Olá prezados boa tarde,

Tenho um nuc 5i3ryb e não liga. Quando tento ligar a luz do led pisca 3 vezes e não liga. O que pode ser?

Three flashes is an indication that the memory could not be initialized. This could be caused by a failure in the processor's memory controllers or in components on the board itself, but the most common cause is a failure in the memory SO-DIMMs. Unfortunately, the only way to tell is to try using alternative SO-DIMM(s). If alternative SO-DIMM(s) do not work, the NUC will need to be replaced as processor and board failures are unrepairable (the processor is considered to be permanently soldered to the motherboard).

People often ask why a system can run for a very long time and then suddenly have memory issues. The issue is electrical noise. Every component in a system generates some amount of noise. The chassis is designed to eliminate some of this noise (and stop some noise generated within the NUC getting out) and the memory buses on the board contain circuitry to help dampen noise (and prevent issues like signal reflection), but if noise levels reach certain thresholds, the processor and/or SO-DIMM(s) will not be able to distinguish noise from data. This can cause bus lockups to occur as well as a host of possible recoverable and nonrecoverable data errors. Why this will happen in older equipment is because the age of the components plays a role: simply put, as the components age, they produce more noise.

Hope this helps,

…S

Prezado n_scott_pearson boa tarde!

Muito obrigado pela resolução. Ajudou muito. Fiz alguns testes com outras memórias e não funcionou. Este fato comprova sua tese. 

 

 

Grato,

Unfortunately, this means that your NUC will need to be replaced. Provided you purchased your NUC new and through an authorized dealer, your NUC came with a 3-year warranty. If you are still within this period (you can check that here: Determine if Your Product Is Still Under Warranty), then you can request a replacement via Intel's RMA process.

In order to request a replacement, you need to directly contact Intel Customer Support to initiate the RMA process (you cannot do this through the forums). Here are pages where you can lookup contact information, including local/country phone numbers, by geography:

You can use the online forms service or email, but I actually recommend calling them directly. The above links provide local or toll-free numbers in most countries and support most local languages. You could also use the chat service (start here: Intel Customer Support Chat), but understand that this service is offered in English only and is subject to the normal (9:00-5:00 M-F) office hours in the Pacific (UTC-8) time zone.

Hope this helps,

Hello @wdias7

Thank you for posting on the Intel® communities. Informamos que só posso dar suporte a você no idioma inglês. Eu tenho usado uma ferramenta de tradução web para traduzir esta resposta, portanto, pode haver alguma tradução impreciso.


We hope that the assistance provided by the community has been helpful.

Also, we would like to inform you that due to the Intel® NUCs based on the "NUC5i3RYB" board have been discontinued, Intel Customer Service no longer supports inquiries for it, but perhaps fellow community members have the knowledge to jump in and help. You may also find the Discontinued Products website helpful to address your request. Thank you for your understanding.

Please keep in mind that this thread will no longer be monitored by Intel.


Best regards,

Andrew G.
