HT201177 cant turn on my imac just a black screen which i never shut down to begin with
help i walked in to find my imac with a black screen and i cant turn it back on has this happened to anyone else? how do i get it back on
You're sure the electrical socket it's attached to has power? That socket isn't controlled by a wall switch, which is off? If the socket is good, see this Apple note for systems that won't turn on.

I was surfing online when suddenly my mac just freeze. So i had forced shut down it and turned it on again but then the folder with questionmark icon shows up. And i pressed (option key) to go to the utility but i cant find my startup disk anywhere!
Well, if the internal hard drive is no longer readable, there's pretty much nothing anyone here can do about it. There are no magic words that will fix a hardware problem.
Make an appointment at the genius bar and have it looked at. -

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- 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.

My phone died last night and when I plugged it in it wouldn't turn on.I tried restarting it but it has yet to turn on since last night,It was just a black screen,i try the on/off and home buttons together but its not working,What should I do?
How long have you had your phone? Because if you've had it a long time, the battery in the phone might of died on you. Or have you dropped it in water, snow, from high up? All those things could of disconnected something internally in your phone, or permentaly damaged the internal hard drive its self, or the sims card.

Hello, I can't turn my iphone 4s on, it just broke down and now there's just the black screen with the apple logo on it. So I connected it to itunes and tried to restore it, but than always the errors 1603 & 1611 appeared! please help me!!
You may have a faulty USB cable. Try another.
Make sure you are following the instructions in this procedure to the letter. Here they are, with emphasis on some easily overlooked requirements:
Disconnect the USB cable from the iPhone, but leave the other end of the cable connected to your computer's USB port.
Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.If you cannot turn off the device using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the device turns off, release only the Sleep/Wake button.
Continue pressing and holding the Home button while you reconnect the USB cable to the device. The device should turn on.Note: If you see the "low battery" screen, let the device charge for at least ten minutes to ensure that the battery has some charge, and then start with step 2 again.
Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears (iTunes icon and USB connector) release the Home button.
If necessary, open iTunes. You should see the "recovery mode" alert ("iTunes has detected a phone in recovery mode").
Use iTunes to restore the iPhone.
If you do not see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
Select the device in iTunes and choose "restore from backup".
If you still can't get it to work, you have done all you can and only Apple will be able to help. -

hi, i woke up nd my device will not turn on . ive tried the home and unlock button, my phones on a charger also but the battery wont pop up. just a black screen. What do i do ?
Leave it alone for an hour and try the reset procedure again. Make sure you're using a genuine Apple charger & cable in a known good wall outlet. You can also try another cable if necessary, and make sure the charging area is clean and free of fluff & debris.

just got a replacement iPhone 4s and i let the battery run down all the way before charging it and now that i have put it on the charger it won't turn back on or show any signs that it is charging. its just a black screen. how do i fix it
Keep iPhone on wall charger for ten minutes, it may turn ON itself. If still nothing, keep on charger and Reset, hold both home and power buttons for about 20 seconds until the iPhone begins to respond.

My iMac never shuts down properly
My iMac never shuts down properly, sometimes it says that i need to force quit my wireless internet but even when i do that it just has the white screen and I have to hold the power button down to turn it off properly, why is this and how can i stop it
Hello,
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed. Or an errant process eating up RAM.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

I have the Iphone 5, it is just over 12 months old, and it was low on charge, by the time I could get to a charger it had cut out. So i plugged it in the charger like no other time, went back after 10mins and noticed the screen was still black. So i tried to turn it on but nothing still black screen, i changed the charger for my other apple charger and the same thing happened. i decided to plug it in using the usb in the computer and still the same thing has happened. Took it to the apple genuis team to be told they can`t do anything, and now its out of its 12 months warranty makes it even more difficult. Has anyone else had this issue, this is my 4th iphone since they released them and am very dissappointed to say the least that the iphone 5 for me seems to have a life span on just over 12 months and no one is prepared to take any responsiblity as i have not damaged it. One extremely dissappointed Iphone user. Any ideas on how to get it working again?

is it okay if we never shut down and just make the computer to sleep or we just put the flap(screen) to save the energy?
I recommend users to put their computers into sleep mode to save energy, and also, they won't waste time turning on their computers. You should only turn off your computer if you aren't going to use it for a very long time, but sleep mode is perfect. If you just turn off the display, your computer will still be working, so you mustn't do this unless you are going to use your computer in a short time

my imac (intel core i5, OS 10.10.1) shuts down every night and will not "wake up" next morning -- it never used to do that -- if I hold down the start button more than twice for many seconds, then it will finally boot up and works fine all day – I’ve tried shutting it down and unplugging it, and that does not work -- I’ve run disk utilities checked permissions, and run anti-virus and get no adverse results – I cannot figure out what is different that causes this problem
From previous experience 3 indicates a shutdown initiated by the SMC (System Management Controller) — hardware responsible for many low-level functions including power, sleep, lights, and fan activity.
Try resetting it:
Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer. -

Did you ever figure out how to turn your phone on? Mine died today around noon for no reason. I'm so mad at it! I can't get it turned on, and I KNOW the battery is charged. Suggestions? I'm going to the genius bar (another trip completely out of my way) tomorrow morning. Suggestions?? Oh and please don't tell me to hold the "home" button and the "power" button together because I've been doing that all day. It doesn't work.
