My PowerBook will not power on

I restarted my PowerBook, and it makes a loud noise like the HD is working hard, then 1/4 of the bar shows loading- then it just shuts down.

You can use your PowerBook in FireWire target disk mode to transfer data to another machine, but I'm afraid it'll still need to be powered on...here is a description from Apple's support pages on how to use Target Disk Mode;
To use FireWire target disk mode:
Make sure that the target computer is turned off. If you are using a PowerBook or iBook as the target computer, you should also plug in its AC power adapter.
Use a FireWire cable (6-pin to 6-pin) to connect the target computer to a host computer. The host computer does not need to be turned off.
Start up the target computer and immediately press and hold down the T key until the FireWire icon appears. The hard disk of the target computer should become available to the host computer and will likely appear on desktop.
When you are finished copying files, drag the target computer's hard disk icon to the Trash or select Put Away from the File menu (Mac OS 9) or Eject from the File menu (Mac OS X).
Press the target computer's power button to turn it off.
Unplug the FireWire cable.
I know you said you tried everything, but have you tried Resetting the PMU on your PowerBook in attemt to get it to turn on?
Good Luck,
Geo

My Powerbook will not power up, but I can hear the fan running...

Please help!! My Powerbook will not power up, but I can hear the fan running when I press the power button to attempt to power it up. I just received a new power adapter because it wasn't working properly and it was doing this before and then it worked for a week and now it will not power up at all. It just starts the fan but nothing else turns on. When I plug the adapter, with the battery still connected, it will look as if it is charging but then the light on the plug turns from green to orange then off and doesn't power up at all. If I take the battery out and plug in the adapter, the light stays on but it does not power up except for the fan noise. Does anyone have any suggestions? I also followed the two articles listed online in regards to resetting the power setting and the command + alt + P + R as well. Nothing works. Thanks in advance.....

Same here. If I start up with the power adapter attached, it starts up fine. If I try to start up from battery only, the fan comes on, the sleep light comes on but nothing else happens. I tried letting it sit that way for about 15 minutes and nothing changed. I tried attaching the power cord while in this mode and nothing changed. I tried the PMU reset a couple of times but nothing helps.
This computer is just over 1 year old and I have not had any problems with the power cord (3rd party), the battery, or any problem like this before. It started after a proper shutdown last night and attempt to start without the power cord this afternoon.
Any answers to this yet? I think I'll call on this and report any success to this discussion.

Powerbook will not power on

Hi folks.
What led to this problem is this: My AC adapter cord broke and while I was waiting for a new adapter to arrive, I left the computer on and the battery ran down. So after a week the new adapter came and I plugged it in and... nothing. Not a blip, whir, buzz...nothin'. My battery has little charge so it will not power on the computer on it's own. I thought maybe the AC adapter was not working but I have since tried another adapter and still no response.
I tried the procedure to reset the Power Management control; but it failed to work. That is, I took out the battery, unplugged the AC and then held down the start for 5 seconds. No response.
How do I raise my Powerbook from the 'dead'?

Hi, Ddale. Remove the main battery and leave the AC adapter connected to the computer for five or six hours. Then try starting the machine up on AC power. If that works, it will be because you've recharged the Powerbook's internal backup battery, which went flat while your AC adapter was disconnected and the main battery was drained. If a drained main battery is present, it can take up to 48 hours to recharge the backup battery. Removing the main battery lets it happen much faster, in four or five hours. A drained backup battery can prevent a Mac from starting up, even when AC power is available.
If the machine still doesn't start up after you've given the backup battery time to recharge, reset the Power Manager and try again.
Once you get the machine running, reinstall the main battery and let it charge up normally.

HT3046 I have a Powerbook G4 that I have not used for a number of years. I believe there are photos on it that I want to retrieve. The unit will not power on and there is no evidence it is alive. Neither the wall plug in or a new battery helped. Sugge

My G4 will not power up. I installed a new battery and still nothing. Help.

Try taking out the main battery and letting the PB sit turned off but plugged into wall power for 24-48 hours. Then reinstall the main battery and try a start.
When you try to start it, do you get any sounds, like the Mac "chimes" or hear the hard drive or optical drive spin up? If you get those sounds, try holding teh SHIFT key during startup; keep holding until you see a desktop and then lt go the key. Don't try using the comptuer at this point--it won't have all needed extensions loaded. Simply try a normal start to see fi that gets a regular desktop,
Do you have the system install/restire disks that came with the computer, or retail install disk? Both are bootable. Try booting from one of those optical disks. Hold the c key to force booting from the optical drive.

Need Help HP DM3 (DM3-1130us) Laptop will not power on. No power at all except for light on a/c jack

Hello, I need some help.
I have a HP DM3-1130us Laptop that will not power on at all.
the only thing that happens when I plug it in is the power jack lights up.
When the power button is used absolutely nothing happens.
No power, no fans, no leds, no on/off cycles, no beebs, absolutely nothing
just the light by the power jack that says the cord is plugged in.
The laptop has Windows 7, 320gb hdd, 4gb ram.
I have tried new power adapter and still nothing.
I have taken the battery out and tried and nothing.
I've tried the option where you take the battery out and hold the power and nothing.
I have tried with different hard drive and no hard drive and nothing.
I have tried reseating the ram and tried new ram modules still nothing.
So I am kind of stumped on what to do, the laptop will just not turn on.
Its not under warranty anymore so cant send it off.
It has not been exposed to any elements(extreme heat or water).
and its never been dropped or anthing.
Im kind of wondering maybe the power button board its self is bad?
If feels fine, its not loose or anything but could it
have just stopped working? for those who are not familiar with this model.
the power button is on the side and is a kind of drag and release button.
Its also on the same board with the Wifi button and 2 Usb ports.
But Im wondering before I buy a new one if this is what it could be.
Or could the motherboard its self be bad?
But even if the motherboard is bad would it still power up
just not post?
Also does anyone know of any other way to try to power this laptop up
without using the slide button. I mean kind of like off a Dv6000 you can power the laptop on by using the Quicklaunch buttons on top but this laptop does not have those.
If anyone can provide any information I would appreciate it.
Thank you.

Hey Tyler,
Unfortunately it is difficult to troubleshoot this type of issue. The majority of the time when the computer wont power on with the same symptoms you described, the power supply board is faulty. Most of the time if the motherboard is bad it should at least turn on or so some signs of life. Like I said, this is most of the time. Sometimes it could do exactly what your experiencing. I would suspect the power supply board has failed since you are not receiving any sort of lights, sounds, etc.
You could check the motherboard for swollen capacitors or loose solder joints but sometimes you wont be able to find anything.
I hope this helps answers your questions,
Sean

My iPhone 5s will not power on and I need my serial number for support.

I am attempting to get help through Apple Support- Chat, but I need my serial number. It is not showing up in iTunes under the device preferences. Any other ways to retrieve the serial number through iCloud?
If anyone has any idea of what is going on with my phone, I would love some assistance. I live 45 minutes from the nearest Apple Store. Here's the situation:
About 2 weeks ago, my phone started shutting itself off and restarting randomly.
About a week and a half ago, I would randomly get a blue screen and then the phone would restart multiple times.
About a week ago I turned off Touch ID in an effort to resolve the issue, after reading some fixes from this community. That seemed to help. I do have the animation turned off, so I had read that there may be an issue between the Touch ID and animation reduction. If that had not helped, I was going to turn the animation back on.
Last night my phone seemed fine. I did hear it restart in the middle of the night once, but this morning it will not power on at all.
I tried connecting it to my computer through iTunes, but iTunes does not see it and I cannot access the device information from it.
My phone is less than a month old, and for the first two weeks it worked great. I am taking it into the AT&T Store today where it was purchased, but I don't really have high hopes for a resolution.
Any help is much appreciated!

Sorry AT&T store won't be much help.
I suggest you make an appointment with the Genius bar and then go to the Apple store.

Macbook Pro will not power on without battery installed

Hi there,
I have a Macbook Pro A1226 that fails to power on without a battery installed.
i.e. will not run off AC power on its own. I have tried 2 other power adapters, no change. All 3 adapters are outputting the correct voltage without fluctuations.
But, if I am in OSX with a battery plugged in, shutdown the laptop, remove the battery while AC is still plugged in, it will power back on without any issues. But as soon as I remove the battery, it will not power back on using just AC.
Is this an I/O board issue, or a mainboard?
I have power drained the unit and reset the parameter ram.
Thanks

Any update on this? This is the same thing that's going on with my laptop right now. I was at the Genius Bar and they said they can send it in for repair. Takes 7-9 days and costs a minimum of $310. At the time I was there, my computer wouldn't start up at all, because the battery had drained to less than 20%. It didn't even start with just the power cord (no battery in). The "genius" finally got it to work by doing a PRAM and SMC reset. Got home and was able to recharge my battery to 100%. Used my computer for 2 days before I dared to take it off the power supply. Lo and behold, as soon as I take it off the power cord, then re-connect it, it shows "Not Charging". I tried to do SMC again, but no luck. Keeps saying "not charging". Even tried with a brand new battery. Do I have to get the I/O board thingy replaced?

Ipod touch generation 5 will not power on

My ipod touch generation 5 will not power on though it was showing to b e fully charged. I have been pressing and holding the on button on the top which usually cause a the screen to light up. Is there some way to get it to work?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

HP Pavilion dv6000 will not power up.

I have had an HP Pavillion dv6000 for a few years, and suddenly, it will not power up at all. I can not determine that anything at all happens when I press the power button. What's weird is that when I connect the power, the AC LED (the one with the lightning bolt above it) lights, and stays lit for 30 seconds, and then turns off. During that time, and thereafter, the power light will not come on at all, and the computer will not power up. I have tried removing the battery and power cord and holding the power button for 45 seconds, multiple times, but nothing seems to work. I hope you can offer some advice on things to try.
Thanks,
Zach
This question was solved.
View Solution.

Well, I've had the problem for a while and was just looking around to see if anyone has had any success stories.
I will tell you how I get mine up and running, but first some background. I was gifted this computer DOA and asked to retrieve data which I was able to do but in monkeying around, I discovered a "fix".
You see, I live in an area where we occassionally lose power for a day or two or three so the weakened battery never outlasts the outage. That's when the unit becomes unstartable.
Now the fix:
It is a variation of all the other suggestions about undoing the power cord and disconnecting the battery but here's the twist: After removing the battery and power cord, wrap your laptop in one then another plastic shopping bag and place it in the freezer for about an hour or two. Now, when you take out your shivering laptop, plug in the power cord and fire her up. It has nearly always started for me after this trial by cold but once or twice it needed more chillin'. Once it is started, insert the battery. I've never had any issues with this sequence.
You will have a lot of condensate on the screen but gently wipe it up with an absorbent cloth and let the rest of air dry as you let it run.
As long as I leave the computer plugged in and not reliant on the battery, it has never died on me.
Hope this helps!

External hard drive will not power on

I have a PH3200U-1E3S and it will not power up, every other push of the power button the light flashes once. I dont know what to do, any suggestions? The unit is not very old and it has all off our pictures on it.
please help,
Thanks Tony

If it is out of warranty, you might try opening it up and looking for a fuse inside. If you find one and it is blown, you should easily be able to find a replacement.

2nd Gen Time Capsule - will not power up - just stopped working all of a sudden - I have tried other power outlets - I have tried pressing the reset button - no light

The power supply is shot. But that it lasted even this long is the wonder.. not that it died.
The TC runs too hot..
Look on ebay for "Time Capsule power supply"
You can get a replacement and fix it although the economics are not so good.. it is probably time for a new TC.
If you can DIY it is really only a few dollars worth of capacitors that go bad.
