Useful Information
Using CD/DVD
‹Before using the drive
z Do not expose the DVD-ROM & CD-R/RW dr ive to excessive smoke that may leave 
a residue, e.g. oil smoke, or tobacco smok e. Doing so could shorten the life of the 
drive lens.
‹ About opening or closing th e disk cover/cleaning the 
drive lens
z When the computer is on, be sure to us e the drive power/open switch on the front 
right of the computer or perform th e ejecting operation through Windows.
When using B’s Recorder or B’s CLiP, you cannot open the cover using the drive 
power/open switch. Refer to “Writing to  CDs (B’s Recorder/B’s CLiP)” in onscreen 
Reference Manual.
z To remove a disk when the disk cover cannot be opened or when the computer is 
powered off, insert a pointed object (e.g., the  bent-out tip of a paper clip, or the tip of 
a ballpoint pen) into the emergency hole (A), and move in the direction of the arrow.
z Be careful not to do any of the following when the disk cover is open:
• Do not close the display.
Be sure to close the display only after c onfirming the disk cover is closed. If the 
disk cover is open, the LCD may become damaged.
• Never insert foreign objects such as  paper clips into the DVD-ROM & CD-R/RW 
drive. 
This could cause it to malfunction.
z The disk cover can be opened up to an angle of 80 degrees. Do not force the cover 
open any further.
If a hand or other object touches the disk cover and accidentally opens it wider than 
80 degrees, pull it forward slowly until the stopper holds the cover in its proper posi-
tion.
z Do not leave the disk cover in the open position or touch the lens.
Over time, dust may build up on  the lens, or on a disk. This may result in a read or 
write malfunction.
z Insert the disk securely. If the disk cover is  closed without inserting the disk securely, 
it may become damaged.
z Do not access the drive until after the disk  cover is closed and the DVD-ROM & CD-
R/RW drive indicator is off.
z We recommend cleaning the drive lens (B) with an air puffer used for camera lenses
(Do not use any spray lens cleaning products.)
‹Internal DVD-ROM & CD-R/RW drive connection inter-
face
z The internal DVD-ROM & CD-R/RW drive uses a USB connection. When removing 
PC Cards, SD memory cards, or other  USB devices, the internal DVD-ROM & CD-
R/RW drive is displayed as one of the [USB Mass Storage Device]. The internal 
DVD-ROM & CD-R/RW drive cannot be re moved, so do not select [Stop].
‹While the DVD-ROM & CD -R/RW drive is being 
accessed
z Do not open the DVD-ROM &  CD-R/RW drive or move the computer while the DVD-
ROM & CD-R/RW drive is being accessed.
Doing so could cause the disk to shift position, which may damage the disk, or 
cause the DVD-ROM & CD-R/RW  drive to malfunction.
After running an application involving access to a disk, do not open the DVD-ROM & 
CD-R/RW drive until after the application has been closed.
z Do not apply excessive force on the disk cover.
z Do not operate the drive power/open switch.
z Do not shock the computer by removing or  inserting cables and cards, etc. This may 
result in a read or write malfunction.
‹ About recognition of media
z It may take about 30 - 40 seconds for an image recorded to a rewritable media to be 
played back.

Operation
Useful Information
Use of Peripheral Devices/Internal Hard Disk
Pay strict attention to the following points to avoid damage to the computer, peripheral 
devices, cables, etc.
Also, in addition to following this manual and the onscreen Reference Manual, carefully 
read the instruction manuals for the peripheral devices being used.
z Use only peripheral devices that confor m to the computer’s specifications.
z Connect the devices properly, paying close a ttention to the condition and position of 
the connectors.
z If a connection cannot be made easily, do not apply undue force; check once more 
to confirm the condition and position of  the connector (alignment of pins, etc.).
z If the connector has holding screw s, fasten the screws firmly.
z Do not carry the computer with cables attached, and do not pull on the cables force-
fully.
To Protect Data
Keep the following.
zDo not expose your computer to shock.
Use care when handling your computer, shock may damage your hard disk or make 
your software applications, and data unusable.
z Do not power off your computer while software applications are running or 
hard disk drive indicator   is on. 
Properly shut Windows down from the  [start] menu to avoid problems. (Îpage 24)
z Do not place the computer close to objects that emit electromagnetic waves 
(magnets, electromagnetic bracelets, etc.).
The data saved on the hard disk may be erased.
z Important data in the hard disk should be backed up regularly (e.g., in case of 
failures, unexpected data updates, erasure, etc.).
Regular backups are recommended as a means of minimizing damages in the 
event of trouble.
z Use the security function for all important data.
(Î  “Security Measures” and “SD Memory Card Security Function” in onscreen Ref-
erence Manual)
NOTE
z You may hear a mechanical “click” sh ortly after the hard disk indicator has 
turned off when there has been no input from a key or device operation, when 
the computer enters the standby or hibernation mode, or when Windows is shut 
down. This is the sound of the head shifting positions, to reduce power con-
sumption or to protect the hard disk from  shocks. This sound does not indicate a 
malfunction. 
When Changing Hard Disk Partitions
z During reinstallation, you can divide the ha rd disk space into two partitions by exe-
cuting: [Make two partitions , for the operating system and data, and reinstall Win-
dows to the operating system partition].
Confirm the minimum partition size required for the OS by checking the screen dur-
ing the reinstallation.
If you want to create three or  more partitions, after creating an OS partition and a 
data partition during the reinstallation, start up Windows, erase the second partition 
once using [Disk Management], and then create the partitions in the open space.
z When using the hard disk backup function, divide the hard disk into partitions when 
backup area is created ( Îpage 56). If you divide the hard disk into partitions before 
creating the backup area, the backup area cannot be created.
