A CD drive letter should be present regardless of the presence of a 
CD disc in the drive. After the CD is properly inserted, data can be 
accessed just like with hard disk drives; except that nothing can be 
written to or changed on the CD. Using the proper software, a CD-
RW drive or DVD+CD-RW drive can allow CD-RW discs to be used 
like a hard drive with writing, deleting, and editing capabilities. 
Vibration is normal for all high-speed optical drives due to 
unbalanced CDs or CD print. To decrease vibration, use the Notebook 
PC on an even surface and do not place labels on the CD.
Listening to Audio CD
The optical drives can play audio CDs, but only the DVD-ROM drive 
can play DVD audio. Insert the audio CD and Windows automatically 
opens an audio player and begins playing. Depending on the DVD 
audio disc and installed software, it may require that you open a 
DVD player to listen to DVD audio. You can adjust the volume using 
hotkeys or Windows speaker icon in the Notification area.
WARNING!  If the CD disc is not properly locked onto the center 
hub, the CD can be damaged when the tray is closed. Always 
watch the CD closely while closing the tray slowly to prevent 
damage.
Using the Optical Drive
Optical discs and equipment must be handled with care because of 
the precise mechanics involved. Keep in mind the important safety 
instructions from your CD suppliers. Unlike desktop optical drives, 
the Notebook PC uses a hub to hold the CD in place regardless of the 
angle. When inserting a CD, it is important that the CD be pressed 
onto the center hub or else the optical drive tray will scratch the CD.
