This article provides information about the power button LED diagnostic status for the Precision T1700 Desktop Workstation.


Troubleshooting the Precision T1700 Desktop Workstation with the power button

The Precision T1700 Desktop Workstation does not share the same style-diagnostic indicators of other Dell workstation models. Instead, the state and blinking pattern of the power button LED provide a diagnostic indicator for help with troubleshooting potential issues with your computer. Each LED has three possible states: OFF, ON, or BLINKING. Use the charts below as a reference for the different LED patterns and the possible computer issues they indicate.

NOTE: The power LED state only serves as an indicator of the progress through the POST (Power On Self-Test) process. The state of the LED does not indicate the problem that caused the POST routine to stop. For a more detailed description of the POST process and how to troubleshoot issues with the computer turning on and booting to Windows, see the article Dell Computer Does Not Turn On or Boot Into Windows at the Dell support site.

Blinking amber
SLN290447_en_US__21389805201607.PowerLEDBlinkAmber
Initial state of LED at power-up.
Indicates that the computer has power, but the POWER_GOOD signal is not yet active. Refer to the table below for specific troubleshooting suggestions.
Solid amber
SLN290447_en_US__31389805225482.Power LED solid amber
Second state of the LED at power-up. Indicates the POWER_GOOD signal is active and it is probable that the power supply is fine.
Blinking white
SLN290447_en_US__41389805247451.PowerLEDBlinkWhite
System is in a low-power state, either S1 or S3. Does not indicate a fault condition.
Solid white
SLN290447_en_US__51389805279264.Power LED solid white
System is in S0 state, the normal power state of a functioning machine.
The BIOS will turn the LED to this state to indicate it has started fetching operation codes.

2 blinks > short pause >
1 blink > long pause >
repeats
Motherboard issue Reseat components (memory, expansion cards, power, and data cables) to the motherboard.
2 blinks > short pause >
2 blinks > long pause >
repeats
Motherboard, Power Supply or Power Supply cabling Perform Power Supply BIST test and reseat the power cable to the motherboard.
2 blinks > short pause >
3 blinks > long pause >
repeats
Motherboard, Memory, or Processor Reseat memory modules or swap with individual known good memory modules, if available.
2 blinks > short pause >
4 blinks > long pause >
repeats
Coin cell battery Reseat the coin cell battery or swap with a known good battery.
2 blinks > short pause >
5 blinks > long pause >
repeats
BIOS Checksum Failure The computer is in Recovery Mode. Flash to the latest BIOS version.
2 blinks > short pause >
6 blinks > long pause >
repeats
Processor This pattern signifies that processor configuration activity is in progress, or a processor failure was detected. Verify that the processor fan is spinning and that the heatsink for the processor is attached and free of dust or corrosion.
2 blinks > short pause >
7 blinks > long pause >
repeats
Memory Appropriate memory modules were detected, but a memory failure has occurred. Reseat the memory modules or swap with individual known good memory modules, if available.
3 blinks > short pause >
1 blinks > long pause >
repeats
PCI Device or Video subsystem failures PCI device configuration activity is in progress, or PCI device failure was detected. Reseat the PCI cards or swap with a known good PCI card, if available.
3 blinks > short pause >

repeats
Video Subsystem failure Video subsystem configuration activity is in progress or video subsystem failure. Reseat the video card or swap with a known good video card, if available.
3 blinks > short pause >
3 blinks > long pause >
repeats
No Memory detected Reseat the memory modules. Remove the memory modules one by one to locate the problem module. Or swap with individual known good memory modules, if available.
3 blinks > short pause >
4 blinks > long pause >
repeats
Storage Subsystem failure Possible storage device configuration in progress or storage subsystem failure. Reseat the connections to the storage device, and from the storage device to the motherboard. Remove the individual storage devices one by one to locate the problem device.
3 blinks > short pause >
5 blinks > long pause >
repeats
Memory configuration or incompatible error Memory subsystem configuration activity is in progress; no memory modules were detected. Ensure the memory configuration is correct. Reseat the memory modules or remove modules one by one to locate the individual problem.
3 blinks > short pause >
6 blinks > long pause >
repeats
System board failure Fatal system board failure detected. Reseat components (memory, expansion cards, power, and data cables) to the motherboard. Remove individual components to locate the problem.
3 blinks > short pause >
7 blinks > long pause >
repeats
Possible memory failure Memory subsystem configuration activity is in progress. Memory modules have been detected but appear to be incompatible or in an invalid configuration. Reseat the memory modules. Remove memory modules one by one to locate the problem.
