    笔记本上的指纹识别器

    这次新买的笔记本上有一个指纹识别器,登陆的时候,可以直接使用指纹识别器来进行身份验证,这的确是非常的方便。经过了一次操作系统重装之后,发现指纹识别器中所记录的指纹信息,并不是保存硬盘之中的,而是保存在指纹识别器之中。

    有几次发现指纹识别器突然无法工作了,但是通常会在几小时之后自动恢复。上周五我洗过手之后,直接用湿手去进行指纹验证,发现识别器又不能工作了,当时也没放在心上,但是经过了一天多的等待之后,发现居然还是不能使用,心里非常的着急。本来以为这个识别器已经被我的洗手水给烧掉了,可能需要更换一个了。没想到,到了周日,识别器居然又恢复了。看来使用湿手去摸识别器,确实能够使识别器失效,恢复的时间,和进水的多少成正比。当然,请看到这篇blog的朋友不要在自己的机器上进行类似的实验,彻底无法恢复,或者给笔记本带来更大的伤害,都是有可能的。

    再也不用湿手去碰指纹识别起了。
