Solving Problems Described by LCD Status Messages (Optional)
The code and text on the LCD can often specify a very precise fault condition
that is easily corrected. For example, if the code E1418
CPU_1_Presence
appears, you know that a microprocessor is not installed in socket 1.
In contrast, you might be able to determine the problem if multiple related
errors occur. For example, if you receive a series of messages indicating
multiple voltage faults, you might determine that the problem is a failing
power supply.
