After 10.5.5 update, MacBook Pro LCD not working.
After I updated to 10.5.5 my MacBook Pro worked fine, until I put it to sleep. Now, the screen won't come back on even after restarting and removing the battery.
Also, I can't even get an external monitor to work.
I can hear the volume idicator sounds working when I adjust the volume so I know that the computer is working, just not the screen.

No guarantee but there are two things that sometimes help:
Reboot into the Safe mode (hold down Shift key on boot) but when you get to the login screen click restart.
If that doesn't help, try resetting the PRAM.

After 10.7.4 update macbook pro won't sleep
after 10.7.4 update, macbook pro won't sleep.
Test after each of the following steps that you haven’t already tried:
Step 1
▹ System Preferences ▹ Energy Saver ▹ Power Adapter ▹ Wake for network access: uncheck. You may need to unlock the preference pane by clicking the lock icon in the lower left corner and entering your administrator password.
Step 2
▹ System Preferences ▹ Energy Saver ▹ Schedule… ▹ Start up or wake: uncheck
Step 3
▹ System Preferences ▹ Print & Scan ▹ Open Print Queue...
Check all printers for unfinished jobs. Deal with any you find.
Step 4
Disconnect all wired peripherals except keyboard, mouse or trackball, and monitor, if applicable.
Step 5
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select All Processes from the menu in the toolbar, if not already selected. Enter “powerd” (without the quotes) in the "Filter" text field. Select the powerd process and click the Quit Process button in the toobar (stop-sign icon.) In the sheet that opens, click Force Quit. You’ll be prompted for your administrator password. The process will be relaunched immediately.
Step 6
Boot in safe mode and log in. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the Mac OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
If sleep now works as expected, go on to the next step.
Step 7
Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
Step 8
If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
If you still have the sleep issue after booting out of safe mode, post again. -

My MacBook Pro keyboard not working correctly after Win7 bootcamp installation.
Installation went well but when I boot either with OSx or Win it always keeps Windows keyboard.
How can I have Mac keyboard in OS boot and Win keyboard in Win boot?Hi - I have the exact same model as your MacBook and had a few questions as mine is acting up. I upgraded the ram to 8gb (2x 4GB ram) and ever since then my computer has not been running as smoothly and the start up time is horrendous. Have you encountered this problem? And if so how did you fix? What would you advise me do?
I was thinking of reverting back to the original factory 4GB then rebooting the entire computer. Any suggestions?
Thanks in advance!

The sound on my macbook pro is not working
The sound on my macbook pro is not working. When I increase the sound, the icon appears as if everything is working, but no sound comes from the speakers. Earphones don't work either. I have tried a PRAM reset but at times, this doesn't even work. It's really frustrating having to restart my computer every time I want the sound to work, and even when I do that, theres a 50 50 chance of it working again. It generally happens after my laptop goes to sleep and I wake it up. Has anyone else had this problem and fixed it or even know what caused it?
There are a lot of discussions around the earphone jack but I have checked that. I've tried a PRAM reset which hasn't worked, and my sound output is set to Internal speakers.
HELP!!Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
Highlight Internal Speakers / Headphones
Make sure Mute is not enabled.
2. Remove the headphone.
If you see red light in the headphone port, plug the headphone
in and out of the port 5 or 6 times to flip the microswitch inside.
Sound output may be stuck in the digital mode.
3. Reset SMC. http://support.apple.com/kb/HT3964
Choose the method for:
"Resetting SMC on portables with a battery you should not remove on your own".
4. Applications > Utilities > Audio MIDI Setup
Audio Devices window
Side Bar
Click the Built-in Output.
Under Mute any of the boxes checked? If so, uncheck it. -
The sound on my Macbook Pro does not work.
The sound on my Macbook Pro does not work. When we press the volume buttons, the sound icon pops up, but the bar is full with a small "Does not work" circle below it, and nothing happens when I hit volume up or done. I went into system preferences, but there aren't any options there that I can see to change it.
"Unfortunately, it doesn't provide any help for a MacBook Pro, other than indicating to call Apple Support" (sic).
Au contraire. TS1574's title and affected products are thusly:
"Troubleshooting issues with no audio from built-in speakers on Macs
Products Affected Mac mini, MacBook, MacBook Pro, iMac"
As a result, the instructions of the article are relevant. To be sure, follow those steps, the last of which is to contact Apple.
So, by way of reminder, here are the steps to troubleshoot the audio on your MacBook Pro. There is no red light, so the port is likely fine. Headphones work, so clearly your sound card is fine.
1. Ensure an incorrect version of OS X is not installed. If one is, then reinstall or erase/install after backing up your data.
2. Remove any external audio devices from USB, firewire, etc.
3. Open Sys Prefs > Sound > Output
If Internal Speakers is listed, select it and test again.
If Digital Out is listed, confirm again that all external audio devices and cables have been removed.
If mute is selected, unselect it.
If the volume slider is low, raise the volume.
If the above simply doesn't fix it, the issue may be a corrupted plist. Apple Support might be able to help troubleshoot the issue further, per the last step of TS1574.
I hope it gets resolved for you. Good luck. -
ICloud sync with MacBook Pro does not work
I've installed iOS 5, updated Lion to 10.7.2, marked Calendar and Contacts sync in System settings for iCloud on my Mac. However iCal and Address Book sync between iCloud and Mac (MacBook Pro) does not work though there is no problem in syncing between iCloud and iPhone. Whether I create new event or contact, change existing one or delete existing one in iCloud this change is not reflected on my Mac and vise versa. I could not find a solution in this site or in forums.
Yep, worked for me, too and now contacts and calendar seem to be syncing perfectly. We'll see if it lasts.
Thanks for your answer. -
IMessage (Macbook pro) suddenly not working!?
My imessage from my macbook pro is not working! When I send a message, it automatically displays a red exclamation point and the name of the person I am sending it to turns red. When I click on that it tells me that their number is not registered with imessage! I've sent imessages before (today even) and I don't know what happened. I think I may have messed with some preferences because I was trying to change security preferences, but maybe I accidentally clicked something I shouldn't have? I know it is me because I get the same error for every person I try to message. It works from my phone, though.
This could be a complicated problem to solve, as there are many possible causes for it. Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
Before proceeding, test on another network, if possible. That could be a public Wi-Fi hotspot, if your computer is portable, or a cellular network if you have a mobile device that can share its Internet connection. If you find that iMessage works on the other network, the problem is in your network or at your ISP, not in your computer.
Step 1
Check the status of the service. If the service is down, wait tor it to come back up. There may be a localized outage, even if the status indicator is green.
Step 2
Sign out of iMessage on all your Apple devices. Log out and log back in. Try again to sign in.
Step 3
Restart your broadband device and your router, if different. You may have to skip this step if you don't control those devices.
Step 4
From the menu bar, select
▹ About This Mac
Below the "OS X" legend in the window that opens, the OS version appears. Click the version line twice to display the serial number. If the number is missing or invalid according to this web form, take the machine to an Apple Store or other authorized service center to have the problem corrected.
Step 5
Take the steps suggested in this support article. If you don't understand some of the steps or can't carry them out, ask for guidance.
Step 6
From the menu bar, select
▹ System Preferences ▹ Network
If the preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advanced button and select the Proxies tab. If the box marked SOCKS Proxy is checked, uncheck it. You don’t need to change any other settings in the window. Click OK and then Apply. Test.
The result may be that you can't connect to the Internet at all. Revert the change if that happens, or if iMessage still doesn't work. Remember that you must Apply any changes you make in the preference pane before they take effect.
Step 7
Select from the menu bar
▹ System Preferences… ▹ Flash Player ▹ Storage
and click
Block all sites from storing information on this computer
Close the preference pane.
Step 8
Make sure you know the ID and password you use with iMessage. Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Use the search box in the toolbar of the Keychain Access window to find and delete all items with "iMessage" in the name. Log out and log back in.
Step 9
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
If iMessage worked in the guest account, stop here and post your results.
Step 10
Boot in safe mode and log in. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. After testing, reboot as usual (i.e., not in safe mode) and test again.
If iMessage worked in safe mode, but didn't work when you booted out of safe mode, stop here and post your results.
Step 11
Reset the NVRAM.
Step 12
Reinstall OS X.
Step 13
If none of the above steps resolves the issue, make a "Genius" appointment at an Apple Store, or contact Apple Support. -

SemakoYuu can try to reactivate your iSight camera by opening up iMessage.. navigate to Preferences/Audio Video,and then click on Camera. IT shoudl be grayed-out if you only have one camera hooked up to your machine. If you have an external camera, then disconnect it from your machine.
