Normalmente este comportamento so consegue ser obtido com IGP ATI + Grafica ATI ou IGP Nvidia + Grafica Nvidia.
Neste caso temos switch entre IGP Intel + Grafica ATI. Não tem a vantagem de fazer crossfire ou SLI com o ***** e a grafica mas é um passo de gigante para permitir ter um laptop que dê para jogar e ao mesmo tempo muita bateria, porque os portateis que suportem Core2 com IGP ATI/Nvidia + Grafica ATI/Nvidia são zero.
A unica alternativa eram/são os AMD Puma que têm semelhante comportamento + crossfire entre o IGP e a grafica, mas têm a desvantagem de ter um CPU mais fraco que os Core2.
Agora é possivel ter um portatil Core2 + switchable graphics (so switch. Não existe hybrid SLI/Crossfire).

One unique aspect of the T500 is its ability to be able to switch between dedicated and integrated graphics with a simple click of an icon on the task bar. You can switch between the Intel X4500 graphics and the ATI 3650 chipset without rebooting, and doing so lets you conserve quite a bit of power if you don't need to game.

http://www.notebookreview.com/default.asp?newsID=4565Unlike the T400 which saw a massive jump in battery life over the previous generation 14" notebook as a result of the LED-backlit screen, the T500's battery life was in line with the 15.4" T61. While the 9-cell battery in the T400 gave 7-8 hours of battery life, the same capacity in the T500 barely manages six hours. The key differences between each notebook are the screen size, backlit technology, and graphics card model, as all of the other options are identical.
In dedicated graphics mode, the screen brightness set to 60%, and wireless active the T500 managed 5 hours and 6 minutes before it shut itself down at 5% remaining. Even though it is still way under the T400 by a couple of hours, it is still very impressive for a 15" notebook. In integrated grahics mode with the same settings, the system squeezes out an hour and a half more, bringing the average consumption from about 13 watts down to 11 watts. The 9-cell battery gives you more than enough time to watch a movie or two on a flight, or even get some work done.

http://www.notebookreview.com/default.asp?newsID=4569I don't think I have ever used the word "insane" to describe battery life before and there is no doubt that the 14" T400 falls into that category. To get 10 hours of battery life from a notebook this size, most people think you would need a huge battery attached to the bottom of the case, another battery taking the place of the optical drive, and a big battery sticking out the back. With the T400 you can reach 9 hours and 41 minutes with the wireless enabled, screen backlight at 60%, and the laptop in integrated graphics mode using only the 84Wh 9-cell battery. In this situation the notebook is only consuming roughly 8.5 watts of power. In dedicated graphics mode under the same settings battery life falls by exactly 2 hours down to 7 hours and 41 minutes, and power draw increases to 10.5 watts. The 6-cell battery managed 6 hours and 4 hours and 28 minutes respectively.
