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.
Calculation of hard disk
capacity by hard disk
manufacturers
1GB=1,000MB
1MB=1,000KB
1KB=1,000 bytes
Example of a 40GB hard disk:
Calculation by hard disk
manufacturers
40GB=40,000MB

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 Notebook.
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.
