fujitsu A-6110
Core-2-du0 1.5 GHZ
2.5 GB Ram

When I had windows vista home installed I could run this laptop on "power-saver" mode for 3+ hours, when I bought it a year ago maybe 4 hrs on power-saver mode. At this setting I have the laptop on the lowest brightness level.

Now with Windows 7 installed my battery lasts about 1.5 hrs on powersaver mode with the brightness turned all the way down. Its been 45 minutes now and it is at 52%.


Is there some kind of Fujitsu battery power software I need to correct this ?

Thanks -Brian

Having the same problem anyone have a solution?
