The difference between the power cord plugged into the notebook Win7 system and the direct use of the battery is not plugged in.

The role of the power adapter: is to recharge the battery when the battery is not available, or the battery is removed, you can directly power the machine, but the battery and power adapter Although the idea of the supply voltage is the same, but the actual use of people raspberry.

1, the fever is not the same

When using the battery, notebook or ultra-high-heat situation, as long as the hardware is not a problem or bad heat, generally will not be overheated, but the use of power adapter connection, but it is likely to occur overheating, this phenomenon in the summer is particularly obvious

2, the intensity of the operation is not the same

If you just use the battery and not plug the power cord, when watching high-definition movies or play large-scale games, you may be very card, which will make many people strange naming the power adapter is only for charging, and the battery is enough power, why not plug in the power adapter when it is compared to force it?

In fact, this is because the use of power adapter and separate use of the battery, the input power is different, so the hardware is not the same strength, in the case of high computer load, this speed gap will be more obvious.
