Hello, I have a Windows XP Laptop which is about 2 years old. The CD/DVD drive will not open but there is a green light coming from it. I have managed to open it by sticking a paper clip in the hole but both DVD's and CD's are not being recognized by it. If I try to run it, my computer says it is unavailable. Does anyone have any idea how to fix this? How can I check if there is power running to this part of my computer?
