j-bro Posted July 15, 2005 Report Share Posted July 15, 2005 I have a battery pack form a solo 2150 notebook computer. It is a 10.8V , 3200 mAh panisonic battery 6500363. Does any one know were I might find a schematic for the internal board inside the battery pack? Not sure if anyone knows what I am talking about. the battery works when I "hot wire" positive lead from battery cells to positive lead to connector. There is a thermal Protector I think that I can also by pass and then the battery works to start the laptop. Just need some direction to figure out what part is wrong on the internal board. Do not want to pay 80 dollars for a new battery. Plus I love to take things apart and try to fix them. thanks for all the help.J-Bro Quote Link to comment Share on other sites More sharing options...
ante Posted July 16, 2005 Report Share Posted July 16, 2005 Hi bro,Welcome to our forum.A schematic will not be simple to find, the manufacturer likes to keep this to themselves. When you “hotwire” the battery it works you say, but does it charge normally in the computer? The reason for the question is; the electronics inside the battery is also involved in the charging even the thermal protection. I would try with another battery to make sure there’s nothing wrong in the computer itself, have you checked the leaf connectors in the battery compartment? 8) Quote Link to comment Share on other sites More sharing options...
j-bro Posted July 18, 2005 Author Report Share Posted July 18, 2005 I hot wired the battery and then left the laptop on until the power ran out. I let the battery charge over the weekend. Only a few hours at a time to make sure the battery was not getting to hot. Checked today to see were the cells were at, and they are reading that they are fully charged. I have a friend that is going to make me a circuit to run a LED that will let me know when the battery gets to a certian voltage so that I know it is time to charge it. I will be doing that this afternoon. thanks for the reply.J-Bro Quote Link to comment Share on other sites More sharing options...

j-bro Posted July 19, 2005 Author Report Share Posted July 19, 2005 I think the battery cells are pretty much dead. I am going to charge them and drain them a few times to try and see if that will bring them back. Otherwise I will buy new cells to go inside battery housing.

ante Posted July 19, 2005 Report Share Posted July 19, 2005 Hi Bro,Here is a very good tutorial: http://www.electronics-lab.com/articles/Li_Ion_reconstruct/index.html how to rebuild a pack. Good luck! Quote Link to comment Share on other sites More sharing options...
pseudoelf Posted March 17, 2006 Report Share Posted March 17, 2006 I have the Gateway 600YGR I tried to replace the cells but the PCB that controls the pack will not recognize the new cells. So the computer is tring to charge but the batteries board will not allow energy in or out.(I need to figure out how to reset it maybe that is the same problem as yours).
