When I start up my macbook, the screen flashes, and then goes blank. I can hear my hard drive and my fan starting to spool up, what's going on??? is it something I can take care of myself? Thanks everyone

    Mine does the same thing but if I turn it upside down and/or kind of twist the body(Sometimes it takes both, actually most times it takes both)  it will start up, it sounds like the motor is hitting or binding and stopping inside, and stops then tries again, and again. If I very slightly twist the body, this seems to free up the motor and then it will start. Sometimes it will shut back off until it gets good and warm, then I usually don't have anymore problems until the next start up. If my screen goes black at start up I have to hold down the power button and start all over. Is this the same problem? It seems like just a loose connection inside .

If these options fail and Apple does not cover you we can generally rework the video circuit on these. Weve seen quite a few with characteristics and failures similar or Identical to Most other Intel based Laptops.

(IE: HP's, Dells, Sonys, Toshibas)..

Good luck!

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

  1. Verify startup process passes initial memory checks and POST (Power On Self-Test) with no beeping sounds or flashing sleep LED. Check video activity.
  2. Disconnect any peripherals and Ethernet cable.
  3. Reset SMC using the procedure for your computer.
  4. Reset PRAM by holding down Command-Option-P-R keys while restarting, until you hear the startup sound for the second time.
  5. Start up from known-good original system media or an up-to-date, bootable Mac OS X volume.
  6. Run Disk Utility or check Mac Resource Inspector (MRI) results to verify SMART status of the your hard drive.

Can not get the Operating system to Start, Grey Screen at Startup


Sound like your motherboard is going bad. ibook G4's are notorious for this. The only thing you can do is either replace the ailing motherboard or try to find the breaks on the existing board. I am going to try and bake a board and see if that repairs any SMD *(surface mounted device) breaks.
I will keep you posted!

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.

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 ;)

Hard drive failure


www.drivesavers.com
www.ontrack.com

You can contact this companies regarding data recovery. The "Genius" was wrong about the drive being retuned to Apple, that will only occur if you have a system under warranty, and you would be returning it to Apple to avoid being charged.

As far as replacement hard drive going for $325, that too is pretty steep, see this link:

Random Flashes on Macbook 13" native screen


you could try reseting the pram. this is accomplished by holding down Command, Option, P, and R at startup you will want to hear the start up tones at least three times. if that doesnt work you might have an inverter issue, the inverter is located behind the screen and needs to be looked at by a pro

Acer Aspire 5100 will not start right


It seems your hard drive has corupted.
This sucks, all you have to do is push ALT F10 and then go through the reseting menu, you will loose everything on there though except the original data.
