MacBook Pro does not power up
So... Went to replace my bottom case on my mbp 15 a1260 model And now it doesn't power up. Battery drains while plugged in overnight. But no light on the MagSafe...that works on a different mbp so I know that's not busted. Question.... Des the left io board control the powering up or does the right logic board do that? I am trying to see if one has gone south. Can apple just take the logic boards to see if they work or do I have to bring in the whole reassembled computer?
Thank you.
Sig... I didn't screw up the replacement. I've dismantled and reassembled my mbp 12 times prior wi success each time and can do it by heart, but I still use the manual nonetheless. This time tho, it just doesn't power on nor charge the battery even tho the mag connector works.

New to Mac: My Pro does sleep, power on or power off consistently or efficiently. It freezes into a never ending spool. I have to press down the power off button to reset. I have updated my software.
If this is a new MacBook Pro, and you're within 90 days of purchasing it from Appe, contact Apple support. In the US it's (800) APL-CARE (800-275-2273)

My MacBook Pro does not appear to have power.
I have a 13" MacBook Pro, Mac OS X (10.6.3) that will not turn on regardless of what I do. With the MagSafe Power Adapter connected, its indicator light is green. When I press the battery indicator button, it indicates the battery is fully charged. The sleep light does not blink. After disconnecting the MagSafe Power Adapter, when I press the battery indicator button, it indicates the battery has no life (the first light doesn't even blink).
The electrical power outlet has power. When I use a new second MagSafe Adapter, my MacBook has the same symptoms and won't turn on.
My MacBook Pro does not have a user removal battery. I've tried all the recommended resets.
Any thoughts would be greatly appreciated.10.6.3 is pretty old for this machine but shouldn't create this problem.
So you did this:
Reset SMC
http://support.apple.com/en-us/HT201295
If no joy then:
Try a hard reset. Disconnect the battery (take the bottom off and unplug, use your fingernail.) and power adapter. Press the power button for 1 minute. Let the computer sit for 5 minutes, Reconnect and try to start up.
No? - Go through the same procedure and try to start without the battery connected.
The addendum to this would be to try a known good battery. -
My 13.3" macbook pro will not power up.The battery indicator light does not come on.The Mag safe charging light flickers green and red dimly.I had a cell phone connected to the USB port.
This didn't work for me, so I did a bit of searching and TONS of pages later in google, I found an answer. Here are the steps for people who also were in my situation:
1. Take off bottom case
2. Unplug battery - blurry image here: http://i.ytimg.com/vi/03cC79r5Dx4/0.jpg
3. Press and hold power button for 5 seconds
4. Plug a charger in, and it should start booting up
5. After shutting down again, reconnect the battery and close the case up
6. It works! (hopefully, if you guys had the same situation I did) -
MacBook pro does not recognize my WD external hard drive anymore
I use TIme Machine on my WD external hard drive. Everything was working great up until about a month ago. My MacBook Pro does not recognize my external hard drive anymore...I have done nothing differently than usual. I did search in previous discussions and tried rebooting both the hard drive and the computer.
The USB port is fine as it does recognize another external hard drive and also pen drives....Please help! I haven't backed up in a month and need to figure out how to get this to work soon. Should I call WD?Does the WD drive show in Disk Utility?
Many times, a USB port simply cannot provide the power a hard drive needs. It is not uncommon for any electric motor to draw more power as it ages. A drive that worked before can stop working when it gets older because age has made it tak more power than any USB port can supply. There are a couple of cheap things to try:
1) A "Y" USB cable---two plugs go to the computer and one to hte drive, giving a power boost.
1 Meter USB 2.0 A to 5 Pin Mini B Cable - Auxiliary USB "Y" Power Design for external hard drives.
2) a POWERED USB hub. That takes the power delivery burden off the USB port so it can deal with data.
WD bare drives are fine but their enclosures are not very Mac-friendly. One thing that has reported helping is to get rid of the proprietary formating that WD puts on their drives. If you don't have to share the drive with a Windows computer, use Disk Utility to erase and reformat the drive to Macintosh Extended Journaled. -
My MacBook Pro, does not start after pushing start button. The side bar starts and stops at half way.
Hy myneck,
Happy Holidays! The resource below may provide some steps to try if your MacBook Pro won't start.
Troubleshooting: My computer won't turn on - Apple Support
http://support.apple.com/en-us/TS1367
This article discusses what to do if your Mac won't turn on. To differentiate this from a display issue, be sure that when you press the power button:
You don't hear a startup chime.
You don't hear any fan or drive noise.
There is no video on your built-in or external display
If your computer has power but doesn't display any video, it may have one or more of these similar symptoms when you press the power button:
You may hear a startup chime.
You may hear fan or drive noise.
You may see a light from the Sleep LED (if your Mac has one).
Pressing the Caps Lock key on the keyboard causes it to light.
If any of these display-related conditions occur, see Troubleshooting: My computer has no video instead. Otherwise, continue with this article.
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
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.

If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).
I hope this information helps ....

I lost my iphone and my macbook pro does not show the icloud in system pref. how do i get icloud on my mac?
iCloud is only available in Lion, 10.7. You will have to upgrade to Lion in order to get into iCloud. If you transfered a .mac or .me address to iCloud through mobile me, or you have another device iCloud enabled, then you can log into the iCloud.com website.

My MacBook Pro does not recognize my Android Incrdible 2 cell phone and therefore I can not transfer any photos from my cell phone to my Mac. I was able to do this in the past, but can not do so now. I have not upgraded to any new software. My USB cable is plugged in properly and I just get an error message -- "No Android Device Found". What could be the problem?
I had the same issue with the Galaxy S4 trying to see what the hype was about and was my first and last android phone. With that being said unfortunately it is a hit or miss with the Mac recognizing an android device or not. It worked perfectly fine the first time around and then it stopped working for no apparent reason. Through trial and error nothing I did solved the issue. I did however plug it in my Mac and left it connected for about 30-40 min to charge for a bit and all of the sudden it recognizes the phone. So I just launched Android File Transfer and everything else became fluid after that. I have no explanation as to why it happened that way, but what I gathered from this is maybe you just have to let it sit for a minute while plugged in before the Mac recognizes it, after all they are opposing software. On a side note this is why I will always be an apple user, Iphones and the like never have this problem

Adobe Lightroom on MacBook Pro does not see my iphoto library
Adobe Lightroom on MacBook Pro does not see my "iphoto library"
Hello.
The problem is that the iPhoto library is inside of iPhoto. Lightroom won't let you select it because it's basically a shortcut to iPhoto. Try exporting the images you need or all of them, depending on what you need. -
