hard disk space. This may account for the apparent hard disk capacity deficit.
Further Technical Explanation: The nominal capacity of the hard disk is
expressed in the decimal system, 1000 bytes. But the actual hard disk capacity is
expressed in the binary system as 1024 bytes (For example, a nominal capacity of
1GB is 1000MB, while the actual capacity of 1GB is 1024MB).
The capacity of the hard disk shown in Windows can be worked out according to
the calculations in the following example:
The nominal capacity of the hard disk is 40GB, while its actual capacity
should be: 40 x 1000 x 1000 x1000/ (1024 x 1024 x 1024) = 37GB.
If the Service partition of 3GB - 3 x 1000 x 1000 x 1000/ (1024 x 1024
x1024) = 2.79GB is subtracted, the capacity of the hard disk shown in the
system can be obtained.
The capacity of the hard disk as calculated using this method may be slightly
different from the actual capacity due to the rounding of totals.
5.5 Special considerations for troubleshooting Windows
Record the following information that may be useful later when troubleshooting
system problems:
1. The serial number of the software. The serial number is shipped labeled on the
computer and is also provided separately by the manufacturer. The Help Center
is unable to retrieve this number.
2. The drivers for this computer model support Windows XP or Windows Vista
systems.
3. When you use the Windows Media Center to watch TV, pay particular attention
to the following:
• In the following two situations, you must re-save the channel list:
a. When you change your TV signal from digital to analog, your saved
channel list for digital TV is deleted. When you want to watch digital TV
again, you must create and save a new channel list.
b. When you change your TV signal from analog to digital, your saved
channel list for analog TV is deleted. When you want to watch analog TV
again, you must create and save a new channel list.
• Before you can watch teletext programming, you must set the TV tuner input
signal to analog.
