Dell T7910 does not boot, blinking led on motherboard
Hello,
I have just bought a refurbished T7910.
I try to power on it.
The fans ramp up the power button is steady white but then a blinking yellow light starts blinking on motherboard and then it does not boot.
I have read T7190 troubleshooting manual but it talks about front led blinking sequence. It does not talk about motherboard led. And the motherboard led has no sequence it is half on half off.
Can you help me?
Thanks,
Mario

Try the following forum post. Especially the post by RoHe. It may be a PSU related problem.

This sounds very similar to the problem that I'm having with my Dell that is the same model as yours here's a link to my thread.

Did you ever solve the issue?
