NUC is power off with a caution message.

[AJoy]

Hi,

I am using an Intel NUC (Model number: DN2820FYK) for past couple of years. Now I am unable to use this because as I power on the system, it shows a message "Caution : Using other than 12V DC adaptor may cause component damage and unstable system performance" and automatically gets power off. I am sure that I was using the same charger till date from the beginning and it was working fine so far. So, please help me with the possible chances of this issues and remedies.

Thanks in advance.

It sounds to me like your power supply is starting to fail. Replacement supplies can be purchased from many suppliers. I have even seen them listed (for less than US$10) on Amazon. Some even list themselves as being replacements for NUCs, so you can search for them using your NUC model.

Hope this helps,
