About the Product Capacity Representation
Standard
About the capacity representation of the storage
The capacity of the storage device (HDD, SSD) of the manufacturer
is calculated assuming that 1KB=1,000 Bytes.
However, the operating system (Windows) calculates the storage
device capacity assuming that 1KB=1,024 Bytes, and therefore the
capacity representation of the HDD in Windows is smaller than the
actual capacity due to the dierence in capacity calculation.
(E.g. For a 80GB HDD, Windows represents the capacity as 74.5GB,
80x1,000x1,000x1,000 byte/(1,024x1,024x1,024)byte = 74.505GB)
In addition, the capacity representation in Windows may be even
smaller because some programs such as Recovery may reside in a
hidden area of the HDD.
About Memory Capacity Representation
The memory capacity reported in Windows is less than the actual
capacity of memory.
This is because BIOS or a video adapter uses a portion of memory
or claims it for further use.
(E.g. For 1GB(=1,024MB) memory installed, Windows may report
the capacity as 1,022MB or less)

Cautions on Preventing Data Loss
(Hard Disk Management)
Take care not to damage the data on a hard disk drive.
A hard disk drive is so sensitive to external impact that an•
external impact may cause loss of data on the surface of the
disk.
Take extra care, because moving the computer or an impact•
on the computer when it is turned on may damage the data of
the hard disk drive.
The company is not liable for any loss of data on the hard disk•
drive.
Causes that may damage the data of a hard disk drive and
the hard disk drive itself.
The data may be lost when an external impact is applied to the•
disk while disassembling or assembling the computer.
The data may be lost when the computer is turned o or reset•
by a power failure while the hard disk drive is operating.
The data may be lost and irrecoverable due to a computer virus•
infection.
The data may be lost if the power is turned o while running a•
program.
Sudden impact or movement to the computer while the hard•
disk drive is operating may cause les to be corrupted or bad
sectors on the hard disk.
To prevent data loss due to damage to the hard disk drive,
please backup your data frequently.

Using the Power Supply in an Airplane
Since the power outlet type diers depending on the type of
airplane, connect the power appropriately.
Since the representative gures of the power plug and
the auto adapter are used, they may dier from the actual
parts.
When Using the AC Power Plug
Connect the power plug pins perpendicular into the center of the
power outlet.
If the plug pins are not inserted into the center of the holes, the•
plug pins are only inserted up to half their length. In this case,
reconnect the power plug.
You have to insert the power plug into the outlet when the•
power indicator (LED) of the power outlet is lit green. If the
power is connected properly, the power indicator (LED)
remains green.
Otherwise, the power indicator (LED) is turned o. In this case,
unplug the power, check if the power indicator (LED) is green,
and then reconnect the power plug.
