Computer hanging on closing lid and not going to sleep, indicator does not blink

i have a 1 month old Macbook Pro 13" i5 with 4Gb memory.
when i am closing the lid the computer is not going to sleep, hard drive continues to spin and power indicator does not blink and it remains solid.
on opening the lid again screen keep blank and does not show anything while i can hear spinning of hard drive. than i have to forcefully shut off the computer by pressing power key and than computer starts after that.
Apple support told me to press shift+control+option+power and than start computer, it fixed the problem only once and they told me to do it again when it comes again. but write now i am getting it everytime.

Hi guys -
First off make sure you don't have 'Wake for ethernet access...' enabled in System Preferences/Energy Saver/Options - I'd also run Disc Utility and repair your permissions as well. OS X requires 'maintenance routines' to be performed on a certain basis and you can use this free application to help you with that...Onyx.
Check the obvious as well - that you don't have any applications that might keep your Macbook awake ...some printer utilities do this for example.
After all this shut down and restart and hopefully things will be better - if not, there may be a chance that the mechanical parts that put your computer to sleep may be at fault ...and you'll need to visit an Apple dealer to verify this.
Hope some of this helps.

When I close my laptop lid and it goes to sleep so that I can use an external monitor, monitor does not turn on when I hit a key to start laptop

When I use my external monitor, I cannot get it to work after awakening my laptop using any key. My monitor won't light up although laptop keyboard is backlit showing that it has come out of sleep mode. Why does the monitor not get the signal from the laptop?

I still cannot figure out why it doesn't always work. All parameters were met and my bluetooth keyboard is set correctly to wake the computer. My keyboard becomes backlit, but my LG monitor does not pick up a video signal and is black and my laptop monitor is off. The only way I can get out is to hold on button on laptop until it shuts down and I can start up again. This happens on an intermittent basis. Sometimes it works and other times I get black screens. I need to know if I can use command F1 to get the laptop to detect the display or is their another key combination to send the signal to the external monitor when I can't see anything because I hate to do a hard shut down to get out of this mode! Please advise!

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?

How can I make my computer only recognize my network and not that of one of my neighbors?

How can I make my computer only recognize my network and not that of one of my neighbors? This is for when I am at home, and everytime the computer goes to sleep it essentially loses the connection, only to pick up my neighbors network when it is awaken.
I am on Comcast (Xfinity) Highspeed Cable wireless modem/router
Thanks in advance!

You can make your network the preferred network.

Hmm... I've had this macbook for a while now (?? a year maybe ??) and about 2 months ago I started having this exact issue, close lid to sleep returning it would not wake and a hard reset (hold power for 5+ seconds) is required.
I too discovered such links as this and also the older (also unanswered):
http://discussions.info.apple.com/message.jspa?messageID=8690782
But as others have said there doesn't appear to be a solution?
RESET THE SMC (http://support.apple.com/kb/HT3964) does appear to work, however the issue returns again after a few days or weeks... I cannot find anything that guarantees to return the issue it just starts happening again after a while.
The battery appears to be in okay condition, although I think it might run down a little faster now days than when I first bought it, but I assume this is to be expected.
I also had suffered from what sounds like an issue with wifi weirdness - signal would drop to 0% suddenly, no longer "see" the wifi hub that it has been using forever (although it still, randomly, sees other nearby hubs) for no apparent reason, and that kind of thing - all these times the only solutions that have worked have been to stuff around with the wifi hub turing off extas, flipping from "Auto" to a specific Number (1 to 13) and turning on (OR OFF!) Mixed B/G to just B OR G... very strange... and random.
The only things I've changed recently are, upgraded to snow leopard (from leopard) and got an external display. But I cannot say if the incidents coincided or not, as I didn't realise the sleep/wake issue was an issue for a while, as the first few times I just thougth "Oh, something weirds happened... Reset..." and didnt' really think too much about it until it happened for the 3rd or 4th time and I could see there was a pattern...
The external monitor via minidisplay port adaptor i got from teh apple store.
I don't use it with the machine closed or external keyboard/mouse, although I've heard you can do this, I use the monitor as a secondary display when I'm at the desk, the rest of the time I just use it as I have always done.
I would love to see a solution to this, I guess I could try warranty, but I dunno if the issue is warranty "level"...?

IPhone hangs at Apple logo, and not recognized by pc

I've got the weirdest problem. My iPhone 3G is bricked. It will go on, display the apple logo, then display the round "budy" symbol and then hangs for 10 minutes and then it resets itself and starts over.
I tried to hook it up to my PC but it is not recognized, not by my PC nor by iTunes. The iPhone will charge when connected to the PC, but it's just not transmitting data.
I can get the iPhone in recovery mode. I turn on iTunes, then I hold the home button, slide the connector in while keeping the hold button down, and then the itunes logo with the cable and the arrow shows up. iTunes however does not recognize it. It is not shown in device manager either.
I can also get it into DFU (i think). I turn on iTunes. The phone is off, and connected via USB. I hold the power button for 3 seconds (it boots after 1), then press the hold button for 10 seconds (it goes off after 7) and then release the power button while holding the hold button. The iPhone is now in DFU mode (i think, as it does not respond to anything but a forced shutwodn with pwr+hold). Still the PC and iTunes do not recognize any device is connected. As if it is not even there, but the iPhone is being charged.
I can't restore it now, and I don't know what else I can try. Any suggestions?

You've done most everything there is to do, on that computer. Try it on another computer before regulating it to paperweight status. It's probably the hardware, but I've had them surprise me a time or two

Closing Lid When Not In Use

This may be a silly question, but I have never seen anyone inquire about this.
I usually leave my Mac Book open while sleeping and rarely close the lid, as it is used more as a desktop rather than a portable. Is it wiser to close the lid when not in use to protect from dust or is it wiser to leave open to prevent any wear and tear of frequently closing the lid?
MacBook Mac OS X (10.4.7)

i think you should always close it because it prevents dust and it was made to open and close i close mine when moing from room to room and no problems i think the people at apple know that people close LAPTOPS and they would build a strong hinge

TS3992 Am trying to do an initial backup however after 4 or 5 hours it keeps dropping wifi.The computer is next to it and not dropping out.Thanks

I once again am trying to do initial backup after correcting from a previos email adress.After 4 to 5 hours it keeps dropping the wifi and does not start again automaticly.Computer is also on wifi and seems ok.Tho longer its on the more often it does it.Thanks

The backup file size is 1.67 TB.*
That's across the internal bus of a 2009 quad-core Mac Pro - which is pretty fast.
Copying an hour's worth of MPEG-2 HD takes about a minute.
I do a fresh backup from scratch about once a year, and the last time it finished over night.
This time the first Time Machine backup is only about 1/5 complete after many days, and Activity Monitor shows essentially no use of disk drives or of CPU. And in the first note I pointed out what is gleaned by using Terminal to execute the UNIX ps command. The priority of the running Time Machine process looks incorrect to me.
I could be wrong, but I think the problem is process priority, not file size.
I am unable to set priority to 0 or a negative number. Can someone straighten me out on how to do that?
[*The machine has four 1.5 TB disk drives in it plus lots of memory. Two of the physical drives are configured as one 3 TB backup drive (RAID concatanated).]

Express Card Slot - freezes up my MBP when connected and it goes to sleep

When I have my express aircard in the slot - whether it is connected to the Internet or not - and I try to put it in sleep mode or it automatically goes to sleep mode, it completely freezes my computer and I have to force quit in order to use my computer again. If I take the card out before putting it into sleep mode there are no issues; however, I don't always remember to do so. Anyone else having this issue?

" ... Anyone else having this issue?"
Sort of. Not duplicable: I can tie the MBP into knots by simultaneous d/ls on like 3 open browsers with multiple tabs too. When I don't get a freeze in my browsers, or in my AT&T GlobeTrotter Connect app, I can leave it inserted and close the lid for sleep (which disconnects the modem anyway), and wake normally (but disconnected). I usually try to remember to take out the aircard before sleep; since it does protrude, and might get bumped!
When you say: " ... it completely freezes my computer and I have to force quit in order to use my computer again ..." I'm not thinking that having to just force quit your aircard app is a total freeze. Try getting the Grey curtain of Death, for that! But I know what you mean. I have that same light freeze, and must apple-option-escape three finger salute, force quit the aircard app, just to get the Finder to work. Then I must double-restart with PRAM upchuck for luck, to be able to launch the aircard app again, else it just sits there and locks up again ... And it usually takes me like three tries to connect, at busier times of the day. I am grateful to have the aircard, since it is my only access, due to extreme rural-ness. Kinda like Alaska, only warmer?
You got AT&T or Verizon? My only reception is AT&T, and luckily I got the Option GTMax Express aircard, instead of the Novotel USB dongle. The Option Express 34 has the port for an external antenna, which I need, and used to need even for voice cell phone ... and the USB dongle does not have that port. The little flip-up antennas on either do not give much gain yah. Fine for city life ...
Reception gets better as more towers are built, but that comes with population growth usually. Speed improves as Edge gets upgraded to GSM ... soon? I am getting like 16K d/l when lucky, on Edge only ... My AT&T took $25 M from NipponTel this year to upgrade to GSM, so NT can soak the Asian tourists here on vacation with roaming, etc. They are used to very high speeds d/l and were dying with Edge only ...

G5 startsup one in five times and then goes to sleep

Hi - I have late 2004 dual G5. Recently it completely boots up and shortly after, puts itself to sleep even while I am working on it. Then it sometimes does not turn at all and just has a black screen.
I have done everything I can think of. Reset the PMU numerous times, done an openfirmware boot - but after reset it doesn't turn back on. Tried to boot from Install disk, doesn't work. Tried to reset PRAM - doesn't work. I have reseated the RAM and now it soemtimes turns on with half a balck screen and the rest white and then nothing happens.
I have unplugged it over night, held the power button down 15 seconds unplugged, etc...nothing works. It does not chime and if I remember correctly has been working without the chime for awhile.
If I leave it unplugged long enough, it eventually turns on and then I can look in the console log (exit on exit code:6) but I cannot run the disk utility or do much of anything else.
My G5 is like an old friend and I really don't want to lose her. Any advice would be greatly appreciated. Thanks

Thanks - I don't think it is the battery as I did replace it recently. I have tried to start up in openfirmware and never get past "cataloging file". I have tried Safe mode and can't get past the grey screen and I have tried C on startp - nothing. And finally, I have tried holding down option on startup and get to the right screen but it freezes when it gets to the watch. Guess I better give up and bring it to the shop and see if it is worth fixing.
It still turns on completely and goes through the whole start up process - it is just that it then goes into sleep mode. I can wake it 2 or 3 times and then I only get a black screen. I have to unplug the power from the back of the computer and let it sit at least 15 minutes for it to go through the startup process again.

Since update download monitor shows "No Signal" and "Monitor Going to Sleep" over and over

I have an HP w2072a Monitor and a Pavillion p7-1436s computer. I run Windows 8. Since downloading an update yesterday, I cannot get my monitor to work. I have unplugged it, plugged it in, tried another monitor, tried another cable, turned the computer off and on several times, played with the sleep button, tried all the buttons on the monitor--nothing works. If I hit the "On" button, the light turns to blue briefly, I get the screen showing "No signal" then "Monitor Going to Sleep" comes up and the light turns amber---over and over again. Could this be related to the update I received? I think the update said it was setting a restore point, but with no monitor, I am stuck!

Hi dianthus,
Sorry to hear about the issue after doing the update. Do you recall what the update was for? I have included a document regarding your issue.

I want to close the lid without it going to sleep

I want to close the lid of my MacBook without it going to sleep so i can leave things going overnight e.g. moving large files. Does anyone know how to do this? I dont want leave the lid open as it will burn the screen out.
Please help.

Why don't you have your screen set to power off after a certain amount of time? System Preferences->Energy Saver. There are 3rd party utilites that will allow you to disable sleep when closing the lid.....but if your only concern is "burning out" your screen....seems kind of pointless to me when you can just have the display go to sleep.

Late 2012 mac mini display signal drops while booting and monitor goes to sleep

I have a new Late 2012 Mac Mini. I have had it for a week, what just started happening is that during restart, the video signal drops and my monitor goes to sleep. I then have to toggle through the input options on the monitor and the video signal is detected again and the monitor wakes up.
Here is what I see - If i shut down and then power back up, I get the grey screen, then the apple logo, then the little status circle spins for a few cycles then stops and then the screen goes black and the monitor says signal lost and then 5 seconds later goes to sleep.
It is possible it is my monitor but, I haven't had any issues with it and i only drops the signal like that during a reboot.

Welcome to the family. Search this forum for the main thread for this problem titled: "mac mini 2012 video blinking out".

MDD boots and then goes to sleep immediately

have a dual gig MDD and suddenly the thing just started going to sleep or powering down right after booting up.
i've taken everything out and unplugged eveything to bring it back to it's intial state; i've zapped pram; i've pulled the battery; nothing seems to help.
with the hardware cd as the boot, i get the following
Invalid memory access at %SRR0: 00034870 %SRR1: 00003030
USB Setup Error: 40140000 400001
bad Bus info CRC-16
Apple PowerMac3,6 4.4.8f2 BootROM built on 09/30/02 at 10:24:31
which made me think it might be one of the RAM sticks. so i've puleld them, tried with just one and still nothing, swapped sticks, no go. with the cd in, when it goes to sleep, upon waking i get:
Decrementer exception at %SRR0: 056106dc %SRR1: 00003030
at first i thought it might be the boor drive but since booting from the CD still causes the problem, my guess is the MoBo.
if anyone can help me out, maybe something i've missed so i dont have to spend $500 on a new MoBo, i would be very grateful

An overheating proc can definitely make the thing go to sleep. But I don't know what would make the fan power stop working. I believe that's controlled by the PMU, but you've reset that.
I've seen some pretty strange PMU-related behavior, so nothing would really surprise me. Just today, I found that my firewire ports weren't working - they'd power peripherals, but I couldn't get either of my FW drives to show on the desktop. I booted to two different internal drives and had the same problem. I reset the PRAM, NVRAM, and the PMU and no improvement. Finally, I unplugged the PRAM battery, hit the PMU reset button, and let it sit an hour before plugging it all in again and viola - firewire worked!
It might seem redundant, but if I were in your shoes, I'd unplug that PRAM battery again, hit the reset button, leave it out for a couple of hours, and then plug it all in again to be absolutely sure. Also, be sure never to press the PMU button twice between starts.
