The AC Power Adapter Type Cannot Be Determined, Please Connect A Dell 90W AC Adapter

Last night I upgraded the BIOS on my Dell Studio XPS 13 from A11 to A14. The BIOS upgrade appeared to work without issue however when the computer rebooted with the new BIOS version I received a boot error and then once I skipped the error I received a popup message within Windows 7 as well. The problem ended up being something really silly which is explained below but I wanted to note in case someone else ran into the same issue.

Adjust Hybrid SLI Settings Under Power Options on Windows 7

I was working on my new laptop and have been having some crashes. After analyzing some of the dump files I determined that I was having some video driver issues. When I first got the laptop I remember setting the hybrid sli mode to high performance.  After deciding I should probably switch this setting back to the default mode I was not able to find the option to switch it back. I couldn’t remember how I set it in the first place so I did a little googling and it told me there should be a GPU section under the advanced section of power settings.
