Dell Inspiron 1721-Battery Works-A/C not

[gigabyte]

I would appreciate any help here. Hopefully someone else had this happen. I have a Dell Inspiron 1721 that will work just fine when using battery for power, but when I plug in the A/C adapter it will not see the battery or use the power from the A/C adapter.
If I remove the battery it will not power on, nor does it charge the battery. I did not see anything burnt or otherwise obvious. Any help would be great!! Thank you

hi
and please resolder the dc jack even if solder looks ok.

Doesn't Dell use a 1-wire ID system in their power supplies, and if that goes faulty the adapter won't be detected by the BIOS and won't work?

Yes, but IIRC that throws an error.

gigabyte, have you tried another dell brick? If you were local I'd hook you up (I'm the Dell Latitude D series hoarder of the greater Louisville area )

Thank you for the response - I did re-solder and that did not correct it. I will replace it and see if that fixes it. Txs
