Bounc1ngbanker Posted January 7, 2018 Share Posted January 7, 2018 Hello. Does anyone have insight into wake up from sleep and graphics card initialisation? Have recently installed OS-X Sierra on a Dell T5610. IT works just fine apart from 'sleep'. When I select 'sleep' the screens immediately go black. About 20 seconds later the machine goes into 'deep sleep' mode with the fans off. It wakes up when I move the mouse or hit a key. It doesn't appear to have crashed: However, the screen stays black. Yesterday, the machine was rebooting but then I realised that I needed to remove NullCPUPowerManagement.kext. Once that was removed, the crashes stopped happening - however - the screen stays black on wake up. If I move the mouse before the machine actually enters 'deep sleep' then the screens come back on just fine. I have not managed to find much information about the darkwake=x flag in clover apart from this: darkwake=0 -darkwake=1 HIDTickleEarlydarkwake=2 HIDTickleLatedarkwake=3 HIDTickleNonedarkwake=4 IgnoreDiskIOInDark (believed removed)darkwake=8 IgnoreDiskIOAlways (believed removed) darkwake=10 HIDTickleLate | IgnoreDiskIOAlways HIDTickleEarly hid tickle before gfx suppressionHIDTickleLate hid tickle after gfx suppressionHIDTickleNone hid tickle is not postedIgnoreDiskIOInDark * ignore disk idle in DWIgnoreDiskIOAlways * always ignore disk idleAlarmIsDark 0x100GraphicsPowerState1 0x200AudioNotSuppressed 0x400 I tried darkwake=0 with no effect. I tried darkwake=1 and the system didn't enter 'deep sleep' at all. Running this command in the terminal: pmset -g log Gives me the below. I don't see anything particularly unpleasant there - does anyone know if this is normal?

Bounc1ngbanker Posted January 7, 2018 Author Share Posted January 7, 2018 Amendment. Darkwake = 1 and the system did enter 'deep sleep' after about 35 seconds of 'screen off'. And it woke up and gave me a display too. But no mouse/keyboard response and no mouse pointer visible. Digging around a bit more, I'm getting the impression that the system DSDT still isn't right. I read that the USB devices may need a _DSM method to inject power related information in this post: http://www.insanelymac.com/forum/topic/311144-wake-up-from-sleep-and-usb-issues-10112/ Does anyone have any pointers about that?

Bounc1ngbanker Posted January 9, 2018 Author Share Posted January 9, 2018 Seriously. No replies? Bit disappointed that I've had hardly a single response to anything on this forum. Not what I expected... 1 Link to comment https://www.insanelymac.com/forum/topic/331361-screen-stays-black-after-wake-up-from-sleep/#findComment-2564987 Share on other sites More sharing options...
