I have a perfectly good Compaq 2930 (2010c) color HPC with dock and ac adapter at home and battery door. But the original Ni-Mh battery did not come with it. I bought two AA Ni-Mh cells off of eBay and spot welded them together with my spot welder. But I need to recreate the ribbon cable with wires. All I need to know is what the original surface-mount resister value is so I can build the pack and have the unit as a portable again.

My only other option is to forget about Ni-Mh cells and use a 18650 3.7v 2900mAh cell. and install in the dock a lithium charger system. And disconnect the old Ni-Mh circuits. But then I can only charge the unit by docking it. And is the fully charged 4.2v of the 18650 too much for the Compaq 2930 (2010c) to handle?

Never mind I figured it out myself. That is a diode not a resistor. I made my battery pack out of two NiMH AA batteries I bought off of eBay that were flat tops. I spot welded on tabs on the negative side of one and the positive side of the other. I then spot welded on a tab in between the two batteries and folded the tab between the two batteries and pushed them together and taped them tother to make one long battery with tabs for the negative and positive terminals.

I then soldered wire to the tabs and run the positive wire from the battery to the inner connector on the hpc which is the positive terminal of the hpc. Then soldered the battery's negative wire to the outer connector on the hpc which is it's negative terminal. I then soldered the diode between the center connector of the hpc to it's negative outer connector.

Now my Compaq 2930 (2010c) hpc sees it's new replacement battery and charges it as well.
When I need to change the cells in a few years. Just spot weld together another pair of cells and solder them onto the existing positive and negative wires.

PS the NiMh batteries I used were 2500mAh so I should get a good runtime out of them.

Here is a link to the batteries I purchased:
