Won't boot unless I hold the power button and shuts off after closing

My mac book pro (current gen) shuts off after closing the screen and won't start up unless I hold the power button for about 10 secs.
Any suggestions?

Do a SMC and PRAM reset and read this guide

My MacBook Pro 13in Mid-2010 won't start unless I hold the power button for about 10 seconds! Help Please!

Hello.
I have a MacBook Pro 13-inch (mid-2010):
Processor: 2.66GHz Intel Core 2 Duo
Memory: 4GB 1067 Mhz DDR3
Running Mac OS X 10.7.2
Yesterday I opened my computer (was sleeping as usual) and the screen just flasehed white and the computer powered off. The magnetic electricity thingy was connected and was green, so it was fully charged, and connected to the electricity.
Since it powered off, I tried turning it on again, and again, one second after starting to boot up, screen flashed white and the computer powered off.
I read somewhere I should hold down the power button longer, so I did, and it booted up. That's why I am able to write this. But every time I turn it off or put it to sleep, it does the same thing when I boot up.
If I don't hold the power button for 10 seconds or so, the computer won't work.
Then today, I did a backup of my entie hard drive, just in case. Later, I started using Excel, and about 1 hour after I was on it, suddenly it got really slow. Like I would click on a program like Safari, and it would take over 30-45 secs to start and be ready. And my computer is usually really fast!
I went on the Internet again, started in safe mode, boot up with option+command+P+R to reset PRAM, and nothing worked. Then suddenly on one turn-off/turn-on (since I can't restart because the computer only starts if I hold the power button for 10 seconds), again it is working at normal speed.
What can this be? Any ideas?
I really appreciate your time and help in advance

Are you running the Apple-supplied RAM? Have you run Apple Hardware Test? I don't know what else you've tried, but this may be time to do a fresh install of Lion if you have not done so since installing Lion.

I was able to download 10.8.5 but have been stuck on the install screen with "two minutes" remaining for an hour now. I'm afraid to hold the power button and shut it off. What can I do to resolve this? :[

What can I do! I know servers are busy but if its installing right now before the restart it means its finished downloading from apple servers so I don't understand why it has been installing with two minutes remaining for a really long time now :[ I'm afraid ill lose all my files if I do a hard turn off.
Thank you guys for your help!

You may have no choice. If you hear no disk activity, you can hold down Command-Control-power button to force a restart. It should pick up where it left off.
No backup is always risky.

My macbook pro won't sleep - if I select sleep it does so initially, then the disc-drive appears to kick in and it comes back to life. It also won't turn off (again, the disc drive kicks in) unless you hold the power-button down for a long period.

☞ 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.
Ifou don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the Console window, select

There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right.

Hey there mello12,
It sounds like you are not able to turn on your phone. You should use these steps in the following article to help resolve it, or setup service if needed:
iOS: Not responding or does not turn on
http://support.apple.com/kb/TS3281
Let it charge for at least twenty minutes, then see if it starts normally.
If there is no image on the screen, press the Sleep/Wake button to attempt to wake the device.
If the screen displays a red battery icon, continue charging the device until the battery is fully charged. Learn more about charging iPhone and iPod touch, or iPad.
If the above steps do not resolve the issue, or the if the screen remains black or shows a persistent Apple logo, try restoring with iTunes:
Connect the device to your computer and open iTunes.
If the device appears in iTunes, select and click Restore on the Summary pane. Learn more aboutrestoring iOS software.
If the device doesn't appear in iTunes, try to force the device into recovery mode, and then restore it.
If the above steps do not resolve the issue, contact Apple.
Thank you for using Apple Support Communities.
Take care,
Sterling

Try the remaining items of:

- 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.

Are the lines like psychedelic herringbone? If yes, I had that happen once, it was something serious, like the
Logic board. The good news is that it was fixed without any loss of data on the hard drive. Take it in to have Apple look at it ASAP. I took it to TekServe at the time, they are very nice about preserving your data and user library when possible.
Good luck and don't panic.

HT201263 my ipod screen turned white and i seen online that you hold the power button and the homescreen button for it to go off. But it wont turn back on. I would have to let it die and charge it it turns on but fades to white. what do i do?

Ipod touch won't turn on, tried holding the 2 buttons and still nothing help!

I need help in getting my ipod touch to turn on. I tried holding the 2 buttons and it wont turn on.

I would put it into a recovery mode to fix it. Try these steps:
1. Unplug the touch from your computer
2. Hold the Sleep/Wake switch until you see the red slider and turn the iPod off. (Note: this may not work and if it doesn't go to the next step.)
3. Start iTunes
4. Hold down the Home button and continue to hold it down while you plug your touch back into your computer.
5. Continue holding it down until iTunes gives you a - "device detected in recovery mode" message.
6. Follow the onscreen instructions to restore your iPod.

Hey, since I have updated to 10.6.3 I have a similar issue. When I put my macbook pro to sleep and I come back a few hours later and turn my external monitor on I notice that the macbook is ON, BUT frozen! The time is usually a few hours back, so the macbook must have started up and frozen shortly after I had put it to sleep. There is no way to restart but to hold down the power button, SUPER annoying!
Hope this will get addressed in an update. Any way your problem is connected to sleep mode?

My mbp won't boot up. It froze so I had to hold the power button to shut down. Now it locks on the loading screen and freezes. Help

Can anyone help? Mbp froze and pressed power button to shutdown. Now can't reboot :(

HTH,

I have a 4th generation iPod and it says iPod is disabled connect to iTunes, but it won't connect to iTunes or my computer. we've tried holding the power button and home button but nothing works. help please!!

I need to know how to rest my iPod when it won't conner to iTunes and says its disabled.

Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Forgot passcode or device disabled
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.

Won't boot unless I hold the power button and shuts off after closing
