New Lenovo - Y500

Hi folks!

I have recently bought a new laptop!

It is a Lenovo, and it is running these specs:
Intel Core i7-3630QM 2,40GHz quadcore
RAM: 8GB DDR3
64-bit OS
GT650M SLI

(this is all about when running PC games)

Whenever I have my laptop plugged into the charger, it runs extremely fast. (battery set on high performance)

Whenever I have my laptop working without the charger plugged in, it runs SLIGHTLY laggy.. I HATE it. (battery STILL set on high performance)

Why is this?! Why do I lag without the charger in?!?! Is it because I cannot run both of my graphics cards without the charger in?

I have figured out that I need to choose my GT650 SLI as primary solution here

But this is how my menu looks...

I don't have that option!!!

Thanks in advance for all answers, suggestions and help!

    the Lenovo's are designed that way and most other laptops are also. I have a y580 with a gtx660m and I have the same issue. I think this is to avoid drawing to much power from the battery as it can damage it or something.

    There is nothing "Wrong" with your laptop.

    I realise there's nothing wrong with it - but I want it to screw the battery life, and screw the integrated gpu, I want it to only use my dedicated SLI GT650M's - do you know how to do this?
  3. Wait, I see it now. Thanks a ton!

    So my laptop would basically crash, if the two dedicated graphics cards were running on full power, without an outlet.. Thanks my friend!! I love you! I now can live with it. :-D
