Network Adapter / Ethernet Problems
The Ethernet adapter does not work
• Make sure the physical connections on both ends of the cable
are good.
• The hub or concentrator may not be working properly. Check to
see if other workstations connected to the same hub or
concentrator is working.
The Ethernet adapter does not appear to operate in the
100Mbps transmission mode
• Make sure the hub you are using supports 100Mbps operation.
• Make sure that your RJ-45 cable meets the 100Base-TX
requirements.
• Make sure the Ethernet cable is connected to the hub socket
that supports 100Base-TX mode. The hub may have both
10Base-TX and 100Base-T sockets.
Performance Problems
The computer becomes hot
• In a 35
o
C environment, the certain areas of the computer’s
back case are expected to reach 50 degrees.
• Make sure the air vents are not blocked.
• If the fan does not seem to be working at high temperature (50
degrees Celsius and up), contact the service center.
• Certain programs that are processor-intensive may increase
the computer temperature to a degree where the computer
automatically slows down its CPU clock to protect itself from
heat damage.
The program appears stopped or runs very slowly
• Restart the computer.
• This may be normal for Operating System when it is
processing other CPU-intensive programs in the background or
when the system is accessing slow-speed devices such the
floppy disk drive.
• You may be running too many applications. Try to close some
applications or increase system memory for higher
performance.
