After shutting down MacBook Pro, it will only turn on after changing power outlets

The last few times i have manually shut down my macbook, and attempted to turn it back on several hours later, it wont turn on again. The battery level is fine, I've tried with and without battery connection, and I have reset the PRAM and SMC on the keyboard, but it still wont turn on.
SOLUTION:
The only way it WILL turn on is if I change the charger and move it onto to another powerboard.
It can't be the power outlet as both say that the computer is charging.
It also can't be the power outlet as this has happened at home as well as at uni.
Any ideas why it might be doing this and what I can do about it (other than never turning it off) would be helpful.
The rest of the computer runs fine.

I tried those already, did not work.
I did how ever remove the command key and wiped it down and it turns on perfectly!
but now the keyboard keys seem to be out of place or something. For example it makes a "ping" sound when i hit some of them, when i hit function or control it puts the letter Z.
Any input would be great!

Lighting bolt port shuts down macbook pro

lighting bolt port shuts down macbook pro once the cable is pugged in. What is the cause of this problem

Hi reginaldt,
If your Mac unexpectedly turns off when you plug in a cable (unclear if you are describing a USB Lightning cable or a Thunderbolt cable) and you have checked to make sure there is no debris in either the cable jack or port, you may want to try resetting the PRAM and SMC:

MacBook Pro will not charge when Computer is on. Can only charge when shut down, MacBook Pro will not charge when Computer is on. Can only charge when shut down

Hi can anyone help me? My MacBook Pro cannot charge at all (keeps showing not charging or not connected) when i am using it. only when i shut it down or let it sleep then wil it begin to charge normally. Does anyone know what to do??

You could always try a SMC reset -> http://support.apple.com/kb/HT3964 - but I don't believe that will solve your problem.
If I were you, I would take the machine to your local Apple Store or an AASP and have them diagnose the problem. It could be something very simple or it may be something more complex within the power management system.
Good luck,

Hp v195b flash drive shuts down MacBook Pro when inserted

Hi I hope someone can help me solve this problem.
I bought two hp USB flash drive v195b today and inserted one of them into my Macbook Pro 5,3 with Mac OS X 10.6.8
When I inserted the flash drive a screen turned up in my computer and asked me to shut down my computer on the switch on/off button. This was the only thing the computer reacted to. Nothing else worked.
I then inserted the flash drive in an older macbook with Mac OS X 10.4.11. In this one I could see it and I tried to make a partition using the disc utility tool, but the flash drive still makes my MacBook Pro shut down?
Anyone tried this or have a suggestion to how I solve this?
Thank you, Sanne

Facetime shuts down MacBook Pro

Did anybody else experience this with Facetime 0.9? It runs for a couple of minutes, then the computer shuts down unexpectedly. I've tried running it on a near fresh install of SnowLeopard on an external drive, but same thing happens.

Hi,
I have the MacBook Pro 1,1 with the 2Ghz Core Duo chip.
Mine was a Built to Order with the Hard Drive change to the larger one (that they had at the time) and the Extra RAM that could be pre-installed (Max 2Gb)
The Drive has a small (20Gb) space given over to Boot Camp and Windows.
I have CS 3, Photoshop Elements 6, TacoHTML, Skitch that I use regularly on there as well as CIV4 (which Distracts me from doing anything that serious on it at the moment). I also have iWork 08 Installed, iMovieHD, iLife and few other things
As EZ Jim has said I can run Facetime and iChat at the same time (in fact see Previews and Complete Video calls on both).
I could call out to EZ Jim's Mac and his Touch without issue from my end.
Accepting calls from EZ Jim's Touch were the problematic connections we tried.
I run Little Snitch which is an Utility which will tell you/Ask for Confirmation for each connection any Incoming or outgoing internet connection an App will make.
I tired turning Off Little Snitch at my end as the Connection was closing the App at the exact point I hit the Allow Button in Little Snitch.
I have 5 Crash Logs. (Home Folder/Library/Logs/Diagnostic Reports)
It is always the Last thread number wise that has Crashed although the actual number does vary.
None seem to implicate Little Snitch from what I can see.
In fact the things listed in the so called Crashed Thread point to things I know work (as in they are the same in successful chats and iChat Video Chats - mostly the Core and viceroy.framework)
My understanding is that as well as 10.6.4 you have to have the relevant Security Update as well
There is a Link to both 2010-006 and 2010-005 in the lower box on the left here http://www.apple.com/support/snowleopard/

Macbook Pro Shuts Down / MacBook Pro Doesn't Start Properly

I just had this problem today. When I tried to wake the macbook pro back from sleep, it didn't wake up, after closing and reopening the screen several times. Thus, I forced quit it by holding the switch button. Now, when I tried to start the macbook pro, the computer automatically shuts down in less than 3 seconds. I have tried resetting the PRAM and all that stuff but they don't seem to work. Has anyone had this issue before?

I am having this exact problem. In my case, I shut down my MBP before going to work. Once I reached work, I tried restarting and it shuts down almost immediately. I've already tried most solutions, but as I am at work, I have not been able to try the cd solution. Any help would be welcome as I do not want to have to reinstall the OS.

Draining battery to 0% shuts down MacBook Pro-10.5.6

On previous laptops and this laptop prior to 10.5.6, when calibrating the battery by letting it drain to 0%, I could immediately reconnect the laptop to the power adapter and then wake it, leaving all of my programs as they were. I was doing this before 10.5.6 and it worked the same way. I just recently, since upgrading to 10.5.6, tried this and the laptop shuts down completely, no sleep. I then have to do a complete power up.
I hope this bug can be fixed as I don't know how I'll ever be able to properly drain the battery to 0% without having to shut down everything on the laptop just as it gets toward zero.
I just confirmed that my 17" MacBook Pro (~1.5 years old) works - it is on 10.5.6, too, so there must be something specific about 10.5.6 and the new late-2008 MacBook Pro's and batteries that's causing the complete shut down.
Has anyone else experienced this or do you have any suggestions on how to improve the situation?
Thanks,

Hello there,
I was experiencing these issues and I do believe I have a solution to this. First, let me explain the process so that everyone understands what's supposed to happen:
When your battery gets too low, the computer is supposed to induce something called "Safe Sleep". Its a lot like Windows Hibernation. On safe-sleep boot, your computer attempts to detect its previous state. When the system detects a hibernated sleep, it attempts to recover that data. If it can't, it leaves safe sleep mode and restarts as normal.
So, it doesn't necessarily have to be your battery that is the culprit, it probably actually is your safe sleep hibernation file that can't be written to for whatever reason.
Here is what you do to fix the problem:
First, navigate and open this file in finder:
/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
When you open this file, Property List Editor should open and you should see the following Hierarchy:
1. Root:
1.1 Active Power Profiles
1.2 Custom Profile
Click the arrow (>) next to Custom Profile.
Now you should see AC Power and Battery Power. You can open either one of those.
You should see an item under those trees called Hibernate File. Take note of this files location. On most computers, it should be located at /var/vm/sleepimage
Quit Property Editor and then switch to finder.
Click Go and then Go To Folder:
In that box, type the directory name: (eg.) /var/vm
Click Ok.
Now you should see a couple of files. You should see the file sleepimage.
Select that file, then click the File Menu and then Get Info.
System should have read and write access.
If all is well there, delete that file. Finder will ask you for an Administrators password.
Once deleted, shutdown your computer.
Then on restart, you will need to perform a PRAM Reset. You can find information on zapping your PRAM here:
http://support.apple.com/kb/HT1379
Once you do that, allow your battery to run down again and it should hibernate properly.

Can't shut down MacBook pro

When I try to shut down my MacBook Pro it goes as far as the spinning wheel on the blue screen and will not complete the shutdown. I have to hold the power button to shut down completely.
Both disk and permission repair does not solve the problem.
Did a reinstall of Snow Leopard and still have the same problem.
Help please.

Check the directory*:

Make sure the hard disk isn't too full*:

Macbook Pro 15" will only boot up in Safe Mode - Please help!

My Macbook Pro will not boot up normally. It goes past the screen with the apple and the wheel and then just stays white. Also on the screen there are little rectangular blocks going across diagonally. In Safe Mode, it boots up but with little square blocks going across the screen. Can anyone help please?

Firstly, see this article: Mac OS X- What is Safe Boot, Safe Mode? and this one: Gray screen appears during startup.
Secondly, try the following:
Delete caches to resolve some startup problems:
Boot into single-user mode. After startup is completed you will be in command line mode and should see a prompt with a cursor positioned after it. At the prompt enter the following then press RETURN after each commandline:
/sbin/fsck -fy
If you receive a message that says "***** FILE SYSTEM WAS MODIFIED *****" then re-run the command until you receive a message that says "** The volume (name_of_volume) appears to be OK." If you re-run the command more than seven times and do not get the OK message, then the drive cannot be repaired this way.
If you were successful then enter:
/sbin/mount -uw /
rm -rf /System/Library/Caches/*
rm -rf /Library/Caches/*
reboot
I suggest you print out the above to be sure you do not make any errors when entering the commands. When in single-user mode you have 'root' access, so it's important that you not make any mistakes.
Lastly, reinstall Snow Leopard if the above doesn't help. This will not erase the drive.

When printing to my hp color printer from my MacBook Pro, it will only print in b

When trying to print to my HP color printer, my macbook will only print the document in black and white. I have looked at settings and I don't see an option to print to color.

Hmmm...well that narrows down things a little more. Has it ever worked correctly? Have you tried deleting the printer from System Preferences (under the Apple menu) > Printers & Scanners and then re-adding it again? Also, silly question, but have you checked the supply levels to make sure it has color ink in it?
Does the printer work correctly with another computer?
I know it is puzzling. I'm trying to think of all the ways to isolate this to one thing or another.

Shutting down macbook pro

The shutting down of my macbook at times is hanging or takes long ever since I upgraded the operating system to Lion. I am forced to hold down the on button for some seconds to shut it down manually. What could be the course of this?

Dear all,
at las I managed to get away with this problem. I found out that I had a problem with one of my RAM.
Now I am lookng at replacing it with a new one soon.
I am using only one 4GB at the moment and the problem is gone and all is workng well now.
Guy who are facing the same problem, better check that your RAM is okay. This could be one of the reasons to your problems.
Thank you all.

Gophoto.it Installer preventing from shut down macbook pro

Since two days, I cannot shut down my computer anymore. When I try to do it I get the message "The application Gophoto.it Installer has cancelled the shut down. To try again, quit Gophoto.it Installer and click on menu apple>Shut down
I cannot find any trace of this software on my computer (not on Safari/ add-ons nor Library).
Does anybody know what to do please?
Thank you.
Eric

Conflicting statements:
"The application Gophoto.it Installer has cancelled the shut down.
I cannot find any trace of this software on my computer (not on Safari/ add-ons nor Library).
I still see a Mac_Installer icon at the bottom of my screen next to other applications.
Can you please post a screen shot & also clarify your statement?
(I may have downloaded but not installed the program completely.
What makes you think you interrupted the installation? What were you doing at the time of the installation? If you click on the installer what happens? Is there an uninstaller? If so, use it to uninstall the app.

My macbook pro won't turn on. I press the power button and the little light on the bottom goes white only while I hold it down, the second i don't it goes off. When I do hold it down for a few seconds first it will be solid for like 3 seconds then start flickering

When i tried to turn on my mbp today it only turned on for like a second and then shuts off. The light on the front turns on and the battery is fully charged, but it just turns off in a second
http://discussions.apple.com/thread.jspa?messageID=10285598&#10285598
Hi, I have an Early 2008 Macbook Pro and I used it this morning but two hours later, I found it off. When I push the power button, the white light briefly comes on but it doesn't sound like it's starting up. When I hold the power button down, the white light comes on solid for about 5 seconds, then flashes rapidly. During this time I can hear the DVD drive and other components kick on, but once the rapid flashing stops, all power is lost again
The problem: Mac will not turn on.
1. If I hit the power button it is trying to start working (white light is blinking, HDD rotating, CD noise and so on), but gets shutdown as soon as I release my finger from the power button.
2. The maximum "Working" time is about 5 secs. During this time fans are working, white light is lighting, HDD working, CD does its usual noise. At the last two seconds white light starts flickering.
3. If I remove all memory slots it is working as usual!!!, I mean working without pressing a powerbutton constantly... and asking for a memory of course.
How it happened: well, it is usual thing then you are in hurry. Accidentally I hit restart. I didnt want mac to load again, so I did a force shutdown (5 secs an a power button). Thats it.
What I tried to do: I did all those "shaman" hotkeys to restart SMC. I spent a day!!! by driving around my city and asking Apple providers to fix it with no luck.
What I am planing to do:
1. I have an Apple service center here in the Tallinn who are ready to do some diagnostics. The only thing is - I dont trust them my HDD. So I am gonna clone my hard drive data somethere before they get my mac in their hands.
2. As soon as diagnistics is done I will get a price offer to fix it. It definitely wont be a cheap, since my mac is year and two months old (funny, two months and you are screwed).
3. If it will be too expencive I gonna do DIY repair.
What I would like to say to the Apple: please investigate that problem. The motherboard is definitely working. I can not fix it myself with no necessary equipments here, so I have to do expensive motherboard logic purchase.

Hi rightturn,
Thanks for replying.
I am still not sure about the success story. According to the http://www.xlr8yourmac.com/feedback/MacBookProvideofailure.html topic and comments you have to have "chime" sound and numlock (or capslock ???) button to work. Those two are the main criterias to pass the nvidia failure test.
Another thing is the USB which is should be powered on as well.
As you could see on the youtube video this macbook does not have chime, and keyboard seems does not work too.
So... will see what happens next after the weekends I am gonna call them for an updates.

Macbook Pro retina will not turn on

I bought a 2012 Macbook Pro Retina 13" off Craigslist today. It will not turn on. I tried resetting the SMC and disconnecting the battery and reconnecting it. It will still not turn on, the battery has been charging for 2 hours already and it's still amber on the magsafe. It still has warranty coverage until 2014 so my next stop is the apple store. I thought I could fix it myself but it is pretty tough to narrow down the cause.

I tried those already, did not work.
I did how ever remove the command key and wiped it down and it turns on perfectly!
but now the keyboard keys seem to be out of place or something. For example it makes a "ping" sound when i hit some of them, when i hit function or control it puts the letter Z.
Any input would be great!

IPod Touch 5th Gen shut down by itself, and will not turn back on?

I was just on the YouTube app when suddenly my iPod shut itself down, and the battery was well over 50%.
It will not turn back on, and when I plug it into the charger, nothing changes. Any suggestions?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
