Hi guys,

I have a Dell Latitude 5480 that's not powering on.

When you press the power button, it just stays on for about three seconds then shuts down.

The LED lights are not turning on. And there are no beep codes.

I've tried running the BIST test and it passed.

When you plug in power, the LED light flashes white on and off forever but still doesn't power on


Many thanks,
Mel

To run the self test you said it passed it means the system has to turn on. So it runs the diagnostic tests but that's it? A 5480 may be in warranty, did you contact Dell? With how it's acting it's likely a motherboard failure.
