A defective battery cover on a Canon A640 digital camera must be replaced immediately if the camera is to be used without the power being interrupted. Replacing the battery cover is not complicated but is time-consuming, as most of the digital camera must be disassembled before the cover can be removed. You can replace the battery cover yourself if you are patient. The replacement battery cover can be purchased from a digital camera supply store, and the process requires no electronics knowledge.
