Question about Computers & Internet
Dell PA-10 & PA-12 have internal serial ROM chips that communicate with the PC via the tiny center pin in the powerr plug.
If that pin gets bent or is not making proper contact, the laptop USUALLY complains and runs from AC adapter but refuses to recharge the battery ..

It may not be the power supply. The Battery can only take 500 charging cycles in it's lifetime. the battery could have failed or the chip on the motherboard that regulates voltage to the battery may have failed.
Easy test for power supply is with battery removed if it still powers up the laptop than the voltage and amperage are sufficient.
