Laptop logs out when running on battery

[crakken]

Hey guys,

I have a strange problem. Whenever I try to run my computer on battery power it will log me out after only a few minutes and I will be back at the login screen. The computer runs fine when connected to AC power. I am running 11.10 on a MSI GT660 with a i7 740 and 6GB of RAM. I have never had this problem with any other Linux distros and am kind of at a loss. I hate running my WIn 7 install, but it is the only way that I can use my laptop without plugging it in.

Let me know if you need any additional info and I will do my best to provide it.

Thank you,

SYSTEM INFO
Make: MSI
Model: GT660-003US
Processor: Intel i7-740 Quad Core
RAM: 6GB DDR3
OS: Ubuntu 11.10

Steps required to recreate problem:
All i have to do is unplug the laptop and open any program, or let it sit for a few minutes and everything will crash and I will be brought back to the login screen.
