My battery backup hardly lasts for 45mins. I searched for a similar problem but din't find any solution applicable to me.
I use Nvidia GeForce 525M graphics card and use Nouveau. My laptop gets heated up to about 85 deg (according to jupiter). Such a power consumption is too much for my battery.
Is there any way I can enable my graphics card and load my kernel module only when needed without restart or logout?
And till that time use only the integrated Intel graphics card.
(And I do not mean blacklisting as I would have to log out to enable it.)
I need a run-time loading and unloading of modules.
Update : I installed Bumblebee which increases the battery life to 2 hrs.(approx.) . However, I'd like to know how to load kernel modules after completing boot process.
