Z890/270K Plus sleep issues
MSI z890 mag tomahawk wifi board
270K plus cpu
4x crucial CP2K16G64C32U5B 16gb ddr5 6400 MT/s
Installed to sata ssd
Sleep function appears to just blank monitor. Kill-a-watt meter shows idle power drop from ~30W to 15W, fans continue spinning.
Same test using ubuntu 26.04 and KDE neon (kernel 6.17.x) drops power to 0-2w (s3), fans stop, etc. Proper s3 sleep.
Suggestions on how to proceed to get tux to sleep properly?
