7、长计算机的使用寿命；另一方面又可以为计算机的使用人员提供一个良好的工作环境，提高工作效率。所以，为了更好的工作和学习，我们必须的要运用好维修、维护好计算机，才能做到更好的效率。关键字：计算机硬件维修第一节计算机硬件一、计算机硬件的维护计算机硬件维护主要是指对主机及其一些主要的外围设备的维护，首先是对主机的维护，然后是对各种外设的维护。1.对主机的维护我们使用计算机机遇的第一个问题就是开机，开机就是给机器设备加电，加电的顺序应该是先给外设（如显示器）加电，然后再给主机加电；关机时顺序与之相反，先将

8、主机电源关闭，在将外设电源关闭。外设电源打开在先，关闭在后主要是为了避免在主机工作时外设电源的通断对主机产生冲击和干扰。19主机加电后，不能随意搬动机器、插播计算机各个接口上的卡；主机与外设之间的数据线，必须在关机以后才能安装和拆卸。计算机关机与开机之间必须有一定的时间间隔，且不宜频繁开关，一般关机与开机之间至少要隔30秒钟以上。计算机若长期不用，要尽量定期加电。2.对外设的维护一般计算机系统中不可缺少的外设有：键盘、显示器、光盘驱动器，等等。1）.键盘的维护保持键盘的清洁，特别要注意不要把水、
