<div dir="ltr"><div>Thanks for the idea, Kevin. I also was thinking it might be a graphics hardware problem. I will investigate, but pretty sure that this little SBC in NUC format has surface mount onboard graphics and will open it up to remind myself. The fact that the fan goes into overdrive when this happens made me think that it was also a SW issue with the handling of calls to the cpu/gpu getting out of hand? I'm fishing here :-)</div><div><br></div><div>Gavin </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, 1 Mar 2024 at 12:58, Kevin Shackleton <<a href="mailto:krshackleton@gmail.com">krshackleton@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Sounds to me like you need to re-seat bits in the box.

Every now and then, usually when trying to launch some full-screen video, the monitor blanks to just the backlight glow, the NUC fan speeds up and the keyboard is unresponsive. Because of the last factor, no amount of cntrl+BS, ctrl+alt+del, or trying to open a VT works. I have to do a hard reset. Any ideas of any other HW / keyboard options I can try, or even better, if there is a setting I need to look at to prevent this happening?</div><div><br></div><div>Thanks.</div><div><br></div><div>Gavin </div></div>
