An audio disc or AutoPlay-enabled disc does not automatically play when it is<br />
inserted into a CD drive<br />
Symptom: An audio disc or AutoPlay-enabled disc does not automatically play when it is inserted into<br />
a CD drive.<br />
Actions:<br />
• If you have multiple CD or DVD drives installed (or a combination of CD and DVD drives), try inserting the<br />
disc into the other drive. In some cases, only one of the drives is connected to the audio subsystem.<br />
• If you are using the Windows 7 operating system, follow the action for “A CD or DVD does not work”<br />
on page 61.<br />
If this does not correct the problem, follow the action for “A CD or DVD does not work” on page 61.<br />
A CD or DVD does not work<br />
Symptom: A CD or DVD does not work.<br />
Actions:<br />
• Verify that the disc is inserted correctly, with its label up.<br />
• Make sure that the disc you are using is clean. To remove dust or fingerprints, wipe the disc clean with a<br />
soft cloth from the center to the outside. Wiping a disc in a circular motion might cause loss of data.<br />
• Verify that the disc you are using is not scratched or damaged. Try inserting another disc that you know<br />
is good. If you cannot read from a known-good disc, you might have a problem with your CD or DVD<br />
drive or the cabling to your CD or DVD drive. Make sure that the power cable and signal cable are<br />
securely connected to the drive.<br />
Unable to use a startable (bootable) recovery medium, such as the Product Recovery<br />
CD, to start your computer<br />
Symptom: Unable to use a startable (bootable) recovery medium, such as the Product Recovery CD,<br />
to start your computer.<br />
Action: Make sure that the CD or DVD drive is in the startup sequence before the hard disk drive. Refer<br />
to your “Selecting or changing the startup device sequence” on page 47 for information on viewing and<br />
changing the startup sequence. Note that on some models the startup sequence is permanently set and<br />
cannot be changed.<br />
If these actions do not correct the problem, run the Lenovo Solution Center program. If you need technical<br />
assistance, see Chapter 11 “Getting information, help, and service” on page 75.<br />
