When I press the power button, my screen turns gray with the apply (like it's going to turn on) but then just goes black and turns off completely. What should I do?

Thank you so much for any help you can give. I was informed the solution may have to do with "recovery mode" and "disk utility." If you need more information, please let me know. Thanks again for your help.

Hi there Colleen821,
I would recommend taking a look at the troubleshooting steps found in the article below.

Kernel Panic: You need to restart you computer. Hold down the Power button until it turns off, then press the Power button again.

I apologize for writing a book, but I think explaining the full story may possibly get me a correct answer. I hope that someone can give me some insight as to what is the problem with my MacBook Pro. I have a MacBook Pro (15-inch Early 2008), model identifier: MacBookPro4,1 running OSX Lion 10.7.5 with 6 GB memory. My wife first noticed a problem with the display. Every so often it would get fuzzy with jumping lines going across the screen making it vitually unviewable. The final time that incident took place the computer froze which required holding down the power button to restart the computer. The computer started up to the point of the Apple logo and the spinning gear for quite some time until the screen darkened from top to bottom displaying the following message in five different languages: "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again." I have read other blogs and support communities where people get the message intermittently, but my computer would not go past that point no matter what. Through research and the Apple Store I was told that this is a Kernel Panic. The so called "Apple Genius" at the local Apple Store was unable to get the computer to boot past that point even with his gadget. It would not startup in recovery mode, safe mode or off of a disc. I forget exacty what he told me, but he said it was getting past the first two startup steps, but it would not get past the third step which is to mount the desktop. He guessed that it may be a problem with the hard drive; a loose wire or something or other. I disconnected the hard drive completely and took it out. Everything appered to be connected properly. Then I installed it back correctly, but it did not solve the issue. So I guess I disproved his theory of a loose wire... I purchased ProSoft Data Rescue 3 and connected my MacBook Pro to another Apple computer using a firewire 400 cable. I was able to get everything I needed off of the hard drive. I did some more research and I decided to restart the MacBook Pro in verbose mode (holding down the command button and V button). The computer magically started up!!! I was upset that I wasted my money on the ProSoft Data Rescue 3. I managed to take additional items off of the computer and back it up on to an external hard drive. After some time the computer froze. I repeated the power button process to restart and received the same kernel panic. I managed to get the computer to startup approximately six or seven more times via verbose mode; each time the computer staying on for a shorter amount of time before it would freeze. I managed to run Disk Utitlity. I performed first aid to fix the hard drive and it said that the hard drive appeared to be fine. After first aid I erased the hard drive and booted off of a Lion disc to perform a clean install or an erase and install. Lion installed until the progress bar got the the end where I received a message that there was an error installing Lion, please try again. Each time I attempted to install the software I would receive the same message. Eventually the computer would not boot from the Lion disc. I went back to the Apple Store and the Apple Genius was able to get the computer to boot off of his gadget where Lion istalled completely. I set up the computer as a new computer. He said that he partitioned the hard drive as DOS and then back to Mac OS Extended (Journaled) which would get rid of any errors the drive may have had. He guessed that the problem was the hard drive, but was not exactly sure. When I brought it home I installed all of the software applications I had on it previously. Approximately three days later, which may have been the fifth of sixth time starting up the computer, the display became fuzzy again and the computer froze. The computer did restart once and I was able to retreive a "log" which I have pasted below. After if froze for the second time it restarted once using verbose mode and froze almost immediately. After holding down the power key to shut it down and then restart; I received the same kernel panic after the Apple logo and spinning gear which put me right back to square one. Now the computer will not boot via any method. It freezes at the end of verbose mode which forces you to hold down the power button to shut down. I also read that poorly seated ram may cause this issue, but I removed and installed the ram multiple times. I even purchased new ram from Other World Computing (Mac Sales) 6 GB, but that did not make a difference. I think I may see six possible problems on the verbose screen mode, five errors and one warning; I will type them out here:
1. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key $Num (kSMCKeyNotFound)
2. SMC: :smcReadKeyAction ERROR: $Num kSMCKeyNotFound(0x84) fKeyHashTable=0x0
3. SMC: :smcInitHelper ERROR: MMIO regMap ==NULL - fall back to old SMC mode
4. WARNING - ACPI_SMCCtrlLoop: :initCPUCtrlLoop - no sub-config match for MacBookPro4,1 with 8 p-states, using default stepper instead
5. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key MOTP (kSMCKeyNotFound)
6. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key BEMB (kSMCKeyNotFound)
I was hoping that someone could read my log to ascertain wether or not they see a problem that stands out. I was also hoping that someone could tell me if verbose mode provides any information that may be wrong with my computer. I just hope that someone can give me some insight as to what may be wrong with my computer. If it is the hard drive I will easily replace it, but I want to make sure that is the problem first before I waste money on a hard drive or anything else. Please let me know if anyone requires any other information from me.
Thank you!

I had already written a book and I did not want to bombard people with more information, but in my previous research I did come across the major issues with the NVIDIA card. I also was well aware that Apple offered a replacement program that ended in December of 2012. I was going to add that in my original post, but I discounted that theory because I put my faith in the so called "Apple Genius" when I made my second trip to the Apple Store. I brought the NVIDIA card issue to his attention and asked him if he thought that may be the problem, but he said no. He said if it was the NVIDIA card that the screen would be completely black and there would be no startup chime. When I experienced the screen issues I thought it was a problem with the NVIDIA card or the logic board. I asked myself, how can a flawed hard drive cause the screen to act funny.
nbar and Rick Warren, I thank you both for your help and insight; people like you are the real "Apple Geniuses." I was hoping there was a way I could wipe the hard drive before I dumped the computer or attempted to sell it. I guess I will look into purchasing a new machine when I have the funds. Again...thank you both!

Whenever I connect to network from datacard. My system show as message "Restart your system.Hold the power button until system turn off"

I have purchased new MAC Book Pro recently. When connect to net using my datacard, net start's working after some time system fire a message saying that "Restart Your System. Hold power button until system turn off". I have configure network setting too even i am facing the problem.
Please suggest me were I am going wrong.

Thanks,

I had already written a book and I did not want to bombard people with more information, but in my previous research I did come across the major issues with the NVIDIA card. I also was well aware that Apple offered a replacement program that ended in December of 2012. I was going to add that in my original post, but I discounted that theory because I put my faith in the so called "Apple Genius" when I made my second trip to the Apple Store. I brought the NVIDIA card issue to his attention and asked him if he thought that may be the problem, but he said no. He said if it was the NVIDIA card that the screen would be completely black and there would be no startup chime. When I experienced the screen issues I thought it was a problem with the NVIDIA card or the logic board. I asked myself, how can a flawed hard drive cause the screen to act funny.
nbar and Rick Warren, I thank you both for your help and insight; people like you are the real "Apple Geniuses." I was hoping there was a way I could wipe the hard drive before I dumped the computer or attempted to sell it. I guess I will look into purchasing a new machine when I have the funds. Again...thank you both!

Charger led turns green as I press power button, won't turn off

My MBP is turned off. When I plug it in, it's charging and the led is orange. The battery indicator LEDs work as well.
When I press the power button to turn it on, nothing happens, except the led on the charger turning green until i stop pressing the power button.
I tried an SMC reset, didn't solve anything.
What could it be?

Run an Apple hardware test. Perhaps that might offer a clue:

Is there a way to adjust the Scroll bar? Because when I press the arrows key once it goes straight to the bottom of the page rather than going down gradually.

Before when I pressed the arrow key to navigate up and down the screen it would do it gradually. After I up graded to the current version it now skips down to the very bottom of the page.

My nano 6th generation power button will not turn off

My Nano power button will not turn my I pod off anymore. It'a 6th generation.

You can either do an out-of-warranty replacement at your nearest Apple Store for $65/$75 USD depending on the size of your Nano or have a 3rd party replacement of the switch.

Intel iMac 20" 2.4Ghz screen goes black and shuts off on startup.

After pushing power button, hear dong, see gray screen with apple and then see horizontal bar below apple breifly and then shuts off abruptly. Any thoughts?

Good news.
After further research on the Internet, and going through what was happening to my screen, I decided to change the screen power supply - not easy unless you have a spare one. I called the local Apple store and sked if I could borrow one for a few days, and the answer I got was a yes.
Since replacing the power unit for the Apple HDD cinema screen all seems to be well. Which is great.
I do have a few questions however;
Why can't you buy a replacement power suppply instead of spending £900 on a new screen?
Why wasn't this checked by the Apple technicicians when they were looking at the problem?
Hopefully this will help someone else, and avoid the frustration that I have experienced with Apple.

I have just now tried the Reinstall via iTunes, about 20 into the download, the iTunes logo on the phone disappeared, and the Apple Logo appeared again,,, I waited until the iTunes stated that the download had finished, and the install was in progress,,,
Nothing happened, still the Apple Logo was visual on the screen, iTunes never recognised the phone which it was on my iTunes account previously,,,
Still just a bunch of lines, maybe 5 or 6 so small writing,, I personally can not read what it is telling me, someone said it reads, incorrect shutdown,,,????????

I tried plugging it into usb port, still nothing.It won't show up on my computer or turn off. Just sitting here with a white screen. What should I do? HELP.Somebody ? Plz ! ! !

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- 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.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Hi I have a pavilian dv6 which the screen goes black and shuts off .the comp gets very hot

cooling fan not cooling laptop

Hi,
It's always worth trying a Hard Reset as follows.
Shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery, plug in the AC Adapter - see if the notebook will start and whether the fan is now running.
If the fan is still not running, try using a can of compressed air to clean out the ventillation slots, particularly those near the fan - see the HP document on the following link.
http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c01657439
If the fan will still not start, you're going to need further diagnosis of the problem which may well involve having the fan assembly replaced.
If your notebook is still under warranty, contact HP and arrange for it to be repaired - you can check your warranty status Here.
If you live in the US, contact HP Here.
If you are in another part of the world, start Here.
If you are out of warranty, my best advice would be to take it to a local computer repair shop and get a diagnosis of the fault and an estimate for the cost of repair.
Regards,
DP-K

After screen replacement, top half of screen starts by looking normal but then fades to black while bottom half stays bright but with images blury. What might went wrong?

A friend recently gave me their old Macbook pro 15 because they broke the screen and the Apple store quoted them $500-600 to fix it. I looked online and bought a screen of ebay for $170 in hopes of fixing it myself. After getting the screen I hooked it up using the steps I found online. Sadly when I turned it on, the top half of the screen was working apparently normally, but then it faded to black. The bottom half stayed bright with color the whole time but the images were always blurred. When I close the screen with it on, then open it after turning the computer on, the top half lights up with my desktop images as if it is working fine but then fades to black. The bottom is still blurred the whole time. What all could be wrong? Display cable, Inverter cable, not registering the screen or something, the screen is bad? I don't now a ton about all this and I have learned most of what I know from online research. I am not sure if I should send the screen back or if there is another issue. I just want to fix this thing.

Unfortunately, you don't even know the lower half of the computer is working properly, because you didn't have it until after it had been abused. So forget the attached screen for the moment. Connect an external monitor to it, fire it up, and see whether you can get a usable image on the external screen. If you can, send the defective "new" screen back for a refund, or replace the LVDS video cable first to make sure that's not where the problem lies, and if it isn't, then resort to sending the screen back. If you can't get a good image on the external, give the junk machine back to your friend and walk away.

When I press the power button, my screen turns gray with the apply (like it's going to turn on) but then just goes black and turns off completely. What should I do?
