Thanks for all the info!
Since my last post I have reset the NVRAM, formatted the hard disk and reinstalled Snow Leopard. No luck.
I read on some Apple board to try and remove the battery, but in an official apple document I read that only authorized apple shops should try to remove the battery on my model. So I am a little cautious to do that. Has anyone had any experience with updating firmware (EFI) on macbooks? Some downloads are available on the official apple site. Thx in advance!
