notebook Overview: HP CQ43, the CPU is i3 2330m integrated display HD3000, and the unique display is AMD 6470m
There are four ways to shield independent display:
1. Blow down the single display chip directly with the hot air blower. However, it may cause failure to start self-test. Not considered temporarily.
2. Do not install independent display drive 。 Some people say that the laptop will be fully powered, but it is not driven and cannot be used.
3. Install the unique driver and disable it in the Device Manager. Some people say that after disabling, there will be a small amount of power supply, but it will save more power than method 2.
4. Install the unique display driver, but set it in the power management of the operating system, and do not use the unique display. Some people say that this method is no different from method 3.
The problem is:
The second, third, fourth and third methods, which one is the most power saving???
This question has been puzzling me for a long time. Please ask experts and experts to answer it. thank you very much!
