nuc6i5syk always warm even it is off

[ycili]

hello everyone, I bought a second hand nuc6i5syk it works fine. noticed that it is always warm even it is off. After checking its bios I found the reason. It is usb charging status for portable devices, when I turn it "off" it stays cool when it is off but when it is "charging in s3/s4/s5" my nuc keeps being warm even it is off. It is already updated to the latest drivers and bios firmware. What I want to know is if this is an issue to be corrected by intel or not. Any help is muchly appreciated.

Hello levocil ,

Do you have connected some device to the orange USB port at front? I've have NUC6i5SYH, and is is not worm while is OFF, although the charging function is enabled. So, if you have not connected any device to this port, probably is some short circuit in this port. I suggest that you should check if this port is working at all. If is not working, better disable it in bios.

Just to be clear - You bought this NUC second-hand. Only the original purchaser is entitled to warranty coverage. Bottom line, regardless of anything else, there is no "issue for Intel to correct". For more information, you can consult the International warranty here: https://www.intel.com/content/dam/support/us/en/documents//boardsandkits/H44948_Warranty_NUC_3YR_Intl.pdf Intel NUC 3-Year International Warranty and the Australian warranty here: https://www.intel.com/content/dam/support/us/en/documents/motherboards/desktop/sb/h44946001_nuc_australian_3year.pdf Intel NUC 3-Year Australian Warranty.

Regarding your issue, if you do not like it warm, you can disable USB charging in S3/S4/S5 and avoid the situation.

Hope this helps,

Hello Leon, thank you very much for your kind reply, all usb ports are operating normally, I just turned it off in bios. great probably a short circuit causing this as you said. Anyway I can live with that . Have a good day.

I did not intend to ask you to turn OFF all your USB ports. In case that you want to use your USB as a USB host port (i.e. The host port initiates all communication on the bus and supplies 5VDC), you should leave this port switch ON. Otherwise, if for example you will connect device to this port, such as external drive, mouse or keyboard, it will not function. My intention was to check if the problematic port (with orange color) has not a short circuit. Any way, leave the other 3 USB port ON in order to be able using them as a host ports.
