Why is the hard drive capacity displayed by the OS be different from its
nominated capacity?
Most users may have discovered that the capacity of a 10GB hard drive
will become 9GB when displayed from the OS; and 20GB become 19GB,
40GB become 38GB..., etc. The bigger the capacity, the bigger the
difference. It is because hard drive makers and OS developers calculate
hard drive capacity in different ways. As a result, the nominated capacity
is different from the exact capacity displayed by the OS.
Calculation of hard drive
capacity by drive makers
1GB=1,000MB
1MB=1,000KB
1KB=1,000 bytes
Example of a 40GB hard drive:
Calculation by drive makers
40GB=40,000MB
=40,000,000KB
=40,000,000,000 bytes
Exact capacity of a 40GB hard drive displayed in the OS:
40,000,000,000÷1024÷1024÷1024=37.2529 (GB).
Furthermore, when you partition a hard drive, the system will reserve
some space on the drive for system files. Therefore, the total capacity of a

I hear noise when connecting an earphone to Joybook.
The instructions below will guide you through the troubleshooting
process.
•
Connect the earphone to other devices, such as a radio to see if you can
still hear that noise. If the noise persists, the earphone may be out of
order.

If you can hear the noise only when inserting, it is the result of high
instantaneous current. It is a normal phenomenon.
How can I reduce the wearing of the screen spindle when I open the
screen?
We suggest that you open and close your screen gently and slowly with
both hands. Apply force evenly on both hands to reduce spindle wearing
and prevent deformation or breaking of spindle due to uneven force
application.
What should I do if a program in Windows freezes?
If your system freezes, press <Ctrl> + <Alt> + <Delete> keys
simultaneously, click Applications under Windows Task Manager, and
then right-click on the application that freezes and click End Task.
Why is my Joybook running so hot? Is it normal?
Yes. Because all the hardware is in such cramped quarters, it tends to get
hot. You should avoid using your Joybook on blankets, bed, or other
materials that keeps the heat in.

inactivity?
This is the default setting of Joybook to conserve battery power. Joybooks
are configured to use the power saving feature. You can go to Control
Panel, Performance and Maintenance, and Power Options in Windows to
adjust the setting manually.
