I recently purchased a Lenovo Y510p with a 2 GB Nvidia GeForce GT 755M and Haswell i7 with an Intel HD 4600 (in built).
The laptop is amazing for gaming... the 755M is a very powerful card indeed. But when I remove the AC charge,games I try becomes super laggy.
I have tried all the workarounds... I changed the Nvidia Optimus control center settings and changed all my games default card to nvidia processor, but it doesn't make a difference.
The games I have checked this with i the following:
NFS Most Wanted (2012)
Call Of Duty Black Ops 2
Basically, all graphic intensive games... they work on Very High/ Ultra on AC power (nvidia 755m), then become super laggy or crash when the power is removed .
I contacted the nvidia technical support and they told me that generally the control panel change might do it and that I must check with the manufacturers on this.
My question is if this is a design specification that the Nvidia 755m is deactivated (is it deaactivated?) when the laptop is on battery or is this an anomaly or is this a power management system threshold issue in my laptop and I must get it checked?
Please reply soon guys (Admin)... this is really troubling me.
PS. Anyone with insight into this or facing the same issue, please comment on this forum thread.

Hi there....i am from mumbai and i also own a Y510p , ...you can do one thing ...minimise the game and from the Power Management Software> Select Performance...else the clocks of the core of cpu gpu are restricted !...
seems that the battery doesnt provide enought wattage for the graphic card when the adapter is removed ..which is an issue and lenovo should get it fixed ASAP !

Hey i have the same problem with the Y510p and the same specifications as mentioned above.
However my notebook worked fine until 3 days ago. Before that my games also did run smoothly without the AC plugged in. However now when the AC is not plugged in i get only 20fps or less. With the AC it's around 80fps. Both times the SLI is activated.
Is there a problem with my battery, that it does not give enough power or is this a driver/software problem?
I also tried this link as mentioned above:
That didn't change a thing.
Need your help guys!!

This is the case with all laptops. You´re not supposed to be able to play demanding games without being plugged in to power. The point of this kind of PC is not that you will be able to run powerfull games on your lap or in the bus, but that you can move it from one location to another in a bag or such. Think of it as a portable desktop, not a laptop gaming wonder device.

I also had the same thought linke you, however what did confuse me is, that now i can't even play low consumption games like COD4 even with SLI deactivated.
They should run smoothly with one GT 755m and an i7. However it runs only with 35fps.
There is obviously an power consumption error somewhere, and i can't believe that it is not possible to use this notebook without an AC plugged in. I would understand that it's too much to use both gt 755m but it obviously has problems to run even a singe graphic card.

Hey there, I have the same problem. I have the I5 4200M variant, non SLI. Games run fine when charger is plugged in but starts lagging as soon as the power is cut out. Also it heats up to extreme temperatures even in 15-20 mins of mediocre gaming. What the hell is this? I did not pay 55k+ for this **bleep**. Fix this Lenovo!
