it could be possible that changing the dc jack at the back may fix the problem however it could be a faulty new battery as ive had a few copies (not original) which would work for a week or so then die or others which wouldnt work at all, i finaly splashed out on a new original battery and it hasnt let me down and i bought it over a year ago.

Hope this helps

Testimonial: "Thank you. I will contact the battery supplier."
