Question about Apple MacBook Pro Laptop Computer with Intel Duo Core 15.4 Inch PC Notebook

When turning on my macbook pro

The screen does not open up (all black) and all i hear is the fan shishing thru the speakers.

After my macbook pro has been closed for a short time and then I open it up, the screen is black and all I can hear is the fan going. When I turn on power button, I hear fan start and a slight sound from Cd drive but then it sits with power light on in front but no OSx symbol, no key response only the fan.

Hi

Try and reset your PRAM and VRAM here is some infor for you.

Summary This document explains how to reset the parameter random access memory (PRAM) and nonvolatile RAM (NVRAM) on Macintosh computers.
Important: If your computer does not retain parameter RAM (PRAM) settings when it is turned off, this generally indicates that the battery needs to be changed. Refer to Macintosh Family: Batteries and Part Numbers.
Products Affected Portable Computers, Desktop Computers
Resetting PRAM and NVRAM

  1. Shut down the computer.
  2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
  3. Turn on the computer.
  4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
  5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
  6. Release the keys.
Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.
Resetting PMU on PowerBook or iBook computers In some troubleshooting situations, if resetting PRAM does not resolve an issue, resetting the PMU may be the next appropriate step. For information on when this is appropriate and for instructions on how to reset the PMU in your PowerBook computer, see Resetting PowerBook and iBook Power Management Unit (PMU).
Additional Information Resetting NVRAM in Open Firmware If your computer is Open Firmware-based and you are unable to reset NVRAM as described above, you may alternatively reset the NVRAM and Open Firmware settings using the steps in the Solution section of Message “To continue booting, type 'mac-boot' and press return”.
Contents of PRAM Some Macintosh computers may not have all the settings described below. For Mac OS X information, refer to Mac OS X: What's Stored in PRAM?
  • Status of AppleTalk
  • Serial Port Configuration and Port definition
  • Alarm clock setting
  • Application font
  • Serial printer location
  • Autokey rate
  • Autokey delay
  • Speaker volume
  • Attention (beep) sound
  • Double-click time
  • Caret blink time (insertion point rate)
  • Mouse scaling (mouse speed)
  • Startup disk
  • Menu blink count
  • Monitor depth
  • 32-bit addressing
  • Virtual memory
  • RAM disk
  • Disk cache

hi wa_flyboy,

I suggest you first do a test to determine if it is your macbook's screen or graphics processor which is at fault. To do this you need to connect an external display to your macbook.

The macbook has a mini-DVI port for connection to external displays. Depending on the connector of the external display you use to do the test, you are either going to need a mini-DVI to DVI adapter (for a DVI display) or a mini-DVI to VGA adapter (for a VGA display). These adapters are sold separately by Apple, see http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?nnmm=browse&mco=669DFFE0&node=home/shop_mac/mac_accessories/displays

If an image is displayed on the external display after you have connected it to your macbook, you know that the screen of your macbook is faulty. In this case it would be an economical option to take the macbook to a repair shop where a technician can determine the faulty component (either one of the following display components of a TFT LCD screen can fail over time; the inverter, the backlight or the cabling). These can be replaced under warranty or they can order new ones if the warranty has expired.

If the external display shows the same symptoms as your macbook's display, it is the macbook's graphics processor which is at fault. I'm sorry to inform you that I think this is the cause of your macbook's display problem. Replacing the graphics processor of your macbook entails replacing the motherboard.
If the macbook is still under warranty I suggest you replace it and let technicians migrate your data from your current macbook's hard disk to your new one.
If the warranty of your macbook has expired, it's a more economical option to buy a new one and migrate your data to the new macbook. This will only cost a few dollars more than the cost of replacing the faulty motherboard (including the service costs of the repair shop to which you take your macbook), but is still more economical seeing as how you get a new machine which has a full warranty.

I hope this is helpful information and thanks for using the FixYa services
Kind Regards

SOURCE: MacBook won't start up.

If you have your Mac OS X Install disc, insert it into the drive.
Restart the computer and hold down "C" while booting.
Choose your language.
Select "Disk Utility" from the "Utilities" in the menu bar.
Select your Macbook's hard drive in the left sidebar.
Click the "First Aid" tab thats along the top of the viewer window.
Click "Verify Disk" (not verify disk permissions)
If this shows errors click "Repair Disk"
Once completed close the Disk Utility window.
Restart the computer.
If this fails to fix it as well then your next option would most likely be recovering your files from the macbook either by booting into target disk mode (hold down T at startup) and transferring them via a firewire cable, or removing the hard drive and hooking it up to another Mac to get the files. Then do a clean install of Mac OS X using your installation discs.

Am I always supposed to hear the fan of my computer?


Hi AriEl,
No, the MBP's fan should not be a loud sound.
The fans on my regular MacBooks do make an audible sound, but it's a low 'white noise' king of thing that I don't really notice unless there is no other noise in the room, or if I make myself aware of it.
You can try blowing compressed air into the vents at the back of the laptops bottom piece. That sometimes helps by getting rid of excess dust in the fan blades & vents.
If it doesn't help, you might need to take the MacBook to an Apple Store or other Apple certified repair shop.
Hope this helps you!

Resetting the PRAM may do the trick:
You reset the PRAM by rebooting a Mac and then immediately hold down the Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won't work.

you've tried rebooting, you've reset the PRAM, you've done it all, but your Mac is still behaving strangely. What next? In certain circumstances, resetting your Mac's System Management Controller (SMC) can be a solution. This is sometimes necessary to restore normal lower level system functionality to your Mac.

Here's how to reset the SMC on any type of Mac (and any version of OS X) and the type of problems that it may resolve.
When & Why Reset SMC on a Mac? Some Common Hardware Reasons

Typically it's power and hardware related issues that can be helped or resolved by resetting a Mac SMC, particularly if you're having these types of problems:

* Issues with your Mac's cooling fans and fan management: fans run constantly at high speed, fans run high despite low CPU usage and adequate ventilation, fans not working at all, etc

* Power management and battery problems: Mac isn't turning on, sleep isn't working, random shutdowns and reboots, battery isn't charging, Mac won't wake from sleep etc

* Light problems and improper lighting management: battery indicator lights aren't working, display backlighting isn't adjusting to ambient light changes, keyboard backlights not working, etc

* Video and external displays not working: display brightness functionality not working properly, target video mode isn't working properly, external display isn't working, etc

* General performance and functionality problems: abnormally sluggish behavior despite no CPU or disk usage, external ports not working, airport & bluetooth aren't showing up, external devices are not being found, etc

So now that you've concluded you need to reset your SMC (Note that the SMC is on Intel Mac's only), here's how to do it on MacBook's, MacBook Pro's, iMac's, Mac Mini's, and Mac Pro's. Notice that the reset instructions are different for MacBook and MacBook Pro's if you have an internal or detachable battery.
Reset SMC of a MacBook Air, MacBook Pro Retina, or MacBook Pro's with an internal non-removable battery

This is how to reset SMC on most modern Mac laptops:

Shutdown your MacBook Air / MacBook Pro
Connect the power adapter to your Mac
On the MacBook/Pro's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Boot your Mac as usual

Here's the key sequence to hold down:

Reset the SMC of a MacBook Air or Retina MacBook Pro

Do keep in mind that by resetting the SMC you will lose power specific settings, like the time it takes to sleep a Mac and other customizations to power settings. No big deal, but if you have made many changes to your hardware behavior you will want to adjust stuff like sleep behavior again.
Reset SMC of an iMac, Mac Pro, Mac Mini

Resetting SMC is different for non-portable Macs:

Shut down your Mac
Disconnect the power cord
Press and hold the Mac's power button for 5 seconds
Release the button
Reattach the power cables and boot the Mac as usual

Reset the SMC of a MacBook or MacBook Pro's with detachable batteries

mac reset the smc Older MacBook laptops with a removable battery can reset SMC with the following approach:

Shutdown the MacBook/Pro and remove the battery
Disconnect the power adapter, hold the Power Key for 10 seconds
Release the power key and reconnect your battery and power adapter
Turn your Mac on
Let boot as usual

Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.

Happy New Year,

My macbook pro wont start and i can hear the noise of the starup but the screen is black


Connect to external monitor to isolate the problem. If you get a picture on external monitor, then you know your screen is fu.k.d up. Since its a MacBook Pro, it might still be under the 1 year warranty, so take it to the Apple store and have them deal with it. If you get no picture on the external monitor, then you know you got a problem with the computer.

Hello,
Thias can also come from a dead hard drive, or a dead backlight (screen).
The best test would be to plug an external monitor to see if something shows up. If yes, that would mean that the backlight doesn't work anymore. If not, then you have an other hardware problem (motherboard, hard drive).
You can check if the hard disk is the problem by removing it. You should then see a flashing question mark and the screen on.
Keep in touch ;)

Does it work with an external?

1) If it does boot through external. Your LCD, LCD inverter, or LCD cable may need replacement.

2) If it does not boot, then it may be problems with video card or motherboard problem. May need motherboard replacement.

Please let me know the follow ups of it. Thanks!

About the only thing you could try is to remove one each of the ram sticks in the machine and try them one at a time.

here is a link to the apple PDF file about it (you need acrobat reader or foxit PDF reader.

http://manuals.info.apple.com/en/MacPro_MemoryDIMM_DIY.pdf

If that doesnt do it then check and see if you have Applecare warranty still and take it in for service.
