Why does my mac book pro screen go black when it goes to sleep and then will not light up again unless I unplug the power cord
When I either leave my mac book pro open, but idle long enough for it to go to sleep or close the top and put it to sleep, the only way to light up the screen again is to diconnect the mag. connect power cord. Any ideas why and/or how to correct this problem?
So this is what I got when I took my computer into the apple store to have it diagnosed.
After the apple technician performced several tests, the only thing that fixed the issue was an SMC reset. Based on this he figures it is probably a software or firmware issue that is going on. He is a little concerend how ever that the fans of the comupter don't reach maximal rpm when the computer is displaying the issue. So he recorded the problem, and told me to just perform the SMC reset as needed for the next couple months and wait for a new update from apple. If the issue persists I am to go back to the apple store and they will take the appropriate steps.
He said an SMC reset doesn't hurt the computer in any way, so its safe to do. I am gonna contact blizzard and let them know about the issue as well because if it is software, it could be their game (Diablo 3) that is causing the issue as well. If I hear of anything new i will let you know. So get on the blizzard form and let them know of the issue to fix the problem faster.
Thanks for your help,

Why does my mac book pro not show in 1080p on my flat screen
why does my mac book pro not show in 1080p on my flat screen. My mac bookpro always showed in 1080p on a Sanyo Plasma screen. Now when I connect mac book pro I get a blank screen. It will display in 720 but not 1080p. Also will show in 1080i but pictures flicker.
davenug,
given how much we currently know about your MacBook Pro, why do you think that we would know the reason? Please help us to help you by providing relevant information about your MacBook Pro — which model is it? Which version of OS X is installed on it? Is its battery fully charged? Is its AC charger working properly? &c. -
Why does my Mac Book pro keep restarting
why does my Mac Book pro keep restarting and how can it be fixed
It would be nice if you could include a kernel panic log to verify that your problem is...
Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
Kernel Extensions in backtrace (with dependencies):
com.apple.GeForce(6.4.0)@0x82ac4000->0x82b7afff
dependency: com.apple.NVDAResman(6.4.0)@0x834a0000
dependency: com.apple.iokit.IONDRVSupport(2.2.1)@0x82fd3000
dependency: com.apple.iokit.IOPCIFamily(2.6.5)@0x7a802000
dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
com.apple.nvidia.nv50hal(6.4.0)@0x83c05000->0x84019fff
dependency: com.apple.NVDAResman(6.4.0)@0x834a0000
com.apple.NVDAResman(6.4.0)@0x834a0000->0x8378dfff
dependency: com.apple.iokit.IOPCIFamily(2.6.5)@0x7a802000
dependency: com.apple.iokit.IONDRVSupport(2.2.1)@0x82fd3000
dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. The unfortunate thing is that many people have passed the “three years from date of purchase” now and Apple is not honoring the free logic board replacement for many users. Some dealers seem to be making some exceptions for those past the three year mark, but don’t count on it…
Good luck,

WHY DOES MY MAC BOOK PRO SHUT OFF ON ME? SO FAR THE INFO I GOT 4 IT IS A MAC OS X VERSION 10.7.3 THE PROCESSOR IS 2.4 GHZ INTEL CORE 2 DUO MEMORY IS 2 GB 667MHZ DDR2 SDRAM I DON'T KNOW HOW OLD IT IS BECAUSE I BOUGHT IT USED SORRY I HOPE THIS HELPS THANK YOU
Sounds to me like you may have gotten a machine with hardware issues, but it's hard to say. It will shut down if it gets too hot, but that's not a normal occurrence. I have never seen a MacBook Pro shut down due to heat, even after lengthy 3D gaming sessions where the fans are running fast and the bottom of the machine is unpleasant to touch.
First thing I would try to do is reset the SMC. If that doesn't help, erase the hard drive and reinstall the system from scratch, which you should always do with a used machine anyway.
If a fresh system doesn't help, you'll need to get it checked out by Apple.
Edit: Oh, and sig is absolutely right... please don't post in all caps! It's very irritating. -

How about more info so a diagnosis and help can be formulated? Mac model (size), RAM, OS version, age, battery status? What are you doing when it happens? How often? And if you want to be really abundant, pertinent logfiles? -
When turning on my Mac Book pro before it get to the log in screen it has a blue screen for a couple of second the goes to the login sreen. It seams to take some time to complete the login to my computer.
can anybody give me some help with this problem.
Thank youThe cable connections have (so far) solved this problem for my situation. Even though the monitor's DVI cable was firmly connected to the mini Display port connector, when I touched it the attached monitor would go 'blue' or lose its connection entirely. After disconnecting and reconnecting this junction the monitors would still take a hit on touching the connection. I also checked the connection of the mini Display port connection to the graphics board and could not push it in any further. However, after a second go-round I unplugged this connection to the board and reconnected it. I am certain it was fully inserted the first time. But, connection contacts can oxidize over time and sometimes it may just need to be disconnected and reconnected to 're-wipe' the connections. This effectively cleans them at the point of contact. So in my case I'm thinking it was the connection age that was an issue more than a 'loose' connection. Either way, I haven't had this issue for the past two weeks.

Why does my mac book Pro pick up wifi but my new ipad wont in the exact same position in my house?
I sit in my lounge with my mac book pro and it picks up my home wifi perfectly yet when i sit with my ipad, sometimes it works and picks it it but then at times it looses the connection and I cant find the hub?? why is this and is there anything I can do to stop it from happening?
Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
iPad: Issues connecting to Wi-Fi networks http://support.apple.com/kb/ts3304
iOS: Recommended settings for Wi-Fi routers and access points http://support.apple.com/kb/HT4199
Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

When I begin to play Diablo 3 with my fairly new 15" mac book pro with retina display, every now and then my computer will be really laggy when playing it (frame rate of under 5). Normally its performance is really fast with a frame rate of about 40-60 frames per second depending on the resolution used. When this happens I have performed a SMC reset and it fixed the problem. However, every few days it will act up again and I will have to do an SMC reset again. It has now happened again for the third time and I am affraid to continue to perform an SMC reset, is this bad for my computer? Should I take it in and have them trouble shoot it? Any help would be greatly appreciated to figure out what is wrong. Thanks.
So this is what I got when I took my computer into the apple store to have it diagnosed.
After the apple technician performced several tests, the only thing that fixed the issue was an SMC reset. Based on this he figures it is probably a software or firmware issue that is going on. He is a little concerend how ever that the fans of the comupter don't reach maximal rpm when the computer is displaying the issue.

My mac book pro screen is black
I have a 15 inch mac book pro. I dont know the year or type because i got it as a persent and opened it later. The battery is removable and it is silver. When starting it up it chimes like it normaly would. I just stoped working one day when i got home from school. If i change the volume i can hear the indicator that it is changing. I know you can solve it because other people had the same problem as me. Also the keyboard doesnt work so i use a different one. Can i get this solved without taking it to the apple store. Thanks.
If the battery is removable, it is pre 2009.
Try these 2 things, if no joy take to an Apple store for a FREE diagnosis, they will then give you your options.
SMC reset;
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery.
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer.
PRAM reset:
ote: To print these instructions, open Help Viewer’s Action pop-up menu (looks like a gear), then choose Print.
Shut down your Mac.
Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on your Mac.
Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears. Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
Release the keys. -
HT1349 why does my mac book pro start up but contunitues to try to load
can someone help with my mac book it starts up logo appeares then the busy signel conuines to try to load but nothing happens?
Try starting your Mac in Safe Mode.
Restart your Mac.
Press and hold down the Shift key immediately after hearing the startup tone. Be sure NOT to press the Shift key before the tone.
Release the Shift key when you see the Apple logo and the spinning-gear appear.
When the Login Window appears, log into your account.
If you Mac starts up, then the issue may be a problem with one of the Startup items, Login items, or a 3rd-party kernal extension (if you got a kernal panic screen during startup.)
If your Mac does not start up, use the Startup Manager to see if the startup disk is detected. Note: By default the startup disk is Macintosh HD.
Try running the Apple Hardware Test. This test is included on the Installation CD that came with your Mac. -
Why does my Mac Book Pro operating OS X version 10.7.4 startup so slowly?
My Mac Book is less than one year old and it is already bogging down considerably and operating slowly. The problem began after I inadvertently filled the hard drive to capacity. After noticing that the hard drive was full, I cleaned out half of the space. I cleaned out the downloads, trash, archived large files, and moved misc. information to an external storage device. However, since filling the hard drive my computer takes much longer to reach the login page--usually a minute or more. After logging in the computer takes another minute or longer to fully start up. I have also noticed that the overall performance is more sluggish now. Any suggestions? I look forward to your help and comments. Thanks!
Launch the Console 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 Console in the page that opens.
Step 1
Select "system.log" from the file list. Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged during the time something abnormal was happening. That time might be before or after the boot.
For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes after the boot time, not before. If the problem is a system crash or freeze, post the messages from before the boot time, when the system was about to crash or was failing to shut down. In either case, please include the BOOT_TIME message at the beginning or the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
If the log doesn't go back far enough in time, scroll down in the Console file list to /private/var/log/system.log.0.bz2. Search that archived log, and if necessary the older ones below it, for the same information.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Do the same with kernel.log.
Step 3
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall or hang logs — they're very long and not helpful. -
