Lenovo X270 - Sleep/Wake

[iPwnJ00]

Hi all,

I've successfully installed Sierra 10.12.6 on my X270 with a lot of DSDT-edits and a few kexts.

CPU: i7-6600U
RAM: 16GB x DDR4
GFX: Intel HD520

Everything seems to work (WLAN swapped with DW1560) except for sleep/waking.

So, as I understand, there is a half-sleep and full sleep.

When the laptop is in half sleep (before it's actually gone to sleep), I can still wake the laptop by pressing any key, opening the lid or pressing the power button.

However, when the laptop is in full sleep, the power button will be blinking (breathing animation) and nothing will work:

1. The power button does not respond - but the fans start spinning
2. The keyboard does not respond
3. The trackpad does not respond
4. If I close the lid and open the lid again, the power button stops the animation (stays solid) but the screen is still black - but the fans start spinning

I've tried a lot of things and reading threads but I can't seem to work out what the issue is. It's also quite hard to debug because the only way to get my system back is by turning it off and back on again so I can't get any ACPI debug logs.

Does anyone have any idea what the issue is?

Your kextcache output shows kexts not installed correctly. Read post #2 of the guide:
https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

Use OsxAptioFixDrv-64.efi not OsxAptioFix2Drv-64.efi.

Make sure hibernation is disabled. See guide: https://www.tonymacx86.com/threads/guide-native-power-management-for-laptops.232994/

Your USB configuration is wrong. Read here: https://www.tonymacx86.com/threads/guide-creating-a-custom-ssdt-for-usbinjectall-kext.211311/

Backlight control is not implemented correctly. Read here: https://www.tonymacx86.com/threads/...rol-using-applebacklightinjector-kext.232976/

Hey @RehabMan, thanks for responding.

Your kextcache output shows kexts not installed correctly.

The kexts that are showing in the output are installed by 3rd party hardware that I use; for example, a USB 4G modem. They are unrelated to the system.

Use OsxAptioFixDrv-64.efi not OsxAptioFix2Drv-64.efi.

Just done that, no changes seen.

Your USB configuration is wrong.

I followed that; what exactly did I do wrong?

Backlight control exists right now in Display prefspane. Does it make any difference to implement it using AppleBacklightInjector?

I see you still didn't read post #2 of the guide: https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

Clearly, you did it incorrectly.

Your ioreg shows no SSxx ports on XHC.
Yet you have HSxx ports marked UsbConnector=3 which implies you have USB3 ports.
For each HSxx port with UsbConnector=3 there must be a corresponding SSxx port with UsbConnector=3.

Yes.
Follow the guide.
