Sometimes My MBP Won't Wake Up

Usually every night I close my MBP to put it to sleep and sometimes when I open it back up to wake it up, it won't do anything. I press keys push the power button and everything and it wont turn back on. It seems to be doing something because I can hear the fans and it is warm
It's plugged in so I know it's not becasuse the battery is low or anything.
Any help would be appreciated.
Thanks

Something like this has happened to me.
The MBP seems to take anything up to a couple of minutes to wake up. It's lazier in the mornings than I am! Under 10.4 it was fine once it had woken up.
Under 10.5 I'm getting weird mouse behaviour once it wakes up. The mouse either updates only a few times per second, making control difficult, or jumps around all over the place making control impossible. Logging out/in doesn't help, only restarting fixes this.
I'm starting to suspect my Intellimouse driver (Microsoft) as a likely culprit, and next time this happens I'll try making my way to the system prefs to disable the Microsoft mouse from there.
I'll also test the power-button tip. Thanks for that!
My wife has none of these issues on her 1st-gen CoreDuo 17" MBP. I think it's a deal we made somewhere - she gets all the smoothness in computing and I get all the weirdness.

MBP won't wake up

My MBP goes to sleep after setting for a few minutes and it won't wake up after that. Although, if I manually put the computer into sleep it will wake up. Of course I'm waking it back up only a couple of minutes afterwards. Basically I end up shutting it down and turning it back on to get going again. Any ideas? Thanks in advance to any and all suggestions.

Here's something you can try. No guarantee:
In particular, some users are finding success with a workaround we've suggested for various wake-from-seep and related issues -- deletion of the following files:

This workaround may need to be repeated from time to time as these files can become corrupt with some frequency.

MBP won't wake up from sleep

My Macbook Pro won't wake from sleep. Does not matter how it goes to sleep. Screen stays black after going to sleep. I have to resort to depressing the power button for a long minute to get it to shut down then push power again to reboot.
Started when Mobile me came in, but don't think that is the cause.

Try resetting the SMC. Here's the instructions

Sometimes my iMac won't wake up...

I'd say 10%-15% of the times it goes to sleep it won't wake up. And it's always when I have something I haven't saved yet. I alway turn it off at night & start up in the morning, so it doesn't run 24/7.
Any thoughts?
Thanks.

The results from the terminal mean that the daily Chron script hasn't run since 9 SEP and, unless you didn't post the entire result, you weekly and monthly scripts have never been run. These are part of maintaining a happy Mac. Since you turn your Mac off at night and these are not running regularly, I suggest that you down load OnyX and run them yourself as part of your regular upkeep for your Mac. Here is a link;

Also, here is a link to a good site for you to learn how to properly keep your Mac in good working order and also for troubleshooting issues. There is a section on kernel panics.

MBP Won't wake from sleep but shouldn't BE asleep

Hi,
I have a couple MBP's giving me trouble. They both are 2011 8,2 MBPs, running 10.9 and have Crucial SSDs installed. Other similar machines and configurations are fine afaik.
They are set to not sleep when power is connected. The hard drives are set to not sleep. Displays are set to go dark after about 15 minutes. Screen savers are set to never turn on.
Sometimes, about once every week or two, when the user goes back to his computer after the display has gone dark, nothing seems to wake it up. The keyboard and mouse and mousepad do nothing. Pressing the power button does nothing; holding it in for a few seconds and force-rebooting finally snaps it back to life. I assume it's powered on and in some sort of deep sleep from which it cannot awaken since the power button does not work unless we hold it in. While in this state remote desktop shows the machines as being "offline," not "sleeping."
I've seen threads about MBPs not waking but since these are set to not sleep in the first place, I'm perplexed.
I've reset the SMC and the PRAM (btw, does pram even do anything anymore? if not, why is it still there?)
Thanks,
Jeff

Does this problem still exist in the newer versions of the OWC firmware?
While my SSD is not an OWC, I've been having this issue with my OCZ Vertex 2, also based on the Sandforce chip.
OCZ's most recent firmware (1.32) has fixed the issues related to hibernation (i.e. "safe-sleep") but the drive still has issues waking from timed inactivity sleep.
I wrote about it on their support forums in this thread:
http://www.ocztechnologyforum.com/forum/showthread.php?86538-Hibernation-works-b ut-wake-from-auto-timer-sleep-problem-still-present-in-1.32
One of their support staff (who has been very helpful in ironing out the hibernation problems) replied with:
"I can tell you this new FW build has been fully validated by Apple at their labs, it may be possible your machine while fine with hdd may have an issue with newer ssd...or the line of macbooks with this issue are looking now for an efi update.
I will pass this back to SF but I suggest you also contact Apple and ask if a new EFI update is coming."
While my machine doesn't often sleep due to inactivity, it does happen. I am not a fan of the suggestion to set inactivity sleep to never. While this is a way around the problem, I don't consider it a solution—I would like the security of knowing that if I ever walked away from my machine on battery power for a few hours, I would be able to return to something that hasn't completely drained itself of battery.

MBP won't wake, is REALLY HOT, fans going full blast

This morning I made sure when I closed the lid on my MacBook Pro, that it went to sleep (pulsing sleep light). I found that this doesn't always happen right away, unlike the old Powerbooks. I then put it into my laptop bag, confident that it was fully hibernating.
When I arrived at work and pulled the MBP out of the bag, the sleep light was solid white, the laptop was really hot on all sides, and the fans were running hard. I opened the lid and there was no display, although I knew it wasn't sleeping because I could hit "caps lock" and it would toggle on/off. Apparently it had awaked while in my bag for some reason. The only way I could regain control was to hold down the power button and start from a "cold" boot. When I logged back in I could not find anything odd in /var/log/system.log during the time before the reboot.
My Energy Saver settings for "battery" mode are set to "Better Battery Life" so theoretically nothing should be able to externally wake the MBP. Bluetooth is Off. I have no idea then what caused it to wake up and flip out. This is the second time this has happened and I've been wary of its sleep behavior. Is there an updated SMC firmware for the 17" model yet?
This is really worrying because I could have left it in my bag for a lot longer and who knows, maybe it would have caught fire!

It happened again. I did a hard shutdown to keep it from really geting hot. After the boot, I checked the system.log. At the time which I suspect the interrupted sleep occured I saw this, which seemed to repeat a few times:

My MBP won't wake up or reboot

My mid-2012 MBP screen went black suddenly (on full charge) and the sleep front light is on. Nothing seems to work to make it wake up. I've tried to hard reboot it a number of times , the light goes off the HDD spins down, and when power it up again it does not reboot, no startup chime, screen stays black, HDD spins up and the front light is on but nothing more. I fully discharged the battery attaching some hard drives and then tried to reboot on mains, same result.
Any ideas or is it a hardware problem?
Thanks in advance

I was having this same issue with a brand new 2012 MacBook Air after updating to Mountain Lion and using an AirPort Extreme. Most times waking from sleep would result in a lockup as the system would continously try to find my network (the WiFi menu would just keep cycling). After going to 10.8.1 it still continued so I started looking at other possibilities. I noticed that the security setting on my AirPort Extreme (current generation) was set to WPA/WPA2. I changed it to WPA2 and the problem so far (2 days in a row) has gone away.

MBP won't wake from sleep with lid down

This has been happening ever since the installation of 10.8.2. i can put my MBP to sleep and leave the lid open, and it will wake without issue. but, if i put it to sleep and then close the lid, the next morning, it will not wake.
when i open the lid, the white "sleep" light goes away, but the display is still black. my only recourse is to force shut down and restart.
has anyone else experienced this?

MBP won't wake for access?

Hi Guys.
I use iTeleport on my iPhone. This is an app that allows me to control my MacBook Pro, and displays the screen on my phone. The app has a server you can download on the computer so that you can use it anywhere in the world, as opposed to only when sharing a network. The same goes for another app called AirPlayit. This app streams videos, photos and music to my phone from my MBP, through a server running on the MBP.
Both of these apps work fine when connecting to the macbook from outside the Local Network, but only for a short period of time. Give it more than five minutes after the computer has gone to sleep, and it can no longer be accessed. I've got "wake for network access" enabled in System Preferences, I've even tried setting the "Computer Sleep" to never, but that didn't work either.
I'm sure this used to work, in fact I know it did, but unfortunately I don't know what changes have been made to the computer since that time, perhaps it was updating to Lion that has disabled this feature for me somehow?
Any help with this would be greatly appreciated, thanks everyone!
Sam

MBP won't wake up or power on

i put my MBP (intel santa-rosa late 2007/early 2008) to sleep by closing the lid.
i went back and opened the lid and got nothing apart from hearing the optical drive make its usual noise.
so i killed the power and tried to boot up normally... again nothing other than optical drive noise and the white light is on at the front of the MBP.
have tried resetting the SMC - still nothing
tried CMD-OPT-P-R during boot - still nothing.
tried swapping out RAM - still nothing.
i get no bong, no display at all.
only indication that MBP is actually getting power is the optical drive noise and the white light. battery also still charges whilst plugged into mains.
any advise please ?

Just to make sure, you have no peripherals connected?
I cannot think of anything else to try, except poking around at the internal hardware. I've heard of issues, somewhat similar to yours, on other Mac laptops, related to the sleep switch. However, since I have been following all posts in the MBP Usage folder, I have not heard of sleep switch issues, nor have I been inside my/any MBP to examine the workings of the sleep switch. Given the timing of your issue (after closing display in sleep), and if you are intent on trying anything/everything prior to a trip to the repair shop, that is one thing you might look into.
Given the apparent variety of issues with solder joints cracking (due to heat, NVIDIA chip, whatever) another thing you could try is gently poking around solder joints on the LB with a non-conductive spudger (plastic or wood).
Another thing you could try is checking all connections inside the MBP.
Note: I do not recommend any of these procedures, unless you really must try everything possible and are comfortable with them. As I'm sure you're already aware, troubleshooting like this could lead to even more issues due to damaging something.
Personally, as has already been twice suggested, I would consider waiting for a trip to the repair shop.

MBP won't wake from sleep

Hey everyone, at first I thought the problem I was experiencing was something I was doing wrong or a setting I had changed accidentally. I don't think this is the case. It is actually getting really annoying having to restart my computer from a hard boot just to be able to use it. Does anyone have any idea on how to fix this? Is there anyone out there having the same issue? Is it Leopard? I have Tiger and never had this problem before.

One would think that the mouse wouldn't matter. Have you tried waking from sleep after using only the trackpad? You may want to consider resetting your PMU: http://support.apple.com/kb/HT1431?viewlocale=en_US.

Hi David,
- Have you tried any troubleshooting steps?
You may try the following steps:
1. Reset SMC as per the following article http://support.apple.com/kb/HT3964?viewlocale=en_US. If this does not resolve the issue then go to step 2.
2. Navigate to Macintosh HD/Library/Preferences/System Configuration and remove a file called powermanagement.plist (drag it to trash, might prompt for a password). Restart the mac thereafter. If this does not resolve the issue, boot to safe mode as per http://support.apple.com/kb/ht1455 and check the issue there. If it works there, you will have to remove the following files to check Macintosh HD/Library/StartupItems, HD/Library/Caches and then restart the mac.
Let me know if this works.

Won't wake up from sleep, sometimes get blue screen and can't get it to wor

I have two problems that may be related. I am using a PowerBook G4 (Tiger 10.4.5). Sometimes when I turn it on I get a blue screen and that's it. Nothing else will come up. I have to do a forced shut down and then restart it with the shift key depressed and run repair disk permissions and then it works okay till the next time it decides to return to the blue screen (once a day approx.).
Also, sometimes it goes to sleep and will not wake up. I have to shut it down and then restart it (sometimes getting the dreaded blue screen).
This just started happening after I installed Tiger.

Hi, vfv. Welcome to the Discussions.

I have to do a forced shut down and then restart it with the shift key depressed and run repair disk permissions and then it works okay till the next time it decides to return to the blue screen (once a day approx.)."Your description suggests a corrupted or incompatible Startup or Login item. As Adrian suggests, my "Troubleshooting Startup and Login Items" FAQ can help you determine which Startup or Login item is causing the problem.
2. As to the sleep problem, here are some ideas for you:2.1. If you are using a Bluetooth keyboard or mouse, see "Mac OS X 10.4 Help: My wireless mouse and keyboard won't wake my computer.".
2.2. Your Mac maybe frozen or hung. Troubleshooting freezes and hangs is not unlike troubleshooting kernel panics: the steps are virtually the same. For a more exhaustive troubleshooting procedure, you could use the steps in my "Resolving Kernel Panics" FAQ.Good luck!

My Macbook pro, (late 2010) sometimes will sleep and won't wake up. then the sleep light flashes.What's the problem

Hi I've been following this thread (along with a different one on the same topic). I've been having the same problem with my ibook. I can add that I have no problem with startup. It's just that the screen "goes to sleep" unexpectedly and may operate normally for a few minutes or a few hours at most. Opening and closing the lid or restarting seems to cause it to awaken but then usually for just a few seconds or minutes. If it is connected to another video display that display continues functioning fine even though the computer screen is blank. In addition the desktop is there and visible faintly or if totally blank can be backlit through the apple logo and can be read. I've had my logic board replaced twice under the extended warranty and assumed it was that but now I'm thinking of the reed switch. Apple refuses to consider any further work under warranty as the last repair was in Jan, 06 and they claim only a 90 parts warranty and the machine is from 03. Any thoughts before I cut the wires? I have reset the pmu, run cocktail and disk utility. Other than the sleep issue the machine works fine. thanks Ronda or anyone else who has any ideas... Dave
