WarningRadio frequency wireless communication can interfere with equipment on 
commercial aircraft. Current aviation regulations require wireless devices to be 
turned off while traveling in an airplane. IEEE 802.11 and Bluetooth 
communication devices are examples of devices that provide wireless 
communication.
WarningIn environments where the risk of interference to other devices or services 
is harmful or perceived as harmful, the option to use a wireless device may be 
restricted or eliminated. Airports, hospitals, and oxygen or flammable gas laden 
atmospheres are limited examples where use of wireless devices may be 
restricted or eliminated. When in environments where you are uncertain of the 
sanction to use wireless devices, ask the applicable authority for authorization 
prior to using or turning on the wireless device.

following logos:
If your drive has this 
logo...This is your drive 
type...Use your drive for...

Using a DVD drive
Using a tray-load DVD drive
[
To insert a CD or DVD:  
1Press the eject button on the CD or DVD drive. After the 
tray opens slightly, pull the disc tray completely open.
2Place the disc in the tray with the label facing up, then 
press down carefully on the disc until it snaps into place.
3Push the tray in until it is closed.
To remove a CD or DVD:  
1Press the eject button on the CD or DVD drive. After the 
tray opens slightly, pull the disc tray completely open.
2Carefully lift on the edges of the disc until it snaps off 
of the spindle. Important
Prerecorded DVDs and DVD drives contain regional codes that help control 
DVD title exports and help reduce illegal disc distribution. To be able to play a 
prerecorded DVD, the disc’s regional code and your DVD drive’s regional code 
must match.
The regional code on your DVD drive is determined by your notebook’s delivery 
address. The regional code for the United States and Canada is 1. The regional 
code for Mexico is 4. Your DVD drive’s regional code must match the regional code 
of the disc. The regional code for the disc is on the disc, disc documentation, or 
packaging.
ImportantWhen you place a single-sided disc in the tray or slot, make sure that the 
label side is facing up. If the disc has two playable sides, place the disc so the 
name of the side you want to play is facing up.
TipFor information about cleaning a CD or DVD, see “Cleaning CDs or DVDs”

Setting up an optional RAID
About RAID
RAID (Redundant Array of Inexpensive/ Independent Disks) lets 
your notebook use multiple hard drives more efficiently. Your 
notebook supports RAID 0 and RAID .1.
RAID 0 for performance
RAID 0 lets your notebook see multiple hard drives as a single 
drive. This type of RAID can increase file access speeds, which 
is important if you work with video editing, sound editing, and 
high-performance games. RAID 0 is also an affordable way to 
increase your total file storage capacity.
How it increases performance
All hard drives have limitations on how fast they can read and 
write files. If half a file is stored on one RAID 0 drive and the 
other half on another RAID 0 drive, each drive only has to read 
half of the file. So, the entire file is accessed by the notebook 
up to twice as fast. If the entire file happens to be stored on 
only one of the drives, the file is accessed at the same speed 
as if it were on a standard hard drive setup. Dividing up files 
between multiple hard drives like this is called striping.
In the graphic below, each letter represents a unique block of 
data, and each column represents a separate hard drive.Tip
Your notebook must be turned on to remove CDs and DVDs using this 
method. If you do not want to turn on your notebook, manually eject the disc 
by inserting an opened paper clip into the manual eject hole.
