移动性是笔记本电脑最主要的特征,如何提高它的灵活性和稳定性是笔记本电脑面对的首要问题,作为笔记本电脑的供电部分,更是保障其有效工作的关键环节。笔记本电脑的电源系统是仅次于CPU及其主板、显示屏的第三大关键部件,包括电源适配器、充电电池和电源管理系统等。考虑到散热问题,电源适配器一般独立于笔记本电脑主机之外。笔记本电脑对电源要求很高,稳定性和抗干扰性是检验电源适配器的主要指标。为了避免输入电源的纹波系数过大或突然的高电流冲击而烧毁电源适配器,应尽可能接至带有过载保护的电源插座。一旦出现停电现象,电池便体现出它的优越性了。笔记本电脑的便携性很大程度取决于电池的支持,电池是整个电源系统的心脏,所以不能轻视它。笔记本
Mobility is the most important feature of notebook computers. How to improve its flexibility and stability is the primary issue faced by notebook computers. As the power supply part of notebook computers, it is also the key link to ensure its effective work. Laptop power system is second only to the CPU and its motherboard, display the third largest key components, including the power adapter, rechargeable batteries and power management systems. Taking into account the heat problem, the power adapter is generally independent of the notebook host outside. Laptop computers on the power requirements of high stability and immunity is to test the main indicators of the power adapter. In order to avoid the input power supply ripple factor is too large or sudden high current impact and burn the power adapter should be connected to the power outlet with overload protection. Once the power outage phenomenon, the battery will show its superiority. Laptop portability depends largely on the battery support, the battery is the heart of the entire power system, so can not underestimate it. notebook
