I have a Dell Inspiron N5010 laptop which has both a discrete GPU (ATI Mobility Radeon HD 5650) and an integrated GP (Intel HD Graphics). A few days ago I started to get BSOD with the atikmpag.sys 0x00000116 error. In the device manager I had stopped the ATI driver and now I can use my laptop. In the display properties I read that now it uses the VgaSave driver.
My question is: is this driver runs in the integrated GP, or in the discrete GPU? Is there any way to tell?
UPDATE: This is from the Dell Inspiron N5010 Setup Guide:
UPDATE 2: This is what Adapter Properties Window shows:
UPDATE 3: I am now really confused. I have been running my laptop for about 5 hours on the VgaSave driver, with ATI driver stopped in the Device Manager. As Fleet Command has suggested, I assumed that the VgaSave driver was running on the inegrated GP. Could you please see the attached picture and tell me why the discrete GPU heats up?
I also downloaded the latest version of the OpenHardwareMonitor, as suggested in the answer for this question (Which of the ATI Dynamic Switchable Graphics are used when there is no "switching" utility?), and its readings do not seem to be reliable as to whether the discrete GPU is engaged or not. That makes the accepted answer invalid.
Also, my system is different from the system in the question because I do not have the integrated GP listed in the Device Manager. So - different system and no valid answer = not a duplicate.
I made some more screenshots, hope that may help. I can not post images, so I can only provide the links.

The laptop CPU is Intel Core i5 M480 2.67 GHz
Thanks for the help, guys.
