Undetermined problems
You are here because the diagnostic tests did not identify the failure, the Devices
List is incorrect, or the system is inoperative.
Notes:
1. A corrupt CMOS can cause undetermined problems.
2. A faulty I2C Bus can cause undetermined problems. Check the system error log
for any I2C Bus errors; see “I2C bus fault messages” on page 141.
Check the LEDs on all the power supplies, see“Power supply LED errors” on
page 131. If the LEDs indicate the power supplies are working correctly, return
here and do the following:
1.
Power-off the computer.
2.
Be sure the system is cabled correctly.
3.
Remove or disconnect the following (one at a time) until you find the failure
(power-on the computer and reconfigure each time).
