Adapter, Battery or Both?

Hello,

I have a very old (~6 years) HP 8760w. And its battery has been bad for some time but lately a weird issue has appeared.
When the battery is in and I plug in the adapter, if the battery is empty, laptop won't start, if it isn't empty then It will turn on but the battery won't charge. Second case, without the battery in if I just plug the cable in, anew, It starts. Then if I were to put in the battery, I wouldn't get the battery charging icon, but it would definitely charge a little it.
Couple of weeks ago I was managing this by twisting the cable to get battery to charge (if it was originally in first) but that doesn't work anymore.

What could be the problem?
