Troubleshooting: My computer won't turn on
Memory or hard drive space?
When you can get the Mac to boot, click About This Mac from the Apple () menu then click More Info then select Storage.
Make sure there's at least 15% available disk space.
And Troubleshooting the MagSafe adapter

My mac wont turn on. It is charging and the on light is on when the computer is shut but once I open it the light turns off and the screen is black. I turn it off and then on again and the start up noise goes but it is still black - Help!?

Claire, please post your machine specs as requested. There are some variants of the MBP with specific hardware issues. Example: the older "silver key" MBPs with 2.2Ghz and faster processors can have a defective video chipset that produces a black screen or distorted video. That problem is covered under an Apple program that will fix this at no cost to you if you computer is that model.
Do "About this Mac" from your Apple menu and, in the resulting window, click the "More Info..." button. That launches System Profiler for you. The first screen looks like this:
The second line, "Model Identifier" (or "Machine Model" if you are running OS10.4) precisely identifies your MBP variant. Post that, and include it in your equipment info in your profile for future posts. That means people don't have to ask, and you get faster help that is targeted to your specific model. Saves everybody a bunch of keystrokes and you get better advice.

BB 8120 WONT TURN ON - HELP

Had it since october 09, was listening to music then all of a sudden it turned off wont turn back on, I recently had it unlocked but its been working fine until now, Please help me

Start by doing a battery pull. Simply remove the battery for 15-30 seconds, then reinsert it and wait for the device to reboot. That may help, but it may not. If it doesn't, then the next step is to ensure that the battery simply isn't dead. In that case, plug it into the BlackBerry wall charger for a couple of hours and then see if that helps. Note that in this case, if the battery is dead, charging via the USB cable, a car adapter or a non-OEM charger may not work, so it would be best to use the actual wall charger.
If none of those help, then let us know and we can try to take things a little further.

My ipod touch 5th generation wont charge or turn on at all,
i upgraded to iOS 6.1.3 and after that my ipod started having trouble charging, at first i though the lightning cable was the problem so i bought 2 more lightning cable chargers and my ipod still would'nt charge, so it died. now the only thing my ipod does is when i try to turn it on it shows the apple logo and then the screen goes off and does it again for a few times and then the screen stays off and my ipod gets really hot but wont turn on for the rest of the day help!!

The hotness indicate a hardware problem.
Make an appointment at the Genius Bar of an Apple store.
Apple Retail Store - Genius Bar
or send it to Apple.
Apple - Support - iPod - Service FAQ
If not abused Apple will exchange it for a refurbished one at no coast. otherwise the exchange price is $149.

Playbook wouldn't charge, and now wont turn on, HELP?

So yesterday, I tried to charge my playbook, but it wouldn't work. Its not brand new, but its not old either, I have had it for a month maybe? I used the charger that came with it, and I tried using the USB too. Neither worked. I tried my charger on my friends playbook (same kind, we bought them together), and it worked, so I know its not that. I tried leaving it over night, still nothing. Now it wont turn on either, the little button thingy (pardon my non-technical terms) at the top just turns red, then flashes yellow/green five times. Any suggestions are welcomed, please and thank you!

Try a hard reset with it plugged in...press and hold the power and volume +&- until the device restarts...worked for me.

PLEASE HELP! MAC WONT TURN ON!!!!

My fellow mac users, I am hoping that ya'lls wisdom can solve this problem I just encountered a few days ago. I have a White Macbook 13inch and have had it since 2008. I just recently upgraded everything. New 320gb hard drive, 2gb RAM, Snow Leopard, and iLife 2011. I have been using it all for a month now and everything is running beautifully.
Last week, I turned my computer off, as usual for the night and when I woke, the computer would not turn on with the power button. I opened up the computer and dusted it and still nothing. I ordered a replacement keyboard from ebay and plugged it in and low-and-behold, It turned on. I wanted to make sure that the original keyboard was broken so I plugged that one in and it worked as well. Including the power button.
Now I just tried to plug the new one in and it doesn't work at all. But the original does. I am worried if I turn off the computer again, I won't be able to get the mac back on. If anyone has ANY suggestions, they would be most appreciated. I don't want to take it to Apple because I know they will charge me $400 for this computer and I clearly don't have that. Any advice would be most gracious!
Thank You!

Did your replacement regimen include a new battery? Have you ever calibrated the battery? : http://docs.info.apple.com/article.html?path=Mac/10.6/en/9036.html
Reset the SMC? : http://support.apple.com/kb/HT3964?viewlocale=en_US
Does it start normally when the battery is removed entirely?
Does the Magsafe adapter still show a green light when connected and fully charged?
To check the number of cycles and 'health' of your battery, click on Apple in the menu bar, About This Mac, More Info, and Power. 'Average' lifespan of the standard battery is considered to be about 300 cycles, and a removable MacBook battery typically registers at least 4800-5000 mAh fully charged when brand new.
Last possibility that comes to mind is that you're wearing out the power switch if you indeed turn it off every night. In my experience, OS X is stable enough that I often leave mine run for weeks without a restart. I just close the lid when I'm not using it.

Help!!! my mac wont turn on......

I have an imac that's like 5 years old and just recently it started running slower and slower and then one day it froze up so I tried to reboot it and now it won't turn on :( i turn it on and it goes to the grey screen with the apple but stays on it unusually long, like 10 mins. Then it switches to a blue screen where it stays on for like a min, which after that it just goes blank. It appears my mac is still on but there's no display or anything. Is there anything I can do?

How much free disk space is on that boot drive? You should leave about 20GB to 25GB free for the OS.
As a first step boot from your installer dvd and run Disk Utility from there to repair/verify your boot drive (not repair permissions).

Help! my mac wont turn on or charge. the charger light is a dim green (ive used several different chargers) what should I do?

My mac was working and charging fine yesterday. I woke up this morning and it would not turn on or charge. When I plug in any charger the charge light is a faint dim green. I dont know what to do.

Keep it plugged in for couple of hours.
You may have to take the computer to the Apple store to have it checked.
Best.
