MacBook Pro starts then the apple logo comes up and it looks like it want to continue then a white screen comes up and stays
I purchased a refurbished MacBook Pro (MACBOOK PRO APPLE MD385LL/A)
I did go to newegg and purchase / install 16 GB of RAM
It worked fine for the first week or so, now I shut down and when I restart - it starts - then the apple logo comes up and it looks like it wants to continue - then a white screen comes up and stays.
This just started.
I got this fix from on line
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Macbook if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
It works most of the time How do I fix this permanently?
Can you try putting in the old RAM to see if the problem persists?

Macbook pro boots past the apple logo then gets stuck on white screen
I have a macbook pro that won't boot all the way. When I turn it on it will go to the apple logo, and proceed past it then get stuck on a white screen. If you leave it on this white screen after a little while a grey ribbon will come across the top with little white squares and rectangles. The picture comes up like this [IMG]http://i863.photobucket.com/albums/ab198/helmerfan/60350C7C-C4F6-4040-A081-388B5 4FF77ED-2239-00000184408A3AD1.jpg[/IMG] (not sure if this will work) http://s863.photobucket.com/albums/ab198/helmerfan/?action=view¤t=9F4716F1 -3DE1-4799-A87A-9E8E5E918EF2-3530-00000378A8CDCED1.jpg#!oZZ5QQcurrentZZhttp%3A%2 F%2Fs863.photobucket.com%2Falbums%2Fab198%2Fhelmerfan%2F%3Faction%3Dview%26curre nt%3D60350C7C-C4F6-4040-A081-388B54FF77ED-2239-00000184408A3AD1.jpg
I took the hard drive out and tried to start it up with just the os x disk, and still got the same thing. I took the disk out and the hard drive out and then got the folder with the question mark. Someone said that it sounded like a graphics card issue, and if you all agree do you think that that would be something that a reflow would fix? Thanks for the input guys.I have a macbook pro that won't boot all the way. When I turn it on it will go to the apple logo, and proceed past it then get stuck on a white screen.

My iPad mini keeps turning itself off and then the apple logo keeps flashing constantly, i have charged it fully and restored it many times. what can i do?
If you have restored to factory settings and started as new, there is nothing more that you can do on your own. Make an appointment at an Apple Store and ask them for help. You might have a hardware problem and the Apple Store techs will be able to determine that.

My early 2011 MBP 13" does not recognize my Sandisk 16GB 45MB/s Extreme Pro SDHC card. I went to the Genius Bar and we tried it in all the MacBook Pro's in the Apple Store and NONE could recognize the card. However, iMacs did. Any suggestions? Genius behind the Bar suggested wait for LION OS X release...
You really don't need to post multiple times, you will get attention eventually.

Have an iPod touch 4th gen. It is completely charged, but once I disconnect from a power source it shuts down and then the apple logo just keeps reappearing. I have restored via iTunes and reset all the settings. Any suggestions?
If you restored to factory settings/new iPod via iTunes (Not via Settings>General>Reset>Erase all Content and Setting) and still have the problem that indicates a hardware problem.
Make an appointment at the Genius Bar of an Apple store..

I haven't been able to find any answers that solve my problem. My Ipad will not leave the Apple logo. I hold both buttons and the screen goes black and then the Apple logo immediately pops back up. I can't get the red slider screen at all. No matter how many times I hold down both buttons the screen goes black and then the Apple logo pops right back on.
Before you do anything else, try charging via a wall outlet for a while, since its off. Then try turning it back on.
When you put the device into recovery mode it allows you to restore the device when no other options work. You do risk losing everything currently strored on the ipad itself. Hopefully you've performed regular backups either via itunes, icloud or both. Evern if you have synced content to either of those, you may not lose everything. All previous purchases have been saved in the itunes and app stores, so you can dowload them again.
while the ipad is off, press and hold the home button and plug the usb cord into the ipad. You should see a message pop up on the itunes window on your compoter screen that state it has discoverd an ipad in recovery mode.
You should now be able to restore -
My iPod is stuck on the startup screen, showing just the apple logo. Has anyone had this problem before? If yes, then how did you solve it?
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.

And if you check the link I posted, you'll find information on troubleshooting:
Check your USB connections
Related errors: 13, 14, 1600, 1601, 1602, 1603, 1604, 1611, 1643-1650, 2000, 2001, 2002, 2005, 2006, 2009, 4005, 4013, 4014, or “invalid response."
If the USB connection between your device and computer is interrupted, you may be unable to update or restore.
To narrow down the issue, you can also change up your hardware:
Use the USB cable that came with your device, or a different Apple USB cable.
Plug your cable into a different USB port directly on your computer. Don't plug it into your keyboard.
Try a different computer.
If necessary, resolve any further issues with the USB connection, then with your security software.
If you're still seeing the error message, check for hardware issues by following the next section.
