I'll try removing the truncation then. Bear with me. In the meantime, notice that the truncated list does include one S3 item `SIO1(S3)`. I don't know if that's what we are looking for? FWIW, I have already tried `ZZZ` on this machine and it does succeed to hibernate, but upon wake up, it hangs when decompressing the memory image. I left it decompressing a ~50MB image for more than an hour and concluded it had got stuck. > 3.

I tried a Debian live USB stick, to see if Linux was able to sleep this box. It was able to. I don't know if that rules out the idea of a fixed-function button? -- Best Regards Edd Barrett https://www.theunixzoo.co.uk
