MacBook Pro won't feed - need to disconnect/reconnect the battery.
I have a 'early 2011' MacBook Pro 17 "which does not illuminate when the power switch is pressed. He worked normally in the last time it was used.
I'm a PC I / specialist t so I did some fault finding. Here are the results and measures, I tried:
- Power button and no indication button has been pressed.
- Button on the side and he said fully charged battery.
- Adapter a/c and LED power connector attached LED lights up in green as it is supported.
- You press the power button - still no indication of any attempt to power on.
- Let Reset SMC pressing SHIFT, control, Option, and power switch. All released. You press the power button - still no indication of any attempt to power on.
- Power button which is held down for 15 seconds, released, then no hurry once - no change.
- Disconnected a/c power.
- Removed the back cover.
- Battery disconnected from the system board connector.
- Connected a/c adapter and power button pressed - no change.
- Disconnected the a/c adapter.
- Back in the connected battery system board connector.
- Joint a/c adapter and the system performed a reset, then IPL upward and ran normally.
- System "Shut down" and then press the power button - would not be back.
- Removed the a/c adapter and pressed the power button - still wouldn't back off.
- Disconnected a/c adapter, disconnected the battery, battery reconnected to the system board. Power button - will not turn on.
- Repeat the procedure which worked previously - a/c offline, disconnected battery system board, connected a/c, press button power (no signs of activity), disconnected a/c, battery reconnected to the governing body of the system, reconnected a/c and it reset and power!
- Let system and then "reset" (instead of closing) - it restarts correctly.
- Shut down the system and then I tried to power - will not turn on.
- Bottom line: it seems that the procedure which will get the system starts, after it is closed: disconnected a/c, disconnecting the battery system board, connected a/c, press power button (no signs of activity), disconnected a/c, reconnected battery to the system board, reconnected a/c and it resets and starts.
OK, so you MacBook Pro experts out there... what seems to be the problem and what measures would you recommend I take?
THX,
Jeff

Hello
You most likely need a replacement battery for your Macbook. You can bring to an Apple Store and ask them to replace the battery. If you have Applecare, it should be free. They can also do it for free if there is no visible damage to the product (think it's a manufacturing defect). You can request the service directly from Apple or a local Apple authorized service provider.
You can go here for more information in the center of Apple - Support - response Service

When I restart after turning off the power, the system is back to normal until I need to close again.

Just in case, run disk utility.
Open utility disk located in Applications/Utilities
Then select the disk to boot on the left and then select the first aid tab and then click run.
If disk utility indicates that the disc seems to be OK, you are finished. Otherwise, you must repair the disk.

Why my Macbook Pro boot used place in any mode but the comments?
My Macbook Pro almost 5 years, worked very well, then the beech ball began to come a lot and programs would take forever to load. I tried to stop him to restart in diagnostic mode, but it would not closed and just hung up for about an hour. I hit the power button to force a power down and when I went to turn it on again, it does not start in safe mode or diagnosis. He goes to the login screen and gives me the choice of my log in or invited, but starts if I select my journal going through the motions leading to the top of the load bar, but before he gets to the end, she stops. I can start in guest mode and access the internet, but I can't do anything from there. If I click on the Apple, it gives me the opportunity to go to the startup disk, and when I click it, it asks which drive I use, (only one option, HARD drive), but when I select it, there is nothing there.
I can't really afford a new Macbook for now, and until the last few days it works very well, so I prefer to get it fixed to the top if I can, so any help is appreciated.
See you soon,.

Hey there,
I see your message that you are unable to connect to your user account, even in safe mode. I would like that you try to start your computer in OS X Recovery and then try to repair your hard drive. If the problem persists after that, you can reinstall OS X.
To start your computer from recovery, restart your Mac and press the command and R keys at startup.
Hold these buttons until the Apple logo appears. After your computer has finished starting upward, you should see a desk with an OS X menu bar and window OS X Utilities with the above options. If you see a login window or your own office instead of the utility window, it is possible that you do not press command + R early enough. Restart your computer and try again.
Choose the option you want to use from the utility window or in the Utilities menu.
Take care.

I have a Macbook pro (2011 model). It gets stuck on the start screen on to half way through commissioning. This happens whenever the mac turns on. The problem is solved when I reinstall Yosemite to boot to Recovery Mode disk utility. However, the next time you start, the startup process is blocked to halfway to new (on the screen with the toolbar and the status of apple). I want a more permanent solution to reinstall the operating system every time. Would appreciate someone's suggestions and thanks in advance.
Replace your hard drive.
You have a backup of trust? If not, buy a disc of exterrnal for that as well.
The progress bar from the left end at the beginning of the commissioning indicates that your drive has been so damaged, it could not be mounted. Five minutes of progress bar is shown as it does the equivalent of disk utility (ERD [Directory]). If you have reinstalled several times and the problem is not fixed, your drive is in solid form.

While Adobe says his record the FIRST 9.3 update plug-in for Adobe Photoshop CS6 (Extended) strives to convert directly from the RXRII of Sony camera RAW files, is not. Maybe my MacBook Pro OSX El Capitan 10.11.5 exceeds the 10.11 noticed on the Adobe Camera Raw graph?
Please notify.
CS6 can only be updated up to a maximum of ACR 9.1.1 to install cab 9.3 in CS6, attempts fail. You can check which version you have by any plug-in / Camera Raw (I think on a Mac).
You can register CC (LR+PS@$120/yr=$10/mo is the least expensive) or use the DNG Converter to DNG for raw files and the DNG, but not the native raws, open in your older software.
The DNGC is here: http://www.adobe.com/downloads/updates/
