When I first had some problems with my ASUS U36JC laptop I found this thread, I think the crux of my problem now is turning off the nvidia card,

I followed all the instructions in there and when I looked at the power consumption after turning off the nvidia card I had just a little bit more than he did, a little above 10000mW. Then I read the rest of the thread and did some searching and learned about ironhide, which would let me toggle and use the nvidia card.

I installed ironhide but now my power consumption seems to have sky rocketed.

jarl@jarl-U36JC:~$ sudo /usr/local/bin/ironhide-disablecard
DOFF Disabling nVidia card succeeded.
jarl@jarl-U36JC:~$ grep rate /proc/acpi/battery/BAT0/state
present rate: 47432 mW
