Quite a few people faced issues with the BIOS version 33 on their Skylake NUCs. Eventually version 33 was even pulled from Intel’s download center. There were reports of NUCs even frying themselves after 33 update. Now Intel has released the Skylake NUC BIOS version 36 and in the release notes they state (among other things):
- Improved reliability of the heatsink fan.
- Fixed an issue that would cause the fan to stop spinning when user manually modify duty cycle increment to maximum value may cause fan stop spin, modified divisor from 256 to 255.
- Fixed issue where the LED on an m.2 SSD would not function.
- Fixed issue where an m.2 would not show device information in the SATA page in the BIOS.
- Improved EFI Capsule algorithm.
- Changed power button recovery beep count from 1 to 3.
- Improved LED blink code.
I’ve just updated mine to version 36 and the system seems to be running ok. Though I did not observe any issues before either, but maybe my use was not stressing the NUC enough. If you’re running BIOS version 33 on your Skylake NUC, I’d suggest an upgrade… Do note that it’s recommended practise to reset the BIOS settings to defaults after a BIOS upgrade. To do this, enter BIOS normally (press F2) and then reset the defaults by pressing F9.
Have your say
I don’t have any long term experience yet running this Skylake NUC BIOS version 36, but I’m sure we’ll hear soon enough plenty of user stories in the Intel NUC community and hopefully here too. If you’re running the new version 0036 in your NUC, I’d be happy to hear your experiences in the comments section down below!
