My macbook goes into 'sleep' mode when my mobile runs over the bottom left corner, next to the trackpad, does anyone else have this problem?

Not sure if anyone else has this problem. I only noticed it a few weeks ago when I left my mobile on the keyboard, towards the left of the trackpad. When I started typing I accidentally nudged my phone off the board and then everything went black. I hit any button and everything turned back on again. I'll assume that it went into 'sleep' mode. Is this normal or should I be worried about the health of my mac?

I am facing pretty much the same problem ... although sometimes the click does work on other parts of the trackpad, but largely I have to stay focused on the left bottom corner. It's getting slightly frustrating esp. because I like the click better than the "tap" and my MAC is only a month old!!
Is this a software issue or a h/w problem?

MacBook - stop going to sleep mode When lid closed

Hi ,
I am using handbrake to convert video files on macbook .
I want to close the laptop lid and still want the process to run in background .
Some one mentioned that if the laptop lid is closed and the system is running it gets heated rapidly .
I want to do this for 45 minutes ( commute between office and home ).
So , how do I close the lid ( display ) and not allow the system to go to standby/sleep.
Thanks
macbook Mac OS X (10.4.9)

You could also use InsomniaX.
I do not think that it's that bad for your macbook (heat generation); see this article: How to use your PowerBook G4, MacBook Pro or MacBook with the display closed.
I would not recommend picking your notebook up, though, since the hard disk's heads could scratch your hard disk... That's one of the things standby prevents.
By the way; why wouldn't you use standby? Your mac goes in standby rapidly, and wakes up even faster!

Laptop not going on sleep mode and on shut down light remain on in Windows 10

I have updated Windows 10 in my laptop and after this update from 8.1, my laptop is not going on sleep mode when I put the laptop screen down. Moreover, when I Shut down the laptop, it is almost shut down everything closes except the lights. Light remain on for indefinite time. Then, I have to press the power button for sometime in order to forcely close all the lights. Please give me the solution.

All-in-one 6830 printer Does not enter sleep mode when connected to a phone line

HP staff help. HP all-in-one printer 6830 does not enter sleep mode when conntected to a phone line via 1-Line jack. The Firmware is PNP1CN1521AR. On August 1, 2015, I purchased an HP all-in-one 6830 printer and upgraded to firmware PNP1CN1521AR.When a phone line is connected to 1-Line jack of 6830, the printer will no longer enter sleep mode and the display remains on indefinitly.Removing the phone connection either from the wall outlet or from the printer causes the sleep mode to work correctly again where the control panel display turns off after 5 minutes (or optionally after 10 or 15 minutes).This problem was previously reported by a user and has not been resolved, see:http://h30434.www3.hp.com/t5/Other-Printing-Questions/Sleep-mode-of-Officejet-Pro-6830/td-p/4772182 The user did not receive a resolution to this problem according to the thread.
There seems to be a 6830 printer firmware or hardware problem causing this. HP should be able to confirm this problem on 6830 easily.
Please advise ASAP.
Thanks

It's a regular analog phone line. I've tested it with other phone lines. No difference. I have another all-in-one printer which works fine (goes to sleep mode) when plugged into the same phone line.
The 6830 works ok in other aspects. The only problem is the sleep mode. Any 6830 with the firmware I mentioned should replicate the same result, regardless of anything else. The previous firmware to PNP1CN1521AR also created this problem according to the original report of this problem by another user.
I'm sure there's a bug in the firmware. A subroutine in the firmware monitoring the incoming fax ringing, mistakenly, sees the voltage across the phone jack pins as an event and wakes up the printer instantly even though there's no ringing. As the previous user also suspected, there seems to be an error in the phone line voltage threshold used by the firmware. The present firmware always sees a ringing at the phone line which causes it to never stay in sleep mode.

Prevent Macbook/Cinema display sleep mode when switching from plugged-in/off

Hello, I've a macbook connected to a Cinema Display. On Energy Saver, all is set to never go to sleep. I'm trying to prevent my macbook going to sleep mode when I plugged off it. Do you have any solution for this?

KinoBillie wrote:
Hi tjk,
Yes I mean when I disconnect the power supply (that comes from the Cinema Display) the macbook pro goes into sleep mode until i press a button on the keyboard, then it returns into running mode (even if in energy saver all is set to never go to sleep).
I would like that, if there is a power cut in my house, the mbp does not go into sleep mode but continue to be in execution (by means of battery) avoiding sleep mode.
Thanks
Looks like someone already cut in to try answering, but I'll answer the question you asked me anyway. You can read Apple's directions http://support.apple.com/kb/HT3131 and see that unplugging is the cause. It's not really an issue, it's just the way it works.
Contrary to the statement "There's no way around it." you may want to look into UPS (uninterrupted power supply) if it's important enough to you. I have never used one so I am not familiar with them, but by their very nature/purpose, I would think they'd do what you need.

Early 2008 iMac (8,1) randomly goes into sleep mode

Hey,
My early 2008 iMac (8,1) on 10.8.2 goes into sleep mode by itself. I've played around in Energy Saver, tried resetting SMC, NVRAM, replaced HDD, reformatted HDD, installed smcFanControl, reinstalled Snow Leopard, Lion, Mountain Lion. None of that worked. Took it to the Genius bar, performed some diagnostics tests and they said everything worked properly. Does anybody have the same problem? I can still use the computer for general computer use (light web surfing and e-mailing), but it seems to go into sleep mode when I have a lot of applications open and especially when watching videos. I've tried researching this problem, but I've haven't found a definitive answer. Right now, the Genius that I've been talking to thinks it may be the RAM. I'm waiting on new shipments of test RAM to arrive at the Apple Store for him to properly diagnose.
Thanks,
Jason
iMac (8,1)
2.8 GHz Intel Core 2 Duo

ATI Radeon HD 2600 Pro 256 MB
1TB 7200 RPM SATA ST1000DM003-1CH162
If you want to read the whole time line, I've included it here. I apologize for it being so long.
At first I was running Lion (10.7.5) and the computer would enter sleep mode whenever I was doing anything with video. For example, watching YouTube videos and chatting on FaceTime. And funny enough, I distinctly remember watching a bunch of movies with VLC and the computer did not go to sleep (Although, this is not true anymore). I could wake the computer up and use it, however within a few minutes the computer would re-enter sleep mode. The computer seemed fine and I could access all of my files. Tried resetting SMC and it did not resolve the issue.
I made a Genius appointment to see if they were familiar with the issue. The iMac passed the in-store diagnostics test; it said all the components were functioning properly. He told me to bring it home to do a fresh re-install of my OS and then run my computer to see if the problem persisted. I took it home and reformatted my HDD with a 35-pass erase, re-installed Snow Leopard (10.6.8) and declined to transfer any backups from Time Machine. I was using a fresh system and sure enough, the problem persited. Tried doing the same thing again but with Lion (10.7.5) and still no luck. So I made another appointment and it passed the in-store diagnostics test again. I let them keep the computer for a 24-hour diagnostics test. They told me they would diagnose my computer with the OS on my HDD as well as a copy of OS that the Apple store deemed 'good' on an external HDD. The Genius called me and told me that my HDD failed their 24-hour diagnostics test and recommended I replace it. I initially had a 750 GB HDD, and the Apple Store could only offer me a 500 GB HDD ($200). I opted to take my computer to Carbon Computing, an authorized dealer in Toronto, to have a 1 TB Seagate HDD ($170) installed with no OS on it. I brought it home, performed another 35-pass erase and installed Snow Leopard. Problem still persisted. Repeated with Lion, still unsuccessful. Looking back, I was so excited that I just had to replace the HDD to fix the problem, I forgot to ask the guy if he could recreate the issue.
I began to suspect that it was a heating issue. So I installed Temperature Monitor and smcFanControl, and cleaned the fans as much as I could without taking the computer apart. Without smcFC on I tried to recreate the problem and I noticed that the Power Supply Position 1 reached 95 degrees Celsius, and Graphics Processor Temperature Diode reached 97 degrees Celsius before entering sleep mode. I don't know much about temperature sensors and what they monitor specifically, and so I couldn't draw any conclusions from that data. I turned on smcFC and cranked the optical drive speed to 2000 RPM, HDD to 3000, and CPU to 3000. The computer still went to sleep but the temperatures were below 90 degrees Celsius before entering sleep mode. I've tried researching here and on the internet about normal operating temperature ranges of iMacs and generally found that most do reached that temperature but they do not go to sleep mode.
Then I thought it may be a problem with Lion so I upgraded to Mountain Lion. The issue still persisted. Tried resetting SMC and NVRAM, did not resolve issue.
I called the same Apple Store explaining to them that their recommendation of replacing the HDD did not resolve the issue. They told me to bring it in and have them check it out again. I went through the same process I did before; the iMac passed all of their diagnostic tests. The Genius told me this time he will test out the RAM. He called me and told me that he could replicate the problem and so he proceeded to put in a stick of 'good' Apple RAM, but the computer would not work. He said the 'good' Apple RAM was damaged, either before or in the process of putting it in. He plugged in my old stick of RAM and the computer worked. He tried to recreate the problem and claimed that the computer ran for over 24 hours with an existing movie on my HDD playing and it did not go to sleep mode. However, once I brought it home I played the same movie right away and it turned off 17 minutes into the movie. Tried resetting SMC and NVRAM again, ran the movie again, still went to sleep.
And that's the story for now...

Now to find out WHY it does it at home only. How hot is it at home? Have you checked the AC current/voltage at home?
Well they were able to replicate the issue at the Apple Store the second time I left my computer there. Anyway, we don't have any heating on at my house at the moment. It's usually from around 20-23 degrees Celsius (72-75 F). Temperature Monitor says ambient temperature is 30 degree C though...
I'm not really sure how to check the AC current/voltage at home, but my computer worked before I moved it. So I'm not sure if that is the issue.
I normally only have speakers set up to my computer and a wired keyboard. The speakers are powered separately. I would assume that at the Apple Store only the power cord and wired keyboard are connected.
What is the Power Supply Position? And what does it do?
Thanks for your help!

Updated to windows 10 and now my computer stays black when it goes into sleep mode

I just updated my computer to windows 10. Whenever it goes into sleep mode and i try to move the mouse it just stays black and i have to turn my computer off and then on again. after that it finally works but its just annoying. I already tried updating my card driver, but it said it was already up to date.

My iMac i7 quad was having the same symptoms with the blue screen and long startup times a couple of months ago. Apple Care told me to bring it in to the local Apple Store, and after some diagnostics, the hard drive required replacing. It took one day to replace the hard drive and my iMac is running great. I only had the iMac for about 12 months when the drive needed to be replaced. Not sure if that is your Mac's problem, but it was for mine.

My macbook pro 2.0 early 2011 will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

Alo, my Macbook pro i7 2 GHz Intel Core i7 (early 2011) will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

There is no output from that command line? Maybe the pid changed.
I'll repeat what I am trying to find out...
1. You do a pmset -g on the terminal.
2. The output from that pmset should have a line that says "sleep 0 (imposed by n)" where n is some number.
3. The ps ax | grep n is supposed to display what the process associated with n is.
It's the output from step 3 that should indicate what is causing you not to sleep.
But speaking of sleep, that's where I am going.

Mac Pro randomly goes into sleep mode

My (mid 2010) Mac Pro, OS X.6.8, randomly goes into sleep mode and I can't wake it, have to power it off and reboot. Just started to the best of my knowledge Friday (Jan 6, 2012) I've had it happen surfing the web in Safari, while working on an illustration in Adobe Illustrator, while running Apple Hardware Test, using 23" LCD connected by HDMI and DVI-D, Disconnected monitor and connected 12" Cintiq (LCD Tablet).
The monitor goes black, says "there's no signal coming from your computer", none of the keys will wake it. I have to hold down the power button until it turns off then power it back up. The time between the sleeps varies, 38min, 1hr 34min, 5min, 2hr 17min, 12min, etc. I disconnected everything (except keyboard, mouse, monitor) still the same. Opened and removed the ATI Radeon HD 5870, and noticed the PRAM battery, replaced it with a new one, thought that fixed it, worked for a long time then it happened again.
Tried Apple Hardware Tester again, it said everything is fine, ran it again an error popped up: 4SNS/1/40000000:Te1S-99.364, wrote it down then it slept.

The next time this happens open your mac and see if there is still a fan running. If so you are not sleeping, you are in a thermal cutoff. Keep you mac cover off.
Now reboot as you always do. Take a look at the fan in your 5870. Is it spinning? If so, try to keep an eye on it and see if you can "catch" it not spinning.
When the fan doesn't start, or if it does then stops, the card will overheat and the machine will go into thermal cutoff. The amount of time is variable.
I speak from experience. I am currently on my third 5870 video card. Both the previous two had this fan problem. The only wrinkle in my theory for you is that I wouldn't expect more that, say, 15 minutes of up time at the most, not hours like you got. But it may be that your card is starting ok, but stops sometime later. I chalk it up to the lousy fans Nvidia uses in the 5x70 cards.
FWIW, if you happen to catch the fan stopped before the machine goes into thermal cutoff you can give it a little nudge with your finger to get it going again.
I recommend one of the various temperature monitors. I use iStat Menus and display some key temps in my menu bar. Of course after going through two of these cards I am a bit paranoid!
Some other temperature monitors:
iStat Pro
Temperature Monitor
Hardware Monitor
Note, after typing all this I also realized you got a AHT 4SNS error. I would run AHT again to see if you get that error again. If so that means "Check Main Logic Board" and you may have a more serious hardware problem than just a video card! So my other recommendation is that when you machine fails again look inside for any lit diagnostic leds. There's some near the dimms but there are others on the board as well.

Week old IMac G5, Version 10.5.2, goes into "sleep" mode randomly....

My sister has a brand new IMac G5, OS X version 10.5.2, the screen randomly will go black, it still stays on, it's like it goes into sleep mode, but force quit wont work, nothing works, restart is required in order to get out of it.
On another note, when she restarts the computer, and sometimes when she's just starting it up not on a restart, the computer will have colored lines running down the whole screen, when it gets to the blue loading screen, it freezes there, where once again it requires a restart. Problem is, the computer is less than TWO WEEKS OLD. I've had my mac for years and cant figure out the problem, anyone that knows of, or has had similar problems and had them fixed that could help out would be nice. Thanks!

In fact, what your sister has is an intel iMac, not a G5, those were discontinued a couple of years ago. She has telephone support for 90 days and should call Apple immediately for a solution to her problem.

Mac goes into sleep mode amd doesnt come out!!!!!!!

Hi, new to this so sorry if this is a dum question. I have installed Snow Leopard on my IMac and Air. No prob on the Air but probs with the IMac. Everytime it goes into sleep mode I get a black blank screen and it wont come back up? have to reboot everytime or leave front row on with a slide show! any ideas welcome?

I looked around the internet and found an old post that seems to have solved the problem. I had a relatively new USB port (powered) that I unplugged and, ta da, the problem disappeared. I'm not sure why this happens (I'm not a tech person) but it seems like this should have been worked out in testing somewhere.

Mac Tower Pro 10.8.5 keeps going into sleep mode

Purchased from Apple, refurbished 2012 Mac Tower Pro. At the same time, purchased a new Dell U2713HM, 27" monitor.
Have been operating on this new system since about the first week of December 2013.
Issue:
The computer has constantly gone into sleep mode after a few minutes of no activity. I can have iTunes radio playing, but the system still goes into sleep mode. As I am typing and moving the curser, the machine stays awake.
This has caused much frustration because when it goes into auto sleep mode, it quits all programs that I am in, and when it does this, I lose all the work I had accomplished. It litterally closes everything and goes to sleep in about 2-3 minutes of no activity.
BTW: the computer and monitor have all its new OEM cables that came in the box, when I purchased the units.
Solutions attempted:
System Preferences — Energy Saver: computer sleep and display sleep set to "never" and unclicked the box "Put hard disks to sleep when possible."
Dell settings: Turned off all energy savers.
Results:
Nothing. Problem persists.

I apologize for the angst. The problem has cost too much money in lost time and material because when it would automatically shut down after a few minutes, all my work was lost.
I misunderstood the terms of the warranty. Thank you for your input and patience. Much appreciated. For the benefit of others that experience this with a new Mac that auto shuts down. Check the following:
1. Go to System Preferences.
2. Click on Security and Privacy.
3. Click on Advanced (bottom right corner)
4. If the first line is checked (Log out after 5 minutes of inactivity); uncheck it and then click OK button.
5. Be sure to click the lock before existing Security and Privacy.
Now the machine will cease shutting down programs to go into sleep mode as soon as machine is inactive for a few minutes.

My macbook is two and half year old, going to sleep mode randomly

Having used this Macbook for almost two and half years, my machine has suddenly generated the problem of going to random sleep. It started as an infrequent thing, then it started happening on a regular basis, to the point that it became almost impossible to work with it. When the computer goes to sleep mode, it doesn't wake up with any key, it has to be woken up by pressing the power button lightly.
Here are the steps I took:
1. The normal thing I did was search Apple Forum and then reset SMC, PRam, then changed energy saving options, everything. Nothing worked.
2. Ran the hardware test and no problems found.
3. Ran the Macbook with all options: with just the battery, without the Magsafe connected, with Battery and Magsafe connected together, with battery removed and the computer running on Magsafe only. Random Sleep continues
4. Thought must be a connection issue and ran to Apple Store in Kolkata, India, thinking that it could be a connection issue with the sleep-mode cable. Apple Store kept the Macbook for seven days, saying that they needed to check the machine, returned it on the seventh day saying that the machine was fine and charged me Indian Rupee 1,500/- (about $ 34). I came back home and the problem persists.
(Here I would like to add that Apple Service in Kolkata *****, probably ***** all over India, simply because Apple is not a major player in this country. The service engineer at Apple Store was at a loss with my problem and after seven days could only say, "We have done our internal tests and found no problem with your Macbook." When I asked about the Sleep Mode sensor connection, he said, "That is working fine, we have checked that.")
5. After coming back home, I faced the same problem, this time with lesser time gap. It would go off to sleep every one minute or so. I decided to set my computer on "never to sleep mode" in the enery saving option. Alas, that didn't help either.
6. I redid the hardware check, only to find that my computer hasn't detected any hardware problem.
7. Now, as a previous Windows user, I thought that the problem must have been with the OS. So, at the risk of losing all my files, I decided to reload the OS. (My original OS DVD was Leopard, but it was later upgraded to Snow Leopard by the vendor free of cost). I took backup in Time Machine, and backed up the documents in another Disk and reloaded the OS. All seemed fine so far, for about 10 minutes. I was now confident that finally I could solve the problem and was then planning to migrate my previous files to my newly loaded OS-X. Alas, I was wrong. Before I could connect the external HDD to my computer, my Macbook went back to its previous trick of falling asleep.
I'll definitely take back my Macbook to Apple Care tomorrow, but with my experience here in Kolkata, don't know whether they would be able to solve anything. Last time I had to show them the posts in Apple Forum to prove that Random Sleep is a problem that happens to Macbook.
PS: My Macbook is with aluminium body bought in January 2009. Out of warranty. My optical drive conked off long ago (after about 15 months or so after I bought the Macbook) and I live with an external drive.

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 the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
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. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. 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.
