My 2008 MacBook Pro will turn on but the screen is completely black. I have no idea what going on. Can anyone help me out??

My 2008 MacBook Pro is turning on but the screen stays black. It makes the turning on noise but nothing happens after that. Can anyone tell me what wrong with it and maybe help me out??

Make a PRAM reset > http://support.apple.com/kb/HT1379 Also, reset the SMC > http://support.apple.com/kb/HT3964
If they don't work, that may be a display or GPU issue. Take your MacBook Pro to an Apple Store or reseller. If you want to know which is the part, connect an external display

So my 2008 MacBook Pro will turn on but the screen is completely black! I'm kinda feeling out, can anyone help me??

Is it normal for my macbook pro to buzz when i turn it on?

hello everyone!
I am one of the many people that got a mac for christmas this year. when I opened it, it looked like a normal macbook. after setting it up I messed with it a little to see what i could find (i used microsoft prior to this all my life; and im only 15). i was on it all that day, it started getting late so i decide to shut it down because i was sure i wasnt going to use it for a while. so about 3 days after i opened it i turn it back on, and to my surprice it made a wierd buzzing sound. i showed my dad and his thoery was that it could be like a fan or some other thing that spins inside. i ignored it, and now every time i turn it back on it does that. i have notice that it doesnt do it when i wake it up only when i boot it up. can anyone help me, please!!! i need to know if i got a deffective one so that i can take it back to apple.
BTW its a macbook pro 13" and it is the basic-off-the-self modle. i havent upgraded anything or opened it up.

The sound you're hearing may be the optical disk drive sort of 'whirring' at start-up. If that's what it is, that's perfectly normal - you're MacBook Pro is just 'checking' to see if there's a disc in the drive when it boots.
If you don't think that it's the typical optical drive 'whirring', then take your machine into your local Apple store or an AASP and have them diagnose the machine... but I'm thinking that what you're hearing is the optical drive.
Good luck,

Is it normal for the MacBook Pro to make noises when I put it to sleep?

I apologize for posting a new question so soon, but I wanted to get my technical problems with my MacBook Pro sorted out before I go back to school.
I'm worried about this one thing that happens when my MacBook Pro goes to sleep. After I close the laptop and it goes into "sleep mode" every few minutes or so it makes this noise like it keeps on turning on then going back to sleep, turning on then going back to sleep. It never did this before. Does anyone else hear these weird noises when it's in sleep mode?
For some reason it does not make these noises when I press the power button, and then press sleep. So this confuses me.

I have the same problem after just having my logic board replaced.

Is it normal for my MacBook Pro to reach 210 degrees?

During gaming my MacBook Pro will reach 210° F, without the fans audibly coming on... is this normal? It seems awfully high.

Some games will stress the CPU/GPU to such levels and higher. It may even come to the situation where the built in sensors will shut the MBP down before it destroys it self.
If your temperature monitoring device is not showing fan speeds, install iStat pro (download from the Internet) which will show fan speeds as well as the temperature. If at 210 f, the fans are not at 6200 rpm, then there may be a problem.
Ciao.

Does your mAh dropping and gaining normal for a Macbook Pro Retina Display?

I may seem like an over anxious new Macbook Pro user, but I have been keeping an eye on my mAh, just to track what my Max possible power storage is. To my surpise it has been dropping and gaining over the course of a few hours. I just want to know where it should be stabilizing at, and what factors could contribute to the increase and decrease, and if that is normal. The numbers range from: 8562 to 8708 mAh
Cheers

Yes, the fluctuation is normal - as your battery ages, the full charge capacity will diminish and it will fluctuate between chagres. Nothing to worry about - completely normal. My 15" late 2011 MBP, purchased this March, had an amperage in the 6890 range when I first got the machine. Now, after 163 cycles, it's down to 6810 mAH.
Perfectly normal - I could look again in a day and it will change again. Just what it takes to keep those ions on the move!

HT201177 Macbook Pro is turned on but the screen is black.

Ok, I have read A LOT of discussions on this issue but it seems like nothing works.
I bought my Macbook Pro 13" in September 2012 (so i've had it for a little over a year) in the States. So, I was just using the laptop a couple nights ago, then I closed the lid to the Sleep mode. Then, yesterday morning, I plugged in the charger and unplugged it after the batter's full (showed the green light). Later on that day in the afternoon, I opened the lid to wake up the laptop...but the SCREEN wouldn't display.... It has remained BLACK .... I KNOW the mac is still working..cuz when I turn it on the Caps Lock button shows green light and the sleeping light at the front is working...
I don't think it's RAM problem...cuz I did that Option-Comman-P-R thingy..and held it until I heard the third startup chime... (I held those keys at the SAME time...WAS I SUPPOSED TO press them one by one??)
Last method I used was the SAFE mode...and now the VOLUME buttons and the keyboard light buttons Dont work now.....
PLEASE HELP!!! THANK YOUUUU!!!

Please make a Genius Appointment and take it in for service.

MacBook Pro keeps shutting down when the screen is closed

Hi, I have a 2011 15inch MacBook Pro and it keeps shutting down rather than sleeping when I shut the screen. It also shuts down when left for short periods of time rather than sleeping. I have updated it yesterday and still the problem happens. I also installed a virus check to see if that was the problem and it didnt find anything it could fix! Any help is much appreciated!!!

Try a SMC reset. That may correct the situation.

I need to know the reason Why Macbook Pro Mid 2012 have yellow tint screen?

I am confusing about the reason Why Macbook Pro screen have yellow tint color?
There are few reason that I got from some apple shop saleman(In Thai) and someone in discussion experience.
First (1), The reason is IPS or PSL Technology made the screen to be yellow tint color.
Second (2), Someone told me, It is depend on production lot some lot don't have yellow tint screen but, some lot have yellow tint screen.
Third (3), Someone told me, It is normally case of Macbook Pro Mid 2012. Yellow tint screen will be recovering when using it long time.
(In the third, I'm not believe. Because, My iPhone 4s got a Yellow tint screen too. And, I used it for 7 months. The screen was the same at 7 month ago)
I need to know that what is true and what is false.
I just confuse Plz answer to me.
And, ...

Details of your specific hardware/software setup are in play, of course.
But, yes, that sounds normal.

I tried to update the latest software update for my MacBook pro (which was on 10/12) and after it started to update it restarted like normal but when it started back up it was running painfully slow and none oft programs will open.They all quit unexpectal

I tried to update the latest software update for my MacBook pro (which was on 10/12) and after it started to update it restarted like normal but when it started back up it was running painfully slow and none oft programs will open.They all quit unexpectedly. iTunes microsoft word all of them quit unexpectedly. Help!

Exact same problem with my 2010 MBP 2.4ghz 4gb ram 10.6.8. iTunes said update was needed, Software Update ran with various updates including a security update, truthfully didn't pay much attention, I always install the Apple updates. After the restart it took 3-4 times longer than normal to get to the login screen, same to get to the desktop but I'm familiar with that occurring on update restarts. Unfortunately it got worse from there. Performed a full shutdown and startup. Same long boot. After the desktop finally loads every mouse button press received a 2 minute beachball. I use menu-meters and both processors are under 10%. Waited a few minutes for disk utilities to launch, repair permissions estimates 3 hours for a typical <10 minute process. Activity monitor shows nothing over 10% CPU most of the time however ReportCrash pops to the top often. Any suggestions would be greatly appreciated. BTW zero problems until this update.

I've been using firefox for my macbook pro for the last three years but lately when it starts up, I hear a strange piano chord play. Have others experienced it?

Only recently has Firefox for my macbook pro been acting strange when starting up. I will hear a piano chord play only once when the tabs are loading. Over the past two-three weeks on daily usage, this has happened three times. I'm just concerned my macbook has a virus/bug or if this can be resolved with changing a preference/setting in Firefox. I don't believe this is a problem with my computer itself and I have checked the notification alert sounds and none are the piano chords I'm hearing. I am currently using two add-ons: Tabs-mix plus and FVD Speed Dial if that helps.

Does it happen when you start up in Safe Mode?
'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
'''If Firefox is open,''' you can restart in Firefox Safe Mode from the Help menu:
* Click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
'''If Firefox is not running,''' you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
;[[Image:SafeMode-Fx35]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
