1 Amber Light Flash Then Power Off
Precision 3630 Tower
Hi, I have the Precision 3630 Tower that won't power on. When pressing the power button you see 1 amber flash and then it powers back off again. The battery/cylinder symbol has a white light random flashing and pausing, no pattern.

Below chart are the diagnostic LED's and their meaning.
The power LED states are shown in following table.
Refer to the below Blinking Amber Pattern Table for diagnostics suggestion and possible failures.
Indicates the POWER_GOOD signal is active and it is probable that the power supply is fine.
Does not indicate a fault condition.
The BIOS will turn the LED to this state to indicate it has started fetching opcodes.
The power LED only serves as an indicator of the progress through the POST process. These LEDs do not indicate the problem that caused the POST routine to stop.
This platform does not ship with legacy 4 quad pack diagnostic LEDs. It is now relying on the power LED light blinking amber pattern to determine few failures listed in following table.
Amber LED blinking pattern: The pattern is 2 or 3 blinks followed by a short pause then X number of blinks up to 7.
The repeated pattern has a long pause inserted in the middle.
Example 2,3 = 2 amber blinks, short pause, 3 amber blinks followed by long pause then repeats.
Blinking Amber Pattern Table
The following table depicts the amber blinking patterns with possible troubleshooting resolution:
Replace the motherboard
If customer can assist to troubleshoot, narrow down the issue with PSU BIST Test, reseat cable.
If nothing works, replace the motherboard, power supply or cabling
If customer can assist to troubleshoot, narrow down the issue by reseating memory and swapping an available known good memory.
If nothing works, replace the motherboard, memory or processor
If customer can assist to troubleshoot, narrow down the issue by swapping a known good coin cell battery if available.
If nothing works, replace the coin cell battery
System is in Recovery Mode.
Flash latest BIOS version. If problem persists, replace the motherboard
CPU configuration activity is in progress or a CPU failure was detected. Replace the processor
Memory subsystem configuration activity is in progress. Appropriate memory modules were detected but a memory failure has occurred.
If customer can assist to troubleshoot, narrow down the issue with reseating memory and swapping a known good memory if available.
If nothing works, replace the memory.
PCI device configuration activity is in progress or PCI device failure was detected.
If customer can assist to troubleshoot, narrow down the issue by reseating PCI card and removing one by one to determine which card failed.
If identified the PCI card failed, replace the PCI Card.
If none of the PCI Cards failed, replace the motherboard.
Video subsystem configuration activity in progress or video subsystem failure.
If customer can assist to troubleshoot, narrow down the issue by removing one by one to determine which card failed.
If identified the card failed, replace the card.
If none of the card failed, replace the motherboard.
If customer can assist to troubleshoot, narrow down the issue by removing one by one memory to determine which one failed and swapping to a known good memory if available to confirm.
If identified the memory failed, replace the memory.
If none of the memory failed, replace the motherboard.
Possible storage device configuration in progress or storage subsystem failure.
If customer can assist to troubleshoot, narrow down the issue by removing one by one storage on motherboard to determine which one failed.
If identified the storage failed, replace the storage.
If none of the storage failed, replace the motherboard.
Memory subsystem configuration activity is in progress. No memory modules were detected.
If customer can assist to troubleshoot, narrow down the issue by removing one by one the memory on motherboard to determine which one failed. Also, combining the configuration to validate appropriate combination.
If identified the component failed, replace the component.
If none of the component failed, replace the motherboard.
Fatal system board failure detected.
If customer can assist to troubleshoot, narrow down the issue by removing one by one the component on motherboard to determine which one failed.
If identified any of the component failed, replace the component.
If none of the component failed, replace the motherboard.
Memory subsystem configuration activity is in progress. Memory modules have been detected but appear to be incompatible or in an invalid configuration.
If customer can assist to troubleshoot, narrow down the issue by removing one by one the memory on motherboard to determine which one failed.
If identified the memory failed, replace the memory.
If else, replace the motherboard.
