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.
zUse only peripheral devices that conform to the computer’s specifications.
zConnect the devices properly, paying close attention to the condition and position of 
the connectors.
zIf 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.).
zIf the connector has holding screws, fasten the screws firmly.
zDo 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.
zDo 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 25)
zDo 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.
zImportant data saved on the hard disk should be saved 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.
zUse the security function for all important data.
(Î “Chapter 2: Security Measures” and “Chapter 4: SD Memory Card Security 
Function” in onscreen Reference Manual)
When Changing Hard Disk Partitions
zDuring reinstallation, you can divide the hard 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.

Operation
Useful Information
Using CD/DVD
‹About opening or closing the disk cover/cleaning the 
drive lens
zWhen the computer is on, be sure to use the open lever on the left side of the com-
puter or perform the ejecting operation through Windows.
When using the following software application, you cannot open the cover using the 
open lever
 When using B’s Recorder or B’s CLiP, refer to “Chapter 3: Writing to CDs” in 
onscreen Reference Manual
zTo 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
zBe 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 confirming 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
zThe disk cover can be opened up to an angle of 70 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 
70 degrees, pull it forward slowly until the stopper holds the cover in its proper posi-
tion
zDo 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
zInsert the disk securely. If the disk cover is closed without inserting the disk securely, 
it may become damaged.
zDo not access the drive until after the disk cover is closed and the DVD-ROM & CD-
R/RW drive status indicator   is off
zWe recommend cleaning the drive lens (B) with an air puffer used for camera lenses
(Do not use any spray lens cleaning products)
‹While the DVD-ROM & CD-R/RW drive is being 
accessed
zDo 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
zDo not apply excessive force on the disk cover
zDo 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
zIt may take about 30 - 40 seconds for an image recorded to a rewritable media to be 
played back
