    Cannot Access BIOS Settings on a NUC5i5RYH

    Dalinian

      I have an Intel NUC5i5RYH (rebadged as a System76 Meerkat), which was delivered with BIOS v.0249, and booted from its M.2 SSD [1] into Ubuntu 15.04 in around 15 seconds. I was also able to access Intel Visual BIOS settings (on a Dell monitor via miniHDMI-HDMI cable) by pressing F2 at the BIOS logo boot screen.


      However, it has also exhibited the well-known 'Ubuntu Suspend > Dead NUC' problem, about which many threads exist here at communities.intel.com – and I've tried updating the BIOS to the (then latest) v.0350, but to no avail: Ubuntu Suspend still bricked my NUC with BIOS v.0350 installed. Only by disassembling the computer, disconnecting/reconnecting the CMOS battery, and reassembling the computer, was I able to get it to start up again.

       

      Now the computer takes two minutes to boot up, and I can no longer access Intel Visual BIOS settings by pressing F2 at either the BIOS logo boot screen or at the Power Button Menu: I just see a blank black screen on both a Dell monitor (miniHDMI-HDMI cable) and a Panasonic HDTV (miniDP-HDMI cable).

       

      I've tried downgrading to the original BIOS v.0249, and upgrading to BIOS v.0352, but to no avail: boot time is still two minutes, and I still cannot access Intel Visual BIOS settings by pressing F2 at either the BIOS logo boot screen or at the Power Button Menu. This is important, because a potential solution to the 'Ubuntu Suspend > Dead NUC' problem, posted by mikec_intel in...

      ...involves making changes in Intel Visual BIOS settings.

       

       

      So I'd be very grateful for any assistance in solving these two Intel NUC problems:

      (1) Restoring access to Intel Visual BIOS settings, via pressing F2 at either the BIOS logo boot screen or at the Power Button Menu

      (2) Eliminating the risk of bricking my NUC with each use of Ubuntu Suspend

       

      And if it could be restored to booting into Ubuntu in around 15 seconds, that would be champion.

       

      Thanks in advance for your attention and help.

       


      [1] Its M.2 SSD: "M.2 SATA: Samsung SSD 850 EVO M.2 250GB : PART 0 : Boot Drive"

       

      PS: I've sought help from System76 tech support, but sad to say they're about as useful as a chocolate teapot – so I'm hoping the Intel NUC community might be of some actual help in addressing these problems.

          After pondering the changes that have occurred since my Intel NUC5i5RYH (rebadged as a System76 Meerkat) arrived, I used trial-&-error testing to see which change might be responsible for causing the inability to access Intel Visual BIOS settings.

           

          Turns out the culprit is the miniDP-HDMI cable to Panasonic HDTV connection – with this cable unplugged, the BIOS logo boot screen shows up undistorted, the Power Button Menu appears much smaller, and pressing F2 at either of them now leads to Intel Visual BIOS settings showing up again (all on a Dell monitor, via a miniHDMI-HDMI cable).

           

          So I've been able to implement mikec_intel's potential solution to the 'Ubuntu Suspend > Dead NUC' problem, and only time will tell if this change + BIOS v.0352 actually eliminates the risk of Ubuntu Suspend bricking my NUC.

           

          Having regained access to Intel Visual BIOS settings, I tried switching 'Fast Boot' on, but it makes no discernible difference – the NUC still takes two minutes to boot up, from Power button press to the Ubuntu Unity desktop appearing, whether 'Fast Boot' is on or off. So any assistance in reducing this tediously slow boot time back to it's original c. 15 seconds would be much appreciated.
