[SOLVED] Sleep Wake failure in EFI (code:: 0xffffffff 0x0000001f)

[jynx26b]

Same issue here on 10.15.4! Everything works except no wake after sleep. When I reboot I get the error

Sleep Wake failure in EFI
Failure code:: 0xffffffff 0x0000001f

Any solutions? This has to common issue.
See Terminal pmset -g log below. Also config.plist attached. Thanks!!

I have the same problem like jynx26b. I deleted AppleALC and wake issue is gone.

Thank you for your response! I’ll try this today.

I tested also on the OpenCore BL and sleep is working OK with the same kext AppleALC + 10.15.4. Only on Clover + 10.15.4 sleep is broken from this kext.

I had this issue yesterday on one of my Dell Optiplex 7010 that was recently reinstalled. While the other Optiplex 7010 that was also reinstalled but doesn't have this issue, I spent a whole night scratching my head trying to figure
out what the heck was going on. Finally it came to my mind that the one has the issue was pre-formatted to APFS while the other one was pre-formatted to HPFS before installation. So I installed the machine again with its disk formatted to HPFS. Then the issue disappeared magically without any other changes.

But can you confirm that the two 7010s has the same BIOS setting? and both have Advanced Bios Option> √ Enable Legacy Option ROMs (enabled) ?

The option is enabled in my BIOS setup.
And both machines have exact same bios settings.

Go to System Preferences => Energy Saver,
uncheck "Put hard disks to sleep when possible"
if you have more than one disks.

I hope it will help me, I have the same issue.
