I bought a laptop few days ago, Lenovo Z480 with Windows 8. After some hours I could finally install dualboot windows 8 and ubuntu 12.10, one thing is that I need to change BIOS setting each time I want to change OS.
But the main issue is that my battery last no more than 1 1/2 hours or 2, and if I watch video less than 1 hour, on the other side using windows 8 the battery last until 4 or 5 hours. Installing Jupiter there's no change, my battery dies so fast.
Would be a linux kernel update in the future to fix this problem? Or I must look for a quick solution? Any ideas?
Thanks in advance, if you know what to do, please let me know =)
