![]() Users found that manually switching from a power-hungry discrete GPU to the more efficient built-in Intel Core GPU could significantly improve battery life. The bug is reproducible with or without the update.GfxCardStatus 1.0 was announced on the MacRumors forums as a " public beta" in Spring 2010. August 17's Snow Leopard Graphics update changed some of the symptoms of this bug, but did not fix it or reduce it's severity. ![]() The real fix for this bug is up to Apple. However you may wish to uninstall the DisplayLink driver and turn " Automatic graphics switching" on if you are expecting to need longer battery life (such as on a long flight) and are not using graphics-heavy applications. So turning " Automatic graphics switching" off is a good workaround for almost all use-cases. This means that if you use one of these workarounds, the MBP will consume about 11% more power than it would if you uninstalled the DisplayLink driver, unplugged anything from the MBP's MDP and turn " Automatic graphics switching" on. Most of the suggested workarounds above only prevent the MBP from switching to the lightweight GPU. Most software-screens have no hardware component.) (Only the DisplayLink software-screen has a hardware component. OS X 10.6 has a bug which prevents software-screens and the lightweight GPU from working together, even when the software-screen's hardware component is physically disconnected. The USB DisplayLink device uses a " software-screen" - that means a screen which does not have hardware which the OS can interact with about directly. However, the GPU switching in itself however is not the issue. " Automatic graphics switching" is off - this disables the GPU-switching feature. ![]()
