    intermittent issue with infrared receiver...


    I have an Intel NUC (D54250WYK) running Windows 7 Pro 64-bit and has been working fine up until a few weeks ago, and the issue is intermittent making it difficult to troubleshoot.

    Every 2-3 times when the NUC wakes up, my remote control is no longer able to control the system. A simple reboot resolves the issue for a day or two, but then it comes back. One thing in particular that I found odd, is that the remote control is actually able to wake up the PC, but once Windows is up and running again it no longer accepts commands from the remote.

    I've completely removed the drivers and reinstalled but it hasn't corrected the issue. And none of my searches so far have yielded any solution to fix the problem.

    The Infrared receiver on the NUC is "Nuvoton Consumer Infrared (CIR) Driver for Windows 7 for Intel NUC"

    Hello and welcome Kwyjibo73 first up I think you should try these - I am not real sure of these little machines and am assuming the SSD is a normal one - forgive my ignorance.
    SFC /SCANNOW Command - System File Checker
    Disk Check < if necessary include the /f and /r in the command line as per Option2
    Run these in safe mode and the sfc often best run for two to three runs you can leave out the /r switch in ckdsk if you feel it not necessary
    NB SFC best run for about three scans

    MB I am not sure how one gets into safe mode but usually that is done by tapping F8 on power up

    Did you try fresh batteries?

    Thank you for the replies!

    ICIT2LOL: Thanks for the suggestions. Unfortunately neither the System File Checker (sfc) nor Check Disk (chkdsk) found any problems with the system.

    Itaregid: The issue isn't with the batteries or remote. It's a universal remote and continues to control my other devices without any problem, and it controls the HTPC once again after a reboot.

    The thing is, you cannot assume the receiver for this device is just as sensitive as your other devices. Perhaps the antenna is oriented a different way too, or the device is getting interference the other devices are not sensitive to. It does not hurt to try a fresh set of batteries if for no other reason than to eliminate them from the equation.

    I suppose it could even be the devices receiver too just a by the by how old is this device?

    The other thing that may sound a but simple but has the device been dropped exposed to high temps - anything that could have damaged it etc?

    I don't know if you feel about having a look inside the device to check for any signs of scorching on the board and even reseating the hard drive and RAM? From you saying intermittent also smacks of something maybe loose inside and that could be from something simple such as a dry joint on the board - I am not sure because I have never had one apart so I cannot say what the infrared receptor looks like - I do know that the devise that emits infrared actually looks like a black LED.

    A couple of vids to show you how to look note how different the hard drives can be

    Thanks again for both replies.

    Even though I was almost 100% positive the batteries in the remote were not at fault, I did change them. It did not improve the situation.

    To answer your questions...
    The NUC is 2 years old. No exposure to extreme temperatures, and has not been dropped. It's in a safe enough location to not have experienced any kind of physical damage.
    I'm also more than comfortable working in the innards of computers, so I did open it up and reseated the RAM and hard drive. I also looked over the motherboard and couldn't see any visible signs of issues or damage.

    While none of this rules out the potential for an actual hardware failure in the NUC, I'm still thinking this is an issue with Windows itself. I'm still hopeful to finding a solutions, but if not I may try reinstalling the OS.

    Yes mate it is I think simply because it is ok after a reboot - seems like something is "slipping out of gear" at some stage and why I asked you to run the sfc and chkdsk because it could have been just a simple file corruption that could have been fixed by those scans.

    Now it may even come down to a clean install too - by the by did you run any malware checks if not then run these please
    SUPERAntiSpyware | Remove Malware | Remove Spyware - AntiMalware, AntiSpyware, AntiAdware!
    Malwarebytes | Malwarebytes Anti-Malware Premium
    AdwCleaner Download
    ADW download from bleeping computer delete any rubbish found with the malware scans
    (NB If you are running Kaspersky as the main AV then it might need disabling it when trying ADW because it does not like it at times)

    For the reinstall do you have the activation key and/or install media (USB stick)? If you have the activation code then you can get the Windows ISO for whatever you are running and install form it but lets try those AV scans first. Plus there may even be a factory restore partition that you can use to get the device back to as it came out of the factory.

    Does a mouse or keyboard connected to the same USB port wake the computer? If so I don't see where a clean install is needed.

    You might try running sfc /scannow (note the space before the "/") and see if that resolves any issues.

    Try a restore point prior to the fault,
    Make a note of anything that will be changed/uninstalled
    If the restore works, then install/check the list and make the changes 1 by 1, to see if anything has corrupted the remotes ability to talk to your comp.
