I have one Inspiron B130, I bought it used and with the advise that the AC adapter was bad, so I bought an ac adapter new and the laptop works perfect but the battery doesn't take charge. I bought a new battery but with this one I'm having the same problem, it won't take any charge.
Possible when the old AC adapter blew it took part of the power management circuit with it, This is the circuit that detects and charges the battery, I'm not sure whether this a seperate replaceable daughter card or whether it is part of the main motherboard. you will need to investigate this (or send it for a service)

When I connect the laptop to the wall outlet with the laptop turned off, the led that show if the battery is charged or discharged steady turn on green but later change to flashing yellow. I don't know if this is a useful tip to know what is the problem.
I bought a new battery for my dell inspirion b130 notebook, and it still wont hold charge, without the powercord and adapter.
