Problems Waking from Sleep

Symptoms: For the past 2-3 months I have been having difficulties waking my 13in MacBook Pro (purchased May 2010) from sleep. The problem came on slowly, but then started to get worse and worse until every time I open my computer lid I have to manually restart (hold down button in upper right corner of keyboard). When I open the laptop, the fan always starts going, but the screen remains black. Sometimes when I manually restart, I get the hazy screen with the progression of vertical bars across it and then within 1 minute, my computer restores itself to what I was working on before entering sleep mode. However, now it mostly involves a complete manual restart.
Genius bar diagnosis and treatment: When I brought it in 2 weeks ago, it was presumed to be a software problem. My whole computer was erased and restored back to factory settings. The problem persisted, though it was not as frequent as before the system was reset. I brought in my computer again two days ago and this time they kept it overnight to run full diagnostics and look at the hardware. Nothing was found to be wrong. They say the next step is to send it off to look at the Main Logic Board, but I would like more opinions before I pay that hefty price.
Past history: in the 2 years since I have had the laptop, the link cable to the hard drive has needed to be replaced twice. Additionally, (probably unrelated, but who knows), my charger short circuited on me about 6 months ago.
Perhaps this indicates mishandling, but I am extremely careful with my computer. I transport it in a hard case shell along with a padded Incase. Being a college student, I need a personal computer and I treat my Mac very well with all necessary precautions. I am more than a little upset that having made such an investment for an Apple laptop that now Apple is not holding up their end of the deal.
Help, please!

Me three; I just got my pb, so I was worried that this was a hardware flaw. You've both had yours for some time, I take it, and this just started happening (presumably, right after an OS update)?
I always closed my G3-500 iBook lid and tossed it in my work bag with hardly a care, and it never disappointed me by failing to wake up in exactly the same state in which I'd left it -- until the day it bit the dust, almost a month ago. The PB has really been a disappointment so far in that regard. Seems like every other time I close it, when I open it up again it's mysteriously switched itself off.
I will try the old CmdOption+PR and see if this happens again afterward.

Lacie Speakers and Mac Pro Firewire problem waking from sleep and loud feed

Lacie Speakers and Mac Pro Firewire problem waking from sleep and loud feedback. I had a powermac before this with the speakers and it worked fine. But the mac pro is having these issues. Is it the firewire port or the speakers or (and most likely) just a firmware glitch with mac pro? Anyone else see these issues?

http://web.mac.com/jerimydulay/Site/MyAlbums/Pages/Lacie_FirewireMIDI.html
Here is my audio settings. For some reason I wish I could remember what I did. It was actually the Apple Store tech in the Unversity Village in Seattle that gave me the idea and I swear I had to change the settings in MIDI setup. Now that Leopard is out it seems the MIDI stuff has been redone. I included screenshots of my MIDI setup as it is currently to see if you see something different on your computers. Let me know!

2 Lion Problems: Waking from Sleep Doesn't Go to Wifi Network; & Can No Longer Finger Swipe in Firefox to Move Backward/Forward

I hve a late 2009 iMac at home that I've upgraded to Lion. So far, there are only 2 issues that I'm having:
1 - When I wake the iMac from a long sleep, it doens't automatically log into my wifi network. I have to drag the mouse up to the menu bar, click on the signal icon and choose my wifi network. A few tiems yesterday, the computer stopped recognizing the network while I was in the middle of surfing. Haven't had that in a while, but the inability to log in directly after waking up remains.
2 - I use Firefox to surf. I can no longer move backwards and forwards between pages by swiping left or right. It works in Safari, but not in Firefox. Is that a new functionality that has to be rebuilt into Firefox because of Lion?

I have a similar wifi problem after installing Lion. When my computer goes to sleep or I turn my wifi off, it won't reconnect to my wireless network. I have to manually select it and then retype my wep password. It tries to connect and then says "connection timeout" and the login failed, however, even though it says that it was unable to connect, it actually does connect and I get regular connectivity. Frustrating.
I have a 15" core i7 2010 MBP.
@Caleb was here. I had the same issue before I switched to Lion, turned out it was some issue with my router. I bought another router and I haven't had the issue since. Try changing from WEP to WPA (you should do this anyway) and see if you have the same issues still.

Imac 3.06 ghz problem waking from sleep

I've got my IMAC which I leave on and is set for the default settings for the display and computer sleep modes. I'm finding on some occasions the computer and display won't wake up and come out of sleep mode. On some occasions it does. I'm using the bluetooth keyboard and mouse that come stock with this IMAC. When this happens I have to force shutdown and then restart by holding the power button down til it turns off and then starting it up again. On many occasions I've been able to get it out of sleep even after it's been overnight yet I'm regularly having this problem. Can anyone advise if there's a fix to this and how I should deal with it.
Thanks

If what arnie suggested does not work, you could try performing an SMC reset: http://support.apple.com/kb/ht3964

I have the latest firmware... still having problems waking from sleep

First off, I want to say that I have the latest firmware updates and have had them for a few months: SMC version 1.4f12 and Boot ROM version MB11.0061.B03.
The problem I have most often when trying to wake is that the password dialog will come up, I'll enter my password, and then the MacBook will just go back to sleep! Sometimes the screen unlocks for a few seconds and then it goes back to sleep completely (i.e. backlight goes off), and sometimes the password dialog just goes away and I get the spinning beachball on a black screen indefinitely.
Is anyone else having this problem? Is there a fix? Am I NOT actually running the latest firmware?

Try resetting the SMC (I would also repair permissions before and after - in disk utility)

Hope this helps,
Cheers

Can iMac not waking from sleep be caused be a corrupt file

I have had my 27" iMac from July of 2011 (running Montain Lion, 8 GB RAM, 2TB hardrive, 3.4 GHz,Intel i7) for over a year and a half and ever since I bought it, it has had a problem waking from sleep. I can hear the computer running, but when I click the mouse, keyboard, or power button, it stays asleep and I am forced to do a hard shut down. Apple has been trying to fix the issue, but to no success. They have replaced the hard drive, logic board, usb ports, RAM, mouse and keyboard, but it still happens. They finally threw in the towel and are replacing the machine. They offered to transfer all of our files (jpgs, mp3s, docs, videos, etc), but one thought occurred to me... what if the sleep issue is caused by a corrupt file? I highly doubt that is the case, but wonder if any of the experts out here would know better than I.
If we didin't have the data transfered, we would just keep it on an external hard drive instead. But, I would assume that it wouldn't matter if the files were on internal vs. external because either way, the computer would access the files. That being the case, if the sleep issue was caused by a corrupt file, the computer would still access it on the external and the sleep issue would resurface.
So, 2 questions:
Can a corrupt file cause the sleep issue?
If it is true that a corrupt file can cause the sleep issue, would it matter if the corrupt file was accessed from an external drive vs. internal drive?
Thanks so much!
Chris

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether your problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Mac Pro restarts instead of waking from sleep

Since installing 10.5.6, my 8-core Mac Pro (early 2008) has lost the ability to wake from sleep. It seems to go to sleep pretty quickly (if a little faster than before), but when I wake it up by pressing a key on the keyboard, I hear the Mac startup chime and watch as it restarts.
I've manually shut down and booted up a few times now, and the sleep misbehavior continues.
Anyone else? My 10.5.6 MacBook has no problems waking from sleep, only the tower.
--Chris

Well, I thought this was resolved a couple of weeks ago after reading a suggestion that called for doing a controlled shutdown, then unplugging everything including power, waiting a minute, replugging only power, and starting up, using the power button on the front to sleep and wake up. It seemed to be waking instead of restarting, and was working normally for about three weeks.
As of today, I'm back to restarting when I try to wake. I have tried the unplug-everything trick again, and have zapped the PRAM multiple times (seriously, though, does that EVER work?). Nothing helps.
As mentioned above, I'm already on the BootROM version that EFI Update 1.3 provides, so that's not an option.
Thinking the next stop might be the Genius Bar, in hopes those guys have seen this.

New MBP BUG!!!!!? mag safe and waking from sleep..............

I have found that if you are running on battery power, and then put the computer to sleep, that if you plug in the mag safe power whilst the computer is asleepit will refuse to wake up and require restarting. Not a massive issue but i would be interested to see if anyone else is experiencing this small bug?

It is possible that the difficulty you are experiencing waking from sleep is related to the "safe sleep" feature. I, too, had some difficulty waking my MBP from sleep (though I didn't specifically notice any link between these difficulties and the power adapter). Since I disabled safe sleep, I have had no more problems waking from sleep.
Information about the safe sleep feature (which backs up open files and settings before your computer goes to sleep in case of a loss of power during sleep) is here:
http://docs.info.apple.com/article.html?artnum=302477
More information about safe sleep is found on at least two discussion posts:
http://discussions.apple.com/thread.jspa?messageID=1546493&#1546493
http://discussions.apple.com/thread.jspa?messageID=1136215&#1136215
Finally, to hit the key point of these two threads linked above, you can turn off safe sleep by opening Terminal and typing:
sudo pmset -a hibernatemode 0
I hope that helps!
Take care.

Start up and waking from sleep problems. early 2011 macbook pro i-7 2.0

Been having problems with my computer starting up and waking from sleep. If i shut the lid it wont wake up upon reopening the lid unless i hit the power button. After hitting the power button it will restart automatically and you hear the chime and the cdrom ejecting , once the gray screen pops up it restarts again this time you hear the cd rom making the ejecting sound twice then it will start up as normal. Once it finally starts up my date and time has been reset to jan 2008. Other times when i open the lid hit the power button it does nothing at all. Even holding the power button for multiple seconds to force shut down it does nothing. Only way to get it to start up at that power is if i connect the charging cable. I have tried reseting the smc multiple times with no results and pram(even though it doesnt have anything to do with start up problems just did it anyways). It all started i last time i updated not completely sure what all updates i got but im still running 10.7. It seems like a battery issue which would make sense since its nearly 3 years old and i use it extensivly. Last thing that just started recently after i go threw the whole mess of getting it to start up if i pick it up or nudge it the thing will just shut off out of no where. Almost like there is a short somewhere, cant really be sure if its linked with the waking up from sleep/start up problems but seems right up the same ally. Any suggestions to what could be wrong would be greatly apreciated. Im assuming my battery may be on its last leg but the thing still holds a charge and my battery life hasnt dimished at all so cant really be totally sure. Thanks agian

Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. It may not fix the problem but it would be the first thing an Apple Store would do if you were to bring it to them with this complaint.
If bumping the Mac causes problems it's an intermittent internal connection that the SMC reset is not likely to help.
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.

Workaround for the problem of ultrabay HDD ejecting when waking from sleep

After trying every possible "solutions" with no luck for the problem of the second hard drive always ejecting/disconnecting when waking from sleep in my T530, I've decided to create my own workaround.
This is by no means a definitive solution but a nice workaround that uses little resources on the machine.
The idea is to simply let a program runs constantly from the second hard drive. That way, when the HDD tries to disconnect, Windows is not allowing it and then it stays allways connected.
To make it more thansparent I decided to create a Windows service that starts when Windows boot and stops when Windows shutdown.
This Windows service is very lightweight : it does absolutely nothing and just waits indefinitively.
The trick is that it just have to be started from the second hard drive.
Here is a link to the Windows service, 32-bit and 64-bit, with the source code and scripts to install/uninstall.
Just install it anywhere on the second hard drive (D: in my case).

Works perfectly for me on my T530 with Windows 7 Pro x64.

Hmm, I have no problem with Ultrabay ejecting HDD when waking from sleep mode. At first, I went down the same
route as you did. For the first few days when I received my T530 I kept an .iso file from Ultrabay HDD always mounted.
But then I disabled all power saving options within Windows and Lenovo Power Manager and it seems to work fine.
Works both with Windows 8 (64-bit) and Windows XP Professional (32-bit).
T530: i7-3630QM, 4 GB DDR3-1600, NVS 5400M, 2x 500GB 7200RPM, 9-cell, HD+ 1600x900, Backlit US, WinXP Pro

Problem when waking from sleep

Hi all, my mbp has real problems when waking from sleep - I hear the dvd drive do something, the screen comes on but remains black, and then nothing else - no keys work, only holding the power button has any effect.
I have a screensaver password on.
Anyone heard of this before or have any ideas?
Thanks!

On my new iMac, mail has no sound after waking from sleep. If I select do not wake for network access in general preferences, the problem does not occur. Anyone have an idea on how to fix this?

Same here on an older iMac since Lion. Thanks for the uncheck wake for network access tip though, it doesn't do it either in that case, I will leave it that way.

Connection problems after waking from sleep????

I'm having a strange issue with my 2012 Macbook Pro running OSx v10.8. I take my computer with me between home and school, and I usually just put it to sleep during the commute. For the last few weeks, when I got to school and woke up my MBP, it wouldn't connect to the internet. It recognized the WiFi connection, but did not assign a valid IP address. It was only when I shut the computer down and rebooted it that I was able to connect. Strangely, when I got home, I had no problem connecting to my home network, even after waking up from sleep.
After a little while of this, it got worse. Now, even after re-starting, I am unable to connect at school. (WiFi icon shows exclamation point). This is also true for my home network.
Here's the kicker. When I log out of my default account and log into the guest account, I have no trouble either in school or at home. Waking from sleep is never a problem and I connect everywhere. However, as soon as I log back into my other account, I lose connectivity.
I have tried renewing my DHCP lease, or manually inputting an address, but neither of these have worked. I have resorted to using the guest account, and I want access to my old files again without having to switch back and forth.
If anyone has any input on this, it would be greatly appreciated!! Feel free to e-mail me at [email protected]
Thanks!

same issue here..
reset my network settings and reset phone a billion times already, same issue still occur. sometimes the phone will wake up with wifi and sometimes it will go to 3g, one time it went to GPRS, its just really bizarre. If i open safari it will ask if i want to join the network that i originally set up, but when i select the network it just says "unable to connect". If i just leave the phone be for a couple hours and wake it up again, it will rejoin the wifi network.
I use remote to control my music library, but if my phone goes to sleep, it won't reconnect again so it's basically useless.
BIZARRRRRE, driving me crazy..

My zero Key isn't working after waking from sleep mode. This is a real problem for me because my password contains a zero

My zero Key isn't working after waking from sleep mode. This is a real problem for me because my password contains a zero. I don't recall spilling anything or jamming it just that it worked before I closed the computer and wasn't after I woke it up.
I would like to fix the key but if that's not possible right away , Is there a way to reset my password without being able to type with a key thats in it?

Start by swapping the keyboard. You don't need to spend a fortune, and handy to have spare. USB cables can be bad even new.
When I had some problems Apple wanted to blame the mouse, keyboard, cable, but in the end I found
A. run Disk Warrior
B. Corrupt pref or conflict with version of Hardware Monitor and other background tasks

Anyone's MacPro have problems after waking from sleep mode?

After waking from sleep, my MacPro 2x2.4 Quadcore Intel Xeon freezes in several applications that had been running before sleeping. Mail and Firefox both get into endless loops trying to download data and will not force quit. Pulldown restart and shut down do not function when this is occurring. Must shuyt down manually from box and start again. Everything works fine again until it goes to sleep again.
