Low-power consuming notebook
Hi, my brother is looking for a low power consuming notebook for studying mainly and needs help.
Well, to make things a bit shorter, we'll found the Dell Inspiron 13v and 15v to be very interesting. They're running with dualcore Intel CULV CPUs, the Pentium SU4100 (see http://en.wikipedia.org/wiki/Consumer_Ultra-Low_Voltage) with the choice of the Core 2 Duo SU7300 (1 MB more L2 cache only I think, 40€ more - needed?) and you can chose between the Intel X4500MHD and the AMD Radeon HD 4330. You can choose between a 5400RPM (default) and a 7200RPM hard drive and we want to use the big 8cell battery so it lasts over 8 hours at least.
Here are our questions:
1.) Would it be worth to spend 40€ on the faster CPU?
2.) Would it be worth to spend money on a 7200RPM hard drive?
3.) What exactly is the state of the Intel drivers for the X4500MHD? Is it the i965 mesa driver? How is 2D/Composite performance, what about watching videos?
Also, with the current state of the opensource drivers, would the AMD Radeon HD 4330 be an option (no powerplay support yet)?
4.) Is the Intel WiFi Link 5100 chip well supported by opensource drivers (Ubuntu 9.10)?
5.) Anything else that could should be mentioned? Any closed source drivers needed (we don't want that)? See: http://www1.euro.dell.com/content/pr...edhs1&ref=lthp
If you would find a system with nvidia gpu i would go for it
Cool, so the opensource nVidia drivers are in a better shape than AMD & Intel now?
Read again, as we don't want no proprietary crap like the nVidia driver on there.
Well as long as you define video with at max 720p it should not matter.
He won't play 1080p video.
But someone knows if a HD 4330 sucks (a lot?) more power than the Intel IGP with opensource drivers? Again, how do the Intel drivers perform right niw?
Hi d2kx! I have a laptop (Acer 6930) with an Intel 4500MHD and it is working fairly well, but at least for now it doesn't have h264 accel (only mpeg2 with vaapi).
About the HD 4330... OSS drivers don't do PowerPlay now, so I think it would consume more energy, but maybe you can enable/disable the Ati GPU in the bios (some laptops have this option) and use the Intel GPU when is needed.
Both GPUs are good to watch videos. If you use mplayer-mt it will work even better. For the Ati GPU there is xvba-video now with Catalyst (I know you don't want closed drivers, but is good to know that the video accel is supported), with the OSS driver XV is working ok too.
Intel WiFi 5100 is supported, I have the same chip in my laptop and is working well... I use Arch in mine, but Ubuntu installs automatically the firmware and drivers so you won't have problems with it.
I hope this helps you.

How about just an external battery pack?
