Q: Power button and keyboard combo no longer do anything.

Using a 2012 15" Retina MacBook Pro with an external 27" TBD and wired full size Apple Keyboard.

 

Since the upgrade to Yosemite (from Mavericks), I've been lucky enough to not get the wi-fi issues, however I can no longer sleep, shut down or restart the machine from either the power button or by pressing ctrl-eject.

 

With 10.8, pressing the power button would ask me what I wanted to do. On 10.9 Mavericks, the machine would go into sleep and on 10.10 it does nothing, but if I hold it too long, it cuts the power to the machine!

 

The external keyboard worked all the way up until 10.10, now pressing ctrl-eject also does nothing. The only way to send my machine to sleep is to close the lid or select "Sleep" from the "Apple" menu.

 

Here's the weird thing, a couple of days ago, pressing the power button displayed the sleep / restart / shut down dialog, but today it's back to doing nothing.

 

Anyone else, any ideas?

MacBook Pro (Retina, Mid 2012), OS X Yosemite (10.10.1)

Hi Barney,

Thanks for responding. That's the problem, pressing or holding the power button for a short period of time does nothing under Yosemite. However, you hold it too long and it kills the power.

 

Also worth nothing is that the keyboard combo (which has worked since 10.8) no longer worked.

 

However, I have solved this issue now, after reading on the forums that many people's issues were solved by zapping the PRAM (like we used to do in the classic days) and just tried it... Bingo, now I get the sleep / shutdown / restart dialog from both the power button and the keyboard combo.

 

It seems that the Yosemite installer screws with the PRAM on machines.

    You have to hold the power button for ~ 1.5 seconds to get sleep, 2.5 seconds for dialog, and longer for force shutdown.

    Spoke far too soon. Today the Keyboard Combo no longer works, but at least for the moment the Power Button is displaying the sleep / restart / shutdown dialog.

    No, that's not the problem with Yosemite. It is apparently the problem with your Mac. Apparently, they eliminated the 1.5 second delay for sleep after implementing it in Mavericks: OS X: Using the power button - Apple Support

     

    If it is not working correctly I would try two things:

    NVRAM reset which I don't think will help but is non-invasive: How to Reset NVRAM on your Mac - Apple Support

    Note if you've used the TrimEnabler hack, don't reset NVRAM as your Mac won't start up.

     

    SMC reset which deals with power issues: Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support

    Sadly, my Mac didn't have a problem until Yosemite was applied, should be grateful however as the other Mac that was upgraded to Yosemite can no longer use the internet without trailing an Ethernet cable.

     

    Under Mavericks the power button and keyboard performed as described in the document you linked to, under Yosemite they don't. Resetting the PRAM fixed it, until the machine was put to sleep, then upon awaken the issue has returned. I will try resetting all the other hardware based settings, if I didn't need to use Yosemite, I would be back down to Mavericks in a heartbeat.

     

    Yosemite is the buggiest release of the Mac OS, I've encountered in 20 years. It's just not up to Apple's high quality that I'm accustomed with.
