Troubleshooting Dell inspiron 1545 laptop not charge new battery issue

Dell inspiron 1545 laptop works with power adapter, but won’t charge the new laptop battery

Question: My Dell Inspiron 1545 works fine with or without the ac adapter plugged in if the battery is charged. The laptop will not charge the battery, however. I can charge the battery with another charger, reinstall it, and the laptop works until the notebook battery is depleted. There appears to be something in the BIOS that is keeping the charging current from going to the battery.

The Dell Inspiron 1525 Laptop AC Adapter powers up and operates the computer very well. Even with the laptop shut off and the adapter plugged in it will not charge the battery. The charging circuit is not working in the laptop. There appear to be two options; (1) there an electrical problem in the charging circuit that prevents it from charging the battery, or (2) there is something in the software controlling the charging circuit that is preventing charging. If we assume the software is preventing charging it could be because the software is corrupted or because it was designed to discriminate between batteries and it does not like the battery connected.

I have tried two different batteries, both of which will charge up to full capacity with an external laptop charger, as indicated by the laptop battery test, and each will operate the laptop until they run down.

Has anyone experienced this problem before?

Answer: If you use your laptop with just the ac adapter, without the battery, is it working? If it is, the problem is the charging circuit on the motherboard, that has nothing to do with the BIOS. If it is not, test the laptop charger if it is working and check where it plug in the laptop is the socket is not loose.

It work on power adapter and with the Dell inspiron 1545 notebook battery at full charge but it wont charge the battery that is a power issue on the charge system in the laptop ,if you use the dell batery it should work i would find a dell service center to test that charging circuit.
When your laptop will be disassembled, if you need help just ask, the problem could be just a coil who prevent the battery to be charge.
