Q: Charging problem - no light on the connector and slow charging.

Hello,

I have problem with my MacBook Pro A1278, Late 2008. From yesterday I had problem with charging. The light on the connector is not showing either green/red color. I get icon on the battery with a service key on it and message: Condition - Replace now, Battery is not charging.

In fact for 2 hours charging the battery, which is plugged in the electricity, moved from 18% to 31%, but really slowly. If I plug out the cable, the mac stops imediatelly.

My question is: It is possible the problem with the lights (green/red) to refer to the old battery, because yesterday it was showing me colors? I also try different charger and the same thing. Or the problem could be on the motherboard, some fault? I measured the Voltage and on the charger and in the Pins inside the mac it is around 16,7V. Till yesterday the mac stayed on battery for 1, sometimes hour and a half before next charge. Other thing is that if I remove the battery from mac, it won't start anyway.

Can I test something?

Here is some info of the battery:
