Hello all, So I write a finance final tomorrow morning and my financial calculator decided to quit working on me. The screen would flash as it turned off and on rapidly, almost as if there was a loose connection. So I popped 'er open and here is what I found: http://i.imgur.com/UdASBX1.jpg It looks like the red wire needs to be attached to the other side of the battery, but when I hold it there, it does not turn on. It also doesn't look like anything was soldered on to that side of the battery before. I'm also confused by the weird metal piece. Thanks in advance.
