My macbook wont charge batteries - help!

My 2006 13" macbook wont charge any battery. It recognises the battery but says "not charging".

I got a new battery and I have tested it in other macbooks and it works perfectly.

 

So far I have tried all combinations of on, off, sleep, restart etc.

I also did a PRAM reset and a SMC reset.

Unfortunately I dont have the startup disks so I cant do an apple hardware test.

Has anybody any ideas/suggestions?

 

I had some problems 2 years ago and replaced the hard drive and the memory, although only one of the memory slots works.

My specs are
