My ibook G4 won't start it shows black screen and loud fan sound only

my ibook G4 won't start, after you press the on key it makes a loud air sound, almost like a kernel panic sound, no screen light just the sound, it will turn off by pressing the on key again. Is there anything I can do to get it on?

Your very welcome.
You would need to apply pressure to the left side of the track pad about 2cm out. I found applying pressure to both sides of the track pad more successful. All you have to do is push down on the case, while making sure your iBook is on a flat surface. If you have someone willing to help you, you can get them to apply the pressure while you back up your files. Other methods would involve tempory repair or removal of the hard drive. If you remove the hard drive to be read by another computer, you would need a cady to put the drive into. These caddies are cheap enough. Would suggest you use a USB cady and plug your drive into that, which would act as USB external drive. I'd suggest you get a USB cady to remove your files, be careful to what operating system you have on the computer you are using to get the files off. Windows OS won't read a MAC OS X drive (extended journal format) It would need to be another Mac or a Linux PC.
If removing the hard drive is something your not to confident in doing, you could alway pay a computer repair shop to remove it for you. (Maybe they would have a USB cady for a 2.5 IDE hard )
Here is a link giving further details about this chip solder problem.

Here is an example of a USB cady

Let's hope just applying enough pressure is enough to get your files back up.
Best of luck!

HP Pavilion Entertainment won't start just shows blue screen

HP Pavilion Entertainment won't start just shows blue screen. Sometimes says missing operating system after changing boot order. I have seen error message 303. This happened after I couldn't stop coolncheap popups so I saved everything to another computer and did a complete restore. When I was in the process of getting it back to working order I allowed updates recommended and optional and then everything started.

Also pressing F11 won't take me to recovery

N97 camera won't start(just a black screen)

My N97 camera won't start just a black screen this issue since the update to the new firmware

ooooooooops so sorry about this, here it goes and start with the first code.
With all these operations I recommend you TAKE OUT MEMORY CARD and DO A BACK UP OF YOUR STUFF!!!
1. *#7780# - Restore factory settings - resets all the settings to the default ( you will not lose any data)
Make sure you back up your data as you will lose all of it when you perform option 2 or 3 on this list. The default code for ALL operations listed here is 12345
2. *#7370# - Reformat your phone (out of the box, tho keep in mind that most newer nokia phones at least n series, e series and s60 based phones have udp - user data preservation so not ALL data may be lost. still it is a good idea to always do a back up of your stuff.)
3. This you perform as a last resort. Nothing else is working.If the phone is not showing any activity, proceed with hard formatting , turn off your phone, hold the following buttons while pressing the power button. (the default code is 12345)
hard reset - hold the following buttons *, 3 (number button) and talk/green key. turn on the phone and do not release those buttons until you see the Nokia boot up screen. once you feel the phone power up you can let go off the power button while still holding all three buttons ( for Nokia 5800XM - use the following buttons to do a hard reset, GREEN/RED/CAMERA keys pressed all at once on power up. this will only work on 5800's that have firmware version 20... and up. ) For Nokia N97 (unofficial version but works) is SHIFT /SPACE BAR / BACKSPACE while holding the power button. Again do not let go until you see the handshake screen.
If these codes are not working the only thing for you to do is contact your Nokia Care Center/Service for assistance.
You know what I love about you the most, the fact that you are not me ! In love with technology and all that it can offer. Join me in discovery....

Macbook Air starts with a white screen and permanent "poing"-sound...

Macbook Air starts with a white screen and permanent "poing"-sound...
Tried SMU, PRAM, MMU resets, but nothing helps...
Thank you for your support.

You need to take it in for service, it may be a stuck key or component failure.

PopcornTime starts with a black screen and does not load

I installed PopcornTime from the AUR and it does not seem to load. When I launch the application, it simply loads a black screen and does not move from there. When I launch the application from the terminal, I get this output.

It seems as though quite a few files are missing, though the yaourt built the application just fine.

I had the same issue with the git version. Install the stable version and it should work fine

Try booting from your install DVD. What happens then? Can you see anything?

Imac starts with a black screen and flashing white light on console

I have a 24" imac, it is white and it is from the first year they used the intel chip. When I power it up I get a black blank screen and then the white light on the lower right side of the console flashes on and off. I hear the disk drive spin (I put the 10.4 install disk in ) and it does nothing. How do I get the disk out. I even tried holding down the mouse button at start up and that doesn't work.
I tried to remedy this myself by resetting pram. I have taken out memory and put it back in. I have been able to get it running twice before by taking out memory and putting it back in but it only worked for a little while and then I turned it off and went to turn it back on and same problem again. Is this a logic board problem or something else. I think I read if it was the logic board the disk drive wouldn't work but I hear it spinning.
Can anyone help me?

Hi MacGruff69
That has all the classic signs of unseated, improperly seated or bad RAM.
Laying the iMac face down on a soft towel and reseat the module(s) by pressing real hard on each one with both thumbs, then closing the ejector clips and replacing the cover.
http://support.apple.com/kb/HT1432
Them if the iMac still has the same symptoms, try one module at a time or replace the module(s) with new one(s).

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

Mozila crashed suddenly and now it won't start. it shows white screen only. It won't let me reinstal it, sys shows that every .exe file is corruped.

I was listeninig songs on youtube and mozila and whole sys just crushed. I recovered sys but after that mozila won't work. It lifts up just mozila frame and it just won't work. It won't let me reinstall it too. I downloaded about 10 instalations and for every it gaves me notification that file is corruped.
I didnt uninstal it for not to lose all the bukmarks.
Help me, what to do.

Try this. It worked for a few users after a drop.
Turn the iPad over and give it a very HARD slap on the back. May take several slaps.

IBook g4 stuck on start up with gray screen and circle that looks like its downloading

iBook G4 stuck on gray startup screen with circle like it's downloading

If your iBook G4 portable running OS X 10.5.8 or 10.4+
shows a grey screen on startup or other similar variant
to the failure to fully start, there are a few good Support
articles from Apple Support site online that may help.
Each has information to read through, consider, & try.
•Mac OS X: Grey screen appears during startup...
http://support.apple.com/kb/ts2570
•Resolve startup issues & perform disk maintenance with Disk Utility and fsck
http://support.apple.com/kb/ts1417
This is akin to troubleshooting since you have a measure
of trial-and-error to resolve the problem; & at times there
may be more than one thing to do, &/or more than once.
Hopefully this helps.
Good luck & happy computing!

Satellite U400-10N fails to start while showing black screen!

So i press the power button, The 3 Leds are appearing fuctional but the CPU-GPU fan fails to start!
After a while it shuts off it self and then it tries to start again but the fan fails again while only the power led is on and not the others (Led 1 and 2 on the bottom).
Must say again that the screen appear always black (might be dead also)
I thought it was an overheating problem so i cleaned up the fan but with not many signs of dust!
But that was crearly not the problem because i tested it!
Now i think it might be a GPU problem but i dunno for sure!
Any suggestions what it might be and how o fix this? Thank you!

Hi
It can be RAM problem, it can be an motherboard problem, it can be also an CPU or GPU problem.
Any part can be affected.
So what to do?
You could check part like RAM. You could purchase new, good tested RAMs and could replace it but what happens if you purchase new RAM modules, replace it and notebook would NOT power up?
You would spend some money for new RAM but finally other part could be faulty
Therefore I think an professional service technician should check the unit firstly.
The guys could give you a proper answer about the faulty part and then you could decide what to do
You know what I mean?

Mac Pro (2009) won't start, no chime, black screen

Hi,
I am having a problem with my 2009 Mac Pro. It fails to boot. There is no chime and the screen wont turn on;stays black. It wont boot off of the system dvd and I even tried installing an HD that has a good version of the the OS on it. I also tried booting from the DVD with no installed drives to rule out one of the internal drives doing someothing funky. Nothing happens at all, the HD or DVD will spin for a moment and then all is dead.
Any suggestions? Thanks in advance.

or this one:
Troubleshooting: My computer won't turn on
If no joy, remove anything and everything that may be dragging down the power, in hopes of getting a chime. This includes graphics card, any other PCI cards, all drives, and some say all but a minimal amount of memory. Look for the chime.
If you get the chime, you can build slowly up from there. Add back graphics card and keep going. Add back memory and keep going. Add back DVD reader and boot from Installer/Utilities DVD or run the Apple Hardware Test. And so on.

Won't start no chime black screen.

Husband used computer last night. Battery died he plugged in turned it on did what he had to do. (working fine)
Went to shut down and failed to wait for it completely before he closed the cover. Now it will not boot.
Acts like it's in sleep mode. Nothing I've tried works. Any suggestions? Sleep light very light when cover open
bright light when it closes. Tried to hard boot, reset, et al.

Tried Multiple times this morning. Let it rest all day, just tried multiple times again to no avail.
Took out battery held down power 5-10 seconds replaced battery and power cord, still nothing.
Cannot do any commands while booting up.

MacBook Pro won't boot - stays on black screen and beeps every few seconds

Hi,
My MacBook Pro has been having issues - when powered on wont boot past the white screen and more recently will just stay on black screen and beeps every 5 seconds. I had someone look at it and it seems apparently the motherboard is the problem
and either needs fixing or replacing. As I am traveling in Nicaragua the closest apple store is in Managua (capital). Would I be able to get the motherboard looked at and replaced if need be at this apple store? Also, does anyone know the approximate price for the motherboard to be replaced? Up until a few days ago the laptop was still turning on and working every now and then but now stays on black screen and beeps.
Any advice would be very helpful!
Thanks

Welcome to Apple Support Communities
It means that your Mac's memory is damaged > http://support.apple.com/kb/HT2538?viewlocale=en_US&locale=en_US
First, replace the memory modules. You can buy more memory at OWC or Crucial. It can also be replace by a reseller.
If it doesn't work, the RAM slots are damaged, so your logic board has to be replaced. It costs more than a half of the price of your MacBook
