笔记本自带有键盘,这是大家都知道的,不过有很多用户习惯都会在外接一个usb键盘来使用,玩游戏操作起来更方便,更有实感。但是有些笔记本win7系统用户遇到笔记本外接键盘没反应的问题,这是什么情况,又该怎么解决呢?下面,小编就来跟大家分享笔记本外接键盘没反应的解决方法了。
目前拥有笔记本电脑的朋友已经越来越多了,它也已经成为我们日常工作和休闲娱乐的必备之物,不过有用户也会遇到不顺心的笔记本故障,很多用户就为笔记本单独配置外接键盘,可是却遇到了笔记本外接键盘没反应的情况,该怎么解决呢?下面,小编就来跟大家分析笔记本外接键盘没反应该怎么去解决。
笔记本电脑触控板怎么关闭
1、使用其他的usb设备尝试。比如插入外接鼠标尝试。看是不是外接键盘出了问题。
2、把外接键盘尝试插到其他电脑上尝试。看是不是外接键盘坏了。

3、尝试在“安全模式”下,看能不能使用外接键盘。看是不是系统的问题。
4、尝试使用其他USB接口尝试看是否正常使用。看是不是usb接口出了问题。

5、如果其他USB接口能够正常使用,请确认你的电脑上是不是有usb3.0的接口。确认一下之前插入的是USB3.0还是USB2.0。如果是usb3.0接口,建议到华硕官网下载usb驱动。
6、在控制面板中选择键盘进行设置。看是不是设置方面的问题。
7、还是不行,可以尝试恢复系统或者重装系统。

笔记本外接键盘失灵原因:键盘电路板的按键接触点不能导电所致
1、用十字螺丝刀拆开键盘,键盘的电路板大多是由三层透明的塑料板重叠而成的,中间那层为绝缘板。

2、首先可以检查透明塑料板上的按键是否能够将触点压在一起,如果能压在一起的就正常。
3、再用万用表测量两个触点压在一起时是否能导电,各分电路是否导电等。
4、如果电路或接触点的金属膜有损坏的部分,就需要将它们连接才能导电。但这里不能焊接,因为一焊接塑料就会化掉。

5、用香烟包装用的铝箔,对折,使上下面都是银白色铝箔面,剪成合适大小后放在损坏的电路处,使损坏的电路连通,注意不要让它碰到别的电路,并用透明胶布固定好,最后重新装好键盘,再测试看是否恢复正常。

笔记本外接键盘失灵原因:检测笔记本电脑是否中毒
1、通常在我们的笔记本电脑出现失灵的状况下,既不能用外接键盘的时候,也不能用笔记本键盘的时候,可以启用屏幕键盘用来应急。
2、启动我们笔记本电脑屏幕键盘的快捷键是windows标志加R键然后输入OSK,就可以迅速地进行输入操作了。

3、如果笔记本键盘还是不行的话,就利用360杀毒软件对电脑进行全面的扫描,查看电脑是否因为中毒而导致键盘失灵,如果扫出病毒,直接利用360卫士进行杀毒就可以了。
4、同时利用360安全卫士对电脑系统进行检测,查看是否是因为系统问题导致电脑键盘的失灵,如果360安全卫士检测出系统问题进行修复即可。

笔记本外接键盘失灵原因:USB接口供电不足
1、正常情况下,笔记本电脑USB接口是不会出现供电不足的问题,因为键盘本身耗电量比较小,但是如果主板存在问题的话,就会出现供电不稳定的情况。
2、当笔记本电脑出现供电不稳定的情况时,就会出现笔记本外接键盘失灵的状况,无论你怎么按键盘,都没有任何反应,这的确挺令人着急的。
3、如果你想知道是不是笔记本电脑主板的问题导致外接键盘失灵,那么你可以用其它的键盘来进行测试,如果换另一个键盘还是有同样的问题,那么就要拿你的笔记本电脑去修理了。
4、通常也可能是笔记本电脑的某些程序或者系统补丁对USB驱动有影响而导致的问题,那么你可以做一下系统的维护,或者是重新安装操作系统试一试。
