I have successfully cut open the battery case and replaced dead cells but I have 0 volts out at the connectors. I notice a small dip switch on the battery circuit board that is held depressed by the top half of the case. Does the circuit board in the battery have to be reset once the case is opened in order to work again? If so how? Or are there mini fuse links?

Yes & no. Depends on the battery?? List the numbers off the battery and I'll look up your battery board and see if it can be reset. Wouldn't hurt to give "all" the numbers off the laptop also. Very few boards can be reset. The manufacturers have gotten smarter over the years and have made changes to prevent DIY repairs.

I forgot. If you can take a quality picture of the circuit borad so I can read the numbers on the chipsets it would really help. It would help me track down the smart chip data. Post the pic on a pic host like http://www.imageshack.us/ or one of the other ones.

Wow, your battery is only $65 U.S.  The cells you bought to rebuild it had to be that much??

I really need some numbers off the battery board or the chipsets on the board to get a good view of the circuits your dealing with. Like I said, a pic of the board would do wonders in my search effort. Maybe just list the data on the chipsets on the board?

Here are some links to battery rebuilds, for reference, but not your model.

This one has a good explaination for the reprograming on a smart chip.
