I can definitely run for 1-2 hours even using nVidia graphics on battery, for the 1-out-of-a-million situations where I am actually on battery. So battery lifetime is never an issue for me, and therefore never a consideration in terms of whether I wish to use low-power-consuming Intel graphics or high-power-consuming nVidia graphics. Or, if I am on battery it's for maybe 1-2 hours tops before being able to plug in again. It seems that no matter what I tried, it still was up to the firmware to decide whether nVidia was needed or not.īottom line: for me, I do NOT RUN OPTIMUS AT ALL!!! I have no interest in ever using the Intel graphics ever, as I operate 99.9999% plugged into A/C power and do not operate on battery. In theory, you can configure things through nVidia Control Panel so that particular programs of your choosing will FORCE use of the nVidia graphics on the laptop screen, but my experience is that I've never had the expected success trying to get this to work. If you use an external display (connected to the miniDP connector on the W530) the nVidia will always be used for that external display.īut in Optimus mode the laptop screen will normally always be handled by the Intel graphics, unless "special performance requirements" of particular apps justify the firmware to activate the nVidia graphics.

Optimus mode (activated in the BIOS) involves BOTH the Intel HD graphics as well as the nVidia graphics. So it would be much appreciated if someone could explain this to me :) The laptop works perfectly fine, but I would of course like to use the best display adapter, if it´s possible.
