Hi jeanfr: Thank you very much for contacting the Intel® NUC communities. We will more than glad to assist you with this matter.
In regard to your inquiry, the NUC has an option in the BIOS, which is “Power”, where you can select different light colors for different states. If you verify those settings you will see there are options to S0 state and also to S3 state, the fact that you get an orange light first and then the blue light could be because a combinations of those settings, S0 state is when the NUC is on, and S3 is when it goes to sleep or hibernation. If the NUC is working fine, what you can try is to get in the BIOS by pressing F2 while the NUC is powering on, and then press F9 to restore to defaults and finally F10 to save and exit. Or, you can also choose different light combination from within the BIOS as well. The orange light does not mean anything special, is just that you can choose the color of the light for the different states.
Any further questions, please let me know.
Hello jeanfr ,
I've updated NUC6i5SYH with bios 0063 and have not observed any change in power led color (i.e. it is blue all time during power on). Please follow the following paragraphs to fix your problem:
In the beginning set your bios to default settings.
- Enter bios pressing F2 during boot.
- Press F9 followed by "Y" to set defaults
- Press F10 ("Y") to save setting and exit.
Now recover your bios using Power Button Menu option: BIOS Recovery Update Instructions for Intel® NUC
- Download bios file SY0063.bios:Download BIOS Update [SYSKLi35.86A] and save it on USB stick formatted to FAT32
- Switch of your NUC and insert USB into slot.
- Press Power Switch and hold it depressed (about 3 sec) and release it when the Power Led changes its color from blue to amber. NUC will reboot into Power Button Menu.
- Press F4 to start the recovery process.
Hope this will help
I understand your message but Alberto R tells me that it is a normal operation.
So I do not see why I will have to make a recovery!
Who's right on the spot ??
Thank you for your feedback.
If the color change is normal I do not see the point of doing a recovery.
Besides that, I have no problem.
It is your NUC and you can do with it what you wish. In your post you have asked if it is normal that during boot, the Power Led changes color from blue to amber. I've answered that this is not normal. Also Alberto didn't say that this is normal. I don't know also how you can set your bios to cause led to work in such mode. I suspect that your bios is not updated correctly.
My post above is intended to give you help how to burn new bios version in right way.
The diode is orange when I press the button on
1 second later it turns blue and stays blue.
It would be necessary to see if other users have the same peculiarity.
Actually the bios maybe badly installed ....
Yes this information was helpful.
I did not reinstall the bios because you told me it was normal to have this operation.
This is normal?
if that is not normal I would like to know.
I tested this mostly out of curiosity. My NUC6i5SYH, with BIOS 63 installed, comes on blue. After a moment, it turns off. After another moment, it comes back on - and stays - solid blue. I check after both soft (shutdown) and hard (power button) power off operations. I also checked whether unplugging the NUC completely would make a difference. It did not; the process remained consistent.
That said, I do not believe that there is anything abnormal going on if it comes on amber and then goes to blue. I agree with Alberto; there are possible state transitions that could result in it momentarily being amber.
Bottom line, I wouldn't worry about it.
