关于D80突然丢失电量的故障
在新疆旅行途中发生了好几次使用过程中突然误报电量不足的情况，需要重启机器才能正常拍摄，一直耿耿于怀。
浏览flickr的时候发现许多国外用户也遇到了同样的问题，最后的结论是镜头与机身的接触不良的问题，解决方法是重新安装镜头。
回家的第二天我已经拆卸并重新安装了镜头 ，希望这个问题不要再出现了。
Dead Battery Syndrome

原文引用如下：
There is a very long thread about this on the Nikonians. According to it, this seems to be in fact due to an issue between the lens contacts and the body contacts. The link below leads to one of the summary they did and I think it will be of interest to you if you are concerned with this issue

Some people there mention that removing the battery stopped working as a fix at some point.
One advice is to remove the lens and put it back. I have read in one of the posts that a false contact could lead to a powersurge then triggering the low battery signal…
I had this issue a few days after I got my D80+18-200VR. As I also had hot pixel issues I have just exchange the body and never had this issue again.
I thank the web for the knowledge sharing, I would never have thought that a battery symptom could have come from a lens mount issue!
One important point is that they also pinpoint in that thread that this is really a very rare issue. But an annoying one if you don’t know how to fix it and you are on an assigment or in vacation without an internet access to help you!
