Charging port no longer charges

I have replaced the battery on my 3590.

The new battery (tried two different ones) was fully charged before connecting it.

However, whether I plug it into:

1) The wall charger

2) Laptop USB

3) Cradle charger

The battery will not charge.

Answer this question I have this problem too

Is this a good question?

Colin Marson , I take it worked on the new battery till it died and now refuses to charge. Did you check the port and blow any dust/debri out of port. Look in port and straighten any bent pins with tooth pick very carefully. Still no go, remove battery door and with a DVOM with charger plugged into device check plug at battery to see if charger is sending voltage to battery, if not probable loose/bad charge port,change the charge port. the link below is a tear down guide that can get you access to the charge port which is soldered to the mother board and is not a job for the newby because of the fine components and heat involved. 2nd link shows a charge port being resoldered.Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.

The difficulty is that neither the USB port nor the cradle connection seem to be providing a charge ( the battery icon does not show that it is being charged)
