My MBPr (mid 2012) displays a black screen on startup but when I close the lid and open after a few minutes, it seems to wake up as it should.
Can anyone advise what is going wrong on startup and what steps I can take to resolve this issue? This has been occurring for the last month or two.
The specs of this machine are:
Macbook Pro Retina (mid 2012)
OS X Mavericks 10.9.4 (13E28)
2.6GHz Intel Core i7
16GB 1600 MHz DDR3
Intel HD Graphics 4000

Macbook Pro:
When I raise the lid after sleeping, the screen comes on momentarily then backs out. If I close the lid and raise it again, the same thing happens. It is sometimes necessary to force quit. Once restarted, there is no problem unless the lid is closed for a short time and the machinge goes to sleep.

Why is my mac book pro mid 2012 display green flickering screen?
Why is my mac book pro mid 2012 displays green flickering screen? I was able to return the screen back to normal after i turn the lid up and down.
Is this a hardware issue ? should i return to applestore since the warranty still valid?It seems like your display is damaged. As your computer is in warranty, take your Mac to an Apple Store or reseller to get the display replaced for free, as it's in warranty

After upgrading my iPad will do nothing except refuse to take a charge display a black screen or a battery red line or the occasional apple logo. Have tried soft boot and hard boot and nothing!,!
Hello there, Victoria.
Great job on troubleshooting on your own. The following Knowledge Base article offers up some great steps to review and additional recomendations:
iPhone and iPod touch: Charging the battery
http://support.apple.com/kb/HT1476
Resolving issues
If your battery doesn't charge, or if your device shows a low-battery image, black screen, or "accessory not supported" alert, follow these steps.
Inspect the connector at the bottom of the phone:
Make sure that there are no bent pins in the connector.
Make sure that the connector is free from debris.
If there are bent pins or debris, please contact Apple Support.
Otherwise, continue troubleshooting.
Make sure that the outlet you're using works.
Make sure that the Apple USB cable and Apple USB power adapter work.
Plug the device in to power and let it charge until your device turns on. This could take between 10 and 30 minutes. If you don't have an Apple USB power adapter, try connecting to a computer's high-power USB 2.0 port (not a keyboard). The computer must be on.
If the device still exhibits an issue, try turning your device off and then on again while connected to power.
If the issue persists, please contact Apple Support.
Thanks for reaching out to Apple Support Communities.
Cheers,

A rundown of what I've tried:
Adjusting energy settings to try to prevent sleep
Pluging the USB keyboard and wacom tablet directly into the laptop (as opposed to a usb hub)
My laptop's power cable is connected
My display (a Vizio TV) is recognized in the System Preferences panel
I'd been using this TV for about a year with my older Macbook Pro (OS 10.5.8), though using a different wireless keyboard and mouse
***Update: The issue seems to lie with the keyboard and wacom tablet. I am trying to use a wireless Case Logic keyboard (with dongal) and wired wacom tablet to wake the Macbook Pro in clamshell mode. To experiment, I tried using my Logitech wireless keyboard & mouse set (also dongal) that I had been using before and it wakes the computer without any problems! However, I really need to be able to use my wacom tablet. If I switch to the tablet after waking the computer using the Logitech keyboard & mouse it works, but once the computer sleeps it won't work anymore. I could keep switching back and forth I suppose, but it's sort of a pain. There has to be an easier way! Any ideas why the wired wacom tablet is unable to wake the computer in clamshell mode?
Thanks!So your keyboard or mouse won't wake the Mac when you close the lid correct? Try resetting the SMC and pram
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery.
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer.
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys. -
I have a Samsung VGA Monitor connected to my MacBook Pro using the Mini Display Port to VGA Adapter. How do I configure the computer so that it doesn't sleep when I close the lid of the computer.

This article may provide some information about your Mini DisplayPort to AVI adapter. Have you tried to connect a different VGA monitor to your Macbook to see if you get the same results?
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
http://support.apple.com/kb/HT3382
18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?
The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/HT1573#5
How can I detect displays?
If the detect displays option is not available, hold down the Option key while you are in the Display pane.
How do I select additional resolutions on my display?
You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.
To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.
I hope this information helps ....

When I close the lid on my MacBook Pro the print on thunderbolt screen is very small & hard to read. If i keep the lid open on the MacBook Pro the print is big and easy to read. How do I prevent this from happening?

iPod nano 3rd gen. Apple logo remains on screen and iTunes doesn't recognise it's plugged in, I can't even turn it off. I've tried to get to disc menu but when I hold the 'menu and select button' it reboots and then doesn't recognise the select and play button to show the tick. I'm helpless.
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 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.

My mac mac book pro w retina display will not go to sleep when I close the lid or put it to sleep.
My mac mac book pro w retina display will not stay asleep when I close the lid or put it to sleep.
I put the computer in my bag and when I open it again the machine is so hot I can almost not touch it.
I am affraid that the hardware is allready fried.
Also when I press a key to restart after it has been idle for a few minutes it often takes up to a minute to wake back up.
This machine is bran new..
What should I do?Try a SMC reset:

I was typing an email to friend. I put the ipad down to answer the door and came back a few minutes later and the screen had gone blank and when I tried to get the message that I was typing back I could not find it. The message contained a lot of text and pictures. How can I find it? I have looked in drafts.
Perform a Reset... Try again...
Reset ( No Data will be Lost )
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear...
Usually takes about 15 - 20 Seconds... ( But can take Longer...)
Release the Buttons... -
Can somebody help me? When i first turned on my MacBook, it never booted up and ultimately the screen went blank.

Will the Thunderbolt Display work when I close the lid?
I have a 2012 Macbook Pro. I'm thinking about buying the Thunderbolt Display, but only if it can simulate a desktop and I can close the lid of my Macbook. I'm asking this because I know it goes to sleep when closed and was wondering if the Display makes it work differently. thanks.
Works great and how I do 90% of my computing.
I use a usb wireless keyboard with the receiver plugged in to the back of the TBD. When the laptop is asleep press the space key once or twice to wake up the display (be patient, doesn't work as fast as you think it should). I use a screenlock password, so enter it and we're working!
One note: if the computer is turned off you can not turn it on from the keyboard. You'll have to open the laptop, turn it on, and once you hear the chime you can close the laptop and you're gtg. -
Screen wont shut off when I close the laptop after fresh install (L512)
So I recently replaced the hard drive in an lenovo L512 with an i3. I've updated windows completely and installed I believe most of the drivers. Everything seems to be functioning perfectly. The only thing is when I close the laptop. The display does not shut off. Is there a driver I am missing? I am running windows 7 professional x64. completely legitimate copy with the original key from the laptop. Thanks for any help!

This only started happening after I upgraded from Windows 8.1 to Windows 10, I don't have a clue why it does it, but if I close the screen on my laptop and open it, the screen doesn't come back on it just stays off but the power light button comes on and the WiFi signal button is on but it is red as if the wifi is turned off, is anyone else having this problem or does anyone know how to fix it? I have to manually hold down the power button everytime I close my laptop to turn it off and then back on and once it is on it works perfectly, but I don't like holding the power button down for obvious reasons. Thank you.Go back to Windows 10, seems HP do not care about releasing up to date drivers for Windows 10, this is despite the problem you report also happening during BETA Testing of Windows 10 over TWELVE MONTHS AGO!

My Brandnew 15 inch Macbook Pro (mid 2012) Crash to Black Screen
My Brandnew Macbook Pro (Mid-2012) just purchased last August 2012, i turned it on and watched some movie online and youtube when all of a sudden, the screen would turn black and the machine would not react to any keyboard or mouse input anymore. All I could do was hold down the power button to turn the computer off.
i really appreciate your ideas about this problem...If it has happened more than once, make a "Genius" appointment at an Apple Store to have the machine tested.
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 bare metal from any of them.) Don’t erase the recovery partition, if present.
*An SSD doesn't need to be zeroed. -
MacBook Pro mid 2012 stuck on grey screen on startup
Hey guys.!
I need an advice from you guys.
I updated my Mbp few hours ago... It asked for a restart , I did after sometime but now while starting up I can't get passed through the grey screen with an apple logo and circle loading sign. Before this showed a loading bar also with it.
I can't figure out is there a problem with it or just takes time to finalise the updating or something .
Would love to get replies ASAP
Thanks,
A fellow MBP user
AakashDid you try Repair Disk instead of Verify Disk? The latter does nothing.
It is possible the drive has failed. It's also possible the drive just needs to be reformatted which you would do were you to try my second suggestion:
Install or Reinstall Lion/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.
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.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.
