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.

    May need the video circuit reworked and hope that the CPU isnt the cause as theyre Integrated on these models. (BGA Mount).. Big mistake as far as I'm concerned. Weve repaired a few of these..

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!

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.

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

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.

Close the lid, attach an external monitor, reopen lid.
Your display should now show on that monitr. If it is, your display on the MacBook Pro may be bad. I would try resetting the PRAM and the SMC before going to an Apple store. The SMC controls the MacBook's power founcts (see below)

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.

Macbook chip shim


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 ;)

When turning on my macbook pro


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.
