while running ac power adapter turns yellow and stops charging if move
My ibook won't hold a charge. While battery is in place the ac adapter light turns orange right away & computer shuts down. If I remove the battery the ac adapter light will stay green and computer works however if the adapter is slightly moved or very gently touched it will turn orange and the computer shuts down. When I pressed the button that tests the battery only one light out of 4 turns green but I can't tell if it's actually the battery since the ac adapter won't charge when the battery is in place. I got this refurbished and expect to replace the battery but I'm wondering if the ac adapter is also a problem or if there is something else I might need to replace. I would rather not replace working parts in order to diagnose the problem.
