PRO Z690-A DDR4 Sleep issue

[pdaen0fad0270]

My PC has a strange issue of sleep function with PRO Z690-A (maybe)
First, the PC has no problem wake up from remote (wakeup on LAN) in any whatever situations (This is good)
However, if sleep for a long time, if I push the physical power button of the case, it won't wake up ( but, I can still wake it up from remote, like iPhone)
If sleep for a shorter time, it is ok.

I use Windows 11. Powerbutton is configured to "Sleep".
The case is Lian Li Lancool II MESH Type C RGB Tempered Glass ATX Mid-Tower Computer Case

Now, I have to keep my iPhone to wake up my PC everyday.

Did I do something wrong?
Thank you very much.

did you enable XMP? early z690 bios had some issues waking up from sleep when you enable XMP.
maybe try clear CMOS or update BIOS

Yeah, lots of sleep-related bugs in the earlier BIOS versions. So make sure you are on a new version.

Yeah. Problem solved. updated BIOS to the most recent version.

Did you use M flash to flash the Bios? M flash sees my usb drive but are unable to see any files when i want to flash the bios. Tried a few different usb sticks, from 4-64 gb all formatted to fat32

Make sure you have downloaded the proper file for your exact motherboard (such as DDR4 vs DDR5) and have unzipped the file after the download.

For M-FLASH, there is no special procedure necessary. Just use an USB stick (NTFS format is ok), extract the correct BIOS file on there, and M-FLASH should show it, if the model name matches.

I used a super cheap USB key and front usb socket of the case. I did format the USB key using windows default quick format (did not change any options).
