Why is the hard disk capacity displayed by the OS different from
its nominated capacity?
You may have discovered that the capacity of a 10GB hard disk
becomes 9GB when displayed from the OS, and 20GB becomes
19GB, etc. The bigger the capacity, the bigger the difference. It is
because hard disk manufacturers and OS developers calculate
hard disk capacity in different ways. As a result, the nominated
capacity is different from the exact capacity displayed by the OS.
Example of a 40GB hard disk:
Exact capacity of a 40GB hard disk displayed in the OS:
40,000,000,000÷1024÷1024÷1024=37.2529 (GB).
Furthermore, when a hard disk is partitioned, the system will
reserve some space on the drive for system files. Therefore, the
total capacity of a hard disk displayed by the OS will never be the
same as its nominated capacity.
I hear noise when connecting an earphone to the Joybook.
Verify the following:
• 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 hinge when I lift up
the lid of my Joybook?
Please open/close the lid gently and slowly with both hands.
Apply force evenly on both hands to reduce hinge wearing and
prevent deformation or breaking of hinge due to uneven force.
What should I do if a program in Windows freezes?
If your system freezes, press the <Ctrl> + <Alt> + <Delete>
keys simultaneously, click Start Task Manager. Under Windows
Task Manager, click the Applications tab, and then click on the
application that freezes and click End Task.
