When I close the lid on my retina MacBook Pro with Thunderbolt and it goes to sleep, I cannot wake it without shutting it down and restarting it. Called Apple tech and they did not have a solution. Any ideas?

Macbook Pro 15 inch goes to sleep and then wakes

The Macbook Pro 15 inch computer is going to sleep while in use and then wakes up. No magnetic items are close to it. It is the strangest thing. We will be using it then its screen goes black/to sleep and wakes up after a few seconds. I thought that maybe it was Opera that I had open so I shut that down. I opened and was using Safari then it repeated. I tried restarting but it made no difference. Any thoughts on this or ideas of how to fix this?

I would try a SMC reset.

Macbook Pro keeps randomly going to sleep.

My OS Lion Macbook Pro keeps randomly going to sleep.
There doesn't seem to be any pattern. It looks like I may have to get it repaired?

No I didn't do anything like that, but...
I've found a pattern/cause!
It's every time I open the app store. Why on earth would that be?

MBP goes to sleep, won't wake up!?!?

Recently my MacBook Pro has began going to sleep, either after not being used or after I shut it, and then it won't wake up and has to be restarted manually, which costs me data, time, etc.
I've researched the problem, but haven't seen anything that sounded exactly like what I am going through.
Plus I'm not the best at fixing stuff myself (lets just say I'm not going to get hired as a MacGenius anytime soon).
Help me! I'm writing my National Board Papers right now and need my machine to be reliable!!!
Thanks in advance.

I have just started having the same problem. I used to be able to use the MBP for a few minutes, leave it on the table and let it go to sleep. Come back anytime and it would wake. Now it won't, and I have to go back and plug it in to get it to wake. I have just now noticed that the battery is almost drained. I used to be able to do this for a couple of days without charging, and now it won't make it 12 hours.
The battery being almost drained would explain the no wake, but now the question is why it is draining so quickly even in sleep mode. Especially when I used to tell everyone how great the MBP is, and how long the battery lasts and how quick is starts up. Of course I was telling this to all my co-workers where we are stuck with the company issued Dell.
I think this may have all started after upgrading to 10.5 or iLife08, as those are the only two programs that have recently been added.

HP OfficeJet Pro 8500 goes to sleep, but often wakes up when it shouldn't

HP OfficeJet Pro 8500 goes to sleep, but often wakes up when it shouldn't. This happens over and over. It used to sleep until I sent something to be printed. I now shut the printer down, but that takes a long time to start it up.

When you finally get around to looking at my post, never mind.
I reset the factory defaults on the printer and reauthorized my WiFi network.
Now it is working.

MacBook Pro mid 2010 goes to sleep right after booting

Hello and thank you in advance to anyone that can help me. I have a MacBook Pro mid 2010 and I recently spill tea on the computer. I took everything and dried out everything hoping and praying that it will start again. I put everything back together and it started but right after starting (like 15 seconds after) the monitor goes to sleep right away. But here is the weird thing; I have Windows 8 installed on bootcamp, so if I start on bootcamp, it starts with no problem. I am actually writing this from my macbook but on bootcamp. Any ideas why it goes to sleep on Mac but in Windows seems to be working just fine?

Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. The power adapter indicator light will cycle off / on once.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

When i unplug my headphones from Macbook pro, the laptop goes to sleep

When i unplug my headphones from Macbook pro, SOMETIMES the laptop goes to sleep and the sleep indicator light is solid instead of plusing, but it pluses when i close the screen, or click the sleep from apple icon. Can someone help me? Thank you for your valuable time.

Open System Preferences > Energy Saver
Click: Restore Defaults
Restart your Mac. Try unplugging your headphones ..

Macbook pro goes to sleep doesn't wake up...noticed the light on the power cord not on...

My MacBook Pro goes to sleep and this time will not wake up. I hold the start button down for count of 10 without results. I noticed the light on my power cord isn't on...and I've jiggled the cord and plugged it into a working outlet. Help!

All Apple laptops will go to sleep when the battery gets low, during this sleep you will not be able to wake it up. based on what you are saying, to me it sounds like the battery is low because your power supply failed. I would recommend either barrowing power supply from a friend, or bring it to the apple store, that way you can test it with a good power supply, it that is the case, replace it.

When it goes to sleep, can't wake up screen but power still on

When I leave my macbook idle for a while or close it, it goes to sleep. When I come back to it later, open the screen, try moving the cursor or pressing the power button, sometimes it doesn't wake up. I see the light at the bottom right corner is lit and I know it's on, but it won't respond, so I usually resort to just holding down the power button until it shuts down so I can restart. I know I shouldn't do this, but I don't know how else to get it to work.
Is there something else I can do to wake up the screen, or is there a problem with my macbook?

Hi yelomelon,
If you are having unusual issues waking your Mac from sleep, you may find the troubleshooting steps outlined in the following article helpful:

My computer is going to sleep and wont wake up by touching keyboard or mouse. I have to use the power button

Can anybody help? My computer is going to sleep and I cant wake it(bit like a teenager) by using the mouse or keyboard. I have to use the power button. Any ideas?

Hmm, that support link doesn't like me.
Do you have the discs that came with the computer? If so, put Install Disc 1 into the combo drive and boot up while holding the C key. Does anything show up on the screen? Do you hear the fan running? When running from a CD or DVD, the fan usually runs at a fairly fast pace and should make some noise.
Keep in mind that you have a 1-year hardware warranty with any new or refurbished Mac, so if something has gone wrong, you should be able to have it replaced free of charge, unless the MacBook shows some form of damage.

Mac air goes into sleep won't wake

MacBook Air goes to sleep as normal, but won't wake up now.

A new mini is on the way & I'm researching UPS's. A question that I now have is -
The new mini will have 10.5 which will be nice, but I really want to put my old hard drive straight into the new unit so I can have my old computer back the way I like it. Right now I have my external drive with everything on it plugged into my wifes macbook, & I can access everything except my email. The old emails are there in the folders, but as numbered icons, & I can't find anything. With my business I often have to refer back to old emails, & right now it's really hard to. I have tried to import them into mail, but it says it doesn't recognize them.
If I do this, can I put the new backup discs in & load leopard onto the old hard drive without loosing my old information & setup? We are on a very slow dial-up here, so I've never been able to accept the automatic updates. I look forward your advice.

Mac Pro goes to sleep and wont wake up

Any idea how to stop the Mac from freezing up when it goes into sleep mode?
First the screen saver comes on and then after a way it goes into hibernation and then can't be woken.
It use to wake but suddenly decided not to. Nothing's changed.

Well, as you can see from the long discussion on Creative Cow, the XD Cam issue is complicated and seems to be a hardware issue with Mac Pros. Disconnecting the fibre channel card seemed to have worked for one person. I haven't got one of those as far as I know! But then my crashes aren't as constant as his and seem connected, in my mind, with the odd way FC garbles the aspect ratios of Ex 1 footage, especially if mixed with filters and other codecs on the same time line... but some people swear it's the hardware not the soft that's the problem.
Anyway, I've had the hardware... RAM, Disk issues etc... all triple checked out and can't find a problem.
But still Finder takes six seconds to find anything and I think that has caused some crashes.
It doesn't seem to like Soundtrack Pro at all! (You can find a mixed bag of experiences on that issue as well.) And Motion works a little bit too jittery for my liking.
It might be that there are several different flavours of mother board, some not as geared up to this software as others. That's my theory at the moment. The only way to check is to stick my hard drives into the machine of someone who says they don't have any problems.

IMac goes to sleep; won't wake up

After burning my first DVD I noticed the iMac goes to sleep, the light pulsating for a few moments then it disappears (screen is still dark) and it will not wake by touching keyboard or moving the mouse. (I had to unplug it and hit start-up button to get iMac back up & running).
It seems to run fine except for this sleep issue. I can re-awake it at the stage where the screen saver is still on; after that it's in a coma. I have deleted the com.apple.systemuiserver.plist file (suggested by Dale in another post).
I know I can set the computer to "Never" go to sleep but is that a viable option? And, may this sleep problem be a symptom showing some problem exists w/ the power supply or the logic board as I've seen described in other posts. i.e. Should I be calling in the Apple Care people to diagnose my comatose Mac?

I called Apple Care; the tech ran through a process involving unplugging all peripherals, etc etc; the end result being that my iMac is diagnosed w/ a power supply issue. It will qualify to be repaired under the iMac G5 Repair Extension Plan, free of charge. (My iMac also needed a logic board to be replaced 6 months after purchase in Jan. 2005.) My advice: don't purchase the "first generation" of a product line; too often the kinks haven't yet been worked out. If you must make such a purchase, buy the extended warranty (the ProCare plan) and protect your investment.

She goes to sleep and never wakes up - among other things

I just installed SL and I seem to be having a myriad of problems:
1) when she goes into sleep mode, i can't wake her up unless I restart the machine. All I get is the spinning beach ball.
2) she is definitively NOT faster
3) I don't see anything new or different anywhere on my system. I was really excited about the new podcast feature but I can't find it anywhere on my system
4) I ran disk utility to do repair permissions, and that didn't fix anything. In fact, a few repairs couldn't be made.
I'm thinking that i should just just uninstall it - but i have no idea how to do that. Should I try to fix it or just I just do the uninstall and wait until the software updates come out?
Thanks for any input!

What new features are you mentioning, specifically?
The bulk of advancements w/SL are under the hood it would seem.

Whenever my macbook 10.6.8 goes to sleep, I cannot wake it up.
