Long Delay When Putting MacBook in Sleep Mode

My 2 year old MacBook has recently started to take quite a bit of time to go into sleep mode. If I select sleep under the apple menu, it takes about 45-50 seconds for the screen to turn off. I can hear the computer running during this time - when the sound stops, the screen goes off and the sleep light begins blinking. In the past, my screen would go off immediately after selecting sleep mode. If I close it to launch it into sleep mode, the same thing happens - the sleep light doesn't start blinking for 45-50 seconds. I checked the Activity Monitor and nothing else is running that could cause the delay. Any thoughts?

You should check the "Disk Activity" section of the Activity Monitor to see if there is a lot of disk activity occurring. Most likely, the delay is it copying the RAM contents to the hard drive. It may be otherwise but this would be my best guess.

What do I do when my MacBook Air (refirbished) sometimes turns on and sometimes does not when it is in sleep mode and when I turn it off?

I got this refirbished MacBook Air sometime in the last week or two. Now lately, when I turn it off or put it in sleep mode, then try to turn it on; it will take a long while to turn on or it will turn on normally. Can anyone help me?

Try a SMC reset.

Every time I turn the computer off or put it in sleep mode... when I come back my wallpaper is gone. I have to keep going to my pics and getting it back. Does anyone know why this keeps happening??

Are you choosing it from one of these folders (in my screenshot) or you can also put that picture into the correct folder. The path is:
HD > Library > Desktop Pictures
If you add it to the folder manually, please restart your computer.
And yes, letting it sleep is a good idea, or else the startup disk will spin and the screen may suffer from image persistence if you leave a window or image parked in the same spot too long, so the screensave is a good idea.

OSX 10.9.1 macbook pro 13 retina - wifi does not reconnect automatically when waking up from sleep mode since I have a Bluetooth apple magicmouse

Hello,
My config is OSX 10.9.1 new macbook pro 13 retina (2014).
The wifi does not reconnect automatically when waking up from sleep mode since I have a Bluetooth apple magicmouse.
It was not the case before I bought the BT mouse.
Is this problem between Wifi and bluetooth coming from the OS?
Is there a fix already available or scheduled?
Thanks

Hello alexandrefromfrance
Check the Symptom: The network connection drops unexpectedly section for steps on what to do when your MacBook Pro does not connect after waking from sleep. I have also quoted the section on troubleshooting the issue as well.

Why is my Mac Air still hot when I put then in sleeping mode?

Hi,I wonder why is my Mac Air still hot when I put then in sleeping mode?

I just looked in my history - can't find the link. I was googling for about 15 minutes out of curiousity before.. just researched more though. I think its an integrated circuit (the IC part) that is a combination of both analog and digital die sensor readings:
"Many embedded systems need to read sensors that produce analog signals. Since processors are built to interpret and process digital data, i.e. 1s and 0s, they are not able to do anything with the analog signals that may be sent to it by a device. So the analog to digital converter is used to convert the incoming data into a form that the processor can recognize."
Analog Die - Analog : 125
CPU Die - Digital Core : 129
x19 controller IC: 264
125 + 129 = 254....close....
Thank you for asking! You spurred further investigation
And your computer temperatures look absolutely fine. I wouldn't worry at all.

What do I do when my mac won't start up? I put it in sleep mode after installing the latest OS Lion update and now it won't open up.

Near new mac pro retina, updated OS last night, re-started, finished my work & put it into sleep mode. On power, & hooked up to Thunderbolt screen. Got up this morning and it won't boot up. Is there anything I can do myself, or is this a shop problem?

Sounds like a #1 SMC or #2 PRAM reset is in order.

No WiFi when coming out of Sleep mode

I have searched about a dozen pages looking for a solution to this and have found nothing (or at least my eyes are crossing too much to go through the other 20+ pages) But...
Randomly, after using WiFi on my MacBook, and closing the lid to put the computer to sleep, sometimes it won't connect to the WiFi router upon waking back up. it happens on both my home and work routers (both of different makes), and will not connect unless I physically reset the router (something I can not always do and is very inconvenient) Restarting the computer will not fix the problem either, nor will turning the Airport, and then back on to reset that... nothing will make it connect unless the routers are reset, and THEN I try to connect it goes.
Does anyone else get this? It it a known bug? Is there a way to kick the WiFi back into place when this happens without having to reset the routers?
Any advice, or help is greatly appreciated.
Thank you.

Yes!! I am seeing the same problem.
Sorry no answers yet but can describe what I've seen:
Got a new MacBook (10.5.2) last week, got it connected to my home wifi network, but after putting it into sleep mode it would loose the conection.
Managed to get it connected again by removing security from the router (as a temporary experiment). But with it switched on it would not connect.
The error message is "Connection Timeout", although I have occasionally (normally on the first attempt after a reboot) got "Invalid Password".
The router is a Netgear DG834PN, and I have a number of devices attached without a problem, including Dell laptop running XP, iPhone, Wii.
Got to the point where I tried changing the SSID on my router and tried a different type of security (first time I used WEP, second time WPA Personal). Worked great until the laptop went to sleep (for long enough to loose the connection). After waking would not reconnect.
Tried restaring lapttop, unplugging router, changing router security back to WEP. Can see the router, but cannot connect.
Speculating here, it's as if the macbook is storing the wifi password for the router incorrectly - or retrieving it incorrectly. Unfortunately I don't know enough about Macs to poke around under the bonnet, and the Wifi options are a little light.
Please can anyone help??
This is my first MAC and I really want to love it
cheers,
Sam.

Need help - wifi gets disconnected when it goes to sleep mode - iOS 6, iPhone 5, WPA Enterprise

Hi, I have read a lot of discussions regarding wifi gets disconnected when it goes to sleep mode on iOS 6, mainly on iPhone 5.
Here is my configuration and it just keeps disconnecting wifi connection once it goes to sleep mode
iOS 6
iPhone 5 white
Purchased on Nov 3
Work wifi config: WPA Enterprise
I tried to manual add the wifi but it did not work. I tried all except for upgrade to iOS 6.0.1. I had a call to Apple Support and the guy told me I could not trust everything i read from here (well, how dare he is!!!). But I did all I could think of, and read from here.
I am with ATT and I do not have a receiption at all at work. I have to turn it to airplane mode, and use the wifi connection. I put my iPhone 4 with iOS 5.0 side-by-side to compare. My iPhone with iOS 5.0 DOES NOT disconnect the wifi connection when it goes to sleep mode; but of course, we all know, iPhone 5 with iOS 6.0 does
Any helps would be so much appreaticated. I am considering to return the phone to apple store, and cancel my 2 yrs extended contract with ATT. I might think to get another one once they have the issue fixed. It is no point to have an expensive paper-weight at work while I can't use the celluare nor wifi connection.
Thanks again,

Hi ChrisJ4203
I have tested it at home wifi tonight. My phone and my wife's iphone (both iPhone 5 with iOS 6.0) do the same.
With cellular data on (aka airplane mode OFF) with WIFI ON
Wifi icon replaced by ATT's LTE icon once the phone was waken up from sleep mode; but within 2 secs, the wifi connection got reconnected again.
With cellular data OFF (aka airplane mode ON) with WIFI ON
WIFI icon disappeared from the top bar after both phones were waken up from sleep mode. It took a while to reconnect to the wifi network (more than 10 seconds).
On a separate note, after i rebooted my phone, i can see it does "searching" the ATT's signal, then it shows "No Service", then next second, it shows ATT with full bars and LTE icon.
My question is, i have never noticed the "No Service" showing up from my iPhone 4. The "No Service" shows up on my wife's phone too. When I first got her phone and was doing the installation, I had noticed the cell signal dropped from full bars to no service, then within few seconds, it went back up. I have not had time to test on her phone again, but it is something I will be monitoring for. I wonder if anyone has similar experience like this.
anyhow, any feedback on how to fix the wifi got disconnected while in sleep mode would be very helpful.
thanks,

Is it best to turn off your computer or put it in sleep mode.

Is it best to turn off your computer or put it in sleep mode.
I have a MAC Book Pro
2.4 GHz Intel Core 2 Duo

Well. Apple recommends to put the Mac into sleep mode if you are going to use your Mac after a short period of time, and they only recommend to turn it off when you are not going to use the computer for several days.
In sleep mode, your Mac consumes only a small battery capacity, so it's worth to put it in sleep mode. Also, it's much faster than turning the computer on every time you want to use the Mac

One day i was just flipping through my ipod i put it on sleep mode then next time i opened it without me doing anything it gave me an option of ''slide to power off'' i pressed cancel then it automatically went back to sleep mode it is still happening

One day i was just flipping through my ipod i put it on sleep mode then next time i opened it without me doing anything it gave me an option of ''slide to power off'' i pressed cancel then it automatically went back to sleep mode it is still happening my ipod is jailbroken and i didnt fiddle with the settings.. please help.

If it is jailbroken, we are not allowed to help you with that here. You'll need to seek out other sources of help. The jailbreaking could potentially be part of the problem, for all I know.
BTW, just a pointer... punctuation is your friend! Your post was very difficult to read without any. Many people will simply stop reading and click the "back" button when encountering something like that, which limits availability of help to you.

[SOLVED] Automatically put HDD to sleep mode after start

Hi everyone.
I use a secondary HDD for backups. It's plugged to my computer permanently but actually it is needed for a few seconds per day. A backup script automatically shuts it down after backing up with `hdparm -Y` to save a power and reduce a noise. And I want to shut down an HDD also every time after the system is started.
I tryed two ways to implement this.
1. Udev rule that runs `hdparm -Y` for the device identified by ID_SERIAL_SHORT attribute.
2. Following systemd service:
[Unit]
Description=Put HDD to sleep mode immediately
After=systemd-udev-trigger.service
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/sbin/hdparm -Y /dev/disk/by-id/ata-SAMSUNG_SP2514N_S08BJ1HL210777
[Install]
WantedBy=sysinit.target
Both methods actually run hdparm, but state of the HDD is active after login (I check it with hdparm -C). It looks like something in systemd "touches" the hard drive and wakes it up back. And I can't find what may access the secondary HDD after udev rules are processed.
What is correct way to solve the issue?
Thanks.

Well, I think you would need to determine everything that might be polling your drives during the boot process, which might be a pretty big task. Then use that information to determine either when udev should run that command, and use the lexicographically ordered rules to try finding just the right spot (and even then it might just come down to a race). Or you can use the gathered info to try and make systemd's service dependencies do the work for you. Either way, I would honestly rather just use a timer.

WIFI slow to reconnect when phone awakes from sleep mode

Today, I updated my LG G3 to Android Lollipop. I have WIFI set to turn off when in sleep mode (unless device plugged in). Now when the phone comes out of sleep mode, it takes up to a minute before the WIFI connection is reestablished. With the previous version of the OS, WIFI reconnected immediately after awakening from sleep mode.
Has this problem been reported to Google? I have not found a way to report bugs directly to Google as a user.
Thanks,
Tim

Joel, thanks for your reply. I've followed your instructions, and the problem persists. I assume by reset, you mean reset to factory settings. No. It has been rebooted, and powered off/on several times since the OS update. I have no idea whether there are any apps that use WIFI only. How would I know what each app may require?
Since this happened immediately after the OS update, the logical conclusion is that the update caused this behavior. In my 45 years as a software engineer, I can say this is the most likely cause.
Now, here are two more observations. When I first power the LG G3 up, the WIFI connection is made immediately; before I even unlock the device. So, we know the OS is quick to establish connections upon power up. It is only when coming out of sleep mode that the WIFI connection is slow to be reestablished, taking about a minute as opposed to immediately with the prior OS version.
The second observation is that with my wife's Samsung Note 4, which was updated to lollipop several weeks ago, I do not see this delayed WIFI connection after being awakened from sleep mode. With the Note 4, the connection is reestablished immediately with lollipop as with the prior OS version.
Considering the difference in behavior between the Note 4 and the G3, I would conclude that LG made a firmware change for lollipop which is causing the delay, or LG didn't make a necessary firmware change for lollipop which is causing the delay. At this point, I would say this is an LG G3 problem. It should be easily reproduced. Under the advanced WIFI settings, the setting "Keep WI-FI on when screen is off" should be set to either "Only when plugged in" or "No".
Thanks again for your help.

Imac keeps putting itself into Sleep Mode.

This morning my Imac has put itself into sleep mode twice within an hour - losing everything I was working on. It just goes black and then loads the log in screen.
I've never had this issue before, it's not over heating (not sure if that could be a problem) it's not full up, it's not lagging it's just this problem.
I really cannot afford the time to take my Imac into the store for repair unless ofcourse it's really needed. Can someone help please?
Thank you,

Hi Tori,
Unfortunately I'm unable to help, but I want to add that I had exactly the same problem this morning (Jan 13, 2013)! It was putting itself into sleep mode twice within 5 minutes.
In contrast to TorkiClarkson, the fan of my iMac was blowing hard, but that happened a lot the last months without falling into sleep mode. Actually I'm a bit afraid I've got a heating problem since my warranty of 1 year has experienced..
Hope someone has valuable information for TorkiClarkson and me.
Thanks.

Disconnected from ANY chat program when I go into sleep mode

I am using an airport express connection with road runner. When my computer goes into sleep mode, any chat program I am using is disconnected -- this happens with AIM, iChat, and Netscape Navigator's chat screen. As soon as I move my mouse, or touch the keyboard, and go active, AIM automatically reconnects. Any ideas on how I can remain signed into a chat service when I go into sleep mode?

In sleep mode your mac only keeps the data in the RAM. all other things will be turned off, so that it´s impossible to stay online with the chat applications.

Ever since I got the new update 5.1 my iPod's been dying faster. It used to last for at least 3 hours, now it won't even last one hour and dies for no reason(even when it's in sleep mode, and not in use) What's wrong with it? Is it the update? lagging too
