I have a Lenovo ideapad Z370 and I'm facing some problems.
- It consumes way more battery than it should, I got about 5 hours using Windows 7 and about 2 hours using ubuntu;
- If I try to install bumblebee in order to disable Nvidia VGA controller it's useful since it stills turned on;
- I've changed some grub configs and add some script that I found online to solve some of the power related issues but It's worse, after that when I unplug my laptop from power, it starts disabling my USB ports (not using any usb device that needs much power).
- Volume hotkeys are not working properly, once you try to use them, unity fails at some points and you're unable to even shutdown your system.
