About Your System 41
Solving Problems Described by LCD Status Messages
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.
Removing LCD Status Messages
For faults associated with sensors, such as temperature, voltage, fans, and so
on, the LCD message is automatically removed when that sensor returns to a
normal state. For example, if temperature for a component goes out of range,
the LCD displays the fault; when the temperature returns to the acceptable
range, the message is removed from the LCD. For other faults, you must take
action to remove the message from the display:
W1627 Power required
> PSU wattage.
Check PSU and
config.
The system configuration
requires more power than
what the power supply can
provide.
Turn off power to the
system, reduce the
hardware configuration or
install higher-wattage
power supplies, and then
restart the system.
W1628 Performance
degraded.
Check PSU and
system
configuration.
The system configuration
requires more power than
what the power supply can
provide, but it can boot if
throttled.
Turn off power to the
system, reduce the
hardware configuration or
install higher-wattage
power supplies, and then
restart the system.
