Precision T7910 blinking green light LED on motherboard

My precision t7910 a couple days ago press power bottom don’t boot, no logo, no beeps, only fans sounds and nothing, the power bottom light it’s white all the time, I try a couple time and nothing.

I decide to open the case I notice blinking green light Led on motherboard, I looking about that LED Light I can’t find nothing except about orange light it’s about power bottom light code meanings.

One person Dell Forum mention about it but no answer, no answer, etc.

I hope somebody give a answer here.

I will leave a picture about it.

Thank You So Much in advance

  • Clear cmos . Hardware configuration has changed. I just got a used one from pc server place and it was doing the same thing.  the picture is just to the left of the light .  Turn the power off pull the jumper in the black circle and jump the pins in the red circle. leave it there for a moment  , put the jumoer back were it was at and reboot. should get you to bios. hope that helps
