NUC8 no power button menu no front panel LED

[efcoc]

My NUC8i7BE does not boot anymore. The +5V standby green LED on the board is on, but there is no LED on front panel nor on power button. There is also no HDMI display. The USBs have power. I've tried to place bios on USB stick and power up with security jumper removed, but still nothing happening. I am not able to get any power button boot menu to show up.

Sounds like either a power component on the board has failed or the power brick is unable to generate the amperage necessary for normal operations. I would attack the latter possibility first; try using a different power supply.

Hope this helps,

I do see 3.3V on the front panel header for the power button switch. Can this possibly be a corrupted bios? 

[n_scott_pearson]

Yes, that's a possibility as well. Did you interrupt an update?

[efcoc]

No, was not doing an update. I was only blowing dust off from the motherboard while power was removed. The PC was kind of running hot before.

[efcoc]

Is there a way to program the bios in this case?

[n_scott_pearson]

It you can't do it via CMOS reset followed by jumper-based BIOS Recovery, then no, there is no way to update it.

Found the problem was that bios battery was totally dead. I replace one, NUC is now booting up normally.
