简单解析笔记本内部硬件构造图

简单解析笔记本内部硬件构造图笔记本电脑作为我们日常生活中的一个重要的工作学习的工具，已经被大家所熟悉，广大电脑爱好者应该都接触过笔记本，它相比台式机体系小巧便于携带，但也正因为它的体形较小，拆卸较台式机稍显困难，所以笔记本内部的“内脏”便有一独特的种神秘感。

笔记本内部构造图（联想Y40笔记本）下面我就带领大家简单的了解一下笔记本电脑的内部的奥秘：笔记本电脑虽然外观上和台式机有着很大的差异，但是内部构造其实相差无几，都是由电脑最重要的几个部件构成的，笔记本电脑基本分为两个最主要的部分：一是笔记本电脑最直观展现给我们的器件那就是显示屏，显示屏是显示计算机的输出设备是我们跟计算交流最直接工具。

二是由一部分复杂器件组成的输出设备，这是笔记本电脑最为复杂，包含器件最多部分，其中包括软驱、硬盘、光驱、CPU、内存条、主板、电池、显卡等等。

因此虽为同一类部件，体积却比台式电脑小很多，在框架设计工艺上也更加的精细，功能也丝毫不逊色现阶段笔记本电脑采用全内置方式，硬盘、内存、电池、显卡、光驱等以接口的方式与主体相连，因此更换起来更为方便。

下面着重为大家介绍一下第二部分的关键器件：（1）Cpu中央处理器（cpu，Central Processing Unit）是一块超大规模的集成电路，是一台计算机的运算核心（core）和控制核心（Control Unit）。

主要包括运算器（alu，Arithmetic Logic Unit）和高速缓冲器（Cache）及实现它们之间联系的数据（data）、控制及状态的总线（bus）。

它与内部储存器（memory）和输入/输出i/o设备合称为电子计算机五大核心部件。

（2）主板主板又叫主机板(mainboard)、系统板(systemboard)或母板(motherboard)；它安装在机箱内，是微机最基本的也是最重要的部件之一。

主板一般为矩形电路板，上面安装了组成计算机的主要电路系统，一般有bios芯片、I/O控制芯片、键盘和面板控制开关接口、指示灯插接件、扩充插槽、主板及插卡的直流电源供电接插件等元件。

2.将支架固定到键帽位置的金属架上。
Dell大部分键盘用来固定键帽支架的金属架都是三个支撑点。
我们需要将安装好的支架卡入三个金属架中。
1）请将小支架的卡勾套入下方的金属架中。
2）再将大支架左边的卡勾挂在键帽位置左上方的金属架处。
3）将大支架右边的卡勾用力按入到键帽位置右上方的金属架处。
3.将键帽固定在支架上。

固定键帽非常简单，只需将键帽直接用力扣入到安装好的支架上。
上图左边是背景光键盘的键帽；他的键帽反面是白色的，具有透光性。
上图是F1-12等功能键的键帽。
请注意标注的卡扣部分是否磨损或者破裂，如果已经损坏，是无法固定到支架上。
对于特殊性键帽支架安装步骤和以上介绍完全相同。
金属架安装方法与上相同。
再将对应键帽用力卡入到安装好的支架上，听到几声咔咔声即可。安装好的支架将弹性自如。
对于带金属铁丝的键帽，除将支架固定好外，还需将金属铁丝固定好，再将键帽卡入到支架上。
支架2型：
支架2型的安装方法和支架1型安装方法完全相同。
在此不做详细介绍。
其他机型的键帽安装方法其实都相同，掌握以上介绍的诀窍，其实键帽安装真的很简单。
（七）无线网卡拆装

笔记本电脑电路结构

笔记本电脑电路结构Company Document number：WUUT-WUUY-WBBGB-BWYTT-1982GT1、笔记本电脑电路结构框图笔记本电脑的结构图所示，整体上分为五大部分。

（1）以CPU为核心连接了CPU的温度控制电路、CPU核心电压供给电路、CPU散热风扇控制电路。

（2）以内存控制器为核心连接了内存、显卡、CPU、I/O，起着承上启下的作用。

（3）以I/O控制器为核心分别连接了IDE（光驱和硬盘）、USB、网卡、声卡、PCI总线和扩展坞等器件的控制电路和接口电路。

（4）以LPC总线为核心分别连接了SIO（超级输入输出控制器）和SMC/KBC（系统管理控制器/键盘控制器）、FWH（固件集线器），而SIO又包括了串口、并口、红外、软驱的控制电路。

SMC/KBC 又包括了键盘和鼠标的控制电路和系统管理控制器。

（5）电源供给电路和电池充电电路。

2、笔记本电脑主板单元电路综述、下面我们就以支持迅驰的Intel的855GM芯片组的整套电路结构做一个简单的介绍。

Pentium M处理器CPU是计算机的大脑，是司令。

它管理和控制其他部件进行数据传输和处理。

Pentium M处理器是Intel专门为笔记本电脑设计的一款CPU，它以低频率、低电压和多种节能模式工作，达到了很高的节电水平和很好的性能。

它的一些特点如下：1、片内集成32KB一级缓存和1MB二级缓存；2、支持SSE2指令集；3、支持增强的SpeedStep技术，可以调整核心电压和核心频率；4、400MHz的CPU总线频率。

Pentium M引出CPU总线，也称前端总线，连接北桥芯片组。

其频率为400MHz，这其实是通过在100MHz时钟周期内采样四次实现的。

CPU总线信号使用AGTL+逻辑，这是一种信号的电器特性，它可以改善信号的质量，并降低功耗。

、IP-IV核心电压控制IMVP-IV是为CPU提供核心供电的电路，由于Pentium M核心电压可调（有32种），所以要有一个能精确调整电压的电路。

笔记本电脑维修的内部结构拆解看图认识零件

笔记本电脑的内部结构
拆解（IBM ThinkPad R40 型）
将笔记本电脑的机壳拆开后，便可看到笔记本电脑内部的显示屏、主要功能部件和电路
等部分。

图1-3 所示为典型笔记本电脑的内部结构。

从图中可以看到，笔记本电脑主要
由显
示屏、主要功能部件（包括硬盘、光驱、显卡）和电路板等构成的。

图1-4 所示为典型笔记本电脑结
构分解图（IBM ThinkPad R40 型），从图中可以了解到笔记本电脑的结构组成以及各部
件
间的位置关系。

（1）显示屏
类似玻璃材质的器件就是显示屏，它采用液晶材料制作而成，是笔记本电脑特有的显示
部件。

图1-5 所示为典型笔记本电脑显示屏的实物外形。

液晶显示屏主要由液晶屏、驱动电路和背部光源组件构成。

液晶屏主要用来显示图像；
液晶屏的背面是背部光源，用于为液晶屏照明；在液晶屏中安装有多组水平和垂直驱动电路，用以为液晶屏提供驱动信号。

图1-6 所示为典型笔记本电脑显示屏的结构。

压及信号传输。

● 供电电路
供电电路是笔记本电脑的动力源，由于主板上各部分的供电电压、电流各有不同，因此
需要供电电路将电压进行转换、稳压、滤波等一系列处理后再变为多路输出，为笔记本电脑的各部分提供工作电压。

● 接口电路
笔记本电脑在工作时，常需要连接外部设备，例如打印机、U 盘、外接鼠标、外接键盘
等，而连接这些设备通常需要与其相匹配的不同接口，方能实现笔记本电脑与这些设备之间的信号传输。
