Answer to: Optical drive not spinning upThere is a mechanical break for the DVD disc. It is released when the cover is lowered. 4 weeks ago my friends came to me with same "disc not spinning issue" and i found that the small plastic lever molded on the cover at the right back side is broken and thus not allowing the break to be released. The spindle motor is gentle so it has no power enough to spin the disc with the break on. I simple removed the break. It helps for disc to stop quicker when cover is open accidentally and its not big deal if u remove the brake. Just wait 5 more seconds before you take the disc off.
