计算机硬件维修概述,告诉你硬件维修分为3个级别,硬件维修必看
计算机的硬件维修分为三个等级:
1.一级维修:以及维修也叫板及维修,其维修对象是电脑中某一设备或某一部件主板,电源,内存,cpu,硬盘,显示卡,显示器等,而且还包括电脑软件的设置。在这一级别及维修方法主要是通过简单的操作,如直接观察法,替换法,插拔法,最小系统法等方法来确定故障部件和维修电脑。
2.二级维修是一种对元器件的维修,它是通过一些必要的手段来定位部件或设备中有故障的元件器件,从而达到排除故障的目的。假如是二级维修,不仅要判断出是哪个部件,还要判断出是该部件上的哪一个器件或元件出现故障,并修复有故障的元器件,才算完成维修任务。

3.三级维修:三级维修也叫线路维修,就是针对电路板上的故障进行维修。如果是线路设计或线路故障引起无显示,就需要三级维修人员来维修,这些人往往是系统的设计开发人员。
从三个级别的维修呢,内容难高一级的维修,必然包含着第一集的维修,且一级维修是所有级别维修的基础。但在实际的生活当中,需要进行三级维修的电脑故障是很少很少的,最多的是二级维修以及一级维修。但是在电脑行业中,一级维修的地位变得越来越重要,现在在电脑维修中主要采用的是一级维修。
在计算机的一级维修中,主要的工作有。
a调整电脑的运行环境,硬件的或软件的。
b利用已有的知识经验,相关资料及相应的维修方法判断并定位故障所在的部位,然后更换有故障的部件或设备。
一级维修虽然简单,但是却需要维修人员,有较丰富和较广泛的知识和经验,其中包括对操作系统应用软件的认识和理解,对电脑系统的认识和理解,甚至应该对构成电脑部件的各元器件也有一定的认识。
2.部件与部件及维修也叫一级维修,板级维修。分为外围部件和主机部件。
3.器件与器件级维修,也叫二级维修,元器件的维修。
