Dell Precision T7500 Error code
Booted up one of our Dell Precision T7500 this morning and we get the following diagnostic light combination:
Solid amber power button and a green flashing 2 diagnostic light. 1, 3 and 4 are off.
This combination isn't in the tech manual and comes up pre bios... All fans spin but nothing else. The PSU is fine and removing all cards and memory from the board make no difference whatsoever.
Therefore wondering if anyone could shed some light on what the fault could be?

Hi klou01,
Thank you for writing to the Dell Community Forum.
Please disconnect all the cables connected from the PSU. Then connect only the power cable to the PSU, press the diagnostic button on the PSU to check if there is a green light. If there is green light then there is no issues with the PSU. Then connect the power cable to the motherboard and check if there is any beeps heard. Try with one memory, at a time in different slots. You may also try with a new coin cell battery.
Kindly get back if there are any further queries.
