yes,laptops with vista os does consume more power than those xp ones,my newly dell laptop ofcourse with vista home basic os when fully charged battery will only enable me for 2hours 15mins + before the battery totaly gone.
Today I had the most awful mobility experience with my laptop, EVAR. I don't really take my big 17" screen laptop out much, so I admit I never actually had much occasion to test how well Vista performs on the road. Well, today my wife and I took a trip down to Stanford and I really have to share exactly what my Vista Mobility user experience was.
First, just to remind everyone, I have a pretty beefy laptop. Core Duo 1.73Ghz + 1.5GB RAM + NVidia GeForce Go 7600. Nothing to brag about, but this is well above what is required for Vista.
Ok, so I was about to go, so I close the lid. At that time, I had Visual Studio open, a few notepads, MSDN, and a few IE7 windows. I frowned as I watched the HD light crank for 5 minutes before I heard everything click off into sleep mode. Nice! 5 minutes is only 500% worse than XP, so tales of Vista being 1000% worse are greatly exaggerated.
A few hours later, I arrive at Stanford Tressider Union and grab a table. I pop open the lid. For about 3 minutes, the hard drive grinds again until I finally see the video initialize and the mouse pointer appear. Still a black screen tho. Another minute passes with the HD still grinding. Finally, I see my login icon and click it. HD still grinding, my desktop appears.
I glance over at the battery and it's at 88%. Ok, so Vista just used up 12% of my battery just figuring out what to do with closing and opening the lid. Isn't 88% still a B+? That's a whole lot better than I did in college, lemme tell you. Nonetheless, I immediately switched my power mode to "Power Saver" and switched off Wifi and Bluetooth using the DV9000T's hardware wireless switch. Vista complied and a little red X appeared in my networking icons, as well as the expected device unplug sounds.
Ok, so maybe I can get 2.5 hours if I'm lucky, right? Under XP, I used to get about 3 hours since I have the high capacity battery.
1.5 hours later, I'm down to 6% and Vista kicks me out to hibernate. What was I doing? Well, I was mostly coding, which means 90% of my time was spent scrolling around VS2005 and doing an occasional compile. No games. I even turned off Desktop Composition and shut down the sidebar.
1.5 hours, folks.
You know, I told people I would deinstall Vista and reimage to XP again. But, now I have this sadistic, masochistic need to see how much more awful this can get.
