计算机硬件维修手册电脑出现的故障原因扑朔迷离,让人难以捉摸。
并且由于Windows操作系统的组件相对复杂,电脑一旦出现故障,对于普通用户来说,想要准确地找出其故障的原因几乎是不可能的。
那么是否是说我们如果遇到电脑故障的时候,就完全束手无策了呢?其实并非如此,使电脑产生故障的原因虽然有很多,但是,只要我们细心观察,认真总结,我们还是可以掌握一些电脑故障的规律和处理办法的。
在本期的小册子中,我们就将一些最为常见也是最为典型的电脑故障的诊断、维护方法展示给你,通过它,你就会发现——解决电脑故障方法就在你的身边,简单,但有效!电脑是由各种配件组合而成的,下面,我们就根据组成电脑的各个部件分别对其经常出现的故障进行分析。
计算机硬件维修手册(主板篇)主板是整个电脑的关键部件,在电脑起着至关重要的作用。
如果主板产生故障将会影响到整个PC机系统的工作。
下面,我们就一起来看看主板在使用过程中最常见的故障有哪些。
常见故障一:开机无显示电脑开机无显示,首先我们要检查的就是是BIOS。
主板的BIOS中储存着重要的硬件数据,同时BIOS也是主板中比较脆弱的部分,极易受到破坏,一旦受损就会导致系统无法运行,出现此类故障一般是因为主板BIOS被CIH病毒破坏造成(当然也不排除主板本身故障导致系统无法运行。
)。
一般BIOS被病毒破坏后硬盘里的数据将全部丢失,所以我们可以通过检测硬盘数据是否完好来判断BIOS是否被破坏,如果硬盘数据完好无损,那么还有三种原因会造成开机无显示的现象:1. 因为主板扩展槽或扩展卡有问题,导致插上诸如声卡等扩展卡后主板没有响应而无显示。
2. 免跳线主板在CMOS里设置的CPU频率不对,也可能会引发不显示故障,对此,只要清除CMOS即可予以解决。
清除CMOS的跳线一般在主板的锂电池附近,其默认位置一般为1、2短路,只要将其改跳为2、3短路几秒种即可解决问题,对于以前的老主板如若用户找不到该跳线,只要将电池取下,待开机显示进入CMOS设置后再关机,将电池上上去亦达到CMOS 放电之目的。
东芝笔记本故障怎么维修推荐文章笔记本怎么提高性能热度:笔记本怎么解除WiFi密码热度:惠普笔记本无线网卡驱动异常怎么办热度:惠普笔记本怎么样热度:笔记本电脑键盘灯在哪里怎么打开热度:在我们面对着一年春夏秋冬的四个季节里面,由于我们的东芝笔记本需要适应各个气候所造成的影响,所以在每个季节当中,我们都需要对我们的东芝笔记本进行适当的维修与检测。
这样,东芝笔记本的散热器才能适应环境得以更长久健康地运行,然后我们东芝笔记本的寿命才能更长。
希望大家能从店铺给大家推荐的文章当中,确确实实能学到修复东芝笔记本的方法。
1.东芝笔记本开机不亮类故障故障现象:开机不亮故障就是能开机,但不能点亮显示屏。
按下开机键的时候,电源指示灯和硬盘指示灯亮了,CPU风扇也转动了,也能正常开关机,但外接显示器不显示。
故障部位:发生开机不亮故障时主供电和系统供电电路基本正常,主要是信号系统出现故障。
这里需要指出,信号系统不是纯粹的软件系统,信号系统包括BIOS、总线、控制信号、时钟信号等,信号不正常是由于硬件错误引起的。
解决措施:这种故障涉及的面很广,CPU、南桥、北桥、时钟电路、BIOS和显示电路均会造成此类故障,可以采取以下办法维修:(1)利用可调电源,根据电流值初步判断故障的范围。
(2)利用主板诊断卡,根据故障代码和指示灯确定故障部位。
(3)用万用表测量关键信号,包括BIOS、总线、控制信号、时钟信号等,判斯故障范围。
易损元件:时钟电路,造成时钟信号不正常。
复位电路,造成复位信号不正常。
CPU工作电路中条件不具备,造成开机不亮故障。
2.东芝笔记本不开机类故障故障现象:不开机是指笔记本电脑不能加电,即按下开机键,笔记本电脑没有任何开机现象,如电源指示灯和硬盘指示灯不亮,CPU 风扇也不转,就如同没有按下开机键一样。
故障原因:不开机故障是由于供电电路出现故障,或者负载有严重短路,也可能是与开机有关的其他电路出现问题。
解决措施:在维修的时候首先要排除短路的情况。

在最后,为了能方便地使用第二部分的内容,提供了基本的维修判断的思路。
第一章电脑维修的基本原则和方法电话判断的基本原则和方法上门服务前的准备z 电话判断z 准备备件这里所述原则、方法等是第二部分分类判断的基础,需要认真遵守执行。
§1.1 进行电脑维修应遵循的基本原则:一、进行维修判断须从最简单的事情做起简单的事情,一方面指观察,另一方面是指简捷的环境。
简单的事情就是观察,它包括:1、电脑周围的环境情况——位置、电源、连接、其它设备、温度与湿度等;2、电脑所表现的现象、显示的内容,及它们与正常情况下的异同;3、电脑内部的环境情况——灰尘、连接、器件的颜色、部件的形状、指示灯的状态等;4、电脑的软硬件配置——安装了何种硬件,资源的使用情况;使用的是使种操作系统,其上又安装了何种应用软件;硬件的设置驱动程序版本等。
东芝(Toshiba)解密方法及工具Toshiba笔记本解密的方法有KeyDisk、并口解密狗、USB解密狗、重新刷BIOS、修改密码芯片数据等。
最新的迅驰机器解密需要售后服来算密码,有点像DELL解密了。
、并口解密狗解密并口东芝解密狗只支持一些比较老的机型,如东芝2410、1410等,直接就把密码清除掉了。
有些东芝本本没有并口,可以通过转接卡来接为并口进行解密。
、使用解密编程器读取密码数据以Toshiba Tecra M1为例,该机型的笔记本电脑,有两个密码,一个是用户密码(开机时询问,需要输入),一个是管理员密码(在BIOS 锁定部分设置)。
此类笔记本,要采用读取密码芯片数据的方法进行解密:1.取下笔记本电源和电池。
2.拆笔记本附属设备(硬盘、光驱等)、键盘等。
(参考笔记本硬件维护手册)3.在笔记本键盘下面找到EEPROM芯片24c02w8。
4.用编程器读出EEPROM的数据。
用此方法,支持以下型号的东芝笔记本电脑的开机密码解密:ortege R100, M100, M200, S100-S113TD, S100-S213TD, M205-S810, M205-S809, R200-S214, R200-S234, M400-ST9113, M400-S4032, 00-S4031, R200-S2032, R200-S2031, M405-S8003, M400-S933, M400, R205-S2062, R205-S209, M300, R200-S2062, S100-S1133, S100-S11osmio F15-AV201, G25-AV513, F25-AV205, G15-AV501-R, F15-AV201-R, G35-AV650, G35-AV600, G15-AV501atellite R15-S822, R15-S8222, R10-S613, R10-S820, A55-S1064, R10-S804TD, R15-S829, R10-S802TDatellite Pro M10-S405, M10-S406, M15-S405, M15-S406ecra M1, M3-S311, M3-S212TD, M4, M4-S115TD, M4-S335, S3-S411TD, S3, M3-S316, M3-S336, M4-S535, M4-S515, M4-S435, M4-S415 -S315, M5-S5331, M5-ST1412, M5-ST8112, M5, M3-S737TD, M5-S433, M3-S636, M4-S635, M3-S331, M3, M2, M2Vibretto U100, U105, U100-S213shiba Satellite 1100 Seriesshiba Satellite 1715 Toshiba Satellite 1715shiba Satellite 2600 Series Toshiba Satellite 2600 Series shiba Satellite 2430 Toshiba Satellite 2430shiba Satellite 1105 Series Toshiba Satellite 1105 Series shiba Satellite 1715 Toshiba Satellite 1715shiba Satellite 2610 Toshiba Satellite 2610shiba Satellite 2435 Toshiba Satellite 2435shiba Satellite 1130 Series Toshiba Satellite 1130 Series shiba Satellite 1730 Toshiba Satellite 1730shiba Satellite 2615 Toshiba Satellite 2615shiba Satellite 2715 Toshiba Satellite 2715shiba Satellite 1135 Series Toshiba Satellite 1135 Series shiba Satellite 1735 Toshiba Satellite 1735shiba Satellite 2650 Toshiba Satellite 2650shiba Satellite 2750 Toshiba Satellite 2750shiba Satellite 1605 Toshiba Satellite 1605shiba Satellite 1750 Toshiba Satellite 1750shiba Satellite 2655 Toshiba Satellite 2655shiba Satellite 2755 Toshiba Satellite 2755shiba Satellite 1625 Toshiba Satellite 1625shiba Satellite 1755 Toshiba Satellite 1755shiba Satellite 2670 Toshiba Satellite 2670shiba Satellite 2770 Toshiba Satellite 2770shiba Satellite 1675 Toshiba Satellite 1675shiba Satellite 1900 Series Toshiba Satellite 1900 Series shiba Satellite 2675 Toshiba Satellite 2675shiba Satellite 2775 Toshiba Satellite 2775shiba Satellite 1695 Toshiba Satellite 1695shiba Satellite 1905 Series Toshiba Satellite 1905 Series shiba Satellite 2695 Toshiba Satellite 2695shiba Satellite 1110 Series Toshiba Satellite 1110 Series shiba Satellite 1700 Toshiba Satellite 1700shiba Satellite 1950 Series Toshiba Satellite 1950 Series shiba Satellite 2700 Series Toshiba Satellite 2700 Series shiba Satellite 1115 Series Toshiba Satellite 1115 Series shiba Satellite 1715 Toshiba Satellite 1715shiba Satellite 1955 Series Toshiba Satellite 1955 Series shiba Satellite 2710 Toshiba Satellite 2710、短路法适用于以下机型:telitte p100,pro p100,sateliite l10,l20,l30,pro l20,satelitte m100,M200,R100,A100,tecra a6telitte M18,M30,M20,A60,PRO M10telitte 17** series,1100,1110,1130, 1200, 1900, 2430, 3000 P20,P30, P33, A30, A70, A80, M40X, M50,M60, M70, M100 cra a3,s2,a5,a6tellite a100,equium A100,satellite pro a100, atecra m7tellite A100 (PSAA2A-02C01N)CRA A4 & Satellite M40cra s1,M1详细介绍,见光盘东芝笔记本解密工具中的PDF文件。
