Ibook will not turn on, please help. ASAP

I have an i book laptop but i am not sure what model it is. I just know that it is about 4 to 5 years old. I used to have some one that could fix it for me and tell me what is wrong. But i do not have them any more. My computer will not turn on. Even when i plug the power block into it. I have looked at the mac support things. but none of them have helped me. if some one out there could help me i would be sooooooo great full. Please some one try to help me solve this problem. i have tried the (PMU) restet, when you press shift, ctrl, option simultaneously. Then you are supposed to wait 5 seconds then turn it on. that did not work. For many months now i have been struggling with this problem. i really need some help, because the mac support on this website has not been helping me. So maybe by creating this account, and writing this letter. Some one will come to help me.
By the way i cant even find out what OS it is because i cant turn it on to find its information

Thanks - but I can't see anything, the screen is dead (which is why I put the disk in - I was following the troubleshooting instructions), all I hear is the fan, but there's no screen prompt. I've tried resetting the PMU and the PRAM without success -- I've been having this problem on and off for a few weeks but it usually started ok the second or third time. Now, however, it's not working at all.
Hi,
You may be able to eject the CD by starting in open
firmware.
Hold down the command-option-o-f keys as you start.
When you see some text on the screen release them. At
the prompt type "eject cd" (without the quotes) and
press return. It should eject after a few seconds.
Next try resetting the NVRAM. At the prompt type:
reset-nvram <return>
set-defaults <return>
reset-all <return>
It should restart after the third command is
entered.

BlackBerry Torch 9800 Will NOT turn on PLEASE HELP

My phone went black today and will not turn back on.. I have taken out the battery and the sim card, when i put them back in the red light at the top just flashes and nothing comes on the screen. I have tried to boot it by charging it and hooking it up to the computer. The BlackBerry desktop manager says it can not connect to the phone. PLEASE HELP

I have had the same problem 3 times over the past 2 years. The first time, Telus replaced the phone immediately as I was told it was a factory defect. The second time happened within the warranty period and TELUS decided to send it to BlackBerry to get it repaired. Phone came back,4 weeks later and worked properly but within a month same issue, does not boot up. Third time and three weeks later a new Torch came back from BlackBerry w on what was wrong with that phone. Now I am staring at the same problem on the THIRD TORCH I HAVE HAD IN TWO YEARS!!! What kind of defective product is BlackBerry shoving down our throats. As consumers we should expect what we purchase to work and not have to waste 4 hours reloading this and uploading that. Frankly I don't want to find the time to upload a bootfile that is missing, WHY IS IT MISSINg? Why is there a problem in the first place with the phone. If there is a defect, own up to it and recall them. I have had BlackBerries for the last 10years, this one is going into Lake Ontario and I am buying a an ANDROID. Its funny how even the sales people at the corporate TELUS Store and the tech support atff on the phones told me to just chuck it and never buy another BlackBerry again because they are also sick and tired of letting their customers down.
Is this a 9800 you're talking about? Reading your post, this is actually the 4th time that you've had this happen, with 3 different phones, correct?
When you talk about "reloading this and uploading that", are you talking about reloading the OS, or applications? I'm wondering if there's a particular application you're loading that's causing it.
While I'm sure there are faulty 9800s out there, and I've had a few myself (among 80 users), I find it hard to believe that you could end up with three faulty ones in a row. Are you able to get the battery charged somewhere, just to be sure it's not just a dead flat battery? It might be that you've got an application that's flattening your battery to the point where the phone can't start, even on the charger.

My ipod will not turn off please help???

Everything works on my ipod, but it will not turn off. It will play and pause but not turn off.

I too have had this problem. In fact it seems to be a fairly common problem, suggesting that it is an unaddressed bug.
Here's what you can try:
1. Reset your iPod by holding down the Menu and Select buttons simultaneously for 5-10 seconds. After your iPod reboots, see if it will turn off. If not:
2. Restore your iPod using iPod Updater, which you can download from http://www.apple.com/ipod/download/ . Restoring your iPod will delete all songs, pictures etc and reload the iPod's operating system. If that doesn't fix it, you can:
3. Try a work-around. Can you turn it off using the Sleep menu option? If you don't see that in the main iPod menu, go to Settings/Main Menu and turn on the Sleep menu option. This didn't work for me, but others have een able to turn their Nanos off this way.
If none of these things work, your only option is to have Apple replace you iPod. You can do this by contacting Apple support, or by going to the Genius Bar at an Apple retail store.
Several people (including me) have seen the not-turning-off problem in conjunction with the Nano frequently showing a message saying that firewire connections are not supported. In my case my Nano became unusable because the firewire message would pop up so often that I couldn't navigate through the menus to get it to play anything. I took my Nano to an Apple store and the Genius Bar guy replaced it on the spot. Unfortunately the replacement also doesn't work (headphone jack doesn't work so I can't hear any music) so I will have to go back again, but don't let my run of bad luck prevent you from getting a replacement.

3 beeps after ram upgrade, computer will not turn on, please help! I have tried everything.

I have a late 2011 Macbook Pro 15 inches, i recently upgraded the RAM from Crucial 8gb (4gbx2) to Crucial 16gb (8gbx2). I have done thies before, was er careful, and had antistatic clip, clean work surface, etc. When trying to turn the computer on again, i hear 3 slow beeps, repeated three different times, and the computer does not turn on. I have been looking around for solutions.
I have already swapped the memory modules, cleaned them, dusted the whole computer with air can, put the old ram in and still have the 3 beep problem. It no longer works even with the old ram. The computer was working perfectly fine before this.
Am i missin a step? I saw in a video on youtube that i have to reset the RAM with Alt+P+R+Power button, but nothing happens.
Please help, i am self employed and my Mac Book Pro is the computer i work with!
I have Lion operating system, everything updated very recently. Stock 512 gb hard drive.

Thanks for the quick reply Allan, i have reseated the ram 4 times, swapping top and bottom Ram modules, and pushing them in firmly and pressing down evenly with both hands.
I tried to put the old ram in as well in case the New RAM was bad, and that did not work anymore either. I am from Mexico and live in Mexico City, and it is not easy to send the RAM back and get an exchange. I will go to a MAC repair center on monday, but think i am missing some simple step somewhere. As i said this is my work computer and i really need it!
I have reread what i wrote before, to clarify my computer was working fine with the old 8 gigs of ram, i just wanted it to be faster, and bought 16 gb since they are now much cheaper than a few years ago.

IPod Touch Will Not Turn On - Please Help!!!

Hi...I have a 1st generation touch. I used it last week and it had a low charge. When I tried to charge it this morning nothing happened. The computer or iTunes would not recognize the touch. I remembered updating iTunes the other day...so I did an uninstall and then reinstalled...wondering if that was the issue. That did nothing. I've tried to go into recovery/DFU mode...and nothing...no response at all. Unfortunately my touch is out of the two year warranty. The touch has never been jailbroken. Does anyone have any suggestions on how I can save my touch?
Please...any help would be appreciated.
Thanks.

having the following problem...
my ipod touch was hot at the bottom rear when i picked it up. for no reason. the display worked ok but didnt let me slide to unlock or slide to switch off. i have since fully charged it, fully discharged it several times and the screen remains black no matter which buttons i press. i have tried the reset by pressing top and bottom button for 10 seconds still nothing happening. It is now not recognised by the computer when i switch it on. or the tone from the computer when the usb is connected. iv not dropped or damaged the ipod in any way. tried chaarging via ac plug for iphone and via laptop.
just there tonight i tried charging via a different usb port on the laptop and that has brought it back to life. started charging again etc but the screen has what looks like a watermark across the right hand side making the touchscreen function at that side difficult to use. hopefully this will help.

My ipod will not turn on, please help.

My problem is different than the other ones posted on the forums, I have a 60gig ipod. Once it turns off I can't get it to turn back on unless I reset the system by pressing the menu and center button. Is there a way without restoring the original settings? It works fine once its on, but it is really frustrating to have to reset the ipod every time I want to use it. And I don't want to create more problems by constantly restarting it, that can't be too good for the ipod. It still syncs fine with the computer and everything. And it has a charge. If I reset the ipod, it will play fine. It's just after I use it, I turn it off, and next time I want to play it, I would have to reset it.

Hi Patrick,
You sound like you know something about a thing or two...Would you know anything about myself and other people 's problems about
the Apple logo flashing on and off with a low whining down sound and then restarting again,and this goes on and on,I guess untill the battery dies.
I have a 5th Generation 80GB Classic ipod.
I went to turn on the ipod and nothing happened. I tried the reset method by sliding the hold switch ON, then OFF, and pressed both the top area of the MENU button and the middle of the SELECT button, at the same time, but with two different fingers.
All I’m getting now is the black screen with the Apple logo appearing for about six seconds, then off for about 6-8 seconds, and ON, over and over again and so far it has been doing this for about fifteen minutes now.
I called APPLE, and they told me to install iTunes, and plug in the ipod, and hit the RESTORE Option, but for some reason, the newly downloaded QUICKTIME and new itunes I just downloaded from Apple does not open up the itunes when I double –click on it either from the desktop, or the Start>Programs>itunes folder.
The reason for all this was that I was clearing off one computer’s hard drive to another new computer before I wipe the Hard drive. I deleted all my mp3’s and the itunes program from the old computer and put the mp3 music files onto the new hard drive. I downloaded the new Quick time and itunes programs separately to my desktop.
I was told from Apple that my ipod warranty has expired by about 85 days.
I have run all the Apple updates and it tells me I am up to date. Thanks for any help.

I don't have a phone plan, so I cannot text without wifi. I have been using iMessage to text my friends, until it stopped working. I can text my sisters email, but not my boyfriends iPhone. The send button will not turn blue. Help? Please?

There is a problem with iMessage with what Apple says is a small number of iPhones and they are working on a fix. In the meantime try this:
1. Settings > Messages > iMessage = Off
2. Settings > FaceTime > FaceTime = Off
3. Settings > General > Reset > Reset Network Settings
4. Wait for the iPhone to Reboot
5. Settings > FaceTime > FaceTime = On
6. Settings > Messages > iMessage = On
You may have to repeat the steps a couple of times.

You probably need to either uninstall and reinstall itunes or to download the apple application support by itself
you can download the itunes http://www.apple.com/itunes/ here
then to do a complete uninstall / reinstall follow these instructions http://support.apple.com/kb/ht1923
you could also use 7zip to extract the individual installer for apple application support from the itunes setup file http://www.7-zip.org

I need to create a second back-up of iPhoto from Time Machine to a separate external drive. The old iPhoto in TM will not open. Please help!

I need to create a second back-up of iPhoto from Time Machine to a separate external drive. The old iPhoto in TM will not open. Please help! And thank you!

Most Simple Back Up:
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex: Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically.
Example of such apps: Chronosync - but there are many others. Search on MacUpdate or the App Store

IBook will not turn on at all

Hello everyone, this is my first post.
My problem: I have a late-2005 iBook G4 1.33MHZ superdrive etc. I believe this is the last iBook Apple made before the MacBooks came out.
About a month ago, with no warning signs whatsoever (so slowing down, no fan wheezing, nothing) the computer just turned off and will not turn back on.
The battery was fully charged and the unit was on AC power when it happened. The green AC light still comes on and the green battery buttons will glow when I push the button on the bottom, but otherwise the machine will not even power up.
Unfortunately I'm no longer under warranty. I'm assuming it's the logic board.
The only other information I can give is that something bumped the left side of the computer about 2 hours before it shut itself off, but not any harder than other bumps my poor little computer has sustained.
Can anyone help?
Thanks,
Chris

Well two things come to mind, actually 3 but 2 are related.
First is the power chip U28 described here:
http://www.coreyarnold.org/ibook/
Diagnosable via pressure or shim as described.
The 2nd would be the GPU chip. It's an ATI Mobility Radeon 9550 4x AGP for the 12" and a 9200 on the 14". I have a 12" 1.33 board that has a dead 9550 chip and there are known failures on the 9200.
So on that same chip there are also BGA failures (the way the chip is soldered to the board) this can also be diagnosed by shim repair or by putting pressure on the chip from the top or the bottom. That chip is generally in the area on the top of the logic board under the option key.
Both problems can be fixed permanently by soldering in the first and reballing in the second case.

IBM ThinkPad T40 - Will not start up - Please HELP!

Hi!
So, I have an IBM ThinkPad T40, and for some reason it will not turn on, The Power Indicator is lit up, as is the battery indicator acknowledging that my computer is plugged in. It worked earlier today when I was at the public library (around 5pm-8pm) but now at 12am when I am attempting to turn it on, it looks as if it's turning on, but nothing happens. I can feel the hum of the mother board, as if it is booting up. Yet, the screen remains blank.
Does anyone know what I can do? I'm unemployed at the moment and use the computer to do art commissions for people, so it and Unemployment benefits are my only source of income. I can't really afford technical support. The computer was a gift from my mother, and I'd really like it to continue working!
If you have a resolution please either reply, or contact me at [e-mail removed]
Thank you,
TurtleSensei

The first thing I'd do is connect an external monitor to see if that works. (Remember to use Fn-F7 to toggle monitor modes.) If an external monitor works then you've got an LCD-related problem, probably a defective inverter card or CCFL backlight.

Doesn't matter when you purchased your phone. All iPhone 5s are still under warranty. Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.
