The out-of-the-box power consumption is quite high, resulting in about 2 hours life for a full battery charge. The cause seems to be the nvidia graphics chip which, as explained earlier, I’m not using anyway because of it’s instability with Ubuntu. The best thing is to switch off the nvidia chip altogether, other smart people  figured out how to do that. I’m quoting:
Install the bumblebee ppa:
/etc/apt/sources.list.d/bumblebee-stable-raring.list should then look like this:
|deb http://ppa.launchpad.net/bumblebee/stable/ubuntu raring main
# deb-src http://ppa.launchpad.net/bumblebee/stable/ubuntu raring main
|apt-get install bbswitch-dkms|
/etc/modules and disable the NVIDIA card by default:
blacklist the nouveau driver in
Things that don’t work yet
I strongly recommend sticking with the default graphics driver and not using the nvidia one as it freezes the X-server sporadically unprovoked.
I got the nvidia chip working after all. Bumblebee seems to do a pretty good job so far and I have not noticed instabilities. For normal (unity2d) operation it uses the intel chip and for advanced graphics the nvidia chip. I’ll post more about the precise setup later.
The fn hotkey for toggling the WLAN doesn’t work. I am still looking for a workaround.
The bluetooth module seems to be pulling almost 10 watt. I’m disabling it on startup with a script:
rfkill block bluetooth
The largest hassle so far is that the battery will sporadically not charge. This seems to be a widespread problem with the NV series, a workaround is to remove the battery, shortly run the laptop, switch it off and place the battery back in.
