Hi, macbook occasionally takes a very long time to turn on with the power button.. this makes me very nervous.. can anyone allay my fears?
Make sure your boot volume ("Macintosh HD," unless you gave it a different name) is selected in the Startup Disk preference pane.

New macbook pro fail to respond to the power button
Why did my new macbook pro fail to respond to the power button?
I have a new 13" MacBook Pro Retina (10.9.1) which I have been using for about 3 weeks. I am new to Mac and am in the process of making the transition from Windows XP.
Today, with the battery at 100% and the power lead disconnected, I left the mac with the lid closed but, when I returned, it did not come back to like when I opened the lid. Also, it would not respond to the power button.
After some web searching, I managed to get it back to life after resetting the SMC.
Is this a software problem, or is it more likely to be a hardware problem?Highly unlikely that software is involved - especially since resetting the SMC corrected the problem.
Unless it happens again, I would forget it. If it occurs again, take it in for warranty service.

my ipad is locked up since downloading icloud. icannot turn it off with power button.
That makes sense after re-reading the original question. I thought the OP was setting up for the first time. I must be getting old... I have misinterpreted a few questions over the past few days....Or my brain is on hiatus!

2009 Macbook Pro's fan spin faster with power adapter plugged in?
I was playing restaurant city on facebook with macbook pro with the power adapter plugged in
( a flash game)
after a while, the fan starts to spin faster and faster and made noise, and the body of the laptop starts getting hot too.
However, when I play the game without the power adapter, the laptop stays more quiet, and the i can't hear the fan spin anymore...(which sounds good)
but what i am worrying is that, is the hardware SUPPOSED to get hot and the fan is supposed to spin faster? the reason why it is not is because the computer recognize the power adapter is not plugged in, so it forced the fan to stay at a lower rpm to conserve power? (which do harm to my hardware?)Hi
that sounds normal to me - charging the battery produces heat, which must be removed via the fans.
They didn't run slower to conserve power, but because they weren't needed to remove the heat by=product of charging.
Flash is a real cpu burden. -
MacBook Pro won't turn on. Power drained?
A icon popped up saying that the USB was taking too much power and it will be disabled but before I had the opportunity to unplug my iPhone which was charging thought my MacBook Pro, the whole laptop shut off. It won't turn back on and even as I put the charger in, the green light doesn't appear!! Please help
There's a small voltage board by the Magsafe connector inside the machine. It's either that or the mother board. How can you be sure the supply is good?
In any event, if you have Applecare they'll fix it for you for free. If not, the Genius Bar eval if free, though the repairs will cost. -
After resetting the SMC the keyboard is inoperative. On the start screen appears a traslucent square with a horizontal bar in white, and a row of empty dots below (the same format as for example the brightness symbol). I cannot turn the Mac off with the power button, only with the trackpad, clicking on the turn off symbol on the screen.
When I try to login with my username, no characters appear as I type.
I can login as a guest, but from there I can do nothing, because the keyboard is still inop and if I wanted to, for example, have the software updated, I need to type an admin login, which is impossible.
Thanks for your helpWhat happens if you close the lid? Sleep?
In your place I would use sleep state to reset PRAM, as it can resolve your graphical mess.
Your keyboard likely was not powered after SMC/PRAM failure, so you will need to open MBP cover without opening the lid and disconnect battery power cable with insulated tools from logic board, wait for 5-10 minutes, then try to reset PRAM while keeping cover -
The keyboard that is in the Mac is not functioning with the exception of the power button.
Since I am traveling, without a rental car, purchase of an external USB keyboard to troubleshoot and/or resolve the problem is not practical.

My HP Compaq powers on only when force i plug in. Doesn't turn on with power button!
I have a HP Compaq 6710b.. Its Over 6 yrs old..
The Issue is really annoying.. The laptop powers on only when i force plug in the charger pin and the laptop works fine after that..
But the laptop never turns on when i try to power on by pushing the power button!!
I couldn't understand the reason why...
Any thoughts about this issue? HELP!!
This question was solved.
View Solution.There are no settings in the BIOS that affect the use of the power button.
The power button works at the hardware (firmware) level.
Pressing the button is translated into action for the system board by logic conditions. There must be voltage at specific points in the power circuit. If the voltages are not present, then the power button will not operate. This could be caused by a failed resistor, mlcc capacitor or a faulty solder joint, if the power button has been tested and shown to be working normally. Even lint could cause this to happen. This can troubleshot by visual inspection and use of a multimeter.
Hi all,
This may be a solution for others but unfortunately not me..
My whole Power Circuit has been replaced with brand new circuit by authorised service personal in my country (will not HP, but he is an authorised service dealer of HP).. It was replaced/repaired a year ago and after that i hardly would have used the power button.. I also use the sleep mode and mouse to wake up.. (would have used power button not more than 20 times in one year. And especially during update shutdowns)..
So its better i will check with BIOS/CMOS setting and battery and get back soon.. Why i am mentioning this is because, for the past 8 months, when even i remove the battery and put back in and start up the lappy, the date goes back to 1980.. I guess this happens because of faulty/dead CMOS battery.. Because i had a similar problem with my Desktop too and when i replaced the CMOS battery, the date problem on my desktop vanished.. (Surprisingly, even some Digital cameras hav this issue too!!)..

A streamed movie will run smoothly for maybe 5 minutes. Then it will begin to buffer. The multicolored icon turns and turns and nothing happens. I try to go back to browsing but cannot. I try to close netflix but cannot. I try to close Firefox but cannot. Everything is basically frozen and the only way I can turn off my Mac is to press the power button.
Have you tried anything on this page?

Macbook Pro Boot Issue, White Screen with Apple
Having a similar issue with my macbook pro. When I press the power button, a white screen appears with an apple icon in the middle and a small cirle on the bottom that is like a timer. I thought that the computer might be downloading something, but I left it on for hours and the computer didn't get out of that mode. I have tried several things such as the installation cd, first aid repair, but both said repairs weren't needed and that the drives were fine. Any suggestions on why the computer is doing this? It's been several days and I shut if off, leave it off for an entire day and when I turn it on, the same screen with the apple appears and nothing else.
Any ideas are appreciated!
Thank you!Hi Claudiat :
You could try a SMU reset, which may solve your problem,
from Apple:
MacBook, MacBook Pro
If the computer is on, turn it off.
Disconnect the AC Adapter and remove the computer's battery.
Press and hold down the power button for 5 seconds and then release the button.
Reconnect the battery and AC Adapter.
Press the Power button to restart the computer.

My relatives 2009 Macbook Pro won't turn on and isn't taking a charge.
Holding down the power button has no effect and when the charger is inserted, there is no green or red/orange light. All outlets are functioning and the computer was working as it always had the day before. Help?
Hi Cygnus and Lyra,
Thanks for visiting Apple Support Communities.
If the MacBook Pro doesn't respond when the power button is pressed, or seem to recognize the charger, these troubleshooting steps can help:
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

Resetting your Mac's PRAM and NVRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Reinstalling Mavericks, Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
If you are not using Lion, Mountain Lion, or Mavericks then use the following procedure:

Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

MacBook Pro frozen on startup screen with progress bar and then it turns off
Hello, I have a MacBook Pro 15" of early 2012 with a i5 Intel, 4GB of RAM and a 500 GB HD.
I was installing the new suit of Adobe, when suddenly my Mac got frozen, vertical coloured lines appeared and the image on screen went distorted. I had to reboot the Mac by holding the power button until the screen turned off and when I turned it on, the lines appeared again and it itself automatically rebooted. Then the screen (now with no vertical lines) got frozen on the startup grey screen with the apple logo and the spinning wheel for hours with no response.
I tried to follow the steps of the official mac forums like verifying the HD with CMD+R and then Disk Utility, it says everything's fine; the same happens with CMD+S, no errors. I reinstalled Mavericks with the same CMD+R. I already reset the PRAM, SMC and performed a Safe Boot staring up in Single user mode and Verbose Mode and nothing, the same startup screen. I made too thins thing of holding shift until the progress bar appeared. Three days later (Today) I repeated the steps again and finally the verbose mode. Now, when I turn it on, the startup screen appears again (Apple Log and spinning wheel) with a progress bar. When it completes, the Mac turn itself off.
if you can help me, please. I don't know what else to do. The last thing is technical service.Hi again ggt15,

I have a 2010 vintage 13-inch MacBook Pro that has a 60 watt power adapter. I also have an older power adapter that is 65 watts. Is it okat to use the 65 watt with this MacBook Pro?
yes.
"For instance If you have a MacBook (13-inch Late 2009) that normally uses a 60W adapter, you can also use an 85W adapter with that computer. You would not use a 45W adapter with that computer; it would not provide enough power for that MacBook. Using an adapter of higher wattage than the adapter that came with the computer will not cause the computer to charge more quickly or otherwise operate any differently than using the adapter that came with the computer. "
