Merry Christmas Maldon! meanwhile got further. According to the linked thread, I checked the "block sleep" option in bios, what seems to be paradox - but it works. So shutdown works now and the computer goes to something like a "sleep-light". Display and keyboard are off, but the fan ist still on, on a very low level. Battery drain is to high. Pmset stats give me also wakes but no sleep counts. https://osxlatitude.com/forums/topic/20324-latitude-5310-kp-on-sleep-sleep-wake-failure-in-efi/ the solution there, seems to be the unlock of cgf using setup_var.efi. Though I wrote a few hardware tutorials on insanely mac, back in the early years, this is digging to deep for me. I am not experienced enough with this, and afraid of dmaging my device. Could you help me with this?

Sleep still doesn´t work. Won´t there be more support after the donation, or is it just a question of time? I have no problems to wait - just need to be informed

Now this gives me a working shutdown <dict> <key>Base</key> <string></string> <key>BaseSkip</key> <integer>0</integer> <key>Comment</key> <string>_PTS to ZPTS(1,N)</string> <key>Count</key> <integer>0</integer> <key>Enabled</key> <true/> <key>Find</key> <data>X1BUUwE=</data> <key>Limit</key> <integer>0</integer> <key>Mask</key> <data></data> <key>OemTableId</key> <data></data> <key>Replace</key> <data>WlBUUwE=</data> <key>ReplaceMask</key> <data></data> <key>Skip</key> <integer>0</integer> <key>TableLength</key> <integer>0</integer> <key>TableSignature</key> <data></data> </dict> Now it goes goes proper to sleep, but wake up results first in turning on backlight, followed by a reboot. Added once more kill pwr. Didn´t help....

Thanks for the suggestion Maldon! I applied this patch, but still the same: Display sleep works if I wake it straight after backlight gets dark. 10 seconds later nothing works. no sleep. no shutdown. by the way......my donation was the one with nermin.....

I checked the USB-mapping once more and compared it with your guide. Attached is a pic of corrected version, but still no luck. Bildschirmfoto 2024-12-17 um 18.26.28.zip

Yes I do. opencore for KabylLake notebook. Maybe this helps: Sleep works randomly once. Shutdown never. Screen turns black, backlight and fan still on. The crazy thing is, that the old system worked flawless with Big Sur until I installed Sonoma on the other volume. Since that it stopped workin as well. After I checked the bios settings a few times and even updated the bios from 1.26 to 1.38. My suspicion is a possible hardware failure. I tried a few solutions, including GPRW. USB should be mapped properly. Before I replace the ram, I wanted you to check the files to exclude this option. Meanwhile I removed BigSur and installed Sequoia instead, next to Sonoma. Problem still persists with both OS. Edit: it reports following message Sleep Wake failure in EFI Failure code:: 0x00000000 0x0000001f

Hi Maldon, I was using your perfect DSDT on this machine till updating bios and system to Sonoma. Got everything working except sleep and proper shutdown. Can I send you a dropbox link to download the Send Me file? Cheers from Austria
