[NTLK] eMate issues (not display cable for once!)

I am in the process of repairing an eMate. For once, it's not the display cable. I got to the hinges in time, I just had to spend forever and a day stretching out each spring. I haven't fully reassembled it yet, just enough to verify that it powers on. I noticed two odd issues.
Problem 1: I haven't soldered the speaker back to the logic board because I will need to remove the board to replace some of the plastic bits on either side (namely the PCMCIA bezel and the serial/NIC door). I've been using the headphone jack so I can hear the boot sounds and so forth and make sure the device is working. I get this low-frequency clicking. It is a very loud click several times per second (I would estimate 7). There are a few other sounds that I believe are logic crosstalking with the audio (high-frequency warbling and chirps), but the loud clicking concerns me. I didn't see anything in my quick search of the archives. I would really rather not have to get out my oscilloscope and trace the problem down. Has anyone else encountered anything similar?
Problem 2: It doesn't seem to be charging the battery. It sees that the battery is present and says "Charging", but I don't see any progress. If I don't have the eMate connected to mains power, it won't boot. The battery could just be completely flat, but it definitely booted the device a few days ago when I did some exploratory surgery. I left it alone for a bit and Extras reported "Fault". I unplugged the battery and AC power, then plugged the battery in again, plugged in AC power again, and booted it. I'll let it try to charge overnight. Before I break out the multimeter, does anybody know of other problems that could cause this?
This eMate does not have the 2010 fix yet, but I wouldn't expect a date problem to cause audio clicks or battery charging issues. Then again, I have seen weirder software problems that look like hardware problems.
