- macbook pro mid 2010
- reason for the problem: i believe because i removed the battery connection from the motherboard without shut down the system.
macbook pro does not work power on

My Mac book will not turn on? It charged all night and has never had a problem?

My MacBook will not turn on? Plugged in or without power cord attached. Charged all night. No previous problems?

Ok. Think I fixed it. I took the battery out for 10 seconds, reinstalled it and now it's up and running.

My buddy tried to help me install windows 8 on my new mac book and all he did was put the disc in and now it will not come out and my mac book will not turn off

I cannot get the windows 8 disc out of my mac book pro

Force eject a stuck cd/dvd
First try the normal methods to remove the disc. Drag its icon to the Trash can in the Dock or select 'Eject' from the File menu.
If you are running a virtual machine, e.g. VMFusion, ensure that the CD is disconnected from the virtual machine. This will sometimes allow the CD to now show up in Mac OS X.
Shut down the computer and start up whilst holding down the mouse button. This may take some time, but keep your finger on the mouse button right up until the disc comes out or the log-in screen has appeared.
If you have Toast Titanium installed on your computer, choose EJECT DISC from the menubar.
Sometimes you can successfully use the eject disc button in iTunes even if the disc is not visible to the Finder
Open Disc utility and choose the disc you wish to eject in the left-hand pane, then click on the Eject button.
Some Macintoshes have a paperclip hole that you can insert a straightened paperclip into, manually triggering the eject mechanism.
Open Terminal and type "drutil tray eject" to eject the disc/tray, and "drutil tray close" to close the tray.
If your computer has an eject button on the keyboard, restart the computer holding down the Option key. When the startup disk selection screen appears, let go of the option key and press the keyboard's eject button.

I'm trying to downgrade my icloud storage; however, my MAC book will not upgrade pass 10.6.8 and I don't have my iphone anymore. If there another way for me to do this?

I'm trying to downgrade my icloud storage; however, my MAC book will not upgrade pass 10.6.8 and I don't have my iphone anymore. If there another way for me to do this? I've tried everything I can find online and of course my coverage has expired and can't call the support team.

Hello Lara,
have you already called Apple and explained your current situation, because I don't see a way to downgrade your storage plan with a Mac only running Snow Leopard and without a iOS device running at least iOS 5.
Best regards.

16 mo young Mac Pro will not turn on. Dead. Why. No problems ever! Installed Yosemite and did not boot up after. Did that kill it? To young to die. What

16 mo young Mac Pro will not turn on. Dead. Why. No problems ever! Installed Yosemite and did not boot up after. Did that kill it? To young to die. What happened?what do I do now??????? Help!

Note that you don't have a Mac Pro as stated. Your profile says you have a MacBook Pro. Please clarify as they are entirely different computers. If nothing below works for you, then make a Genius Appointment and take it in for service.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities 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.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities 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. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, 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.

My Power Mac G5 Will Not Turn ON

My Power Mac G5 will not turn on. WOrked fine, then I went away for 7 weeks and now it doesnt turn on. Power/cord all fine. What can I do?
Thanks.

Same thing happened to my G5 dual (late 2004 model). Just did a quick search to find out "power supply unit failure" is most likely the cause.
Here are some useful links:
This guy replaced the PSU and documented the process:

Taking out the heat sinks to get to the PSU is a challenge. This link shows how:

This repair shop in Fremont CA seems to have pretty reasonable price to do the repair:

I have owned many Macs for the last 15 years. This is my first bad experience with Apple's product.

Replaced Optical Drive now Mac book will not boot up

I bought a second hand Mac Book Pro A1150 model. It did not have an optical drive so I bought one, installed it and now my Mac Book will not boot up. When I take the drive out the Mac Book boots up fine. I was told that the optical drive although used was tested and work when it was shipped out. I'm a little new to Macs but not new to working on computers. Is it common for a possible defective optical drive to casue a Mac Book pr to not boot up or does this sound like an issue with the optical drive cable, or possibly the logic board?

That is true. I cannot think of any way to test the Optical Drive without swapping it into a known correctly operating MBP.
A thought which probably may not be an issue. When I installed an Optical Drive in my old (2006) MBP, I remember seeing in the instruction manual an item called a grounding pad (which looked like a tiny steel brillo pad with out soap) which was missing in mine. The MBP worked and I essentially ignored it. Perhaps that may not be case with your situation.
My thoughts are that the Optical Drive is malfunctioning and the cause of your problem. Perhaps you should consider getting a new replacement from OWC. But that entails a $100 risk with no guarantees of success.
Ciao.

My iPhone will not turn on after a yet another blue screen of death. Please help!

As mentioned above, my phone will not turn on after a yet another blue screen of death. All of a sudden it turned off, and it wouldn't turn on for quite some time, even after I plugged it in the charger. It wasn't long after the screen turned on, but it only displayed a bright black. I decided to turn it on and off a few times. Nothing worked.
I have also tried to call the phone from another one. It was as if the phone was simply off.

Hello ZarinaUrum,
The article linked below details a number of troubleshooting steps that can help restore functionality to your iPhone.

Light will not turn off after installing new cyano cartridge

Light will not turn off after new cyano cartridge installed

I suspect that the ones that say they will work with Windows 8 on the box. If it does not say that, check the maunfacturer's website. They eventually will have to give Windows 8 support for the new cards or loose out to the competitors cards.
