Hi All,
I've had several users where after putting their laptops to sleep and bringing it back the alt ctrl del screen ceases to work. Without sleep it works just as it should or after plugging in a usb keyboard. Bootcamp drivers are up to date and I'm at a dead end. Any suggestions would be much appreciated.
Thanks,
Vinh
MacBook Pro with Retina display, Windows 7
1. What is the version of Windows?
2. What is the year/model of the Mac(s)?
3. There are known issues with Sleep in W7/W8+, including losing external device connectivity and wireless connectivity. USB hubs (including internal hubs) also have issues.
Hi LonerT.
Its Windows 7 and the models range from late 2013 to mid 2014.
Its not external devices but the internal keyboard itself.
Can you check Device Manager in Windows and look at any unknown devices or devices with yellow triangle and exclamation point?
You should also check if the correct BC Drivers are installed.
The correct bc drivers are installed. And in device manager everything looks good no triangles or errors.
Are these laptops plugged into power adapter when put in Sleep mode? What happens if instead of using a keyboard to wake the laptops, the power adapter is unplugged and plugged? Can you check Event Viewer for any events related to built-in keyboard and power?
W7 and W8+ have issues in correctly discovering devise when coming out from sleep. You should also check in Advanced Power options for events that can wake up the laptops.
The laptops aren't plugged in when put to sleep. It wakes up just fine and the trackpad works but the keyboard doesn't. I know theres a hardware test as i've seen it done at the apple store in the past. Would you happen to know how to get to the keyboard test they have during boot up. I will look at the events for both power settings.
Thank you
I am not aware of a keyboard-specific test. You can try Using Apple Hardware Test - Apple Support.
If the trackpad works, is this an external BT trackpad or the internal built-in one? Can you test the keyboard by pressing the Shift or Fn+Shift key after the machine comes out of sleep?
The internal keyboard and trackpad are tied to the same USB hub. The Keyboard driver is not being loaded up correctly.
Can you enable Remote Desktop on these Macs, and connect from another PC/Mac via a Remote Desktop connection and check the Device Manager after the designated Mac comes out of sleep?
it appears you may be correct on the keyboard issue as I saw an error in device manager but it goes away after a reboot. I will run a repair on the bootcamp drivers.
Thanks,
Vinh
Hey LonerT,
I reloaded the drivers and all but the issue is still happening. I even swapped the hard drive to a new machine but for some particular reason it was working for half the day and then decided to not work anymore. 😟 Any advice would be much appreciated.
Thanks,
1. What are the results of the Remote Desktop test?
2. Does a wired USB keyboard exhibit the same behavior?
3. I am not certain whether this is an internal keyboard or an external BT keyboard?
4. If it is an external wireless Keyboard, does the internal keyboard also show the same behavior?
Its the internal keyboard,
The test shows the same yellow exclamation point even after it was reinstalled and updated for the HID Keyboard driver. You can use a wired keyboard just fine.
Sorry about the duplicate question, I should have looked further back. 😟
After a normal Windows installation and BC drivers are installed. At this point there are no exclamation mark/yellow triangle devices. Now if you put the machine to sleep, it shows you a yellow triangle/exclamation mark. Is this set of events and state of the keyboard correct?
Hi, After waking up from sleep on bootcamp the alt ctrl del keys do not work. Any help would be much appreciated.
