today my mac won't turn on at all...the light at the front is remaining on and at a constant brightness however the screen is still black! I'm not sure what to do next?
If you can log in blindly or using the flashlight method, it is possible your screen brightness somehow got set all the way to nothing. I don't have my Macbook with me right now to test it out but I believe it may not be possible to adjust the brightness at the log-in screen so you have to be able to log in first (though I could be wrong on that).

My Mac won't turn back on after I updated the software
My Mac won't turn on
Pull your hard drives.
Put in your OEM DVD
Hold down the letter d on startup and run Apple Hardware Test
Put in your latest OS X DVD and hold c
Does it do both.
Oh, and Reset SMC.

And make sure you have backups, bootable backups, and just WHAT version OS X?? what update(s)?

My mac won't turn on again, it just shows the apple logo and some code
My mac was freezing up a bit while trying to get onto lanaboards.com so I decided to restart it. I figured i might as well update it at the same time. So i did that and chose the restart option that comes up when you update. It seemed like the update went through, but then it told me that it couldn't update but i was asked if i wanted to restart it, so i did. For some reason it didn't restart for a couple of minutes so i turned it off by pressing the on/off button. When i turned it back on it made the sound and then the grey background with the Apple logo appeared. Suddenly this code comes up using the word "panic" a couple of times. I'm not gonna type the whole thing cause it's kina long. It also says "Mac OS version: not yet set" (maybe cause i tried to update?) and "Kernel version: David Kernel version 12.2.1" It also says "debugger called: <panic>"
I won't be able to get it to the apple store for a week because everything closes down on thursday because of Easter and the buses seem to not go tomorrow and no one can drive me. I hope there's something i can do cause i have an important exam (100% of my grade) in two weeks so I'm freaking out a bit here. I also have some stuff due next week that just went up.
I really hope someone can help me, or at least know what may be the problem.
PS. I'm not 100% sure which operating system I have so i chose what i assume is the second newest iOS cause I know i have iOS at least
PS 2: My hard disc crashed about two months ago and was fixed at my local apple supplier, if that may have anything to do with the matter.you are not in MacBook Pro forum, so might be harder to swap out and replace hard drive but you should definitely have had them do that or even yourself.
Make sure you are at least using TimeMachine AND another backup method to clone your system drive so you always have a working 'spare' backup drive you can boot and work from - USB3 is good, TimeMachine even works decently for some on USB 2.0
Finding out why and troubleshooting a panic is a matter of trial and error after taking a look at what hardware, what software you installed (and some of which should be removed), even whether it is triggered by heat from processor or RAM (memory) errors, and memory errors can be triggered by software.

There’s trouble in my laptop paradise. I ended that with this caveat:
It’s much more comfortable to type on the 2011 model, with one big exception: the 2011 model runs much hotter.
I need more time to form a concrete opinion, but it seems so far that this CPU’s awesome performance definitely comes at a cost of increased heat and reduced battery life. For my intended usage as a desktop most of the time, that’s an acceptable tradeoff.
This turned out to be worse than I thought it would be, and today, the last day of my return period, I decided to return it and exchange it for a slower model.
The problem
Not only does the 2011 15” MacBook Pro run much hotter than previous generations, but as a result, the fans very frequently kick up to full speed (6200 RPM), greatly annoying anyone in the area who’s not wearing headphones.
I’ve done a lot of Google research and impromptu Twitter surveys, and this seems like a very common problem, exacerbated by a number of factors:
The quad-core i7 CPUs in the 15” run very hot, with a TDP of 45W, 10W higher than the previous dual-cores. Many people speculate that the 15” case and fan design just isn’t designed for CPUs that need this much cooling regularly.
The Core i7 CPU can use Intel’s Turbo Boost to dramatically overclock one CPU core to handle single-threaded loads whenever power and heat allow. It therefore hits its maximum TDP often when just one core is being maxed out, such as when Spotlight or Backblaze index new files, or when Time Machine is backing up.
The 2.2 and 2.3 GHz 15” models come with an AMD Radeon HD 6750M GPU, which adds significant heat. Modern 15” MacBook Pros dynamically switch between the low-powered Intel integrated GPU and the high-powered (and hot) AMD GPU as needed by applications, but the AMD GPU will always be used when an external monitor is connected — the Intel integrated GPU cannot output video over the Thunderbolt port in the 15”. (Oddly, it can in the 13” MacBook Pro and both MacBook Airs.)
It generates so much heat that it can’t be used in “clamshell mode” (closed, but with an external keyboard, mouse, and monitor attached), which has reduced airflow, without risking overheating, kernel panics, and possible long-term damage. I can’t see why Apple even enabled clamshell mode on it.
Some people report issues with the battery draining while playing a game. The 15” MacBook Pro comes with an 85W power adapter, but when stressing the CPU and GPU (such as when playing a game), the laptop draws about 93W — I don’t know enough about the electronics here to say for sure, but an insufficient power adapter capacity sounds like a plausible reason why the battery might drain under high computational load. If so, this is an embarrassing oversight by Apple.
The thermal paste seems to be very inconsistently applied, or there’s some other common manufacturing defect with the cooling system that varies per laptop. Many, many people reported having these issues and exchanging the laptop for a new one that shows far fewer issues. Many dedicated tinkerers have also reported success after reapplying the thermal compound between the CPU and heatsink, but that requires a very deep, warranty-voiding disassembly that I’m not comfortable doing. (I also haven’t owned thermal paste since 2001.)
Put simply, it sounds like the 2011 15” MacBook Pro has a lot of manufacturing inconsistencies and defects that result in improper cooling. But it also sounds like Apple wedged far too much power draw and heat into an enclosure that’s not designed to properly cool or power these demands. It’s not like Apple to release products like this.
But if I can get one working within my tolerances, it’s still the perfect computer for me right now. So I’m trying.
The attempted solution
Tonight, after requesting the return on my 2.3, I ordered a new, slower model that’s likely to run cooler with less fan noise. It’s the base-model 15”, but with an antiglare (matte) display added:
AMD Radeon HD 6490M: It’s manufactured on the same 40nm process as the 6750M, but has far less computational power, so I’m guessing this will result in much lower power consumption and heat.
2.0 GHz quad-core i7: This is the only CPU available with the 6490M. While I don’t expect it to be dramatically cooler-running than the 2.3 since it’s specced with the same 45W TDP, it does have a lower clock and lower Turbo Boost speeds, so I can probably expect an approximately proportional heat reduction.
So I’ll see what happens. I’m not sure what I’ll do if it doesn’t work out. This generation of 15” MacBook Pros has a lot of problems, and Apple really needs next year’s cooler-running Ivy Bridge processors as soon as possible.

My computer won't turn on. When you hit the power button you can hear the fans turn on but thats about it. This has happened in the past, it's not turned on for about 3 days but then all of sudden it starts working again. Its been about 5 days now and I'm starting to get worried. I hear the fans running but thats it, I can't eject the CD tray and I can't see any video. What should I do??
iMac g4 Mac OS X (10.4.5)CDiddyHustle,
Welcome to Apple Discussions, Sorry about the circumstances!
To help identify what's at fault could you please post back with the following details:
Do you get the Start-Up chime?
Does the Optical Mouse light up/Caps Lock light come on or off?
If you shine a torch at the display and look closely can you see any images?
If you have a VGA display adaptor - can you see any display if you plug it in to your TV or similar.
If you reset the PRAM - hold down the <apple>
<r><alt>keys in during start-up until you hear the computer appear to restart.
If you hold down the mouse button during start-up does the CD tray open?
Was the computer showing any other symptoms recently - dimming display, Kernel panics, poor USB connections, grinding noises in the hard disk?
Do you have a clean electrical supply in your part of the world?

You said "reset," so Meg assumed that's what you did. But "reset" is not a button; to reset the phone you must hold the HOME and SLEEP buttons at the same time until an Apple logo appears. You may have to hold for up to 30 seconds, and if the battery was completely drained, you will have to restore iOS using iTunes on your computer.

My mac won't turn on and I want to try and back up my files in case it needs to be reformatted. Is this possible if it won't turn on?
See this Apple note on systems that won't power up. If the system won't power on, the only way to backup your files is to remove the hard drive from the system, and either put it into a case or attach a cable so another system can read it.

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 -
My question won't all fit in but it says 'My iPod Touch 4th Generation 8gb won't turn on and is frozen on the loading symbol/wheel. What do I do?'
I've had this problem from about two weeks and I forgot about it, but today I wanted to play on it and remembered that it's not working, I've tried connecting it to iTunes via my laptop but I'm not to sure how to update it because I thought that might fix it, but no luck. I've tried the trick where you hold the lock and home button but nothing happened apart from it just went back to the apple logo and then to the frozen loading symbol/wheel. I need help!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.
- 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.

My Ipad2 won't turn off. I have tried the reset method by holding both buttons down for at least 10 seconds, but this doesn't work. I can't get onto the internet via wi-fi either (don't have a 3G card fitted). All other functions seem to be working OK including charging. Not had this problem before, but I recently upgraded software to 5.1.1 so is there a bug in there somewhere?
Look at last link.

iPad: Issues connecting to Wi-Fi networks http://support.apple.com/kb/ts3304
iOS: Recommended settings for Wi-Fi routers and access points http://support.apple.com/kb/HT4199
Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.
