NUC8i7HVK failed boot

[ALand]

I have a NUC8i7HVK.  I have recently added a Wacom tablet to the front HDMI and USB and I also have a Dell 27" 1440p monitor connected to the other backside HDMI. 

I now notice that it fails to boot the first time and enters a screen asking if I want to enter the BIOS.

If I do so, all seems well.  Changing the XMP memory settings does not change this.

Thus unit is using every port now - except the mini display ports, rear Thunderbolt 3, and ethernet.

Any help is appreciated.

I understand that the power for the tablet is supplied from the USB port? If I'm correct, you should be aware that there is a power limit of 900 mA for the blue USB port. Better take power from other source or, try to use the yellow front USB port, which has power limit of 1.5 A.

Thank you Leon. That is correct and I am using the charging USB port.

Hello ALand,

Thank you for posting on the Intel® communities.  

To better assist you I would appreciate if you could confirm the following information:

• For how long you’ve been experiencing this behavior?
• Please provide a more detailed description of the problem that you are experiencing?
• What are the steps to replicate this kind of behavior?

If the problem is that the devices that are getting powered by the NUC are not turning on I consider that his may be related with the power adapter and the lack of power in the other devices.

Is that the problem that you are experiencing? Please explain.

We will be waiting for your response.

The device fails to boot properly on cold start and reboot. It gives a screen to enter BIOS or N

Pressing N enables it to boot fine.

It has happened sine I added a Wacom One Tablet, about 1 month.  Powered by the Yellow USB front port.

Since this hardware was added it always behaves the same way.

One booted up it runs well.

Try to connect the USB power cord to separate power supply instead to the NUC USB port. You may try to use 5VDC Power Supply from your mobile phone charger (or similar). You may try to supply Power to this tablet form the Thunderbolt 3 port on the rear panel. This port has 3 A charging capabilities.

Thank you for the idea. I tried this with a dedicated Anker USB charger. I got the same result.

Hello ALand,

Thank you so much for your response.

Can you please provide a picture/photo of the message that you get in the screen while booting?

Additionally, I would appreciate if you could access the BIOS and provide a picture of the “Boot Order” to the thread.

We will be waiting for your response.

Here it is.

Set your USB ports to "no detect" in BIOS. These NUC8i7HVKs are poorly made and supported even worse. My issues with hard drives was only solved by switching to "no detect". Others have had issues with USB cameras and other peripheral devices that was also solved by doing this. The "no detect" state only affects bootups, not general function of your ports once it boots to your OS.

Take a look at this thread:

[ALand]

Thank you PRomO.  I will check it out and try it out.  The Hades Canyon worked fine until I used up all of the USB ports.

Hello Esteban D.  Did you get the info that you needed to help with this?

Thanks,

Boot Order

[Esteban_D_Intel]

Hello ALand,

I was wondering if you were able to follow the recommendations provided by the community as I consider are worth trying. If so, does the behavior still occurring?

As you may know, the error message “Error: BIOS has detected unsuccessful POST attempt(s)” may

Occur when there are recent changes to BIOS, Performance Options, or recent hardware changes.

This can happen as the NUC may be trying to boot from an external USB drive or other device.

I assume that this error message won’t occur when there are no devices connected that way, is that correct? What other devices are connected via USB?

Additionally, I would like to confirm the Boot options in BIOS.

Please access the BIOS and check the following:

Advanced > Boot > Boot Configuration.

Please ensure that the “Boot USB Devices First” is unchecked. Also please disable “USB” under “Boot devices”

If the issue persists, please try enabling “Fast Boot” option and check results with me.

"I assume that this error message won’t occur when there are no devices connected that way, is that correct? 

Yes, correct.

"What other devices are connected via USB?"

External USB WD HDD self powered

Seagate USB-C HDD port powered 

Rode NT USB

Logitech C920 USB-A

Wacom - USB-A and HDMI front. Or self powered USB.

I tried all of your recommendations and this POST failure still happens.

What happens to BIOS access if I set my USB ports to "no detect" in BIOS, as suggested?  Will this not allow BIOS access without a keyboard F2 detected?

Thanks Esteban.

[Esteban_D_Intel]

Hello ALand,

Thank you for the update.

The regular BIOS access should remain the same if we select the option “No Detect” for the specified USB ports.

This is because the function of the “No Detect” option is to disable certain USB port during POST only.  

The “Fast Boot” option that I previously recommended will limit the regular “F2” to enter BIOS as this will reduce the computer boot time.

Can you please set the USB ports to “No Detect” and let me know what the outcome is.

Additionally, I would like to share with you the article Error: BIOS has detected unsuccessful POST attempt(s)

In the meantime, I will further investigate this behavior on my side. We really appreciate your patience though this troubleshooting process.

“No Detect” worked.  it will cold start and restart properly now. 

But, I cannot get into the BIOS with F2 now.  I did hold down the start button for both 3 seconds and regularly. 

Any hints?  Thank you.

[n_scott_pearson]

You should set the USB port(s) through which your keyboard and mouse are connected to Enabled. The remainder can be set to No Detect.

You can get into BIOS Setup (Visual BIOS) using the Power Button Menu (PBM). Power on holding the power button in until the button turns amber (just a few seconds). Wait and the PBM will appear. Pressing F2 once it appears should get you into BIOS Setup.

Hope this helps,

Thank you n_scott. I will try this.  Is there a schematic that tells me the USB port layout for the USB-A ports?  Thanks!

[n_scott_pearson]

See the attached diagram that has the ordering marked.

Thank you! This thing keeps booting into the OS now. Is there a right amount of time to hold the power switch?
