|I've used this method a couple of times with success but no guarantee. It sounds like the sensor that detects the CD tray position is out of adjustment, possibly Caused by a Jammed CD or forcing the tray in either diredtion.|
Give this a try. With the Computer shut down and Power off. Unplug the Computer, turn off the surge suppressor or turn off the switch on the Power Supply (Back of the Computer Case), use a stiff Paper Clip to Open the CD Tray (there is a small hole in the CD Drive Face Plate for this). Once the tray opens, gently pull the tray out as far as it will go. DON"T FORCE IT.
Next, gently push the tray all the way back in till it latches in the closed position. Restart the Computer and see if the problem continues.
If you still have the same problem you may have to replace the CD Drive. Sometimes this can be fixed by disassembling the drive. Probably better to replace it.
Before you go out and buy a new Drive, see if you can borrow another CD drive to see if it exhibits the same problem. If the borrowed drive works OK a new Drive should solve your problem.
There is nothing to learn from someone who already agrees with you.
