Why is the power button (which I need daily) missing on Apple TV?

As there is usually no other way to get Netflix to show up when it says itcan't be reached.
Very annoying and presumptious.

Press and hold the centre button on the remote and the light will give a quick flicker.
Let go of the button and it will be switched off.

Why does the power button intermittently fault -- Not work to wake up the phone?

Iphone 4 occassionally won't respond to the power/sleep button. Isn't stuck -- works normally much of the time, but occassionally acts as though the battery is dead. Have to plug into a power source to activate phone. Battery will show same charge it had before it went into sleep mode. Can be near fully charged and proceed working for the rest of the day just fine.
Button does not stick or seem faulty in any way. But, when you least need it to not work - such as in travel - or for emergences and have not power source to get to -- is bad. An unreliable phone for a doctor is not good. I have presented the problem to a few repair shops who are either not familiar with this behavior or suggest that is may be software rather than hardware. Something miss reading the battery to the phone indicating that the battery is dead when in fact it is not. Had the phone restored at the Apple store and this did not solve the problem.
It seems I did run across a blog that this occurred with some IOS update?
Would be grateful for advice.
Thanks

Hi
I found this tip on the net.
Plug phone cable in (powered), press and hold button until voice control is activated, release, unplug.

There are a simular trick to get the home button to work, here it is.
Open a default iOS application, such as Stocks, Calculator, or Weather
Press and hold down the Power button until the “Slide to Power Off” dialog appears, then release
Now press and hold the Home button until the “Slide to Power Off” screen disappears, quitting the application.

My ipod touch will not turn on when plugged in or when I press the power button. I need to send it in for reapir, but I need the serial number. Any round about solutions?

The back of the Ipod is warn so I can't see the serial number, so please let me know if you know anything that would help.

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

Can i turn my notebook on without pressing the power button?

I have several MacBooks (no! not MacBook Pros) and I wish to build a stamnd for them on my desk so that they all stack up, and can be controlled though a KVM.
I have all the hardware and infrastructure designed, but I can't seem to find any way of turning them on except by opening the cover, and pressing the power button.
I can't really imagine Apple designing the perfect tool with this sort of problem?

Restore the device.
If the problem continues, restore as new.

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!

"You need to restart your computer. Hold down the power button for seve..."

Hello,
I have recently been getting this same message "You need to restart your computer. Hold down the power button for several seconds or press the Restart button." whenever I start up my computer. It happens about 95% of the time. I have been reading on different forums that I should reset the PRam and the NVRam and I have been doing so and it does help as it does EVENTUALLY start up (sometimes takes me 5-10 min. to get it to start up).
I have also read that it may be the RAM that is loose, so I did check that and made sure that the ram is properly placed (which it is).
I don't know what else I can do. Should I reformat and reinstall Mac OS X?
Here is the exact error form the dump:
IOAPIC: Version 0x20 Vectors 64:87
AppleACPIPlatformExpert::start failed
panic(cpu 0 caller 0x55c095): "Unable to find driver for this platform: \"Macbook 2,1\".\n"@/SourceCache/xnu/xnu-1504.9.26/iokit/Kernel/IOPlatformExpert.cpp:1389
Debugger called: <panic>

Well just got around to installing the new HDD and RAM yesterday, and I am sad to say... that the problem persists. :/
I reseated the memory and made sure they were in there properly, and I also installed the HDD and ran DiskUtility before I erased/reformatted and installed a fresh version of MacOSX Leopard, then updated to Snow Leopard.
As long as I am using my computer everything works fine, the problem occurs when the machine is shut off or put to sleep for a long period of time. Because when I shut it off and turn it right back on a few minutes later it works, or if I shut the lid and open it 10-20 min. later everything works fine, it's only when the machine is off or asleep for long periods of time.
So, I do not know what else can be wrong.
Should I try to take out the old RAM and just leave the new module in and see if that works out? See if that specific module is faulty?

My mac mini will not shut down. I need to manually shut it off with the power button.

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select

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

I need to hard reset a Palm TX but the Power button does not function.

I need to hard reset my Palm TX but the Power button does not function. Is there any other way to perform the hard reset or otherwise delete all of my data?
Post relates to: Palm TX

Hi,
PowerBtn from the Canuck Software HomePage.
NOTE: This is Not a Blazer friendly download and only for downloading using a Chunky Computer thingie.
http://www.canuck-software.ca/
PowerBtn will allow you to set a HardButton to turn the TX on and off in the same fashion as the PowerButton, if you want.
This setting will remain active while 'Enable' on the PowerBtn screen is active.
The user can select 'Disable' on the PowerBtn screen.
The setting will survive a Soft Reset. (Hi PG )
If the Palm PowerButton fails completely then you will not be able to do a Hard Reset.
The PowerBtn app has a 'Hard Reset button' which you tap and after a time countdown (you can cancel in this time) it will perform a Hard Reset. This is the same as the Hard Reset app mentioned above.
The 'Enable' and 'Disable' mentioned above do not affect the 'Hard Reset button'
NOTE: PowerBtn also has a 'Program itself becomes power button' feature but I do NOT recommend you use this.
If you enable this you will not be able to change the setting or use the 'Hard Reset button' because when you Tap on the PowerBtn Icon the TX will turn Off. The only way to change the setting or use the 'Hard Reset button' would be to Delete PowerBtn then install again.
You can also turn your TX On by pushing the 5WayNav Select (middle button) to bring up the clock then double push it. The TX will stay on at the same place it was in when you turned it off, in the same way it would if you used the Power Button
All the best, woz of oz

Why is the decline button for phone calls not available when the phone is locked? I need that button and it shows only when the phone is not locked on iOS 7

Why is the decline button for phone calls not available when the phone is locked? I need that button and it shows only when the phone is not locked on iOS 7

Yep. You need to touch the sleep/power button once to silence the ring, and twice in order for the call to go directly to Voicemail.
Personally, I dont understand why Apple eliminated this. If you wish to give Apple feedback, do it here:

If your iPod Touch, iPhone, or iPad is Broken
Apple does not fix iDevices. Instead, they exchange yours for a refurbished or new replacement depending upon the age of your device and refurbished inventories. On rare occasions when there are no longer refurbished units for your older model, they may replace it with the next newer model.
ATTN: Beginning July 2013 Apple Stores are now equipped to do screen repairs/replacements in-house on iPhone 5 and 5C. In some cases while you wait. According to Apple this is the beginning of equipping Apple Stores with the resources needed to do most repairs for iPhones, iPads, and iPod Touches that would not require major replacements. Later in the year the services may be extended as Apple Stores become equipped and staffed with the proper repair expertise. So, if you need a screen repaired or a broken screen replaced or have your stuck Home button fixed, call your local Apple Store to see if they are now doing these in-house.
You may take your device to an Apple retailer for help or you may call Customer Service and arrange to send your device to Apple:
Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.
To contact product and tech support: Contacting Apple for support and service - this includes international calling numbers.
You will find respective repair costs in the appropriate link:
iPod Service Support and Costs
iPhone Service Support and Costs
iPad Service Support and Costs
There are third-party firms that do repairs on iDevices, and there are places where you can order parts to DIY if you feel up to the task:
1. iResq or Google for others.
2. Buy and replace screen yourself: iFixit
Locked Out, Forgot Lock or Restrictions Passcode, or Need to Restore Your Device: Several Alternative Solutions

1. iOS- Forgotten passcode or device disabled after entering wrong passcode
2. iPhone, iPad, iPod touch: Wrong passcode results in red disabled screen
3. Restoring iPod touch after forgotten passcode
4. What to Do If You've Forgotten Your iPhone's Passcode
5. iOS- Understanding passcodes
6. iTunes 10 for Mac- Update and restore software on iPod, iPhone, or iPad
7. iOS - Unable to update or restore
Forgotten Restrictions Passcode Help
iPad,iPod,iPod Touch Recovery Mode
You will need to restore your device as New to remove a Restrictions passcode. Go through the normal process to restore your device, but when you see the options to restore as New or from a backup, be sure to choose New.
You can restore from a backup if you have one from BEFORE you set the restrictions passcode.
Also, see iTunes- Restoring iOS software.

After installing Mavericks my MacBook Pro and my MacMini can't shut down, only a grey screen and finish. Must be killed by the power button. Why?

After installing Mavericks my MacBook Pro and my MacMini can't shut down, only a grey screen and finish. Must be killed by the power button. Why?
Nach der Installation von Mavericks kann ich weder das MacBook Pro (2 x 2.4 GHz) noch den MacMini (2 x 2.66 GHz) herunterfahren. Es bleibt ein dauerhafter grauer Bildschirm. Nach 20 min habe ich einen erzwungenen Neustart durchgeführt.
Ausserdem startet die Macs wesentlich langsamer als mit OS X 10.6.8.

same here... sometimes it works, most of the time it doesn't!!

Why is the power button (which I need daily) missing on Apple TV?
