Hit Power On, hear faint clicks, screen stays black. Dead HD?

My son's MacBook won't start up. When I turn it on, I can barely hear some faint clicks spaced about 1 or 2 seconds apart and the screen stays off.
What are the chances this is a bad HD?
Also, I've got a MBP and both my machine and my son's MB take serial ATA hd's. If I erase and reformat my MBP HD, I should be able to put it in his MB so he can use this as his HD, correct? (The reason I ask this is that I've wanted a faster and larger HD for my MBP. This may give me the reason to go out and get it.)

Doesn't sound very good. I would expect to see the screen turn on with a flashing question mark or something. Even if the hard drive is dead, you should be able to boot from an installer DVD. My money is on the power supply.

HT201177 When I turn my computer on, I can hear it starting up but the screen stays black. Anyone know how to fix this?

When I start up my compute, I can hear it starting up but the screen stays black. Has anyone else had this problem and found a fix?

If you press the caps lock key does it light up? If it does then this indicates that your system is booting but the display is either not recognized, is not displaying any video, or the display is displaying video but the backlight system is not lighting up. As long as you've tried turning up the brightness then there is not much you can do other than take it in for a diagnosis. If you have a very bright flashlight you can turn on the iMac and then shine the flashlight onto various areas of the iMac display to see if you can see any faint images on the display. If you do then this indicates that the display is displaying the image, but the backlight is not turning on for some reason. It doesn't change the outcome, but at least you can assist the technician who is troubleshooting your iMac.
Please let us know what you find out.

Try a #1 SMC Reset and see the Apple links, if that doesn't work make a appointment for a evaluation.

Imac G5 20" makes startup sound, and fan kicks in, but screen stays black

Hello. I have read the many similar postings and tried alot of ideas with no luck. Here are the specs on the model:
G5 20"/2.0/512mb/250gb/Super/56k/BT/AP EMC2056 Model A1076
When you push the power button, you get the bootup sound, and the fan turns on. Then 30 seconds later, the fan goes into hyperdrive. The whole time the screen stays black. I have tried resetting the pram, get no sound then. I have tried the internal startup button below the fan housing, and it does NOT have the 2nd button there as it is an ambient light model. So I held the power button and plugged in the power cord, still nothing. When plugged in, the 1st green light lights up on logic board. When I hit the power, the 2nd green light lights up. I have tried an external monitor with the adapter plug and still no picture. I do not even hear the hardrive try to read. Could it be a power supply? What are the other 2 lights on the logic board for, as there are a total of 4? I have not tried to boot from a cd or change the battery yet. I don't know if there is a point in doing that, as the screen remains black. I cannot use a conventional pc power supply tester either. Any other ideas on this situation?

"Could it be a power supply?"
More than likely if everything else possible has been ruled out. Your model G5 had an extension repair program which has long expired for your exact issue. Shame you missed it.
"I have not tried to boot from a cd or change the battery yet. I don't know if there is a point in doing that, as the screen remains black."
You won't know if it will do any good until you at least give it try. You should also run Apple's Hardware Test from the Install DVD #1. The DVD label will tell you which key to boot up from to run the AHT.

Satellite A200 screen stays black when trying to boot

Hello everyone,
My Toshiba Satellite A200 notebook is not working anymore, so everything started when I was playing a game, suddenly, the screen turned blue with some tiny text written on it. I had to hold the power button a few seconds to close it because nothing was happening on the computer. I then pressed the power button to open it. Everthing was going well, until the welcome screen. At this part, it was written "Welcome" but the Vista loading circle left of it wasn't turning.
After a few seconds, I decided to close the computer again, so I did hold the power button so the computer closed. Here is the problem : I tried to reopen it, but the screen stayed black. Nothing was happening. The power light was blue, but not any computer activity. So I let it like that a few minutes then closed it and tried again, but the same thing happened. I tried to disassemble it and noticed one of the two memory card wasn't fully in its slot. I fixed it, but it didn't fix the problem.
I also tried to plug another screen on it, but that one was also black. So I put back the screen on its computer and tried to boot my laptop and it worked. It was booting, but the first problem came back, the Welcome screen was frooze there. So yes I did close it again and then the same thing happened, the screen stayed black.
I don't think the problem is the screen because as I said sometime it goes to the welcome screen. Also I don't hear any welcome sound when the screen stays black as if the computer would simply not start up. And as I said earlier, I don't see any computer activity on the little light in front of the computer. And left of this one, I clearly see that the computer is ON because the power light is blue.
So this is my problem, next time the computer manages to start up I'll try to boot it on the SAFE MODE, but until then, I don't know what to do. Please, help me.
Thanks in advance,
MrRoy
EDIT :
After letting the computer turned off for about 30 minutes, I started it, and booted in safe mode. At this step, I securely closed my comptuer with the shut down button instead on holding the power button. Then I reopened my computer, and it booted and the problem was fixed. Now my notebook is openened and working.
So if this is happening to you :
1. Shut down you computer.
2. Wait for about 30 minutes.
3. Boot in safe mode
4. Shut it down using the shut down button istead off holding the power button.
That should work.

Finally, it doesn't work. I don't know why but my computer did start up after the 30 minutes, but now it's not working anymore. It just won't startup like I said later, with a black screen.
The computer did work for about half an hour. I mean, I managed to start it up but after executing a program, it just froze and I had to hold the power button to restart it. I did it about 3 or 4 times, then it simply did the black screen again. I think the problem is my processor, maybe it's damaged or something, could it be possible?
Because I see that the processor isn't working when I try to start it up.
So let's say it's damaged, would that be the symptoms of my computer?
And if it's the processor, the only way to fix it is to send it to a reparator or something, because I don't feel like it, I'd rather do it myself.
But right now, my computer is simply not booting, like I said in my previous post.
Thanks in advance,
MrRoy

HT201263 Iphone4 screen stays black after configuration

Iphone4 failed to respond during normal usage. Therefore I turned off the Iphone4 and restarted the device. Unfortunately the screen of the Iphone stayed black after seeing the apple logo.
As the above didn't resolve the issue, I restarted the Iphone by holding the home and power button. The apple logo appeared again and than the screen stayed black. Although the i-phone is making sounds and you can switch between normal and silend mode.
Than I rebooted the I-phone by using Itunes, and reinstalled a backup, also the screen stayed black after the backup. Although in the beginning you can see the adapter and I tunes logo on the Iphone screen.
Than I rebooted by using Itunes and set up as a new device. I can see the following screen:
After swiping the screens turns black although when I touch the screen I can hear the phone is still working.
How can I resolve this issue?

Call of Duty puts a heavy processing load on several internal components that may be causing them to overheat. I would suggest that you download and install the Free and highly recommended "iStatPro" utility and post the temperature readings that it gives you, around the time that the time that the display goes blank, here in this Forum. (Play the game for quite a while and then check your temps in iStatPro.) That may give us the data we need to diagnose your problem.

I have a HP Touchsmart 300-1020 that powers up but the screen stays black. help!

I've been experiencing problems intermittently after shutting my TouchSmart 300 PC down. For the past few days when trying to turn it on ; the screen stayed black! I could hear the fan start rapid then slow down, I can see the green internal light blinking inside and lights on the outside of the computer but still nothing on the screen! I've tried plugging it into different outlets around the house was successful with one, but then, came the error message;
Page fault in nonpaged area. Today I tried to turn it on and I got the same thing described above. The computer's operating system is Windows 7 64-bit, purchased Feb. of last year and is refurbished.

Hi
You have a couple of options as I see it please run the Hard drive and Memory test check if both off then passes if any fails then you need to replace the part. If test passes you could try The F11 option to do system restore Or to do a recovery on the unit before doing recovery kindly back up data as it will be lost web link given below this will help you to let you know how to do the steps.

Screen stays black on start up

This is my second Toshiba laptop to do this to me. I just got this one in 2013. The last one was a no go on fixing it cuz it was cheaper to replace it. Tonight i come home and the same issue. The screen stays black. I can hear it running but have no lights except the white one in front showing its plugged in. Any help will be appreciated. Getting disappointed in this brand.

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a

Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

How do i fix my iod touch... screen stays black

how do i fix my iod touch..... the screen stays black with the apple logo then cuts off again after like 5 minutes..... someone please help me ?

Please tell me it's not jailbroken. If it is, all bets are off. It is not...
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

IMac starts with fan, screen stays black

When attempting to start my iMac G5 (Ambient Light Sensor), fans come on but screen stays black. A couple minutes later, the fans rev up and run very quickly and loudly. This started happening when:
1. One day the screen showed a green question mark with a message indicating that the computer needed to be restarted in a box
2. Green lines were all across the screen
3. I forced it to shut down by holding down the power button
4. When I attempted to start it back up the fans started but the screen stayed black
5. After a couple of minutes, the fans revved up
This has been happening ever since. One time the computer started to the desktop but everything was frozen. I have reset the PMU, checked the diagnostic LEDs, reset the PRAM-basically everything suggested. Can anyone help? Thanks!

Try the suggestions mentioned in the following Articles:

Strongly recommend that you update to OS 10.4.11. Your system info confirms you are still using the basic Tiger OS.

What is wrong with the screen stays black

what is wrong with the iPod if the screen stays black and won't turn on, but is fully charged.

Could be one of the two:
1. Device sleep - Press and hold power button for six seconds and see if that wakes up the unit
2. Device freeze - press and hold the power and home button for few seconds till Apple logo is seen.
Hope this helps!

Imac G4 15" Screen Stays Black After Screen Saver Goes To Sleep

I have an imac G4 15" that I just got from a friend that works pretty well, except that after it goes from the screen saver into to sleep mode, the screen stays black. I can hear the error chimes when I try to awaken the screen with the keys, but the screen just stays black. I have tried to increase the brightness, etc. but to no avail. Eventually I have to resort to re-booting and I am afraid that at some point, either the computer won't reboot or one of my external hard drives will crash. Any advice from someone who has experience with this issue would be greatly appreciated.
THANKS!
