T430 Won't Boot - ThinkPad startup screen just cycles

Please help...
Have been using my T430 as usual this morning, all running fine...then...battery died while using it, so went to get the charger, now have plugged in and powered back on, and it will only get to the "ThinkPad" loading screen. It won't get to Windows.
Note. it doesn't "freeze" at the ThinkPad screen, it keeps cycling through it, as if it's going to load or shutdown, but then it comes back to the ThinkPad screen, over and over again.
Have updated the Lenovo Service Center this morning but that's all.
I can press F10 and get into the Bios, but I don't know what to do to get it passed this boot up?
I have no USBs plugged in and plugged nothing into it this morning while using it.

My Ipad won't boot up I am just getting a white apple in the center of the screen?

My Ipad won't boot up I am just getting a white apple in the center of the screen?

Try to reset the device:
Device Reset (won't affect settings/data/music/apps/etc)
Press and hold (& continue to hold) BOTH the Sleep/Wake button & the Home button.
Continue to hold BOTH (ignoring any other messages that may show) until you see the Apple logo on the screen.
Release BOTH buttons when you see the Apple logo and allow the device to boot normally.

IMac won't get past startup screen, no matter what. Pls help?

I just inherited a mid-2010 iMac from a friend. It hadn't been used for months, and now when it is started up, it won't get past startup screen. It shows the 'slot' looking image on the bottom of the white loadup screen, then it's just the apple symbol and the whirly thing going around forever. I've had it going for over half an hour at one point, and nothing changes. I have tried all the different reboot key combos, such as C with a startup disk in it, D for hardware test, command S for safe mode, etc. The only thing which makes any difference at all is using the T key at startup, when I do get the three-pronged white symbol floating around screen.
It is a 21 inch with 500gig, and I believe it's running Snow Leopard. They never had a problem with it before, but now after the months of disuse, it is doing this. Please, can anyone help? Thanks!

I'm not sure if a dead PRAM battery would give you these symptoms, but one possibility is that if the computer was off wall power for months, the PRAM battery, a small coin cell battery that controls certain functions, may be drained and dead.
But, in any case, try an SMC Reset. You must follow the timing for this exactly.
http://support.apple.com/kb/ht3964
And then a PRAM Reset.
Hold down Option-Cmd-P-R together at the startup chime, listen for two more chimes, total three, then release all the keys to finish booting.
You might also try a Safe Boot by holding down Shift at the startup chime. (Cmd-S isn't for Safe Boot, it's single user mode.) Give it much longer to boot than usual, but if it doesn't finish in perhaps 5 or 10 minutes, then you'll have to give up on that.

Lenovo G560 - Issue with won't boot and black screen after HDD upgrade

Lenovo G560 - Issue with won't boot and black screen after HDD upgrade.
What happen: My laptop was working fine, no blue screen issue, no funny business at all. I bought a new SSD Intel 120 GB and thought it would be a good idea to replace the HDD. I shutdown and disconnected the power adapter, waited a couple of minutes and removed the battery. I opened up the back case and replaced the HDD. And put all the screws back and put the battery back in.
Problem: The very first time I turned the power on, nothing happens besides a black screen. I pressed the dvd drive it works and opens up and closes. I waited for about 30 mins and still has blac screen. When I mean black screen, no bios menu, no logo, just a black screen with the fan sound on.
I have tried these:
1. Unplugged everything - battery, adapter, and pressed the power on button for about 60 seconds, nothing, the laptop turns on with the LED display on for both on and battery LED's. But nothing but black screen, no sound of windows loading just the fan and black screen.
2. I tried putting back my old 2.5" and nothing but black screen.
Thoughts and suggestions?
Solved!

My iMac won't boot past grey screen and it didn't come with a os x disk

My iMac won't boot past grey screen with apple. I've tried booting in safemode but that didn't help and my iMac didn't come with a os x disk.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
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.”
b. 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.
c. 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 either of the techniques in Steps 1b and 1c 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 you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
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, or if a firmware password is set, or if the startup volume is a Fusion Drive or 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 10. 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
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 10
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 11
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 12
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.

Oh, shoot! My MacBook won't boot! Silver screen is all I see!

Oh, shoot! My MacBook won't boot! Silver screen is all I see

Try a PRAM reset:
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.
Any unusual noises coming from it?

Mid 2010 MacBook Pro won't boot past blue screen

I've been having problems booting up my MacBook. I can't get past the blue screen. It went from booting slow at the grey apple logo screen to not booting up at all. Is it a problem with my hard drive? I also have boot camp running as well, but I can still see the boot camp drive for windows and my OS X drive, as well as my installation disk when I have it inserted when I hold the option key at start up.
I'm still able to run windows on it without any problems when I pick the windows drive. I tried different methods from different forums but I'm just not getting through. I tried holding 'c' to boot up from cd and I let it run over night but it never got past the grey apple screen with the gradient wheel (still spinning). I had already used time machine to back everything up before this happened since I was able to boot up properly (but slowly). Can anyone help? It's driving me nuts, and I can't remember what os/firmware version I'm running.

n your signature you said you are running 10.6.3. So let’s assume you are running Snow Leopard.
It sounds like your diagnosis of disk problems is correct. The OS X partition may be corrupt.
Try booting in Safe Mode.
http://support.apple.com/kb/HT1564
Try again to boot in normal mode.
If it will boot in Safe Mode but not in normal mode then you could have some 3rd-party software preventing the boot or you could have a corrupt disk or OS.
Boot as from the startup manager (Boot - option) and then select the installation disk.
Hopefully that will work better than starting with the Boot-C option.
Then try to repair the system disk.
Start the Disk Utility.
Perform the steps in http://support.apple.com/kb/PH5836.
If it repairs OK but still won’t boot reinstall OS X.

Macbook Pro won't boot past grey screen with Apple logo and then shuts off

This is a long story...
This morning, I would turn it on and it'd go to the grey screen with the Apple logo for a few seconds and then go to the icon that is a circle with a line through it. After reading online, I was able to boot it up in Safe Mode. I messed around a little bit in system preferences thinking I could fix it on my own, not really knowing what I was doing (I'm a *******). I went to Startup Disk in Preferences. I chose the MAC OS X, xxxx and then clicked the lock to prevent further changes and then clicked restart.
Now when I turn on the macbook, it goes to the grey screen with the Apple logo for at least two-three minutes and then just shuts off. Won't boot into Safe Mode now. Please help. I already tried the Command-Option-P-R keys trick like five times.

If you have a full retail DVD for 10.6 you can boot from that by holding the C key during startup...but you will then be in install mode if that is what you want to do. At least go ahead and see if it will boot ok from the 10.6 disk and then you can decide what you want to do further.
Apple does not have 10.5 for sale anymore from what some other users have said on here so if you want to go that route you will have to find a copy for sale such as from eBay or one of the Mac resellers.
Before taking the machine to someone, try booting from 10.6 and see if that works...that way you can narrow down problems the machine may be having.

PowerBook G4 won't boot past blue screen

I've read a couple of posts with similar problems. The jist is, I did a security update/restart earlier and now my laptop won't boot past the blue screen after the white screen with the gray apple. I think I'm on Mac OS 10.4.11 but I had it on auto-update so that could be incorrect.
I've booted from the install disk and run a diagnostic from the First Aid bit in the Disk Utility. It says that there are no errors found and the S.M.A.R.T. status says "verified" as well. It won't let me boot into Safe Mode (although, I could be doing that wrong as I'm not exactly clear on how to do it - pressing S doesn't seem to do anything, but if I press Command + S it takes me to a text listy thing and I've run the "fsck -f" system check (which seems like the same as the disk utility check?) from there and also gotten the "volume is ok" message. There was also a suggestion to run some kind of diagnostic after booting with the D key from the install disk, but I was never able to get the disk to boot from the D key, only the C key.
I'm sure that this is kind of the "same song, different verse," kind of post, but I've not read about volumes registering as okay. I'm a little wary of a archive-and-reinstall as I've not ever done that before (so, if that's the suggestion you have, I would really appreciate loads of specifics on how that works so I don't mess up!)
I've read in several instances suspicion of a hard drive problem but I've not had any slow downs or any crashing. I did travel to the UK for about 10 days, but I didn't even change the time zone on my laptop while there, so I don't think that's it (but I suppose it could be.)
Lastly, I did recently replace my keyboard. A few keys had become non-responsive so I replaced it and have had the new keyboard for a bit over a month.
Suggestions? Ideas? Sorry if it's a repeat post -- just felt like the circumstance was a teensy bit different. And also, thanks very much for any info you can give.

Linsey:
If you can boot your computer into Firewire Target Disk Mode and you have access to a second Mac that supports firewire, you may be able to back up items that have not been backed up previously.
If you are able to back everything up successfully, and you have tested your backup to be sure it is sound, then we can proceed with re-installation of the OS. The best option is to completely reformat and erase the HDD and then install the OS from disk. (I will post complete step by step directions). This will enable you to start with a clean slate/HDD. Your other option would be to use the Archive and Install option. Think it over and let me know how you want to proceed.

Macbook won't get past startup screen?

I dropped my macbook, approximately from a 3/4 meter height. It beeped 1-5 times (i think)? Then froze. I Turned it off, then switched it back on, and it went through the usual startup phase, except it wont go past the loading screen and won't boot up in single user mode, help me please?

You may have damaged the disk when you dropped it. Here are some steps to diagnose that and possibly repair the filesystem. (It may be some other problem but this is a good place to start.)
Reset SMC:
http://support.apple.com/kb/HT3964
Boot in OS X Recovery Mode overview.
    http://www.apple.com/osx/recovery/
   If it boots in standard recovery mode then
   at least part of your internal disk is working.
   If it boots in network recovery mode then your internal disk may be damaged
   but the rest of you Mac may be healthy.
While in Recovery Mode check the S.M.A.R.T. disk status, try to repair the system disk (Macintosh HD).
If that does not fix the problem then reïnstall OS X.

MacBook won't go past startup screen

My MacBook won't go past the startup screen.
This happened after I tried reseting my battery because it was not being recognized since it was drained completely. After removing the battery and re-inserting it was still not being recognized. So the support website advised to try downloading the latest update. However, before downloading the last item, it showed a message saying that there had been an error in the download, to go ahead and erase the current download and try again. However, when i clicked "ok" on the error box, it automatically went to re-start and I have not been able to go past the gray screen with the apple...the waiting circle just keeps going round and round.
I have tried to start it pressing the c key and the shift key but it did nothing. I then tried to start it with disk 1 and it does nothing either, plus the disk will not eject either.
Please help!!! what should I do???
Thank you so much for your time to help me with this.
MacBook 1,1 Mac OS X (10.4.9)

To eject the disk, hold the trackpad button down as the machine restarts.
Is your data backed up?

Macbook won't boot up - grey screen only

Hi,
I have a core duo MacBook from summer 2007.
All of a sudden the MacBook won't boot up. The battery is fully charged and AC adapter plugged in (same symptoms if not plugged in). The following occurs upon pressing the power button:
1) Start-up chime sounds
2) Can hear hard drive and fans start up
3) Screen turns grey
4) Nothing happens (screen still grey)
Thoughts? I tried resetting PRAM and PMU with no changes.

I have the same problem, just the grey screen and tried
- resetting PRAM (second chime, so this should be OK)
- Safe Mode (just the same)
and pressing Option (or C) to choose the Mac OS X Install Disc gives me the wonderful cursor which can be moved by moving the mouse. No harddisk and even no Install DVD are displayed on the screen.
Also The Apple Hardware Test (by pressing D) doesn't get further than the, now familiar, grey screen.
I pressed the keys with different keyboards, with the original white keyboard and with the aluminium keyboard.
As I've tried everything, I think there's something seriously wrong. Does anybody have some last tips that I can try?

G4 Power Mac won't boot past gray screen

I have a mirror door g4 power pc that had been having some issues with not turning on, and after testing the power supply, it failed miserably. We placed a refurbished power supply in it from a company in New York and the computer was working wonderfully. I went on a cruise last week and went to turn the computer on for the first time in a week and a few days. The CPU turns on, the unit chimes, the fan turns on and the computer starts to boot up, but it won't boot past the gray apple logo screen.
Actually, the first few attempts to boot it resulted in a blue screen with gaint apple logo and spinner; it wouldn't advance further. After several restarts and resets, I got it to come up into the normal gray screen. On several attempts it wouldn't boot further than this. On two occasions now though, it has moved past the gray screen to normal operation (it takes about an hour for it to get to that point though) but with some kind of errors. I get the side bar, but the gray panel on to with "file" ect is gone and my HD icon never comes up. The icons on the sidebar do not respond when clicked.
The computer will not boot from the OS X disc.
What's going on, hard drive? Virus? Something else?

You likely have hard drive directory issues or worse.
Virus is just a hopeful whimsy.
No virus.
I hope that you have a backup of your data.
Try a Safe Mode boot. This forces system repair of the directory (if possible).
Hold Shift while starting to enter Safe mode. Be patient, as it can take several minutes to complete.
Failure to boot to the OS X disc is not good. A severely damaged drive can prevent boot while connected.
Disconnect your boot drive and try booting to the OS X disc.

Elite pavilion m9040n won't get past startup screen

For the past few weeks, my computer has been unable to load past the initial startup screen( blue hp screen) . The screen goes to a black screen with a blinking cursor and then after hearing what sounds like a click and a loading sound it restarts over and over. After several attempts running startup repairs , I am able to get to the hone screen however it freezes every few minutes or so. I'm inclined to think this may be a hdd issue because I have been receiving the black screen message : A disk read error has occurred. Press ctrl+alt+delete to restart.
I should add that I haven't changed any hardware or software prior to this problem.
Any help would be appreciated

Hello Sosa70, When the system completes the POST (Pre Operating System Test) successfully, it turns control of the system over to the operating system, and you would see the black screen with the blinking white cursor.
Sometimes when the operating system has become corrupted, it cannot boot into the Windows desktop.
It is also possible that the hard drive itself has become faulty. Since you mentioned you performed the hardware test and found no errors, you may just have a corrupted operating system.
