904-SATA Cabling Error

One or more SATA devices are improperly 
attached. For optimal performance, the SATA 0 
and SATA 1 ports should be used for hard drives 
before other ports.

Ensure SATA connectors are used in ascending 
order. For one device, use SATA 0. For two 
devices, use SATA 0 and SATA 1. For three 
devices, use SATA 0, SATA 1, and SATA 2.

90B-Fan Failure

The system has detected that a cooling fan is 
not operating correctly.

1.

Reseat fan.

2.

Reseat fan cable.

3.

Replace fan.

90D-System Temperature

Thermal shutdown occurred. The system BIOS 
has detected your machine was previously shut 
down to avoid overheating. Overheating may 
occur if the cooling vents are blocked or the 
operating temperature exceeds the system 
specifications. The machine should return to 
normal operation once the situation is resolved.

Make sure system has proper airflow.

90E-Power Supply Fan Not detected

Power supply fan is not connected or may have 
malfunctioned.

1.

Reseat power supply fan.

2.

Reseat fan cable.

3.

Replace power supply fan.

910–Filter Warning

Airflow filter is dirty.

Replace the airflow filter.

Interpreting system validation diagnostic front panel LEDs and 

audible codes

During the system validation phase that occurs at system startup, the BIOS validates the functionality of the 
following subsystems and conditions:

●

AC adapter

●

System board power

●

Processor failure

●

BIOS corruption

●

Memory failure

●

Graphics failure

●

System board failure

●

BIOS authentication failure

If an error is detected, specific patterns of long and short blinks, accompanied by long and short beeps (where 
applicable) are used to identify the error. These patterns will make up a two part code:

●

Major – the category of the error

●

Minor – the specific error within the category

NOTE:

Single beep/blink codes are not used.

Number of long beeps/blinks

Error category

1

Not used
