My MacBook Pro won't switch on.

My MacBook Pro won't switch on. I've tried charging it, but it wont detect the power (the green LED indicator won't light up). The pins are clean and the power source is fine. I've tried using a different charging cable, and the problem still exsist.
Please help!
Thanks.

You can try Intel-based Macs: Resetting the System Management Controller (SMC). But if this doesn't help then you may have a hardware failure.

MacBook Pro won't switch on

My 2011 MacBook Pro just died all of a sudden. There is no battery light on the side, the machine won't switch on despite trying the shift+Ctrl+option and power switch combo. Also the light on the mag power supply doesn't come, for some reason my 2 year old MacBook Pro is completely dead for no reason.
Can someone please help?
Many thanks.

Did you have any liquids around it? You may have water damage if you did. Did you ever charge your mac while it wasn't on reserve power or any percentage around that area? That sometimes weares out the battery. Ive heard with these cases you need a completely new mac. Not true! You can easily replace the battery or have it replaced. Actually, if you go into best buy's geek squad, they can trouble shoot any problems for you. The only problem is that it is usually expensive to fix. When I still had my PC, the geek squad guy said it isnt worth it to have my PC troubleshooted for him only to come back and say "Your PC has tobe replaced". You can also go to the Apple store where they are more directed on Mac products. If you have insurance fo your Mac, you should be fine. I know a Mac comes with the 1 year insurance but yours is 2 years old. If you have insurance, its your choice to easily get a new mac or get it fixed. Also, if you had icloud or backed up your mac, your files and data should be saved on another device. If not, that may be a problem if you had important files there. Things in the itunes store like music and books can be redownloaded. Hope this helps. Good Luck. Hope your Mac feels better.

Mid 2010 Macbook Pro won't switch to Nvidia graphics.

I have been playing Starcraft II on my Macbook Pro (i7/4G RAM/15" Display) for a few weeks now. Yesterday my frame rates dropped through the floor. The game was nearly unplayable. I thought initially that the level I was playing just had too many units. I re-played one of the tutorial levels and it too was slow. I lowered the graphics quality settings in the game and it didn't get much better.
I put the game into windowed mode (rather than full screen) and started playing. I pulled up the system profile tool and saw that the intel graphics were active, not the nvidia graphics.
I went into system preferences/energy saver and shut off automatic graphics switching and it was still using the Intel HD graphics.
This happens all the time, plugged in or not.
Any ideas?

Thanks for your suggestions. I ended up taking it to an Apple store and they ran diagnostics on it. It came up clean.
The tech powercycled it and cleared the PRAM (?) by holding cmd-option-p-r while booting.
I am not sure what fixed it, but Starcraft 2 framerates are back where they used to be.

Calendar on Macbook Pro won't synch with iCloud

Calendar on my Macbook Pro won't synch with the Calendar on iCloud. I tried a number of times to delete Calendar from iCloud in System Preferences then restart the laptop. I also switched the 'enable' function on and off in Calendar Preferences. I restarted after every attempt and also refreshed. It looks as if it's updating but then nothing happens and the triangular, exclamation mark appears, grayed out, next to the iCloud icon in Calendar. I saw an answer in the Apple Support troubleshooting section regarding this about the server having to access port 80 or 443. Could this be the problem and if so then how would I make any port accessible to the relevant server? I'm not having this problem with my other devices or computer.

Hello Wateru,
Thank you for providing the details of the calendar issue you are experiencing with your MacBook Pro. You have taken some really good troubleshooting steps already. I recommend continuing with the steps in the sections titled "General troubleshooting" and "Troubleshooting on OS X" in the following article:

My new Macbook Pro won't start.

Hello. So today i got my new MacBook Pro 13''. I started to use it and competely emptied battery. Now i can't turn it on, it don't charge and my MagSafe charge don't blink. What do i do? It's my first Mac and first problem in first day, it makes me mad.

I'm having a similar problem and I'm ready to explode. I have a huge work deadline tomorrow and can't get the work done. My 4 month old macbook pro won't charge anymore. I'm now on an old pc desperately searching for help.
I switched to my first mac because everyone said how great they were. Since when does a nearly new laptop stop charging? apparently this is a common problem and my sales person did not inform me when I asked specifically about potential bugs. I am furious, frustrated and very unhappy with this. Apple, you suck tonight.
Here's the problem: The light on the magsafe adapter did not work this evening when I tried to charge it. I did nothing out of the ordinary. It was on the desk and I plugged it in as usual. I spent an hour on the phone and online trying to get apple support to no avail. Apparently their 24/7 line is not 24/7 in Canada?
I cannot remove the battery as the site says, so I'm completely screwed at the mercy of this bullcrap brand. I did everything advised on the site, including checking the SMC and the cord itself. With only 20 minutes left and the battery ticking, I tried to email myself all the files I need, but they're huge and just when it was near finishing, the battery went from 10 to 21 minutes and it shut down.
Now it won't turn on, of course. The little button on the side has only one green light flashing. The adapter does nothing. NO red or green like before.
I am at my cottage and do not have an apple dealer nearby. Who can I scream at for this? All my previous computers could be easliy fixed when things go wrong. Remind me what is so great about this overpriced mean little machine!%^%!^*%&!(
WHY does a NEW laptop that costs a premium have such a fragile adapter / battery? Is there another adapter I can use to charge it? I'm at my wit's end.

My macbook pro won't stop making noise! It sounds like the fan but I'm not sure. Any ideas?

my macbook pro won't stop making noise! It sounds like the fan but I'm not sure. Any ideas? It's really worrying me because I haven't had it for up tp 2months and last week everytime I switch it on it makes sooo much noise. And I treat like an egg so I don't understand whats going on.

Hey,
My friend had a very similar issue to yours. The issue came down to the pins of the MagSafe not meeting with the MacBook perfectly causing the lights and the transfer of power to be wacko. I'm not sure if this is issue that your experiencing, but its worth checking out the pins and the MagSafe area on your MacBook for debris.
Troubleshooting Magsafe power adapters with stuck pins
If that is all clear, then I would suggest you call AppleCare or take it in to an Apple Store to have it checked out.

My MacBook Pro won't let me mount my external Hard Drive. Just trying to restore my iTunes library.

My MacBook Pro, less than a year old, started acting weird. I backed everything up, took it in to Best Buy, who sent it out to Apple Repair and they put in a new motherboard.
It's running on Mac OS X Version 10.7.4
Now I am trying to put everything back on the computer from my external Maxtor 80GB Hard Drive. MacBook Pro won't recognize the external drive.
I tried Disk Utility. I can see the external drive, and did a repair disk and verify disk. Several times. Each time it says "This partition map seems to be ok."
However, I am not able to mount it, as that option is greyed out and i can't select it.
Also, under the Icon for the external hard drive, it has the Macintosh HD Icon (essentially my computer). I tried to restore this way, didn't work.
I need this to mount, as it has all of my itunes stuff on it; dozens of my sons movies, and my entire iTunes library.
PLEASE HEEEEELP!! HOW CAN I MOUNT THIS EXTERNAL HARD DRIVE? Thank you in advance

I was messing around with .kext files in the MacintoshHD and now my MacBook Pro won't start up.

I was messing around with .kext files in the MacintoshHD and moved the system.kext and two others to my desktop and deleted the originals and now the MacBook Pro won't start up. All I get at start up is the apple icon then a bunch of text shows up part of which says Mac OS version: not yet set. then the apple icon turns into the power icon and tells me to turn off the computer. I've tried reinstalling from the install DVD by holding down option when powering on and selecting the install DVD and it just goes to a white screen with the apple icon and stays like that. I didn't have the disk utility on my Mac before this happened because I deleted it to make room on my computer a while ago so I'm not sure if that's why it won't load the install DVD but anyone who knows the solution to this with out going to get it repaired would be greatly appreciated. Thank you!

Never mind my dad just found the original install DVD and that worked. Before I was using an install disc that Apple sent me for another issue I was having, but thanks for replying so quickly and trying to help on this Thanksgiving day!!!

My MacBook Pro won't connect to the Internet, but my phone and PC will.

My MacBook Pro won't connect to the Internet. My iPhone has no problem doing so, and neither does my PC. I think it's something to do with my DNS, but I'm not sure. My network connections say that both my Ethernet or FireWire are failed. What's wrong with my MacBook? Is there a simple way to fix this?

Hello Rattisate,

MacBook Pro won't play .mov or .wmv files.

Since "upgrading" to Lion my MacBook Pro won't play .mov or .wmv files, all I get is a black screen and the audio. It's so frustrating!!
I've read many other posts all along the same lines and wherever possible I've tried to follow the advice which has been given but nothing works.    I've updated all the drivers I can and I've even reinstalled Lion, nothing makes a difference.
I'm not really looking for any more advice, all I want is someone from Apple to read these posts, realise there is problem and get working on a fix or update.
I had no problems when running Snow Leopard and it would seem, looking at everyone else's problems, that the common issue is Lion.   Seriously, this is one area where Lion is a backwards step.   It should just work (like most things from Apple), but it doesn't.
Personally I believe there is a problem with Lion but from what I've found out from speaking to friends with other Apple kit, this might be a random issue only affecting some people as some have said they've had no problems while others have had the same issues as me.    One guy reinstalled Lion and it resolved the issue for him, I've not been as lucky.
As I say, I'm not really looking for more advice, simply some sort of update from Apple to fix it.   PLEASE!!!

This is a peer-to-peer user forum. Perhaps you would see more action if you and others would file a formal "Bug" report with Apple QuickTime technical people rather than repeatedly reporting a possible problematic problem which may or may not affect others on a random basis. QUICKTIME PRODUCT FEEDBACK
Since you aren't seeking further advice here is what I have observed. Not being a regular WMV file user, I had to create my own sample file to test—a WMV 9 file containing WMV3 compressed video and WMA2 compressed audio. Since I normally use QT 7 as my primary media player, I also stored the WMV data in its partially decompressed form in an MOV file container to avoid pre-playback delays in "classic" player routines and also provide a secondary playback test of MOV wrapped content. These files play as follows using the Flip4Mac component/player support and uncoded URL uploads:
QT 7.6.6 "Open File" - both files play correctly.
QT 7.6.6 "Open URL" - both files play correctly.
QT X.1 "Open File" - WMV file plays correctly. MOV file plays video without audio.
QT X.1 "Open Location" - WMV file appears to open but plays with "black" screen and no audio. MOV file plays video without audio.
VLC "Open File" - WMV plays correctly. MOV file doesn't open,
VLC "Open URL" - WMV file plays correctly. MOV file appears to open but nothing plays.
MPEG Streamclip "Open File" - both files play correctly.
MPEG Streamclip "Open URL" - both files play correctly.
GarageBand - WMV file will not import but MOV file does.
iTunes - WMV file will not import. MOV file container is accepted but as soon as iTuness sees the compression formats, it aborts import.
Safari - WMV file URL auto-downloads and playes in the QT X.1 Player. The MOV file URL opens and plays in Safari.
As you can see from these results the files do play but are subject to many different constrints based on old/new video technology support, independent QT subsets and/or container trapping constraints. In short, individual user results will depend on presence/absence of component support, actual compression formats, file container, application being used, and how the application is being used. Unfortunately, most users here can't or won't provide the prerequisite information or a sample file for independent examination. This makes it next to impossible to give advice in these matters or categorize the specific nature of the problem.

Hi! My MacBook Pro won't start! HELP !!!

Hi! My MacBook Pro won't start! I have tried everything I can think of like Safe Mode (doesn't work), Recovery (does not find Recovery Drive), Booting with OS Snow Leopard Cd (doesn't work)...
I have really no clue about what to do now... I paid quite a lot of money for this computer and am pretty short of money nowadays! Would like to repair with help rather than having to take it to Apple Store.
Has anyone had this same problem?
All I get is white screen + grey Apple and spinning grey disk... it's 100% frustrating! Any help would be more than welcome since I think i've tried EVERY SUGGESTION on this Support Center and Youtube videos...
This MBP is from 2011, runs on OS X 10.6.8
I tried booting with OS X Snow Leopard CD, it didn't work! (my cd player works! recognizes the Snow Leopard CD, but then never opens it... goes back forever to the with screen + apple and spinning disk)
I don't care about the content, it's OK if i lose all DATA... I just want to bring this Mac BACK TO LIFE!
When i run coomand on root# fsck -fy --> RESULT = my HD was checked and seems to be FINE!
Thanks

Please make a Genius Appointment and take it in for service.

My MacBook Pro is not switching on and my charging light is very dim green

Hey ! My MacBook Pro is not switching on. I was trying to charge my iPhone through the lead attached to the MacBook. I suppose the iPhone charging lead might not be a original. Hence it kept saying that this accessory will not work. So I took it out. As soon as I did that my mac switched off and it would not switch on again. The charger light went really dim green. It usable is more brighter. I've waited for a while. It's not switching on. I was trying to do smc reset but I suppose if I'm doing it right it's not working. I was reading online and I didn't find much help. I live in Pakistan so I can't go to apple store. Please tell me a solution !!?
