What is battery life like for you? I tried Ubuntu on an Asus laptop 4 years ago. Windows would get ~7 hours, while Ubuntu barely managed to get 3 hours.
I love using it on desktop, but it sucks (sucked) on laptop when I used it.
Try using tlp and powertop to diagnose the issue (your CPU might not be entering low power C states -- a common problem with older kernels that don't support the latest Intel CPU architectures), so also upgrade your kernel.
Linux has consistently gotten 1.5x as much runtime on battery for me as Windows.
