Macbook pro not starting after sleep

Dear Community,
I have a macbook pro purchased about 3 years ago. Since last couple of months, it wouldn't want to wake up after putting to sleep. I had to turn it off and then back on. One fine day, it just wouldn't wake up. I went through all the resets with different key combinations but to no avail . Finally i went to an apple store (not from the shop i got it); i was bluntly declined saying they accept laptops for repair/check only if the product had been purchased at their shop. I tried other and samething. I didn't expect this treatment. Finally found an Apple certified service center. They even charged me to check it (don't know if that's normal. If it is, apologize for my naivity) and finally told me the problem - the logic board needs to be replaced! The cost of which is as you can imagine, is extremely high (around 550 euros + extra for work + tax - it is high for me ).
I changed from pc to mac hoping better services/products. But I must say I am really disappointed by this . Spending a lot to get a product like this and then such dissapointment.
Sorry Apple, but that's not what I was expecting .
A sad ex-mac user.
P.S: I didn't know where else I could share my frustration.

Why will macbook pro not go to sleep with Lion OS?

Why will macbook pro not go to sleep with Lion OS?

Test after each of the following steps that you haven’t already tried:
Step 1
 ▹ System Preferences ▹ Energy Saver ▹ Power Adapter ▹ Wake for network access: uncheck. You may need to unlock the preference pane by clicking the lock icon in the lower left corner and entering your administrator password.
Step 2
 ▹ System Preferences ▹ Energy Saver ▹ Schedule… ▹ Start up or wake: uncheck
Step 3
 ▹ System Preferences ▹ Print & Scan ▹ Open Print Queue...
Check all printers for unfinished jobs. Deal with any you find.
Step 4
Disconnect all wired peripherals except keyboard, mouse or trackball, and monitor, if applicable.
Step 5
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select All Processes from the menu in the toolbar, if not already selected. Enter “powerd” (without the quotes) in the "Filter" text field. Select the powerd process and click the Quit Process button in the toobar (stop-sign icon.) In the sheet that opens, click Force Quit. You’ll be prompted for your administrator password. The process will be relaunched immediately.
Step 6
Boot in safe mode and log in. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
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.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the Mac OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
If sleep now works as expected, go on to the next step.
Step 7
Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
Step 8
If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
If you still have the sleep issue after booting out of safe mode, post again.

Macbook Pro needs restart after sleep...

My Macbook Pro has starting doing this thing where the screen will go darker and it will tell me I need to restart by holding the power button. It happens pretty often when the computer wakes up from being in sleep mode. What's the deal?

Here's a console log detailing a wake sequence with failed Bluetooth and USB.

Macbook doesn't start after sleep

When my macbook pro goes asleep, after appr 30 minutes it doesn't start up anymore. I have to start up by holding the on/off button for 10 secs . After that my macbook acts very slow. When I close the macbook and start up again, it works oke. Until it falls in sleep.......it starts all over again.
What to do?

Hi Hoekiebest,
If you are having unusual issues waking from sleep on your Mac, you may find the troubleshooting steps outlined in the following article helpful (in particular, resetting SMC/PRAM):

Macbook Pro not starting up after 10.9.3 install

Hi everyone. I have a mid-2010 15 inch Macbook Pro. After putting it off for some time, I went to install the 10.9.3 update. However, after installing the update, the computer won't start!
A progress bar appears under the Mac Logo during start-up, but it only gets about 1/5th of the way through, when the bar disappears and then the mac shuts down. I've attempted this at least 5 times and it always does the same thing.
I held option during start-up to boot into the Recovery disk, and tried to repair the partition (I also have a bootcamp partition), but it said it was unable to repair. What's my next step? I have a time camp back-up from 50 days ago, so I could restore from that but it wouldn't be ideal. Is there a way to backup my files in it's current state in anyway?
Any and all help is appreciated. Thanks!

Hey NickinTampa,
Thanks for using Apple Support Communities.
Looks like the computer won't start and you have tried repairing the disk. This article gives several other ways to try and resolve startup disk issues.

MacBook Pro not waking form sleep (sometimes)

My Macbook Pro is not waking from sleep (sometimes). To be very specific; the only time this happens is when it goes to sleep automatically, with the lid open, while plugged into the magsafe power cord. When I hit the space bar to wake it, the keyboard lights come on but the screen remains black. I do not have any problems with waking from sleep if I close the lid to force sleep (while plugged in). I also do not have any problems at all, if the computer goes to sleep while running on battery power. (I have had this MBP for about 18 months, the first year I had no issues at all. The problem started shortly after Lion was installed. (I also have a iMac with all the same software, almost identical set up, purchased at the same time as my MBP but have never had any sleep problems with the iMac, none even since Lion install.)
We do not have an Apple Store near us, but I have had the MBP in for service 3 seperate time to our local authorized Apple service/dealer. It is tricky to diagnose, because the problem does not happen every time. On average it won't wake from sleep 1 out of 3 times. Each time the service techs were able to re-create the problem but could not come up with a cause or solution, their only advice was to re-install Lion.
I have tried 2 different re-installs of Lion. (Both times erasing the hard drive first) The first time I did a clean re-install of Lion, then restored all of my data from Time Capsule. That did not work, the problem presisted. So I tried a second clean re-install of Lion and this time I did not restore from Time Capusle, I only re-installed critical docs from a flash drive and re-installed all other software (such as MS Office, Photoshop, etc.) from their original discs. I though this had fixed the problem but within a few days the problem re-occoured.
Any ideas would be appriciated, I have tried almost everything, I have days and days worth of time invested in trying to fix this issue. Thank you!

I had this problem with my MacBook Pro for a long time, and fixed it by changing the sleep mode. Here's how:
Open Terminal
Type the following:
     pmset -g | grep hibernatemode
It should say something like:
     hibernatemode 3
Here's an explanation of the different types of hibernate modes:
0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
5 - This is the same as mode 1, but it’s for those using secure virtual memory (in System Preferences -> Security).
7 - This is the same as mode 3, but it’s for those using secure virtual memory.
To change your sleep mode, use the following command:
     sudo pmset -a hibernatemode 0
(replace 0 with whatever hibernate mode you desire)
For my MacBook Pro, I changed it to 0, and it works great. It's super fast to wake and sleep, which is a plus. The only downside of hibernatemode 0 is that if your battery runs out your computer doesn't hibernate - it shuts off. This doesn't matter, though, because with Lion everything is autosaved, so really hibernate 0 is all plusses.

Macbook pro not starting up. fans spin only for a second.

Hello.
Okay so my MacBook Pro won't start up. When I press the power button I hear a weird sound like something trying to move but not being able to and after a second when its shutting down I hear it again. I've taken hdd and dvd rom out and the weird sound still comes. I removed both ram modules and the computer starts beebing the error sound. I tried srarting with only 1 ram module and nothing. The fans spin for a brief second and then stops. If I hold down the power button it stays on until the sleep light start to blink and then shuts down again while making the weird sound. I tried removing the battery also.
Any ideas?

Nice botch job there Dr. Zoidberg.
If you would have taken it into Apple for a free evaluation, it might have been a simple fix.
Since you have basically ruined your machine, costing more to repair than it's present value, you should just connect the internal drive to a new Mac using a SATA to USB adpater cable and use Migration/Setup Assistant or manually transfer files and trash the old one.
You also could get a Windows PC tower, where you have the option to do your own surgery as it's modular designed for that purpose.
Just install MacDrive into Windows and ues the SATA to USB adpater to access your files on the Mac formatted drive.
Good Luck

MacBook Pro not charging after Mavericks update

Is anyone experiencing an issue with not being able to charge their Macbook after updating Mavericks? I'm unable to charge my 2011 MacBook Pro that has Mavericks installed. This issue appeared only after running the latest update from Apple for Mavericks. I tried running the SMC reset but it still won't charge.

I had the same issue, when i updated to mavericks my charger stop charging sometimes the light would go orange sometimes green most of the time would be off but charging, i returned to mountain lion as the moment of the reinstallation was complete the charger started working and light was on and now is working perfectly no problem. I guess i will stick with mountain lion for now. I hope this helps.

Macbook pro not booting after software update

Dear all,
Since two days ago my macbook pro hangs at the gray apple screen, the round circle keeps on turning. Kept it running for nights but it does not exit this status. I read on the internet that I could run it in verbose mode, that's what I did, see screenshot below. What do you recommend? This seems to be a hard disk issue. How can I boot up in safe mode and possibly recover the hard disk data? Any other recommendations?
Thanks,

Get your Mac to a Computer repair service, or do it yourself. You will need to put it in an external SATA reader, like I did. I recovered files via an older mac running Slow Leopard and copied files to it.
What I did:
1. You will have to remove the screws at the bottom of your Mac, in order to get to the HDD (or SSD, whatever you have).
2. You need to remove the HDD and put it in an external Case/SATA reader
3. Copy files from your HDD to another Mac
4. On that other Mac, go to Disk Utility (search in spotlight) and Erase as 'Mac OS X Extended (Journaled)'
5. Download Mountain lion on another Mac from the AppStore, and go to that Applications folder.
6. Right click on the downloaded file and select “Show Package Contents”. Go to “Contents” and jump inside the “SharedSupport” folder and you’ll find a file titled “InstallESD.dmg”. Copy this over to the desktop.
7. Plug in a USB flash drive to your Mac having at least 4GB memory. We highly suggest going ahead with an 8GB one just to be on the safe side.
8. Now open up “Disk Utility” and drag InstallESD.dmg from the desktop to the left-hand sidebar. Select the attached USB from left side and click on “Partition” tab.
9. Select “1 Partition” from the Volume Scheme dropdown menu. Choose “Mac OS Extended (Journaled)” from the left.
10. Now click on “Option” at the bottom. Select “GUID Partition Table” and press OK. Now click on Apply at the bottom right to start formatting.. (NOTE: This is will erase all data on your USB flash drive)
11. Once the drive has been formatted, click on “Restore” (it’s right next to where you clicked on “Partition in Step 5).
12. Choose USB drive you plugged-in in Step 5 as “Destination” with the InstallESD.dmg file as “Source”.
13. Click Restore and type in your password (if you have any). This will create the intended Lion bootable USB flash drive
14. Reboot your Mac with the USB drive plugged in. Hold the “Option” key on your keyboard when you hear the iconic OS X startup chime. You can now boot into your Flash drive from there.
15. Follow the on-screen instructions to install OS X , and after that, reboot
16. Format USB back to FAT in Disk Utility, copy your files from old PC to new using the USB.
That's it, you're done . Takes a lot of time, but recovered my Mac this way!

MacBook Pro not starting up......

Hi,
My husband has recently bought a new MacBook Pro which was working fine until one day he went to turn it on and it does nothing but some up with a blue screen, the apple sign and then after a while a small circle with a line through it comes up (similar to a stop sign) and it does nothing else.
Does anyone know what could be wrong with it? He hadn't done any installing or updates and said it was absolutely fine before it stopped working.
Any help would be greatly appreciated, and where possible, a clean install avoided!!!
Many Thanks
Sleepy

it basically sounds like its just not recognizing the HD as the start up disk. can be a simple as some how the setting for it got messed up or as worse as the HD is corrupt.
along with the other suggestions (if those dont work or you have issues) try to boot with another machine using that HD as its start drive (use target disk mode on that, start it while holding T) and if that doesnt work you can probably expect the HD has some issue but you can still possibly access the info on it while using it it target disk mode to at least copy off the info to save it. i am actually waiting for a friend to get me an external drive so i can do that for her, her machine isnt not booting but might as well not be and you cant boot of her drive but i can at least access it

Macbook Pro not starting up no startup chime

Friday afternoon, I attempted to start up the Macbook Pro but after the Superdrive made a sound, I don't hear any startup chime. Yesterday night, after having to remove the battery and by inserting the RJ-45 Jack into the Macbook Pro, I finally got the thing to boot and I was able to back up both my Mac *AND* my iPhone 5. However, this morning, in spite of me taking the battery out and also going back to Wi-Fi connection, this morning when I had the Macbook Pro sleep (Macbook Pro Early 2008, 2.6MHz, 15-Inch), when I tried to wake it up, the Macbook Pro won't display any video, so I turned the Macbook Pro off by holding the Power Button until the Macbook Pro turned off. Now I tried to reboot the Mac by doing a PRAM plus an SMC Reset before I attempted to get the Mac to boot up again. I turned the power on, same thing happened on Friday Afternoon. That's the bad news. The good news is that I was able to have my Macbook Pro backed up whilst it was running yesterday night. The MagSafe Adapter is displaying a "connected" light (Green/Amber), and I know that the Superdrive is working fine, but I don't hear a start-up chime.
Now to tell you guys, I've been using a heavy amount of Flash on the Mac, and all I know is that Apple has been very ballistic against Flash due to Flash causing Macs to crash day after day.
Long story short. Turned the power on (even without the battery in), MagSafe Adapter is working fine, no startup chime. I also heard about the mass GeForce recall that affects certain Macbook Pros as well. I don't want to think it's the Logic Board or the Processor, even worse, the CMOS Battery. I also don't want to think that my Macbook Pro is infected with a Boot Sector Virus neither.
Seriously I don't want to see myself buying a new Macbook after 4 years of having the same Mac I have, but it could be the worst case scenario. I have my Mac backed up on the Time Capsule, just in case I must move to a newer, lighter Mac since I'm more of a mobile Mac user.

Well 4-5 years seems to be the average life span of a MacBook Pro computer depending upon use, how much dust it's inhales and hasn't been cleaned out
Also in my opinion that machine is too old to handle 10.7 or 10.8, despite Apple's say otherwise, you should have stayed with 10.6.8
All I can suggest is you run through this list of fixes, install OS X on a external drive (reboot twice from it to change the EFI firmware) and see if it's a internal hard drive issue, if you have to replace the internal drive, make sure to remove the fans and clean the vents there of dust, but it could be the heat damage to the video chip has already occurred and is irreversible.

MacBook Pro Not starting up, 8 min start up disk0s2 not mounted?

Hello,
I am having trouble with my 2011 MacBook Pro, runs on OS X Mountain Lion... So I left my computer on all night and it ran out of battery so this morning I charged it for a while and attempted to turn it back on..
So when I hit the power button, it went to a straight white screen, and after about 10 minutes, it took me to a start up help page with the following options:
Time up Machine Back up
Re-install Mountain Lion OS X
Get help online Apple Support
Disk Utility
I first just tried re-installing Mountain Lion, and I did, but nothing happened it still wouldnt boot up, so I did disk utility and attempted to repair my disk "Macintosh HD" and after it said it could not be repaired, to reformat it, and erase it. and then it changed to "Disk0s2" and it says its not mounted so now I don't know what to do, I tried re-installing Mountain Lion after and now it only gives me the "Recovery HD" option to install it on which isn't even possible cause it's locked...
Can someone help me??

Can you do this?

Late 2008 Macbook Pro not waking from sleep

I just go a new MacBook Pro, and occasionally (maybe once a day) after I shut the computer to put it in sleep mode, and walk around with it, It refuses to wake when I open the lid. I have disabled the "put hard disk to sleep" and using the smartsleep preference pain, have put the computer in "sleep only," but the problem still occurs. Whenever this happens, I have to restart my computer with the restart button.

Alex, do you have your preferences set to require a password after sleep or screensaver? Sometimes I have had issues with this dialog window not popping up. Also does the status light on the MBP glow constantly or fade in and out when you lift the lid up? If it is lit constantly and nothing is displayed that means the computer is on...what I do is just close the lid again and then wait for the light to fade in/out and re open, then it usually works.

Macbook pro not starting (Hard disk damaged)

Hello,
My macbook pro is not starting. I believe it is a mid 2012 model, 13 inch, 750 gb disk space, not sure if i5 or i7, OS Mavericks 10.9.3 or 10.9.4 not sure. I tried running disk utility and it said my disk was damaged; tried repairing but I get a message that disk utility cant repair the disk. I read about safe mode startup so I did that, but it does not work. The progress bar goes up to around 5% and the computer shuts down. Even if I don't press shift key the same thing happens; progress bar goes to 5% and computer shuts down.
I have a time machine backup on an external hard drive so I can use that to restore the system but that backup was done 2 weeks ago, I've some new files in the computer so I'd rather not do that. I want to be able to start my computer and copy files and folders onto external disk then perhaps reinstall the OS again. I also read about Fsck but I don't really understand that.
I don't know about computers well, please help me..

OS X- Gray progress bar appears under Apple logo during startup
OS X v10.6- Gray progress bar appears under Apple logo during startup
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
     Note: You will need an active Internet connection. I suggest using Ethernet
                 if possible because it is three times faster than wireless.
If the above does not bring about a resolution, then you need to erase the drive and reinstall OS X:
Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Why does my macbook pro not start up?

Today I changed ram on my old macbook pro. 667hz DDR2 type from 2X1 TO 2X2.
After i finished the installation my laptop has not worked properly. It currently runs 10.7.
No startup sound, and the white light at the bottom flashes constantly in sequenses of three. Three quick flashes.
What is wrong? Even when I re-inserted my old RAM the same problem occurred.
Please help!

MacBook Pro 3,1 15' 2,2 Core 2 Duo Late 2007.
I used the same buss speed (667 mhz) and the same type DDR2. Same number of pins.
I also checked what happened with 0 ram in slots, and then it started blinking constantly.
So it must see the RAM but the RAM seems useless for some reason...
