MacBook Air :: Cannot Log Back After It Went To Sleep?
May 31, 2012
I get my picture and little password 'window' to sign in/log in, but even if I put the correct password in it just shakes 'no'.Next to the password box an arrow points right, but if I click it it just shakes.After attempting to sign in an 'up' arrow appears next to the right arrow in the password box, but clicking on it does nothing?I had been working on and off for hours on an important letter and don't want to lose it.The first time I tried to get back in after a period of sleep, I got a message that a user was logged in and if I attempted to sign in they

Mostly when I am streaming video..or at times the fan comes on, it sounds super high then boom. sleep mode again. After hitting the space bar, it comes back on, but it'll happen again shortly after. I've played with the sleep settings

As of last night, my MBP started acting very strangely. After entering my username and password, it would enter the desktop for a short period of time and then kick back into sleep mode; the screen would turn back to black. Sometimes it will let me stay on the desktop for a long time and other times it will hardly let me stay on the desktop. I called apple support and they had me start the computer in safe mode; even then it occasionally kicks me out.
The tech guy said that it was a "strange software issue" and not a hardware issue. I thought it was a hard drive issue; my hard drive makes an odd sound when it unlocks (a grinding sound), but it has been doing that for quite some time with no issues. I tried to reset the SMC and it didn't do anything.
How should I remedy this problem? Is this a hard drive issue? Hard drive failure? Has the grinding sound finally caught up with me? I am running OS X; not leopard or snow leopard. I know I need to upgrade, but this shouldn't be happening.

Sometimes when I open the MBP after it's been in sleep mode, the screen won't turn back on. I hear the disc drive power up, but nothing on the monitor. I have to turn the computer off and restart it.

This is driving me crazy. I have tried so many fixes but nothing has worked. Every time I hibernate / sleep my 2012 macbook air, the wifi drops and takes at least 20 minutes to come back on when I open the laptop again.Â
I can reboot, turn the wifi off and on, change preferences...everything. Nothing works.

I am new to this forum, but hoping I can get an answer here. When placing my Macbook Pro in sleep mode by closing the lid, it goes into sleep mode, but immediately turns back on (with the lid closed), then after a short time goes back into sleep mode and then immediately turns back on. It keeps cycling like this. Any clues to why it will not stay in the sleep mode?

I have an older iMac (MA589LL) that I recently upgraded to 4GB and Snow Leopard which is running beautifully. I do have an issue with it though, and it's been occurring for a while: Whenever the machine goes to sleep and I wake it up, the monitor turns on just fine but after about 5 seconds it goes back to sleep. I have to repeat this about 3 times and then it is fine. It's an annoying issue but not a deal breaker as I can just turn it off. I searched for sleep issues/turn off issues and have not found anything.
NOTE: Issue occurred before the upgrades. I've also tried resetting the PRAM and NVRAM. I have also used different keyboards/mouses.

About a year ago, I convinced my mom to replace her old Flat Screen iMac G4 for a Mac Mini. We decided to buy a 23" HANNSpree LCD display, connected via Mini DisplayPort to VGA. Since then, my mom has often experienced the same issue: It is often unresponsive to waking from sleep, and sometimes it takes *ages* to come back to life, especially after the computer has fallen asleep for a long time (overnight).Sometimes, though I know the mini is awake, the display says that it cannot detect a signal coming from the mini.

having a weird problem since my Lion install. It's happening randomly, with no peripherals attached. I will open my MPB as it has been sleeping closed; the passcode screen will pop up but before I can type, the screen goes black and it goes back to sleep. I press keys, click the trackpad, everything I can think of, but it doesn't respond. When I close the laptop, wait a minute, then reopen, the same thing. The login screen pops up but then blinks out black before I can do anything. Â

I leave my imac on at night, from screensaver it goes to a black screen but I have selected that the hard drive never goes to sleep. In the morning when I click the mouse or a button on the keyboard it shows me a frozen screensaver screen and the imac is totally unresponsive. Have run disk utility and everything seems totally fine there. It is impossible to use the force quit option so have to resort to switching the whole thing off from the power button.
The software is all up to date and since disk utility shows everything in perfect working order I am puzzled what this is. A corrupt file or app? I am not a heavy user so no games installed - only software installed is the caffeine app, microsoft office for mac which is compatible with my imac, skype and that's all. Lots of free space on the hard drive too. I am not an expert on macs so I don't know how to look in case something in specific causes this that I can uninstall.

Set the computer to output to speakers, keyboard vol controls etc control the speaker sounds and "pop" out of the speakers.
Sleep the system and it reverts back to the internal speaker, even tho the output from iTunes, Quicktime or whatever comes out of the speakers.
Does this happen to anybody else?

I've a problem with my PowerBook G4 (12-inch DVI and Mac OS X 10.4.11). When I close the lid or when I manually try to make it sleep from the apple menu, it goes into sleep mode put only for 1 second and then shuts off (crashes). So instead of being able to wake up the computer, I have to boot it up from off.

I leave my Air on pretty much all the time, and put it to sleep while moving around etc. Sleeping it disconnect the Airport connection - which if very annoying. At a desk I've just been dimming the display all the way off in order to keep my connection.
However, I recently noticed that by setting a "sleep display" hot corner, my network connection is maintained.
I have 2 questions:
1) Is sleep display equivalent (functionally) to simply dimming the display all the way down?
2) Is there a way to either set up a shortcut to sleep the display (other than a hot corner) and/or set it so that only the DISPLAY sleeps after 'x' minutes?

I set the MBP to sleep in 10 min through the Energy Saver pref with the option to sleep the hdds. When it's about to sleep the screen dims, then turns black, then the sleep light comes on but does not blink no matter how long I leave it. The blinking only happens when I close the lid or when I select the Sleep option under the Apple logo. Is that normal behavior?

I have a macbook pro 13" early 2011 and I'm se as shown in the pictures (since i upgraded to os x yosemite) . It happens after display sleep or computer sleep on login not on boot up .I've noticed that i run out of ram when the problem appears (only 15MB RAM available out of 4GB), though i doesn't happen every time . I've talked to service and told me its either motherboard replacement or because the ram isn't enough (gpu shares with main ram) so maybe i should try upgrading ram. URL....

I have torrents going all the time. If the computer goes to sleep, the internet disconnects, so they stop. Display sleep wouldn't disconnect though. Is it OK to have computer sleep on "never" but keep display on "15 minutes"? I don't usually even leave the computer on overnight.

Recently I've started connecting my 2.5GHz Intel Core 2 Duo (pre-unibody) Macbook Pro 17" to an external monitor (via DVI). Â
Since then my computer goes into Safe Sleep instead of Sleep (it's plugged into power). Â
This is an annoyance I'd rather avoid because even if all programs relaunch:I have to wait for them to launch (longer)Programs like Excel seem to have been quit in an unorthodox fashion: when it starts back up I get an error notice that it was shutdown inappropriately & the doc which reopens is a rescued version of the doc I had open before the safe sleep.Â

i finally got my High Res Glossy MBP after 4 weeks of waiting...Everything works fine...and NO yellow tint issue...The only problem is 1 small dead pixel towards the bottom right of the screen...Will apple do an exchange on CTO machines with only 1 dead pixel?Is it even worth doing the exchange? After reading these forums i see that a lot of other users have been complaining about all types of problems...Yellow tint, wifi problems, over heating...etcshould I consider myself lucky? And just be happy that its only 1 small pixel?

In tiger you could easily disable safe sleep and remove the sleep image file but in Leopard this seems to have changed. Yes you can disable safe sleep & remove sleep image files but only temporarily. As soon as you restart or change energy settings back to default, leopard automatically reverts the safe sleep settings to default and starts creating an image file again
Is there no way to permanently disable/remove these?

I am running Mac Mini as a home server (turns out to be not a great idea, btw), and even though I set the preference to never sleep or shut down, it does go to sleep when there is no activity for long time. Since I am using it as home server, it should stay awake all the time or at least wake up from sleep when there is incoming ping from other computer, but it just goes to sleep.

Sleep seems to have stopped working all of a sudden on my recently upgraded iMac. The only thing I remember doing was repairing disk permissions and changing a few iChat preferences.
The console shows the following;
kernel Sleep failure code 0x00000000 0x11000000
A reboot does not clear the condition

iMac (24 inch Early 2009, 2.93 GHz Core 2 Duo, Lion 10.7.3) randomly goes sleep. No hot corners, never sleep setting.  It seems it goes to sleep more often when CPU is busy and graphic intensive jobs running (videos, gaming). I cleaned up air ways by vaccume, but it did not help.Â
Temp monitor showed
CPU 55C
power supply 95C
northbridge 89C
graphic processer goes up to 86C
when it went to sleep for no apparent reason./private/var/log/kernel.log says "Previous Sleep Cause: -100"

I'm an idiot, pleased to meet you.I had 2 external drives connected to my Macbook Pro, both had time machine back ups on...I meant to delete one of these but deleted the wrong one, and dragged it into Trash. On realising my mistake I tried to drag it back out of Trash, as you would normally but after "preparing to copy" for four hours it told me the drive was full...It's a 500gb drive, and the Time Machine back up is the only thing on it, so presumably it's just trying to copy itself when the back up is still present on the drive, albeit in the Trash.
