New Macbook Pro does not start up after updating...HELP!!!

Hi,
My new Macbook Pro does not start up after it got updated. The first time I used it, it was perfect. I updated it and restarted it when it told me to but it doesn't boot. It shows an apple and a spinning circle when it turns on but that's it.
Can somebody please help me?

You should probably post your question in the MacBook Pro discussions:

MacBook Pro 17" (Late 2007) not starting up after battery calibration (depleted)

Hi, I have spent most of today skimming through the advice given on these forums, but to no avail. I cannot power up my MBP. Since it is Sunday, I will give my best to find every piece of "soft" advice to try before giving up my daily workhorse to the official Apple Support.
Machine specs:
MacBook Pro 17" Hi-Res pre-unibody (2007)
Second battery - original bloated about a year ago (lasted 4 yrs! of continuous use)
SSD primary, HDD secondary drives
6GB om RAM
2.4GHz C2D
MacOS 10.6.8
Logic board replaced a few years back with faulty graphics (re-call).
This is what happened:
I decided to recalibrate my MBP (replaced, non-original NuPower) battery over the weekend.
I'm using my laptop at home and at the office, plugged in mostly. So it was advised to perform this procedure for the sake of a healthy battery.
Dreained it to the state of sleep nd then waited for the sleep light to go off.
A couple of hours passed after that when I returned to my desk and plugged in the adapter.
The LED went on GREEN (weird, I thought, but hoped it just did not pick up the completely drained battery right away).
Let it rest with that state for several hours. LED remained GREEN at all times.
Tha laptop sat still on the desk the whole time...
This is what I tried:
Unplugged, took battery out briefly, replugged - GREEN indicator.
Tried another adapter (60W instead of the original 85W), that adapter showed green as well.
Tried my AC adapter to charge another MacBook - charged fine, AMBER light.
- THIS MEANS the problem is with my MBP unit (incl battery).
Unplugged, took battery out, held the power button for 5secs (SMC reset), reassembled - no improvement
Tried all key-combos, held power button for 10secs
Took the battery out and tried to bott with plugged adapter, this normally works fine, but now nothing - no sound whatsoever
- THIS MEANS the issues is not with the battery, it is with the power management.
Sad thing is, that if it is the motherboard somehow that got damaged by itself, it means the end of this fine and capable machine. It is not worth the investment of a replacement motherboard and buying them from ebay is not a sustainable option
Tomorrow I will swap AC-adapters and batteries with an identical model of a friend. I will let you know.
I expect little you can help me with, but for future reference, the story might prove useful for similar cases. I was upset and surprised mainly because of the timing - not powering up after drained battery during calibration process.

Dreained it to the state of sleep nd then waited for the sleep light to go off.
A couple of hours passed after that when I returned to my desk and plugged in the adapter.
Did you wait 5+ hours? Per article - http://support.apple.com/kb/PH7261 "After your computer goes to sleep, turn it off or allow it to sleep for five hours or longer."

MacBook Pro fails to Login after battery ran out.

Hi!
I have been working on my MacBook Pro (Retina 15") for the past few hours, untill it ran out of battery. I then walked to my power cord and pluged it in. The MacBook boots and comes up with the login screen. When I log in, the screen goes black and it reboots. This repeats untill I boot from my Recovery USB and repair the MacintoshHD Volume (and reboot a couple of times).
Is anyone else experiencing this?
Thanks

Portables with built-in batteries
Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure outlined in this article.
http://support.apple.com/kb/HT1490
Yes. The computer should be sent to Apple to have the battery checked out.
Battery is in warranty for 1 year from the date of purchase. It is wise to bring any hardware related
issue to the attention of Apple.
Best.

MY macbook pro would not start up after PRAM reset. HELP

I got the spinning beach ball of death again. And then I held the power button until it turned off. turned it back on and then it had the spinning loading wheel underneath the apple logo upon start up. I waited 10 minutes before holding down the power button again. Then I tried to reset the PRAM. After I thought I did it right. whenever I try and start it up it loads a grey screen that says. "you need to restart your computer. Hold down the power button, wait until your computer is off then press the power button again" and it says this in a few different languages. I need help -please. Thank you. I'm running mac os x leopard version 10.6.4

It sounds like your are suffering a Kernel Panic. I would recommend reading this article about KP's and how to trouble shoot them. If your machine is under warranty or if you have AppleCare you can bring it in and Apple can help you solve the problem.
Resolving Kernel Panics
In addition here is an Apple Article that helps educate you about the problem.

IPOD will not turn on, after power ran out and charging for two days.

Slept off while using my IPOD, noticed the next morning that the battery was flat, i charged the IPOD, for one day, try to turn it on nothing happened, charged it for the second day, same thing, it refuses to turn on. Please i will like tips and help on how to go about resolving this problem. Note a friend had same problem and had to charge hers for one days before the IPOD turned on.

If not this:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem. A trick that works frequently with iPhones:
Settings > AirPlane Mode ON, Do Not Disturb ON
Power down and wait 5-10 minutes
Power up
Settings > AirPlane Mode OFF, Do Not Disturb OFF
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.
Apple Retail Store - Genius Bar
Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

My MBP will not start up after restart

My MBP (late 2011 running 10.8.something - receintly updated) will not start up after I had to do a restart to install Blackberry Desktop software (for my wife, I promise). It chimes, gets past the grey screen with the Apple logo and then just sits on the login screen but with the background only, no account or anything. My mouse pointer is there and moves but nothing else. Anyone have any idea?

Reboot holding the Shift key down on a wired or built in keyboard, this is Safe Mode and will disable the at boot kernel extension file that Blackberry installed.
When you get in uninstall the software using their uninstaller. Then reboot normally again, visit their website for a update if there is one.
Blackberry/RIM software has been causing issues around here lately.
If your machine refuses to boot normally again, then run through this list 1-8,, by #8 your machine should be booting normally again.

Ipad2 will not start ,just dead.battery is charged

Ipad2 will not start ,just dead.battery is charged

Mine had a similar thing happen after a few weeks, except that mine wouldn't even start until I'd done the reset - I havn't had a problem since. Unless you start getting regular problems I wouldn't get too concerned. And it may have been caused by apps that you've downloaded, so it may not necessarily be down to the operating system or Apple's apps - but no code is bug free.

MBP not starting up past loading apple

I was just about to finish up on my Macbook Pro the other night when it prompted me to reinstall software updates, and after wavering it for a little while I decided it might be a decent idea to finally do it. After about Five minutes of waiting wearily and the updates not progressing as fast as I wanted it to, I shut the lid and went to bed.
When I woke in the morning to check my emails before work, I was confronted by the problem of my MBP not starting up beyond the Apple with the loading thing underneath. I've tried resetting P-RAM, put the install disc in and starting up holding Option, and also holding C.
I can't really think of anything else and it's a hard task for me to take my laptop into town with the monsoon we've been having lately.
Any suggestions?
Help is much appreciated,
Peace.

Not the brightest thing to do while the computer is updating. What did you think would happen? You could have just let it run and gone to bed. Not knowing which updates you are referring to I would hesitate to guess that you now have directory issues or worse. So, your options are:
1. Run Repair Disk from Disk Utility while booted from your installer disk. If it won't repair the disk;
2. Use DiskWarrior to rebuild the directory. If that wn't do it;
3. Do an Erase & Install of the OS.

MBP doesn't restore after battery depleted

I have a 2008 13" Macbook pro. I have this caffeine utility which is really handy if I want the screen to stay lit but sometimes I forget to plug in and my battery dies. It used to restore after my battery ran out (that gray screen with the bar near the bottom) but now it either hangs when it gets to the middle or I get a message in a box telling me to hold the power button down and restart.
I know I should just be more careful and not let my battery die but it's a real bummer when I lose what I was working on.
Would this be resolved by buying a new battery?

The best solution is to invest in a backup drive, and backup with an application like Time Machine. Even if your HD explodes, you have a backup.
Getting a new battery may not be necessary, so long as you keep track of your battery. Download a free app like Coconut Battery. It installs as a desktop item, and you can consult it at any time.
Also, consider using your machine while it's its plugged in. This saves your battery for when you really need it.

Same thing happens when i click restart.
No difference when i run it in Safe mode. And it won't let me create a new profile either. Is there anyway else i can extract my bookmarks? This is driving me crazy!

Did the crash reporter send any crash reports? 
You can see the crash reports in this folder:
"C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Crash Reports"
See: http://kb.mozillazine.org/Breakpad
See also [[Firefox crashes when you open it]]
Create a new profile as a test to check if your current profile is causing the problems. 
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]] 
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" 
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files) 
See http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox 
If that still causes the same problem then do a clean reinstall and remove the Firefox program folder.
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data when uninstalling.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Yes, your battery is likely toast and in need of replacement. Not much else for troubleshooting here. Sorry.

2007 Mac Book pro Shuts down at startup attempt. Tried reloading OSX and will not start up after that.

My Mac Book Pro started having issues. I tried to relaod the operating system and it worked for a moment. When I tried to do a time machine back up it failed.
Now itr Shuts down at startup attempt. Tried reloading OSX and will not start up after that.

Dr.Conga,
did you try to do a Time Machine backup from your MacBook Pro, or a Time Machine restoration to it?
Are you trying to reload your current version of OS X (10.7.4, to judge from your signature), or are you trying to reload the version of Mac OS X that came on the grey installation DVDs that originally came with your MacBook Pro?

My Mac Book Pro will not start up. I ran the AHT and received the following error: 4SNS/1/40000000:Th0H-90.750. Anyone know what this means?

I have no idea how much it will cost to repair. I don't even know what the exact problem will prove to be. It may be quick if it isn't a motherboard problem. I just don't know. Take it in for a service diagnostic, then they can tell you what is involved.
