[QUOTE=Albert;2784637]It is possible to open the drive & power the computer on, yes. I do not advise it, but it is possible.
Do not try to put a disc in the drive while it is open. There is a magnetic clamp in the lid of the drive which keeps the disc in place. Without the lid, the disc will fly out & potentially cause more damage.
You can see if the motor still tries to spin, and see if the optical pickup moves back & forth while checking for a disc.[/QUOTE]
There should also be a quick flash from the laser diode in the optical pickup when it looks for a disc.
Should also mention… Caution: Don’t look directly at the laser.
