On my Dell Vostro 3450 with i5 2410M Ubuntu can work over 4 hours without any power supply. I just had to force ASPM to work and put "echo powersave > /sys/module/pcie_aspm/parameters/policy" in /etc/rc.local. I know it's an awful hack, but it works. Something should be done about it. Battery lifetime should be maximized out of the box.
