Imac G3 233 starts up a few seconds then power goes down

Hello
I have an imac G3 233
It has been working and i have just plugged it out for 6 months. Now i plugged it in today and it boots up . startup sounds comes ok and hd spins up. Power button is light up.
After a few second the power goes down.
And i have to unplug the power for a while to be able to get it to boot up like that again.
I am clueless ... Any ideas on this?

Hi,
If anything occurs when the computer has been disconnected from the mains for some time, one thing to suspect is often the internal battery. When the voltage falls below approx. 3.0 V, at the latest, the battery should be replaced (the nominal voltage is 3.6 V). Have you noticed any changes as far as the date and time settings are concerned?
Unfortunately, problems in the analogue board area can also affect the ability of certain older iMacs to start up properly.
Please note that working inside an all-in-one Mac is dangerous, and must be carried out by someone who knows exactly what to do. High-voltage charges can remain in various components even if the machine has been switched off.

Nano 6th turns on for a few seconds then screen goes black and nothing. what is wrong with it....

My 6th gen nano turns on for a few seconds, then screen goes black and nano goes off. what is wrong with it? can any one help me out? do I need new battery? do I need a full repair? or is there something I can do myself to fix it. Thanks for your help.

At the moment I say as I've fixed, momentarily:
I made a downgrade to 1.0
The problem, gentlemen, is the upgrade from 1.1 and 1.2
It is a pity that I lost all the new features offered by the new firmware , just because Apple staff could not think to try this new update, on ipods with some airtime.
I hope Apple pull out a version 1.3 with the ability to choose the feature detection, and the user can disable it at will.

When I turn on my iMac the white start up screen appears but then it goes onto a black screen

When I turn on my iMac, the white start up screen comes on with the noise. Then when it's supposed to show my accounts the screen goes black but I can still use the mouse?

Macbook Pro...will work for a few minutes, then power goes out all together

Hey guys, tried finding an answer to this somewhere else on the forum, but came up empty. If this has been answered elsewhere, feel free to direct me there.
I have an older macbook pro (2011) that's in rough shape, but worked well up until recently. The symptoms I'm experiencing:
-The computer will charge (all lights are showing green on the charger and the computer)
-When I try to turn it on, sometimes it will turn on fine. Other times it will light up, then shut down immediatly
-If I remove the power cord and insert it again, sometimes it will boot up
-When I can get it to boot up. It will run fine for about 1-2 minutes, open all the programs, then shut down/black out all together (as if the battery was removed)
I'm assuming this is a hardware issue, or a cord issue, but not sure where I should be targeting my efforts. Any ideas? Thanks !

My iPhone 3G phone button no longer works. If I push it I get a black screen for a few seconds then back to the home screen. Everything else is ok. Any ideas how to fix this?

The phone button on my iPhone 3G no longer works. Everything else on the iPhone works fine. I can receive incoming calls. I can make calls directly from Contacts. But if I press the phone button I get a blank white screen for a few seconds then it goes back to the home screen. I've tried the hard reset and also restoring orignall settings via iTunes but keep getting the same problem. Does anyone know how to fix this?
Thank you, Neil.

Thanks for the advice but I've tried resetting network settings and also the reset by pressing home and sleep buttons until getting the Apple logo. Still have the same problem. To be clear (because I mistakenly typed black instead of blank in the title to this thread): If I press the phone button I get a BLANK WHITE screen for a few seconds then it goes back to the home screen. I doubt it's the SIM card as I can receive calls and make them directly from contacts. What I can't do is view my favourite numbers or missed calls or access my voicemail, i.e. all the things you get to via pressing the phone button.

My HTC 1 phone is completely charged and after a few calls the battery goes down Why?

HTC One

We certainly want you to get the most out of the device! To confirm is this the HTC One M7 or M8? When checking Settings>Power, what are some of the top apps and processes using battery? The battery is warrantied for one year so it is possible it is past its prime. Only HTC directly would be able to review replacement options of only the battery. I am eager to continue troubleshooting though!

Try to backup and restore you device in itunes...restoring the device is like removing the iOS software off the device and re-add in a newer software, after you have restore you device, MAKE SURE YOU SET UP YOUR DEVICE LIKE A NEW DEVICE, DONT NOT RESTORE FROM BACKUP!!... give the device a chance to use the newer software and see if the issue still persisting, if the issue still on going then its would be a hardware issue.
Call Apple Care and see if your device is still under warranty to get it replace

I cannot sync my iphone 4 to my imac it connects for a few seconds then goes off

please can someone help me When i connect my iphone 4 to my imac using bluetooth it pairs up but only lasts for a few seconds then goes off and shows
not connected i have tried all sorts of ways but without success why is this happening am i the only one does anyone know the answer please

Seems like my problem - I have a new iPhone 4 and it does not want to pair with any device. It seems to connect, and is recognised by my MacBook pro, it shows the code that my Macbook shows, but then says it cannot connect. Neither did it connect to another imac, nor does it connect to my carphone. Have received a replacement (as I had bought the iPhone five days ago), have a new one now, but exactly the same problem. But I cannot alter the bluetooth settings on my iPhone, and restoring does nothing, nor leaving it in the completely unaltered setting, nor switching off all other wireless devices. Does anybody know how to solve this?

Try resetting the SMC 2-3 times, if that does not work then the DVD may need cleaning. Get a dry cleaning kit from your local office supply store.

Music app stops playing for a few seconds then starts

After updating to lollipop the music app would play for a few minutes then stops for a few seconds then play again, did not have issue with kitkat. Help please.

It's back!!!!!! The problem went away for a few days now same issue. It only happens when I am listening to sound files on the headphones - sudden pause then restart in the middle of playing the sound file, this happens with different music/podcase apps. No issue with bluetooth streaming or speaker phone. So it appears there is a software bug with Lollipop update - never had this problem with KitKat. Factory reset does not fix it. I wish there was a way to revert the phone back to KitKat. Hoping the new Lollipop update would fix this.

I just figured out the print quality issue for my wife with her new iMac and new printer.
She replaced both at once and she couldn't understand why her Artisan 730 was lower quality then her Epson R280 when they had the same specs.
Turns out the newer printer had the option to connect via wifi which we used during setup.
The driver options are completely different depending on how you connect.
Once I connected via USB the correct options were available and the print quality was better.
Looking at the R2400 it dies not have wifi, but while researching the problem for my wife someone esle was having an issue updating to the latest printer driver.
If you go into the print utility from the Printer and Scanner system preference and under the general tab you should have driver 5.5.
One user had to delete the old printer driver before Software Update loaded the newer printer driver.

On my MacBook Pro (w Snow Leopard) I always had to reconnect my wifi at home when it woke up. I upgraded my router from an old Netgear to a newer N D-Link and stopped having to do that.
I would be surprised you would have that problem with an Airport Extreme, you might check to see if there is a firmware update for it.

QT playing video a few seconds then turns green

I've tried a bunch of things but still can't fix this problem. When playing back a quicktime file either streaming or downloaded, video plays a few seconds then turns green and starts using a lot of system resources. I'm using Nvidia video card and have no problems playing any other types of media. Is this a problem with codec or QT7 and graphics card?

Always best for initial first time startup, to do it with just one RAM stick in the primary blue dimm slot. A couple thoughts, first is use just the one RAM stick & load the OS & all the drivers, then add the other sticks. The other thought is to try each RAM stick individually in the primary slot to rule out a bad or failing stick.

I notice my graphics card is very hot
That can't be a good thing.

My MacBook Pro, even when connected to the power chord, will turn on for a few seconds then shut back off. Any ideas on what is wrong?

I Am trying to turn on my MacBook Pro laptop, but when I do, it starts to turn on for a few seconds then shuts off again. It has around 80% charge and even if the power chord is connected it won't turn on. Need some help because I am out of the US right now and there are not a Mac store or anything that I could go to.

HAve you tried using a different power chord? If the power chord is not the issue, it could be the power supply inside your mac.
