电脑键盘使用的时间久后难免会出现些问题,常见的就有键盘失灵等情况。有网友反映自己的电脑键盘失灵个别字母不灵怎么办,影响正常的键盘操作。下面教下大家键盘失灵个别字母不灵的解决方法。
一、键盘失灵应急方法
1、鼠标右键左下的开始菜单打开【运行】,复制粘贴【osk】输入进去。(如果是osk键用不了,那就在别的电脑使用u盘拷贝字母文档进电脑,再复制粘贴)
2、然后就可以打开屏幕键盘来应急操作了。
二、数字小键盘失灵
台式电脑上的数字小键盘失灵的话,大概率是按了Numlock键关闭了小键盘,辨认方法可以看键盘上的指示灯是否是亮的,再按一次Numlock键就可以使用了。
笔记本键盘失灵的话,因为笔记本电脑键盘的空间有限,在设计的时候把数字小键盘的功能融合在字母键里了,可以按fn+Numlk键就可以切换字母/数字输入。
三、键盘驱动导致键盘失灵
驱动问题导致的,我们可以通过更新键盘驱动解决,具体的步骤如下:
1、在桌面上依次打开开始菜单——控制面板——键盘选项。
2、切到硬件选项卡,点击属性。
3、切换到驱动程序页,点击更驱动程序。
4、选择自动更新,等待更新驱动完成即可。
四、部分按键失灵
部分按键失灵一般是因为电脑键盘内部线路板有毛病,键盘内部线路板或导电塑胶长期不清洁有灰尘污垢太多,从而使电路无法接通就会导致部分按键失灵。
如果是这个原因的话,我们就要清理键盘,将里面的污垢灰尘,碎渣清理干净。打开键盘用无水酒精清洗一下键盘内部,如果里面有一层比较透明的塑料薄膜,请揭开后再清洗。
以上便是键盘失灵个别字母不灵的解决方法,希望能帮到大家。
