Inspirion 9400 wont start or charge

Question

Hi. I have a problem with my 2 year old Inspiron 9400. During the past weeks it has become worse and worse and now it is almost dead... Here are the symptoms: When I power on, the power-on-LED and the bluetooth-LED comes on for about 2 seconds then they become black and the computer is dead. This happens regardless if the power cable is connected or not. Sometimes if the computer has been left alone for a couple of hours, or when I have removed every component inside the computer and put them back, it starts up showing the bios screen and then hangs. Only difference is when I remove the two pieces of RAM, then three of the LEDs lit up, but the computer is still dead. I'm totally clueless. Can anyone help me? I've read something about some power jack connector, could it be it? I'd appreciate the help. /Rickard   Oh and the battery indicator on the battery shows two LEDs when I press the button.

In order, try without the battery - if it'll power up then, replace the battery with a new one. If not, try a new AC adapter.

Still nothing? You've either a power jack or an outright mainboard failure.

Thanks for your quick reply.

It's definitely not the battery, but I'll try with another adapter.

Is there some way to be sure that the power jack is broken? If I remove it and try to boot up the computer, will that work?

If the system will power up with a partially charged battery, it may be just the jack.  If it won't, it's the mainboard.
