Edit: After half day, my wife’s Mac started having the same problem. I have then applied the solution that I found in the Apple
A recent development in the MacBook Pro model of apple is its battery life which has been declared as much better by its predecessors from which casual users may not bother about discovering other ways to preserve energy. Having a jam packed schedule of work with an addition of some travelling issues, battery requirements is a must for a MacBook Pro model.
However, if there are schedules which will keep you away from power for a longer time period or the indicator of the battery shown signs of double digit percentages, the conservation of battery is the top thought of a MacBook user. Under such circumstances, the user can take advantage of the ability of the system to switch among the discrete as well as integrated graphics processing units (GPU’s). speaking more specifically, the MacBook user can use the free gfxCardStatus 2.1 of Cody Krieger for the purpose of forcing the laptop to make use of its battery-sipping integrated graphics processing units.
A quick sneak peak at the background of MacBook Pro: it is available in 15 inch and 17 inch MacBook Pro versions from the year 2010 and later along with the models of 2009 and 2008 which were outfitted with Nvidia Geforce 9400M/9600M GT, which has the ability to dynamically switch between a more powerful and improved performance in discrete AMD and Nvidia and a lower performed and low powered integrated Intel graphics which are mostly based on the requirements of the running programs. There is one problem, many applications that user considers does not use great amount of graphics power are actually based on the features of Core Animation of Core X’s which has the requirement of discrete graphics card. The result of this is that if your requirements for battery is huge and also wants to make the usage of battery to its minimum level by lowering down the brightness of the screen as an example, the user might still be in use of the discrete graphics card cycles which means more usage of energy.
There is a single way to ensure that the user is making use of the integrated GPU is to close off the applications which are mainly based of the discrete GPU, as the Mac operating system does not allows the user to choose the latter. The option of Energy Saver located in the System Preferences allows the user to deactivate the option of Automatic Graphics Switching. It should also be noted here that performing such an action will actually force the operating system to operate via the discrete GPU which is the way through which the battery is drained faster than before.
Now the problem is what is the solution to the issue? The answer is gfxCardStatus 2.1 which operates on the system wide menu. The icon of the menu reveals which graphic processing unit is being used: ‘I’ stands for integrated and ‘d’ for discrete. Moreover, the gfxCardStatus can be configured accordingly so as to display a notification of Growl at every that time when the GPU is changed.
When you keep an eye on these changes, you can determine which task caused the MacBook Pro to use a high powered GPU. Among all, the most essential feature of gfxCardStatus is the menu list displays which specific operating applications are dependencies or whether they are using the discrete graphics. Both can be quitted at a time top generate from the battery.
If the MacBook Pro user is worried about the battery life, the gfxCardStatus allows the facility to select among the choices of Integrated Only or Discrete Only from the utility’s menu. The Integrated Only option forces the applications to make use of limited power resources as if those applications were running on the MacBook Pro relying only on integrated GPU options, whereas , the latter one is a shortcut for deactivating the settings of the graphic processing unit.
The battery gets consumed only from using the option of integrated graphics depending on the applications you use. But, it has been experienced by switching off the dependent applications when you are working off from the power of the battery saves about 20 percent of the battery power. Moreover, you will also enjoy the scene of increased battery charge when the MacBook Pro gets itself settled into the integrated graphics mode.
