For some weeks my MacBook 6.2 does not switch to the integrated graphics adapter (Intel HD). This is especially crucial when I work on battery (which happens quite often). I guess the runtime could be enhanced when it would take the HD adapter for display.

I checked that it automatically changes the graphics mode. I am running Snow Leopard 10.6.8.

I recently installed 8GiB RAM (not from Apple). Could this probably related to this issue? Actually I do not want to downgrade or use the expensive Apple RAM.

So, how can I manually turn on the internal graphics adapter?

gfxCardStatus will let you choose which Graphic Card to use. It has three modes:

  • Dynamic Switching: An alias for the built-in automatic graphics switching feature in OS X.
  • Integrated Only: Forces the more battery-friendly graphics on and disallows automatic switching.
  • Discrete Only: Forces the more power-hungry graphics on and disallows automatic switching.

Seems quite nice, but sadly I can't use it due to Snow-Leopard 10.6.8. But I found in the source code, where the line probably has to be changed. I'll give it a try. –  mistapink Mar 1 '13 at 9:02
    
gfxCardStatus v1.7 (v2.3 now) did work for Snow Leopard. Perhaps downloading the code from gitHub and rolling back to that version might do the trick. –  Thecafremo Mar 1 '13 at 9:15
