NUC beep codes for memory or other components

[jrc01]

Having an issue with an NUC7i5bnk that I bought used. After couple months using it I turned it off before going to bed like I always did and next day it would not turn on. Was giving me a 3 beep code, I bought a new cmos battery and nothing changed so I got brand new ram memory and still does the 3 beep code. I think is something else but I cannot pinpoint what is it. If anyone can help me with this I would really appreciate it.

What exactly is the beep code that you are seeing/hearing? Does the beep code repeat or play only once?

Hi, thanks for the reply. Does 3 beeps and It repeats around 4 -5 times and it restarts. I’m worried is a bad bios not booting because I just installed new ram and the cmos battery is new.

What kind of beeps? Long? Short?

You bought a replacement battery. Did you verify that the replacement battery is keyed (red and black) the same as the old one? [Aside: if it's wrong, you can swap the pins in the connector.]

I don’t remember well. I think it does not have the same colors but is a two pin connnector that fitted the same. Could not find a battery just like the original.

[n_scott_pearson]

The fact that it has the same connector means absolutely nothing. You have to make sure that the black and red pins are in the same position in the connector as was the previous battery. There is a good chance of them being backwards as Dell does it the opposite way and they have many more system-level products that Intel (a component supplier) and hence more people are selling then keyed incorrectly for the NUCs.

Well, it has the same colors but after inspection, is connected opposite of what the old battery is wired. I installed again the old battery and tried to start and no boot, so it might be the battery. I need to find a place that can sell the right one, eBay got me with this reversed one. If anyone knows of a good place that caters to this nucs let me know. I will get the old battery later and see if I can find a local place here.

Hold on, you don't need to get another. Instead, you can pull the pins from the connector and put them back in the other way. The pins are held in by a small tab that you can (carefully!) lift up to release the pins. Sticking the pins back in, the tabs will lock them back in. To lift up the tabs, i use the blade of an exacto knife. This way, you don't lift them too high.

Of course, three hands are required:  one for the xacto knife, one to hold the connector, and one for the magnifier.

Only need that magnifier if it's us old fogies doing it.    ;^)

Thanks for the replies, greatly appreciated. I did as you explained, changed the wires and connected, still having issues. I have done pin reset, battery disconnected and nothing. Tried even to press the button after 3 seconds when starting up method and it just turns off and restart again doing the 3 beeps with 3 times blinking blue light 4 - 5 times, sometimes more but then it restarts. I am really tired of working with this machine that gives me so much trouble. Don't know what else I can do

Hhmmm... 

I don't think getting into the Power Button Menu is going to help you. I think you need to try doing some component elimination. Start by removing the M.2 SSD and, if tall chassis, disconnecting the SATA power and data cables going to the drive bay. Power on like this and see if it still goes into failure mode.

If it still fails, leave those components disconnected and try powering on with just one of the SODIMMs installed. There are four configurations you should try, powering on with SODIMM1 in Slot1, SODIMM1 in Slot2, SODIMM2 in Slot1, SODIMM2 in Slot2.

Let me know the results,

Thanks! I did the last steps you recommended and still having issues. At this point I consider this machine deadline and no possible recovery unless I take it to a shop that will come to a cost around the same that the PC. I’ll leave it there for now until I can get a tech with better tools to inspect. Thanks for the help guys.
