> Zaurus C1000 Will Not Charge, I can't get my Z to charge a battery or boot.

I've seen similar posts, but have not been able to find clear answers to this one. Please forgive me if I simply didn't look hard enough.

I have been using an SL-C1000 for about a year and have been very pleased with it up until now. I noticed I wasn't getting very long battery life (a day, maybe 1.5 days) so when I plugged it in to charge and the light blinked I figured it needed a new battery. I ordered the new battery, put it in, and the Z still won't work. I've tried reflashing it from the diagnostic menu and that does not work. I've tried several of the battery sections in the service menu. I tried charging both batteries from the charge submenu and that does not work. The battery light will come on and stay on for hours, but the battery does not charge at all. I've checked the battery voltage with a separate volt meter and no change even after several hours.

The Z does seem to respond to batteries of different charge levels. The new battery only reads 3.7V on my volt meter (not the Z's Low Battery menu). The old battery shows 4.0V. If I plug in the old battery (after turning off the Z in the service menu) the battery light will stay on for about 10 minutes and then start blinking. If I try this with the old battery the battery light just starts blinking right away. The Low Battery Menu will only show 1.1V no matter which battery is in or if I even have a battery in the unit.

The only thing that works at all is reloading the original Japanese NAND and booting from the emergency console (the one you get to by holding down 'D + B'). I booted it up by typing Qt at the prompt. It took a while, but eventually I had a Japanese ROM working. However, when I pulled the power cable, it went dead. I tried charging the unit with the Japanese console and that didn't work either. If I try turning the Z off when using the Japanese NAND it will not turn on again even though I have the power cord plugged in. It seems a little inconvenient to keep it plugged in and on AND try to learn Japanese.

I also cannot get the emergency menu to come up (the one where you pull the battery, unplug the power, hold OK, plug in the power cord, put in the battery, lock the battery and then push the ON button).

I've seen a few posts that suggest replacing a fuse or some caps on the power board, but I haven't seen any clear instructions about how to do it (getting the unit apart, pulling out the ribbon cables without damaging them, where the power board is, or a good schematic, etc.). I also would rather not tear into it if there is a simple solution OUTSIDE the unit.

The battery circuitry in the cxxxx series isn't like the cxxx's - I recall not finding the small-valued fuses (only ~3A ones) when I was looking at the schematics. So it may not be that.

Hmm. I know you tried the plastic-removal trick, but did you get rid of enough, or from the right place? It should be the plastic between the terminal and the case seam. If one of the terminals still isn't quite making proper contact it may be giving you these problems.
