Many a time, a CD might not work on a laptop. There can be many different reasons behind this. In such cases, the first thing to do is to check if the CD is really the issue. Next, you could try running the hardware and devices troubleshooter. You could also test the drive for a hardware failure and check the device manager and the drive status. After this, you can enable auto-play. And finally, you can restore the laptop to the earlier state. However, there can be other reasons as well.
