Solution
Press the Num Lock key. The
Num Lock light should not be on if
you want to use the arrow keys. The
Num Lock key can be disabled (or
enabled) in Computer Setup.
1. Make sure the airflow to the
computer is not blocked.
2. Make sure the fans are connected
and working properly (some fans
only operate when needed).
3. Make sure the processor heatsink
is installed properly.
Transfer data from the hard drive to
create more space on the hard drive.
Reset the two red serial port jumpers
from pins 2 and 3 to pins 1 and 2.
This reconfigures the port from
"standard" to "powered" mode. See
the Hardware Reference Guide for
instructions on resetting the jumpers.
