Hi List, i got my 3810TG a last week. TG is the new series with Buetooth, UMTS and ATI switchable graphics on a Radeon 4330. After installing openSuSE 11.2-Milestone6 an some initial configuration, powertop gave me over 20 watts of power consumption. As the BIOS was set to "switchable graphics", i guessed that BOTH graphic chipsets were active. lspci listed both, Xorg however, only could find the onboard Intel chipset. After switching to "discrete" in BIOS, i could install fglrx (after patching for kernel 2.6.31) and power consumption went down to 12 watts, probably due to ATIs PowerPlay.
The BIOS has _no_ option to disable the ATI chipset. Lenovos BIOS offers a third option "integrated" to deactivate ATI completely. So these long battery lifetime can ONLY be reached in Vista. I wont be satisfied with this. Has anyone of you confronted Acer with this problem? Or do you know if a better BIOS is to be realeased? I also found no piece of software to deactivate ATI via software in Linux.
