Hello together,

i'm having the exactly same problem with a friends G5 SE 5505.
He told me, that he updated Bios/ UEFI and after that the 2,5 LED status appeard.
I'm not able to flash the BIOS with a USB Stick.

The Dell Web Page says, that you have to press ESC + CTRL and plug in the power cabel to flash Bios, but its not working. Display stays black and the LED status is blinking.

I taked out the cmos battery and unplugged the battery power cabel, pressed the power button for 30 sec to reset the Bios, but still not working.

Service...
