OS X :: Keyboard Stops Working After Mac Mini Wakes From Sleep?
Aug 8, 2007
I have an obscure brand USB keyboard that I am trying to use with my Mac Mini, with one problem: after the Mini goes to sleep and wakes up again, the keyboard doesn't work. The solution is to either unplug and replug the keyboard or restart, but both are I think unnecessary hassles.
What I like even more is that the keyboard will wake the Mini (by pressing the spacebar or something), but won't work after that.
I also tried a plain ol' Apple keyboard, which works just fine after sleeping/waking.
Any ideas on what's going wrong, or how to fix it without replugging/restarting? It's just a keyboard, so I don't see why it should pose as any real problem after waking, so buying a new keyboard is not quite what I am looking for. I may end up doing it anyways (a wireless one to go with the wireless MX1000 I am using) but at the moment I don't want to spend money for a new keyboard.
It's a 1.66GHz Core Duo, 512MB RAM, 60GB HD, OS X 10.4.10.

I got a brand new Macbook Air the other week. I noticed that sometimes, after folding the computer (with the OS running), then unfolding it - the keyboard and trackpad are not responding at the login screen. Actually if I press the keyboard it lights up properly but there is no access to the system. The only thing that works is the power button, so every time I have to power down the computer, then back on again.
Info:
MacBook Air, Mac OS X (10.7.3)

I have Mac mini 2.26 (2009) OS 10.6.3. with apple wireless keyboard and magic mouse. For some time now my mini wakes from sleep for no reason after 20 minutes. I have checked kernel.log and it says that ohc=2 is the reason for wake up. It seems to be bluetooth keyboard or mouse. When I turn off "allow bluetooth devices to wake..." everything seems to be ok. Is there a way to fix this because I would like to be able to wake mini with keyboard.

My iMac is waking up from sleep in the middle of the night. The only clue to what is going on is that is says the wireless keyboard has lost connection.

I'm yet to figure out a pattern, but my Macbook Pro's keyboard will just stop working for several minutes at a time at random points in time...Even if I hit caps or num lock, they don't turn green. Sometimes it'll just happen once every few hours, but I was in class the other day and it would work for a minute, then not work for a few, than work for another minute, etc.

My macbook pro keyboard and my silver Apple bluetooth keyboard (primary keyboard) randomly stop working in Finder can anyone explain? Heres the details:
I usually use my wireless keyboard, and when this happens the keyboard keeps working with everything else, and only stops working in Finder i.e. I can't edit the names of files or even click through files with the arrow keys. (the Macbook Pro keyboard also stops working-only in Finder-during these times too as I just tested..)
Also, Finder keeps working its not frozen or anything, I can click around in it with the mouse and open files/apps, etc.
This has only happened approximately 3 or 4 times (I've had the keyboard since the new ones were released and the computer for 1.5 yrs)
Lastly, when I restart the OS (10.4.11) the problem disappears for a week or more..

I have some strange problem after updating my MacBookPro4,1 to 10.5.7. After a while (can be a few hours) the trackpad and keyboard stop working. When I then put the MBP to sleep and wake it up, both work again but only for about maybe 5-10 minutes. This can be reproduced (put to sleep, works for 5min, put to sleep, works for 5min, etc.) When I reboot it works again for some hours.

I have noticed that my keyboard will randomly stop working after switching Spaces or using other shortcut keys. When I hit the CMD-arrow key to switch spaces, the Spaces box that shows which space you just moved to stays on the screen and the keyboard completely stops working. A logout of required.
Running 10.6.2 with all updates applied.

The last few days my keyboard and mouse have stopped functioning at random times on my macbook. I am running snow leopard. I have to shut the lid to put it to sleep and wake it up to get it to respond.

I have been having a problem where randomly after switching a space the little graphic that pops up to show which space you're switching to gets stuck on screen, though you are still able to switch spaces. Also, the keyboard ceases to work as well. The only fix I've found is fast user switching to the login window and back to my account. I'm not able to trigger the problem, and it definitely doesn't happen everytime I switch spaces, but its been happening multiple times per day and is a pretty big nuisance. Also unrelated question: In my itunes using column view whenever I select an artist it snaps back to the top of the list, though still selecting the artist. Its a weird bug, anyone else having this happen?

I purchased a new iMac a month ago. Often, the keyboard just stops working and the computer has to be restarted for the keyboard to work again. Another problem: Unless I plug my printer in with a USB, the Mac does not pick it up. The printer is a fairly new HP Officejet J5780.

My Apple Wireless Keyboard is haunted. It will randomly, in the middle of sentences, or sometimes after I haven't used in a few minutes, stop responding.
The really weird part? I open System Prefs, click Bluetooth, and viola! It works again. I don't have to do anything - just open the Bluetooth prefs. As soon as I do, everything I've typed since it went dead (usually just a word or two) is actually output into the search box in Systems Prefs.
There is no rhyme or reason to this weirdness. Sometimes it will literally happen a few times an hour for days (which drives me up the wall); sometimes it'll go months without doing it. When it's doing it a lot, no amount of rebooting/relogging-in fixes it. One thing I have not tried is using a fresh user account (or Guest), because it's so unpredictable... even on my own account it will take a break and work normally for a few hours, then go right back to freaking out.
The fact that it stores everything I type when it's "not working" is the really weird part. It's like the OS is receiving the data but just forgetting to process it until I poke it and remind it, "you have stuff coming in via Bluetooth, wake up and do something with it!"

On a day-to-day basis I run: Adobe PS, INDD, and AI, Microsoft Entourage, Firefox and iTunes. Just recently, after an upgrade to Leopard, I added Things and Simplify Media to the list.The problem that happens before (on Tiger) and now (on Leopard) is command+tab switching stops functioning and Expose hot corners and shortcuts stop working.
I'm pretty sure this isn't a Finder crash because before, on Tiger, I could quit+restart Firefox and everything would be back to normal. Almost as if some shortcut had causes the system to act differently or there was some app dissonance?
But now, with Leopard, nothing I quit will cause these two features to act properly until I do a restart. Both features (command+tab switching and expose) are very necessary for my work flow. I have checked SysPref to make sure keyboard shortcuts are default and Univeral Access to make sure assisted devices is turned off.

I'm well sure this topic has come up before, but I've never seen it answered.
After waking my Mac mini from sleep, my keyboard won't respond at all. I tried:
- Plugging it into a different USB port, including the one on my monitor
- Using the mouse to wake the computer up from sleep instead of the keyboard
- Switching to a different, wired keyboard (had a wireless before)
Both keyboards used were off-brand (non-Apple) keyboards, but I've had a couple before these two that never had a problem whatsoever.

I see my screen popping on for no reason staying on for 5 minuets or so then going back to sleep. Is this normal? I don't recall it doing this before but I have added an old p.c. to my network and got an iPad. Don't know if ether of those things have any relevance but like i said, I don't remember it happening before. From what I understand, to get spyware or malware on the computer I need to instal it. But I could be wrong. I have an iMac running 10.6.4.

I just upgraded to Lion, on a MacMini, and now everytime I use sleep mode, I can't wake my lion up again because key presses or mouse clicks don't work anymore. I can still move the pointer, but OS does not respond anymore to mouse clicks or keyboard. Have to power down, then start up again. Keyboard & mouse then work until the next time the lion sleeps.Â
This is quite annoying, as I'm an intermittent style of user who relies on sleep mode a lot. Â
Lion is nice when it works, but it has introduced problems I've never had before. And booting into Lion is way slower than Leopard or Snow Leopard were. At least double the time, or more.Â
Should mention I'm also using a Logitech denovo wireless keyboard and a Logitech M570 wireless trackball.Â
Connecting a standard USB keyboard and/or mouse, once the lion has gone to sleep, does not solve anything. The OS still does not respond.Â

Since installing Yosemite I'm seeing a random issue where, after waking my Macbook from sleep, keyboard input is not possible. I can move the mouse using the trackpad, and applications all appear to be running as normal. I can quit applications from the dock also using the trackpad. When trying to type anything I get the 'bong' sound as if input is blocked. The only fix I've been able to find is either to ssh in from another machine and force a restart, or to force a power off using the power button.Â
I've tried searching the console logs and can't find anything relevant happening at the point this fails. I've also considered that it could be any number of applications misbehaving, but having quit everything running that is visible in the dock, keyboard input still isn't possible.Â

I've owned my G5 for 3 years and recently when I put it into sleep mode it immediately wakes back up. I have a screen saver password so it asks me to enter the password, if I don't it goes back to sleep, then immediately wakes up. It repeats this process a few times before finally going to sleep. This is very weird because I haven't installed anything or changed any settings.

My MBP sometimes wakes up from sleep for no apparent reason. I have it set up in a closed lid/external monitor mode, with a bluetooth keyboard and a wireless usb mouse. To make sure it's not USB activity, I unplugged all USB devices, and switched the USB mouse off. Also made sure "wakeup on ethernet access" is disabled in system prefs, and software update is turned off. Looking at the console, it woke up with a reason:
Wake reason = EHC2 OHC2
Do you know what that is?
Below is a system.log snapshot and console messages when it woke up. Any ideas about what caused it?

I have a hot corner to put the mac display to sleep. Whether I use that or I use the 3 buttons to put the mac display to sleep, it wakes up after a while (probably due to some activity on the net or msn etc...) Is there a way to keep it asleep until I wake it up manually?

This is has been occurring most every night since I've had this MBP for a few weeks. I put the MBP to sleep at night. Then some point in the morning, I can actually hear it wake, but then quickly, within 5 seconds, it right back to sleep.
I have no programs telling it to awake or perform scans, my Bluetooth mouse is off, etc. Has anyone experienced this or know how to resolve it?

After a few hours of uptime, certain keys on my keyboard stop working and I have to reboot: both command keys and the zero key. Sometimes, after the computer has been in sleep a long time, the keyboard and mouse don't respond at all. I can get the computer to wake up again by pressing the power key, but the mouse and keyboard don't respond, so I can't do anything except hard boot. This problem first appeared after the update to 10.10.1. (I'm dealing with it right now, so I'm getting the '0' through the keyboard viewer, but there's no way to access that from the password screen.)

MacBook Pro (15-inch Early 2008), OS X Yosemite (10.10.1)

Whenever I select Apple sleep it goes to sleep but immediately wakes up.
I have taken off all devices and it still happens - but really, it started this after working with the same devices for many months.
It is immediate after going to sleep, the next second it wakes back up.

When I go to bed, I like to just put my macbook pro to sleep by closing the lid. But almost 100% of the time it wakes itself. It gets really hot when this happens so I've been turning it off most of the time instead, but I'd really like to get this resolved. I have an external monitor plugged into it so I know its awake as the screen shifts over to the external monitor. When no monitor is plugged into it, I do occasionally hear the hard drive spin up. I have tried unplugging everything except for the power cable to see if that might help, but the result is the same. I have a 1st generation 15" Macbook Pro running OS X 10.5.3.

My MacBook Pro has been waking up from sleep at some of the most random times. Usually it will wake up about 5 minutes after I put it to sleep, and if I'm lucky it will stay to sleep when I try again. Sometimes it will even wake up 30 or 45 minutes after I put it to sleep. Currently, I have it connected to an external display with the laptop screen closed at all times. It is running a fresh install of Snow Leopard with barely any apps installed yet (mainly just iWork and Microsoft Offiice). I was having the same problem when I was running Leopard, thats why I did a fresh install. So this eliminates a software issue.
This has been happening for a few months now, but it has just started to become a problem for me. When I was running Leopard I did not have an external display. It was waking up at random times without anything connected to it (no display, USB, or MagSafe connected). I would be sitting next to my Mac, and all of a sudden, I hear the Superdrive wake up sound. I searched and found a thread similar to this, but hopefully it will not have the same solution as the members of the following thread had: "I had this problem with my Macbook. The fix was a logic board replacement." [URL] I have also attached a screenshot of my system.log in Console. I opened up console as soon as my MBP woke by itself. Hopefully someone here will have some idea what all the stuff in console means or maybe be able to narrow down the problem.
