Boot Camp Win 10 wake problems on Macbook Pro

The solution that worked for me is outlined here: http://superuser.com/a/935891/75790

In essence, the Startup Disk must be specified in both Bootcamp and Mac OSX. I found that in my case, the Startup Disk was specified in Bootcamp but not in Mac OSX. Once I picked a startup disk in Mac OSX, my Windows 10 was able to wake up from sleep.

I spoke to soon. The technique I outlined didn't help. My MBP is again not able to wake up from sleep. :-(

The outlined method may have worked for 2011 Macs (even though it makes no difference what your startup disk is set to, to enable sleep/wake). I suggest you try a SMC Reset/NVRAM Reset to see if it helps.

Sleep/Wake is driven by events which the hardware/firmware propagate to the OS. If OS ignores them, there is not much that can be done. W7 (and W8) Wake/Sleep are very buggy with various vendors implementing their own solutions on PCs. You can check the Windows Event Viewer to see if the Windows Kernel acknowledges such events or not. W10 is much better, but may not be 100% perfect. If OS X wakes/sleeps properly on the same hardware, the issue is squarely at the OS door which is currently controlling the Mac, Windows in this case.

Hi hzonhzon,

I reinstalled ATI Drivers from the link, survived for one day and the problem arose again. However, I can wake up my MacBook Pro after going to sleep. I also did an SMC and a PRAM reset. The computer goes to sleep after about an hour, which used to go to sleep between 20 - 50 minutes. The startup disk has been set to "Mac OSX" in both partitions.

Here's a screenshot of advanced power options:

Is this an issue with Windows 10?

MacBook Pro (Late 2011) running Mac OS 10.11.4

Looks like it is an issue Windows 10 : http://answers.microsoft.com/en-us/windows/forum/windows_10-power/windows-10-goe s-into-sleep-mode-automatically/ce1caf3c…

I'm sorry. That fix was temporary. Having the same issue again

After successfully installing Windows 10 on my new MacBook Pro I had the wake-up problem as well.

For me personally the best explanation of the issue was in this post: http://www.macwindows.com/Thunderbolt-Limitations-of-Mac-running-Windows-and-get ting-around-them.html

After I disconnected the thunderbolt-ethernet interface and the external USB drive, the problem was gone.

While there might be several causes for the problem, at least this one was spot on in my situation. Apparently Windows can only recognise thunderbolt interfaces during startup and not after a wake-up. I've also noticed that the Mac gets warm in sleep mode (with thunderbolt interface connected), which seems strange. Since I do need my ethernet connection, the only workaround seems to disable sleep mode completely.

Wow setting the same Startup Disk (to Bootcamp Win10) in both OSX and Win10 fixed my Win10 sleep but cannot wake (black screen) issue. Now that I recall this probably started when I changed the default startup disk in one place but didn't set the same in the other.

I have mid 2015 MBP with Radeon M370X.

After trying the fix above then testing over the past day I haven't had any sleep-wake issue yet. Tried manually putting Win10 to sleep then wake, also closing the lid then wake, also leaving it overnight before waking all had no issues. Fingers crossed that fixed it.
