Powerbook keeps putting itself to sleep

My powerbook goes through phases where it puts itself to sleep over and over again. I may get a few seconds to maybe a minute before it goes back to sleep. I'll be working or using the trackpad or whatever and it will do it anyways. I usually have to reboot in order to get it to fix itself, but sometimes it starts sleeping before I can even log in. This problem happens both with the power adapter plugged in and when running on battery. The battery is fully charged. My power and energy saver settings are normal, it shouldn't be going to sleep every 2 seconds. I read some stuff about resetting pram, tried it, didn't do anything (could I have not reset the pram correctly?) Also, I read something about resetting PMU (I think that's what it's called), followed the steps, and so far it hasn't happened again but I'm not too hopeful. This is supposedly a known powerbook problem - anybody have a solution?

Hi, jmenking. I've read every entry on these Titanium Powerbook forums for almost two years, and I don't recall ever seeing this problem reported here before, so I question whether it's really a "known Powerbook problem", at least with the Titanium models. Is yours Titanium (with most of its ports on the back panel betwen the two hinges) or Aluminum (most ports on the side panels)?
It sounds as though there may be a problem with the reed switch built into the latch assembly inside your display bezel, which is supposed to put the Powerbook to sleep when you close the display. The switch is normally activated by a strong magnet inside the display latch button, but it sounds as though your switch is either being activated when it shouldn't by some other magnet in its near vicinity (this doesn't seem likely unless you have magnets strewn about your workspace), or is broken, and closes the circuit when it shouldn't. I would suggest taking your Powerbook to an Apple dealership for a look-over or calling one or more of the shops listed below for advice. If the switch is bad, the repair is definitely a job for a technician — it's not a do-it-yourself proposition at all.

Really need some help here. My G5 keeps putting itself to sleep and more..

Just out of the blue my mac doesn't turn on. I turned it on a few more times and it still wouldn'tt power up, my screen was just not recognizing anything. So I open up my mac unplug everything, than turn it back on and it works again. But the fan is very loud, I hear grinding noises every now and than, and the weirdest thing is it would not power up unless I took the cover off my mac and removed the plastic bay that protects the inside from dust.
Now it keeps putting itself to sleep. Over and over it's so frustrating.
I'm very concerned here, is this a hard drive problem? I even formated my hard drive, but that did nothing.
What is going on here?

Have you checked the PRAM battery?
I would check it first. When mine went, I had no response from my Mac at all; just a light on my power button; absolutely no boot at all.
Check out things in Texas Mac Man's Battery, PRAM, PMU tutorial on the subject. His tutorial is a little dated (don't believe it even mentions G5's) but the info in it, except SMU not being included, still applies.
I believe this is the battery for a Late 2005 G5 2.5 dual. Yours is near the age it should be replaced.

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.

Imac keeps putting itself to sleep

In the middle of doing something my Imac will just go off. I have to press the power button for it to wake from sleep. What is wrong with it?
For example, I am working on a text file,etc.and it just goes to sleep!
Thanks, PLEASE HELP

Your POwer Supply unit may be failing, how long does it stay awake and do the fans go on high?
Try resetting the PMU by shutting down, removing all peripherals as well as the power cord.
Let it sit for about 15 seconds then reconnect the power cord and restart.

IBook puts itself to sleep and/or shuts down

My gf's iBook G4 (14-inch Early 2004) puts itself to sleep at random. No amount of pressing keys will wake it up, only pressing and holding the power button to shut it off completely, then rebooting, will get it back. Sometimes it shuts itself off completely at random. When starting it back up, it often refuses to boot all the way: will start to display the grey screen, then turn itself off. Resetting the PMU seemed to help for about an hour, then the same problems started again and now I can't get it to boot up at all. It won't even boot up into target disk mode so I can rescue her data with my Powerbook, nor will it boot from CD! Resetting the PRAM had no effect. She's understandably quite upset and thinking of getting a new computer. Is there any less expensive fix for this? Any help would be greatly appreciated.
Thank you.
[edit]
By the way, I've read the other threads here describing similar difficulties, but I doubt the problem is the GPU needing to be reballed. The machine won't start up at all, rather than being started but having a black screen.
[Additional info:] I had noticed during it's last successful boot that the battery was dead in spite of the power cord having been plugged in to a working socket for days (and yes I'm sure the socket works). I've also tried with the power cord for my Powerbook with no success, and verified that her power cord works by plugging it into my Powerbook. This is what lead me to try resetting the PMU, but as I said that didn't work. Could it be that the PMU itself needs out-right replacing? If that's possible, is it possible to do so without replacing the entire logic board?

Joel,
I don't think leaving it on all the time was much of a factor other than wearing the battery down faster which, according to Apple, has a approximately a 1-2 year life. Mine went before the 2 years was up and it's $129 to replace it.
Using it with the battery while it's plugged in without air circulation or a laptop cooler might be some extra wear and tear. Mine runs the hottest during that time, but if I unplug it and just use the battery, it cools way down. I'm interested in which iBook your GF has because a friend out of town has been reporting the same problem and I figured she didn't know it was sleeping. Hers is a 14" 1.0ghz I believe.
The case is supposed to be really strong, made out of bullet proof material, so the Apple sales rep told me, and it can survive an accidental minimal drop, unlike the PBs. I haven't tested that, but another friend dropped her 12" the other day, while it was open, and it looks like it just loosened the video cable. I haven't opened it yet to find out.
Is there any chance that the energy control panel was turning it off? Mine turns on EVERY morning at 3:10am even though I have unchecked the box for it to do that. It came that way from Apple and I thought it was so it could run the maintenance tools. I have no idea why it still turns on, but it's not a (future) problem that I know of.

MacBook Pro mid 2010 putting itself to sleep and restarting on wake-up?

My mid 2010 MacBook Pro has recently started having a lot of problems. It will put itself to sleep whilst I am working on it, and when I try tp wake it up it restarts showing a message saying 'Your computer restarted because of a problem. Press any key to continue..' however it doesn't tell me what the problem is. This can happen every 5 minutes or once an hour but it is becoming very irritating. I have previously done a PRAM and SMC restart, they made no difference. I can't think of any recent programmes I have installed to cause this problem, other than updating to mountain lion 10.8.5. Im not very computer savvy either, so understanding much of what is online is not easy.

You have the MacBookPro6,2, the Edsel of Macs. It may be covered by this program:
MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers may not detect the fault. There is a specific test for this issue.
Print the first page of the panic report, and the support page linked above, and bring them with you.
Note that the replacement program only applies within three years of purchase. If you wait beyond that date, Apple may refuse the service. In that case, you'll be quoted a price of about $300 (in the U.S.) for a depot repair. The model was discontinued in February 2011, so the replacement program will be ending quite soon.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Sometimes the replacement part is also defective, so be prepared for that possibility.
If it's too late for your unit to be repaired under the program, and you don't want to pay for a new logic board, you may be able to stop the panics by disabling automatic graphics switching.
*An SSD doesn't need to be zeroed.

HT3964 IMac, Mountain Lion- overheating and putting itself to sleep when it gets too hot.

I've tried re-setting the SMC on my intel core i5-2.66 GHz Imac 27" to stop the fan from running all the time. It started when I first upgraded to snow lepeard. I thought maybe Moutnain Lion would help this issue, but now it's overheating and putting itself to sleep when it gets too hot. Any suggestions? This happens after about two hours of working. Using Adobe Suite only and still overheats.

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
First off, there is nothing wrong with the fans running all of the time, they are the Macs cooling system and they would not run under normal conditions if the Mac didn't need them to run. So unless they are racing and your Mac sounds like a jet ready for take off, the fans are just doing their job.
That said, I think Apple's idea of how mcuh and how fast they should run does not always match the iMac's real needs. I, like many others, use SMC Fan Control and I set the speed at which my Mac's fans run.

PB puts itself to sleep when in use

The powerbook will put itslef to sleep with no warning. I will be working as normal on my computer and all of a sudden the computer diplay will go black, and the sleep light will begin to blink. I am not certain if the hardrive also goes to sleep, but im pretty sure it does. Sometimes it will happen as soon as I rewake it, and in most cases this ends in the computer freezing and forcing me to remove the battery and AC adapter to simply restart it.
I have tried reseting the power management unit, removing external devices, and instructing the computer to not sleep at all. It seems to happen at random, for instance, atm, it seems to be working fine, but it could go to sleep at any second.

I have had the worst time with my PB for about a month now. It all began when my hard drive crashed. I Replaced the HD.
Reloaded and updated the OS and all software.
Then, after about a week of everything running like it should, I began to have problems brought on by encrypting my data. My PB began to freeze. I spent about - and I'm not exaggerating - 3 1/2 hours on the phone with Apple Care. Finally had to zero out my hard drive and - once again - reload EVERYTHING.
Everthing was fine for about a week and then, out of the blue, my PB would go into sleep mode - while I was typing.
I spent another 2 hours on the phone with Apple Care. Finally had to zero out my hard drive and reload everything - AGAIN!!!!!!!!
Imagine the frustration when - after I reloaded everything which takes at least 3-4 hours (after downloading upgrades and all) within 15 minutes it went back into sleep mode while I was typing!!!
At this point I was just about ready to throw it out the window.
Instead, I brought it to the Genius Bar.
They took it in and replaced the mother board (the error log stated something about a printer error though it wasn't on line with the printer).
I got the PB back the next morning and began to check my email when - guess what happens - yep, it went to sleep while I was typing!!!
Each time it went to sleep I was able to wake it up after about 10 seconds by pressing a key. It would stay on for about 7 - 10 seconds before it would die again. After going through this cycle about 10 times it wouldn't wake up until I removed the battery. When I turned it on this last time I went immediately to the error log to see what was happening and this time it said "excessive temperature".
Okay, so I went back to the Genius bar (amazingly, no blood was shed), and this time they sent it somewhere to be fixed.
I'm waiting for it to come back. Though with all the problems I've been having with it I'm actually quite afraid of getting it back and having this or something else happen.
I've got to say - through all this - the only reason I'm still sane is that everyone that has assisted me, whether on the phone with Apple Care or at the Genius Bar, has been absolutely fantastic! I love those guys! And, I love my PowerBook - I just want it back - the way it was - before all this started happening!
I've been doing a lot of searching regarding this problem and - although Apple techs seem to have never heard of this problem before(???) - it has been happening to A LOT of people that have PowerBook G4's 15" and 17" built during 2005. It has to do with the TrackPad Sensor going haywire and the Topcase must be replaced - perhaps the motherboard as well.
If you speak with an AppleCare tech tell him to read this: http://communitymx.com/search.cfm?searchtype=Basic&searchbox=PowerBook+Sleep&sub mit2=Search&shortLong=1&searchinside=0
GOOD LUCK!

Computer does not put itself to sleep when used in lid-closed mode

Hi. I'm having a small problem when using my macbook pro with the LED display, lid closed and with external keyboard and mouse. If I leave the computer unattended, the display goes to sleep at the time specified in system settings under energy saver. The computer, however, does not go to sleep - the white power indicator remains solid and noises for new email etc can still be heard.
I should probably just try to remember to put it to sleep manually but I keep forgetting. Does anybody know what settings I need to adjust?

I tried cycling the old battery many times, and the computer would still shut down unexpectedly instead of going to sleep when it ran out of power. I got a free replacement from the supplier [http://myworld.ebay.com/cbkusaelectronics>, but I have cycled this new battery twice now, and it still does not go to sleep when it runs out of power. The capacity of the battery is fine (4.9 Ah), and the timing calibration seems fine as well. I have two older batteries from NewerTech and they allow sleep every time, so I think my computer is fine. Can anyone enlighten me about the cause of this problem? Does my battery lack some 'sleep battery' cell in it for use after the other 4 cells discharge? Or does my battery lack a chip that communicates with the computer? Is there any hope of getting this battery to support sleep when discharged?
Has anyone else seen this problem consistently in a brand of battery? Does anyone have a recommendation for a cheaper battery that does not exhibit this problem? I have been happy with NewerTech, but they cost over $130.
(I only paid $44 plus $10 shipping, so I probably got what I paid for. It is maybe still worth it to have a high capacity battery for such a low cost, but I can't rely upon it in those last few minutes or I may lose work.)

Emergency overtemp signal? powerbooking putting itself to sleep

Been having really constant sleep/crashing issues which can be as frequent as every few seconds, or spread out over the course of many minutes. I'm getting the below messages in my Console logs which i am assuming to indicate faulty hardware/logic board. but before i give up the ghost on this powerbook thought i would post here to see if there are any other solutions/remedies to this problem. could it also be a RAM issue? or something else that is fixable for a reasonable amount of money? or should i consider this machine toast. is it even worth bringing it in for a diagnostic? or is that $75 to tell me my logic board needs replacing?

Hey,
so the unsoldering was easier than i expected. Chip came right out, and after brushing off the solder particles and taping over the exposed solder points, the powerbook started up and was running for a few hours with no problems.
Maybe I was pressing my luck, but wanted to see what happened if i powered down and tried a reboot, at which point i am now faced with a non-starting computer. i get the chime, but then it never progresses past the black screen. I can feel and hear the components engaging, and i can force the power down by depressing the power button for a few seconds.
One problem solved another to now solve? Startup chime and black screen seems much less drastic than failing overtemp sensor. Any ideas what that could be? I tried a PMU resent already and getting the same thing.

PowerBook keeps logging itself off

I have had my 12-inch PowerBook G4 for 9 months. I'm currently having problems in which the PowerBook quits all applications, restarting itself and asking me to login. Any data which hasn't been saved beforehand is lost. I've heard that this may be a means of virus protection on Macs, but this process is now happening about 6 times a day for me, which is very time consuming and irritating.
Does anyone have any idea as to what the problem is, and if so, how to resolve it?
4 months ago my computer crashed (and I lost everything) when I updated programs. Could the current problem be related to this? I can't afford to lose any work again.
Many thanks,

WElcome Harlan,
FIRST of all: do a backup of everything which you want to keep. don't do it now, do it YESTERDAY !!!
include you rdocuments, photos, music, and so on, but also your applications (if you don't have the original cds).
2) Indeed, if your PB crashed when you updated programs, it could be that you suffer from this still now, for it could be that some of your (system) software is damaged. If this is the case, do the following:
-- back up everything you need;
-- do an "ARchive and Install"
"ARchive and Install" keeps (in principle) everything on your computer as it is, but installs a new version of the system. here is a link for info about it:
http://docs.info.apple.com/article.html?artnum=107120
if this doesn't solve the problem, do an "Erase and Install".
watch out: "Erase and Install" reformats the disk, thus everything will be lost!! the system will be reinstalled on the virgin disk. Your PB should then run as new. if it doesn't, then there is a hardware problem.
By the way, i don't think that this is a virus protection. if at all, it looks like a virus.
and, bytheway # 2: it's a good habit to back up frequently your documents; once a week or so...
Hope this helps. post back, if you need more help.

G4 PowerPC Mini puts itself to sleep...

...when under heavy load.
It usually happens when I'm multi-tasking (Safari, Adobe Illustrator or Photoshop, iPhoto or iTunes simultaneously etc) and the fan is spinning fast. A rough temperature check shows 58 degrees.
The fan will spin up faster, then the Mini will go into sleep mode and the fan stops spinning. Hitting any key will wake the Mini back up, the fan spins up again and I can resume working... for a few minutes.
Is the mini overheating? The vents are clear of dust, and I have turned it on it's side as the base gets very hot.
I have reset the SMC by unplugging/plugging the power cable while switched off, run Onyx tools and have all Apple updates.
Help!

This sounds very much like the right symptoms for overheating, and can easily be tested as such by letting the system cool completely while off, and then running it until it shuts down. If that takes longer than it takes to shut down when started from warm, then the system is responding to CPU load and/or lack of ventilation.
I see you mention the vents are clear, but it's entirely possible there is debris built up inside the unit that is blocking the air flow, or that the CPU heatsink is loose, or the fan itself no operating effectively. It's also not uncommon to find in the G4 minis that the thermal pad between the logic board and the base is deteriorating, effectively reducing the ability of the system to loose heat that way, however, since you mention the base is hot, that seems less likely in this case.
By the way, the SMC reset which applies to Intel systems not G4 ones, does nothing when applied to a mini such as yours. The correct procedure to reset the power management unit in a G4 mini is:
-Unplug all cables from the computer, including the power cord.
-Wait 10 seconds.
-Plug in the power cord +while simultaneously pressing and holding the power button+ on the back of the computer.
-Let go of the power button.
-Press the power button once more to start up your Mac mini.

Wy does the default "omw" keyboard shortcut keep putting itself back on my iPhone??

That's one of the first things I did, delete that shortcut because it totally defeats the purpose, "omw" is 3 only characters long and everyone knows what it means. Especially when texting to a non iOS person, when the number of characters counts, so this is a ridiculous shortcut to have, in my opinion. I delete it, but then eventually it just comes back which is really annoying! How do I erase that shortcut and KEEP it gone??

Oops, I mean "why," not "wy." When I type too fast this iOS keyboard tends to omit letters.

My MacBook just put itself to sleep! HELP!

Is this normal??? I just had the hard drive replaced in March I think, so I'm hoping it isn't broken or anything. I was just sitting here on my bed with my laptop on a piece of wood so it won't overheat and out of nowheres my screen just went black and I looked down, and the little sleep light was blinking....
I don't think it's normal, so I thought I'd ask. Please help if you can!
Thank you in advance.

T61p putting itself in sleep mode while gaming

I got my T61p since January and I'm pretty tired of this issue. I've read on the net that it is an issue with some laptop that has a defective motherboard when using two stick of memory (which is my case). Is there any mean to get this fix?
Everytime I start to game for a little while, I have to use a lapcool or else it shut itself off. The heavier the game, the faster it happen. So please....

I've written my first post a day after I had that shut down I described. Since then, it's running real hot and I'm having trouble with my wireless connexion. I'm having trouble connecting to networks and my download speed is playing yo-yo. HWMonitorPro is currently showing 87 Celcius degree for the CPU (max 95) and my GPU is 71 Celcius degree while in Vista (I haven't gamed with my laptop since I turned it on). The TMH1 sensor is giving 86 Celcius degree right now and has hit 91. I'm pretty sure this is not normal. What should I do?
