Shutdown while logging in on battery power

Hello,

I just installed CAELinux and this is my first linux os.

The install seemed to work, but the problem is when I try to log into my account while using my battery and not a/c power. When I type in my password and hit enter the computer instantly turns off.

With the a/c plugged in there are no issues. If I have the computer plugged in while I log in then unplug once I am logged in then everything works fine.

I have done the upgrades to ubuntu 14,
Asus N53vs,
16gb ram,
samsung ssd 850 evo hard drive,
I7 processor.

Any help would be greatly appreciated.

Thank you

I did some searching and I noticed that in "power information" my computer thinks my battery has 12.5 V and on my battery it only has 10.8.

Could this be a problem?

How would I update that?

Thank you,
John

I tried doing some searching. I found that my Nvidia card (GT 540M) was conflicting with my integrated graphics card. I trying over a dozen fixes but nothing seems to work. The crashing is happening before grub can finish loading now.

I am really struggling with this transition and spend countless hours trying to google an answer.

Any help would be greatly appreciated.
