TS4080 apple thunderbolt display image on display intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys. Rebooting by pressing the power button resolves issue.

My apple thunderbolt display (which I purchased 1.5 years ago; OS 10.7.5 Mac Mini) intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys, so am thinking it is a hardware problem with the display. Rebooting by pressing the power button turns the screen back on, but the same phenomenon has occurred several times. Could this be a software issue, or do I need to have my display repaired? Your feedback would be appreciated.

Hi ED, tough to tell, but it does sound like it's waking with the bonk, just not displaying.
Long shot but...
I wonder if it's a variation of this, of which I've seen many different symptoms...
Resolution
Move the mouse or trackpad cursor over the center area of the login window so you can see the user icons. Click on the icon of the user that you would like to login as, type in the user's password, and press Return.
If the login window is configured to show only the name and password fields, type in the user's name and password into the fields, and press Return (even if you cannot see the rest of the login window).
Additional Information
This issue will not occur if the display is not sleeping when the account is logged out. Use the steps below to confirm that the account is not configured to log out automatically while the display is sleeping:
1. Open System Preferences > Security & Privacy > General. Click the padlock to unlock the preference pane and enter your admin password. Click the Advanced button at the bottom, then see if the option "Log out after N minutes of inactivity" (where N is the number of minutes) is enabled.
2. Open System Preferences > Energy Saver and configure Display Sleep to occur after the account is logged out, by dragging the slider to a number of minutes that is greater than N was set to in the previous step.
Important: If automatic log out is not needed, disable "Log out after Nminutes of inactivity" in System Preferences > Security & Privacy > General. This will also prevent the issue.

MacBook Pro display sometimes does not wake from sleep, display is blank

My computer has been getting a lot of this weird issue that it is asleep, the light is pulsing. But when you go to wake it up, the keyboard lights up, caps light key will work, but the display is blank, nothing makes it turn back on.
I had a friend using it who I let use the guest account, but since the issue kept happening and all the guest account data kept disappearing, I had to create her an account. It's annoying, and sometimes if I catch the crash happening while the unit is display active, I get the color wheel and all the apps freeze up really bad. I'm lucky if I can save my work.
Sleep during this crash will also produce the error. Most recently I was trying to connect my bluetooth keyboard and it kept giving me an error. So I tried to turn off the bluetooth, no dice. Went into the root user, still no dice. Figured maybe the device didn't get reinitialized upon wake from sleep properly, put the unit to sleep and ding dong, wont wake up again!
From the console logs I've been able to find this string:
5/23/10 1:00:54 PM kernel Sleep failure code 0x00000000 0x21000000
I've not used any hacks or sleep widgets, so I don't know what the issue is.
Everytime I reboot from this I fsck the drive and repair permissions. I've tried zapping the PRAM also, next stop is delete the power management plist and reset the SMC. Who knows if any of it will work?
Anyone have any ideas?

AppleCare is the magic word. Time to contact them.
Btw the machine is 10.6.3 I hadn't updated my settings before I posted the initial question.
I was actually going to suggest that, but noticed in your later posts you had updated the info.
As for the smc and pram both were done today, so we will see what the story is. I also deleted the energy .plist file and had it recreated from within root.
Just curious why you're working in root? You should be able to do anything we've discussed from an admin account, and there's lots of potential for mishaps in root.
As for dlrunning DU, I was under the impression that it just ran fsck through the DU GUI. At least that's what it looks like when you view the console log for DU. I'll give it a try though.
I'm just repeating what Apple suggests.
I'm just worried that the little glitches are adding up to something catastrophic.
AppleCare.

I have an iBook g4 14" 1.42 ghz. I recently installed a new hard drive. I put the install CD in. Then, I pressed the power button, then the "C" key. Black screen and No chiming. Please tell me, what I can do to resolve this? What is the problem with it?

Since it will not boot then a hardware test can't be run. You could try FireWire Target Disk Mode and if it works then access from another Mac to run tests on the new drive. You could also try installing the OS X software from the host computer. If this does not work then professional help should be considered.

So just like last time I tried to update my iPhone software...MY PHONE IS FROZEN. Displaying iTunes icon and a USB cable I pressed the Power button and the menu botton together until the apple icon appeared held them down for 10 secs & NOTHING Now what? Do I just wait for the battery to run out?

Hi Careesa,
Your iPhone is in recovery mode-- you need to connect it to your computer and, most likely, iTunes will ask you to restore it. If you recently backed up this shouldn't be too much of a problem.

My A859 displays "Have been in meta mode, long press the power button and the normal boot"

Hi,
I charged my phone until 100%. Within 4 hours, the battery showed 1% and shut down automatically. Then, when I tried to switch on it displays "Have been in meta mode, long press the power button and the normal boot". I thought that the battery is running out, so i charged half an hour. When I tried to switch on, the screen is blinking with light but no display. Now i cannot switch on my A859.
Anyone can help me on this? i just bought this phone few days before :'(
Solved!

Hi
Have you updated the phone in this time?Did you root it?
You should reinstall the OS.HERE you have the official ROW(Rest of the World) international firmware(You can OTA update to the latest version,if any, after)
HERE you have the installation instructions.
Pay special attention to the SP drivers>See message 7 of http://forums.lenovo.com/t5/Lenovo-Phones/Lenove-S650-sound-issue/m-p/1413747#M3660 ( the topic refers to a different model but the installation process is the same for all Lenovo powered phones).
Let me know how it goes.

I used to install the rEFIt to boot with win7. When I deleted win7, I didn't uninstall rEFIt. Nothing wrong with it. One day after I watched movie in full screen,I pressed esc to quit. Then I found the touchpad didn't work. I can't turn off air. I just pressed power button for a little while. It rebooted, then my nightmare just began...
I have tried everything, PRAM, command+R, literally everything. No change.
But when I plug a CD-ROM with USB, I can only here one BONG, just once, then white screen, Like waiting for something...
I took it to a service center in China, they told me the CPU had broken. SInce it's one month out of warranty, they wanted to charge me for like $250....
I really don't think that's CPU's problem. I checked the history, it seems like somebody else also had the problem before.
Can anyone give me some hints??? Thanks!!!!!! Or I have to take it back to America to check....

Impossible, there are zero, as in none, zip, nadda viruses for OS X. If you have viruses on it they are for MS Windows and will not affect OS X. I suspect the hard disk has crashed, if you have backup then it's not a big deal to have it changed, just take it into your local Apple Store or AASP for service. If you have not been backing it up you may be in for a painful lesson on why backup is critical.

See Ogelthorpe's link:
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac 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.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

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!

Because of low battery my iphone 5 got switched off and than its not starting by pressing the power button or by keeping it on charge. While charging a white screen comes for 2 second and goes away. This process continues till the phone is on charge. Please suggest how can I start my phone.

Hello Ritugor,
I would be concerned too if my iPhone was not powering on. I found an article with steps you can take when you encounter an issue like this. I recommend following the steps below:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

Sorry, possibly you need a new hard drive or try reformating. First
you can try something like http://www.alsoft.com/diskwarrior/ it has been known to repair disk that DiskUtility could not. YMMV and they don't give it away.
If Disk Warrior can not repair then you need to Reformate the drive. Make sure you have a back-up in place no matter what.

Disk Utility will tell you something about it's SMART status:

Safari will lock up on my MacBook Pro. Force quit doesn't help. When I try to restart the computer, I get an error saying Safari cancelled the restart. I have to press the power button to shut down the computer.

While I'm using safari, it will freeze up. When I force quit safari and reopen it, I find that I'm back to where I was when I did the force quit and safari remains locked up. When I try to restart the computer, I get a pop up that says that safari cancelled my restart. I then press the power button to shut down the computer. When I reboot the computer and open safari, I see all the tabs and windows that were opened when this issue began, only this time safari isn't frozen. This problem started yesterday.
Has anyone experienced the same problem? Is there a fix for this problem?

Try Resetting Safari: Open Safari. Cick on the name Safari in the menu bar. In the drop down menu click Reset Safari.

P35 Platinum: I have to press the power button multiple times to start

Hello fellow MSI customers,
as written in the subject, I have a problem with starting my PC. When I press the power button, the computer powers on, but there is no output to the screen. In fact, my LCD stays in standby mode. I can hear the fans running, so something is going on. According to the LEDs on the mainboard, it is a memory problem.
Now I turn the computer off, using the power button (have to hold it for a few seconds). When off, I start again and everything runs as it should.
After starting, I ran memtest86 multiple times without any errors. I ran a few games, compiled some programs, installed Vista 64bit, Linux, all without any crashes or hangups. It is just the starting that makes problems. After booting it is very stable.
Seeing that it could be a memory problem, I brought another pair of memory, just to be sure. I couldn't reproduce the problem on that day! Any type of memory I put in (the one before, or the newly brought home) the computer always started on the press of the button. So I thought, OK, maybe they were not seated correctly. But, alas, two days later it is again only starting by pressing the power button three times.
What I tried:
1. Boot using only 1 piece of memory stick
2. Boot using only 1 piece of memory, but different one
3. Use another pair of memory <- worked, but on that day it also worked using my original memory
4. Disconnected everything except graphics card, to make sure it is not a power supply issue (minimized power usage)
5. Tried all of the above with a different processor
6. Used another power supply
Any other ideas?
Here are my specs:
MSI P35 platinum
Core2 Q6600
Nvidia 7900GT
4GB V-Data DDR2 800MHz <--- I think this is the problem, any experiences?
Enermax Liberty 400W
a few other things (HDDs, XFi, DVD-RW)
By the way, how can I boot from an external DVD-RW? It doesn't show in the menu when I press F11 (boot menu).
Thank you for any help, muro
And just to let a bit of steam off:
1. I had major problems with the RAID controller (not MSI fault, rather intel) - I put two disks into a RAID 0, then RAID 1 and they always failed after a few boots - member missing on both disks. I was getting angry, so I put them as normal (non RAID) disks and everything is fine since, although no RAID.
2. Installing anything except windows with an IDE DVD-RW is very hard. It took me ages until I got Ubuntu booting (there are guides on the net, google is your friend), and much longer to get grub (boot loader) working. Long story short - if you have multiple disks, use the Linux disk as the bootable, do NOT put grub on the disk where Vista is installed.
3. I have no idea, how to update the BIOS, if I had to. I'm using 1.1 that came on the board. I use 64bit Vista and Linux, none of which is supported to upgrade the BIOS. Any hints how to do it (if I needed to)?

Hello,
now today is the day I've finally received my replacement board. The good news first - it DOES work! Yepeeee!
Now some more information:
The jmicron controller seems to be missing - a screen with something about "Marvel" is shown before the intel raid screen. However, it is only visible for a fraction of second, so I cannot read it. I think it detects my IDE DVD-RW so I'm quite certain it's the replacement for jmicron. I won't miss it - it took me ages to install Linux with the jmicron controller.
The problem where I had to restart the computer sometimes because it didn't even post (RAM error) is gone. It boots just fine now.
I had an extremely long first post - about a minute, but after that it boots very fast now.
anyway, regarding some questions around here - the manual states MSI recommends using an 350W power supply. My 400W is more than enough. Please note - it is an Enermax, not one bundled with a cheap case. My cheap RAM sticks also work very well now. I did try them on different boards before, so now I know I just had a faulty board.
In the end, I can only say this: This is my 3rd board already and it's the first one that works well. As the hardware changed, I presume there were major issues with this board that lead them to make a new revision. What is strange, though, is that the revision is still 1.1, as were my previous two. I pity everybody who had the same problems as I did, but I can now say that I'm very happy about the board now.
Cheers, muro

Hey terremo,
Thanks for the question. From the information you provided, it sounds like the iMac is successfully turning on, however video is not displayed. These symptoms can usually be isolated further by the troubleshooting steps in this article:

Always need Disconnect power, press the power button wait for 10 seconds...

I bought a HP computer for a couple of years ( Pavilion a6695it ) It always works well. But in recent days, I can not start up it. I tried pressed power button on the front of the computer, nothing happend. Then I searched in hp site. finnally, I find this article http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00241069&tmp_task=solveCategory&cc=it&dlc=it&lc...
In english version the article is here:

Power supply light is on or flashes
Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure:
CAUTION:This product contains components that are easily damaged by ElectroStatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC.
Disconnect everything from the computer, including the power cord.
With the power cord disconnected , press the power button on the front of the computer and wait for ten seconds.
This is work for me. But now, my computer always need this methond that it can be started up.
Disconnect power -> press the power button and wait for ten seconds -> then the system will start up
So my question: where is the problem? Which part is broken and i should replace? Thanks.

Youli
