My computer wont start up. It was fine when I shut it down the night before.

How come my computer will not power up?

Are you able to provide more information?
Such as is the mag safe LED on? if so what colour?
have you made any hardware or software changes?
Are you able to press control, command and power at the same time to see if have any results?

Before Firefox 4, each time I started the computer, it would load the windows I still had open when I closed down the night before. This has disappeared. Can I restore this?

Before Firefox 4, each time I started up the computer in the morning and clicked on Mozilla Firefox, it would load up the windows I still had open when I closed down the night before. Very handy! How do I restore it this terrific time-saving feature?
Thanks

Is there a solution to this? Could someone post a link?

My phone wont start up at all, even when it is connected to the computer or dock. what's wrong with it?

Please help.

Even if it's plugged into the wall charger, it can take 15-20 minutes of charging before the iphone may turn on. So if ti dosen't turn on after the reset brad suggested, then I would suggest leaving it plugged in for 20 minutes and trying the reset again.

Computer wont start in any mode

my windows xp computer was just working this past week till i restarted it and it said that i needed to download a antivirus and i have one it just wont open up in safe mode or the regular mode so now the computer wont start at all and now i was wondering if i could get a new computer tower and plug in my netgear wireless G router into this new computer tower and have internet and everything

plugging in a new tower should work. its like a whole new computer with the same screen and stuff as before. mine just got a bad virus and it wont start either. might have to do the same thing.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

My computer wont start!

My computer wont start and i dont know why!

If a SMC reset fails to bring life to the MBP, make an appointment at an Apple store genius bar for a free diagnosis.

I assume you have a functioning power adapter attached to your MBP.
Ciao.

Computer wont start up

So today I went to start working on my LR and FCPX projects and when I got to the office for no reason at all my computer wont start up.
I've tried holding the "shift", "command" & "V" key from what I read to do, and now I get a black screen which pretty much said what the grey screen said.
This is the strangest thing.

According to your profile your Mac has v10.8 installed.
Startup your Mac while holding down the Command + R keys so you can access the built in utilities in OS X Recovery
From there you can repair the startup disk if necessary or restore OS X.
Hopefully you had all your important files backed up in advance just in case.

Computer wont start after apple logo shows up..

I have a friend who owns a MBP 13 Late 2012, and suddenly he explains computer after he shut it down, the gray screen shows up and apple logo too, but never enter to the OS.
I have had this problem with a 2009 iMac in the past and they told me it was a problem of humidity and or dust, and so they had to change the Motherboard.
Have any one experienced this ?
I even did the PRam reset several times with no luck, actuallu It wanted to start (get into the OS) but MBP kept with little spinning circle.
Any thoughts?

So I received the MBP, and did the Command R to get to recovery mode, and after the World spinning, I got this Message: www.apple.com/support and then -5010F ... (image 1)
Power it off and reboot it with OPTION key, and selected Macintosh, and after that the Apple logo shows up with the little circle spinning infinitely.
What do you think? Doesnt go any further than this: (image 2)

This is probabaly caused by the resume feature. When you log out, uncheck the box that appears.

So i have some open work from the night before on my computer and left it on, closed the top, the computer restarted it's self and lost all the work to what was added.....where can i find it....was it auto saved?

If the application supported auto-save, yes, if not, then no.
If you were creating a mail message, it might be in the drafts folder of the e-mail program.
What evidence do you have the computer restarted itself? Did the Apple logo come up?
