I am looking for people with a Skylake build with a flashing power LED in sleep state. Do you have a flashing power LED, then please comment here what motherboard/processor/GPU you have. Please also link to your ACPI files.
Thanks!

Great people share their wisdom without asking for anything in return…

I don’t have a Skylake box, yet what I’ve seen in the past is that Asus boards by default use a flashing led in sleep, ASRock boards give you a choice in bios settings, and Gigabyte boards don’t flash or give you a choice…
Thanks. We can also enable/disable the flashing LED with help of ACPI. My father said to look at his DSDT for Asus P5K-PRO with references to the Intel datasheet, but I don’t happen to have his old DSDT’s handy.
I also known that during the installation of the Broadwell-E processors, the power LED flashed in the installer, and sleep/wake worked. No black screen. Afterwards I flashed the BIOS and the power LED no longer flashed. Sleep/wake still worked though, but I like to check if this is somehow related to wake issues where people end up with a black screen.
I have a flashing led but with Haswell-E CPU, MB Asus X99-S. Sleep doesn’t work correctly though, it goes to sleep but returns from it by itself after a short period of time, sometimes it returns okay and sometimes it restarts.
It should work with Haswell-E setups. Not with Skylake, where people are stuck with a black sleep after it tries to wake up.
Yes, I read about other working builds with the same CPU, couldn’t figure out what is wrong with mine yet, still trying though 🙂

Thanks. And just to be absolutely sure. Your power LED flashed when your ZenBook sleeps? Would you mind trying to locate the code in the _WAK method that enables the power LED?
Yes it flashes when it sleeps and the strange thing is that sometimes it wakes up from sleep and sometimes it doesn’t. I tried to find a pattern but I couldn’t. I also tried to change the hibernate mode (0 3, 25, 29), but that also didn’t help.
Probably you are looking for this code (?):
Method (_WAK, 1, NotSerialized) // _WAK: Wake
{
RWAK (Arg0)
\_SB.PCI0.NWAK (Arg0)
\_SB.PCI0.LPCB.SWAK (Arg0)
OEMW (Arg0)
Return (WAKP) /* \WAKP */
}
I have an older setup (Sandy Bridge), with an MSI board that flashes the LED in Windows, do you want that one? (I’m not allowed to mess too much around with it, as it is my girlfriends system, but I should be able to dump the tables if you want them).
My own system (Skylake), based on a Gigabyte board does not flash the LED in any OS (macOS, Windows, and Linux Mint).
Hey piker 🙂
If you need, i have a flashing led with ux301la (haswell i7-4558u)…
sleep, hibernate, etc… Work perfect here, if you need sth, comment:-) cheers:-)
I have an Asus Z170 Pro Gaming/i7 6700K with flashing power-led during sleep.
at wake-up my HD led starts flashing at a constant rate of +/-3 times/sec, after a few seconds the machine reboots.
Method (_WAK, 1, NotSerialized) // _WAK: Wake
{
If (LOr (LLess (Arg0, One), LGreater (Arg0, 0x05)))
{
Store (0x03, Arg0)
}
RWAK (Arg0)
\_SB.PCI0.NWAK (Arg0)
\_SB.PCI0.LPCB.SWAK (Arg0)
\_SB.PCI0.LPCB.SIO1.SIOW (Arg0)
\_SB.PCI0.LPCB.SIO1.SIOH ()
Return (WAKP) /* \WAKP */
}

FYI. in clover I still use:
– rename GFX0 to IGPU (for SaSSdt)
– and injection of IntelGFX Properties. (AAPL,GfxYTile)
Thanks. I compared your DSDT with mine and what I see is that method SPTS does a Store (One, AES3) for sleep and method SWAK does a Store (Zero, AES3) and I have neither of them. Can you please comment them out and recompile the DSDT to see if this is the on-off switch for the power LED?
Hi Pike,
I commented out both Store(x , AES3) lines, but my powerLed is still blinking in sleep.
Ok. Thanks. So AES3 is not it. Did you try to comment out any other lines in Method (_PTS)?
Commenting out: \_SB.PCI0.LPCB.SPTS (Arg0) (from _PTS) leaves the powerLed ON during sleep.
On as in solid/no flashing LED?
only commenting out : Store (One, SLPE) (from SPTS) also leaves the PowerLed on during Sleep. (offcourse with all lines from _PTS uncommented.)
So SLPE most be what you’re looking for.
Indeed ON as in No flashing.

Here you go.
At this link you can download the EFI folder (ACPI table in CLOVER\ACPI\origin) with config.plist, kext etc… plus an IOReg dump, if needed.

Confirmed flashing led on sleep and black screen on wake-up
I’ll be home late, but this is definitely something I will look at.
No flashing LED, but do get a C6 code which is supposed to mean – OEM BDS initialization the motherboard when trying to wake from sleep.
Here: GA-Z170X-UG and Skylake i7-6700 with Powercolor AMD Rx480, no blinking (red) during sleep. Still ACPI tables needed?
No thanks. Gigabyte motherboards do not enable the blinking power LED, but Asus motherboards does, and I am trying to port it to (my) Gigabyte motherboards. How else can we see that the PC sleep?
Easy: all the fans (GPU+CPU) are off, and the energy at the electrical plug goes down significantly…
In my case I have a lighted keyboard during sleep staying on..also with flashing led
one of this should be off in my case
I would say the keyboard.
ASUS Z170P D3, Skylake 6700K, Powercolor AMD R9 380. Flashing HD Power LED. Sleep/Wake successful. ACPI Tables etc.: https://dl.dropboxusercontent.com/u/77984956/Arquivo%20Comprimido.zip
Thank you. Another one to look at. Hopefully I can find something…
Edit: You DSDT is seriously broken!
What can I do? Thank´s!
@Pike, any news about the gigabite flashing led? I have a skylake i7 h170n wifi machine, and I really would like to have a blinking led thing during sleep.
Lenovo 300-17ISK(i5 6200U with HD520) have flashing led in sleep mode.
