Windows 10 / Bootcamp 6 fails to put laptop to sleep / hibernate (Mac Book Air Early 2015)

Hi,

After installation of Windows 10 my Mac Book Air (11" Early 2015) was working perfectly. However after Bootcamp auto-update a new problem started to occur: once for 1-2 attempts to put laptop to sleep mode (for example by closing the cover, or by the command to put it to sleep, or if it is configured to enter sleep mode after certain time) the laptop somehow hangs (the screen is blank, however one can hear that the fan is still working). This operation is irreversible (the only option is to turn power off by pressing power buton for several seconds).

Any idea what driver may be casuing this? I have found threat about powering off (Windows 10 Fails To Shut Down my Late 2013 Mac Pro), however my laptop does not have AMD Fire Pro Control Center...

Best,

MacBook Air, OS X Yosemite (10.10.3), Windows 10, Windows 8.1, Windows 8

Did the Windows Update create a System Restore point? Can you check Windows Update History to see which updates were applied?

Can you list the KB numbers of the last Windows Update? If you recall the date when it stopped working, look at only those units. As s test, is it possible to Repair Windows and rollback to the previous System State, if a System Restore point does exist?

Hi,

I have (starting from the newest)

KB3081455

KB3081448 (on the same day the Bootcamp update was installed)

KB3081449

KB3081452

KB3081441

KB3081444

KB3081438

KB3087916

KB3081436

KB3074686

KB3074678

KB3081424

It has to be one of the first 4 from the above list (after fifth from the list the system was still stable).

Best,

I put the links. Please check if I have any typos.

My suspicion is 3081448, because of this.

Acpi.sys

10.0.10240.16397

It is an ACPI Update which on a Mac is bad idea. Can you find the BC/W10 ACPI driver and update using that after you create a System Restore point, so it can be tested and rolled back, if necessary? That date is 22 Jul 2015, which is bit strange. Why provide it now, if it has been out since July?

Indeed I have acpi.sys in version 10.0.10240.16397, however the size of the file is different (mine is 565,088). I have another Mac, which does not have KB3081448 and have the same acpi.sys file, so I guess that it is being installed by something else than this update.

Does the other Mac have any sleep issues? I suggest we need to look for files from each update. If you have the ability, can you roll back to the last System Restore point (assuming they are enabled) and test.

Hi, the other works fine... I have downloaded BootCamp 6 drivers and manually reinstalled the full package - now the problem disappeared (I can put Mac to sleep and wake it - I have tried it several times and it worked). So maybe indeed it was something which was done by Windows Update, however reinstallation of BootCamp drivers seem to have solved it.

1. Can you post the current version of the ACPI driver for completeness?

2. Create a System Restore point, which you can roll back to, if necessary.

3. You may want to prune Driver updates from Windows Update to be a bit safe.

Hi,

After more tests: reinstalling Bootcamp drivers hadn't solved the problem. For some time the computer was allowing to be put into sleep from-time to time, but for most of the cases it "hanged" after closing the cover. I have also observerd that even putting it in hibernation from Windows was not successful (the computer hanged and one could hear that the fan inside was still on while the screen went dark). Of course on MacOSX it was working properly.

The thing I did recently:

- I have UNinstalled all Apple driver packages from Control Panel / Add Remove Programs

- Then I have installed only touchpad, keyboard and bluetooh (and I have used Bootcamp 5 as the source)

Since then - the computer works perfectly - it didn't hang even once.

The conclusion is that the problem was: or Bootcmp 6 drivers (I don't know which), or the fact that initially Bootcamp 5 drivers were installed and afterwared they were upgraded (by Apple Updater) to version 6 - I have discovered that in Control Panel ver 5 drivers were still present along with ver 6 drivers.

Best,

Hello,

After some more experiments:

I had to install full BC6, because sound and camera was not working - after new instalation the problem of "hanging" reappeared immediatelly
I tried to remove all BC6 packages except bluetooth, keybord, sound, camera and track pad - the problem was still there
I have removed all packages of BC6 and installed keyboard, bluetooth and trackpad from BC5 and sound + camera from BC6 - problem disappeared

The problem is definatelly in BC6 drivers, maybe in bluetooth?

Best,

hcsradek

Any device driver which supports PnP may be responsible for such behavior. Thunderbolt had this issue for a long time. SD Cards, USB, Firewire all show similar behavior across various versions.
