| PowerBook 520c Battery Connector Corrosion | |
| Posted by: Pilgrim33 on 2025-05-17 19:42:25 I am replacing the capacitors on a PB 520c and I am particularly concerned about the battery connection posts on the logic board. There is extensive corrosion on the connectors, with more on one side than the other. On the one that is worst, the corrosion is rock-hard and when I chip it off, the copper connectors fall apart. Is it advisable or feasible to remove the battery connector posts from the logic board? I would like to remove them in order to clean them thoroughly, or perhaps even to replace the one that is in worst shape. It does not appear to me that they are soldered onto the logic board. Does anyone know how these can be removed? And if that's not feasible, what is the best way to clean this corrosion off of the connectors while they are still on the logic board? Thank you!   | |

You could rebuild the contacts using some sort of RF shielding cut up perhaps into thin strips and soldered back in. Also check the battery itself and bag it up you can unclip the battery cover on the 5x0 battery and slide in with a small spring to make it clip back in again. | |
