Macbook only on when AC is plugged in, even though battery 100%

Hello,
I have had my Mac since december 2006 and it has worked perfectly, suddenly my laptop won't start up without A.C plugged in !
My battery is 100 % full, when i try to start up without AC i normally get the sound of the disks and fans spinning and a slight part of the welcome chime then it cuts dead. I see no screen either. With the AC it works fine. So it seems to me that the problem is not the battery but the laptop itself. I went into the 'System Profiler' to have a look at what it said, the only thing that i thought might be odd was that UPS was not installed (Uninterruptible Power Supply). Is This a problem ?
Thanks T.Gibbs
P.S if i can't find the solution on here what do i do ? I live quite far from an apple store and so don't have a chance to go and speak to someone there, my 90 day phone support has run out. I don't know how to contact someone about this ?
Macbook 2.0Ghz Core 2 Duo - 2GB Ram - 120 GB Hard Drive Mac OS X (10.4.10)

The MacBook does not have a UPS built in. That would be in something like a desk top.
You might try to reset the SMC and/or PRAM.

My ipod nano 4th generation only works when it is plugged into the computer; otherwise, the screen turns black and it is completely unresponsive to any efforts such as pushing buttons, reseting, etc. What should I do?

Sounds like the battery is shot and in need of a replacement. You can have Apple replace the battery for a flat fee or you can send it into a third party repair center for a bit less.
Not much else you can do for troubleshooting this one.

I have lost sound on my iPad in apps unless I use headphones ,does anyone know how to get sound back without them .I have used the mute volume on the bar at bottom of screen and the slider volume control there only shows when headphones are plugged in !

I also tried resetting settings all to no avail ...I looked up some advice and watched utube video advice on how to fix without success..
The volume control button on side does not work ,I got the iPad last August and wonder if it is a fault that means I must return it for replacement from where it was purchased ?

The Retrospect you used way back when is no longer around. The company was sold and that company produced a new version of Retrospect - Retrospect 8.x
So, as you've been told, you would have to be running a Tiger system with an old version of Retrospect software (5.x or 6.x - you would need to know) assuming you can find the software.
As best I can remember you cannot extract files from a Retrospect backup except using the software since Retrospect did not normally make a file by file backup rather it created an archive of the files in the backup. I'm assuming that the EMC/Retrospect people have told you that old Retrospect backups are not accessible by Retrospect 8.x?

Do i need a new battery if my computer only works when it's plugged in?

my lap top only works when it's plugged into the adapter. it doesn't CHARGE anymore. it works fine when plugged in but shuts off if it's not. Do i need a new battery? i just got a new charger because the one the computer came with died. please help!

Go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report if you are running 10.7 Lion or 10.8 Mountain Lion), then select Power from the left hand column of the System Profiler. Copy and paste the Battery Information from the top of the page back here.

It says cannot connect to iTunes store when I click purchase history even though I'm connected to iTunes store

It says cannot connect to iTunes store when I click purchase history even though I'm already connected to the iTunes store?

Same phone and ios, same problem. Worked just fine for me Sunday, but nothing today, all day. As a workaround I found I can still connect using iTunes on my Macbook Pro, the I synch my iPhone. There are way too many people with the same problem for it to be anything but Apples problem. Hope this helps.

Wrong! Check out KB Article: Intel-based Macs: Using Apple Hardware Test
Personally, I would not be running no test. Apple has a 90 day warranty on all their repairs. Return your computer to the repair shop but this time.......
When it’s time to pick up your computer from the repair shop:

absolutely that is frustrating. if the battery life is fine there could be two things software or hardware. to find out if your back up your information in itunes and import pictures and then restore the phone as NEW then you can test it out. if it is still shutting off it is hardware related

HT4157 my ipad 4 connects to LTE when I am at home, even though I have wifi. The LTE seems to connect first, bypassing my wifi, and it costs me money. i know i can turn it off on settings but then when i leave home and turn it back on i forget to turn it

my ipad 4 connects to LTE when I am at home, even though I have wifi. LTE is faster so it connects first, which costs me money. I know I can turn LTE off on settings but then when I turn it back on when I go out I forget to turn it back off at home.

My iPad will show a cellular connection even though it is using Wi-Fi as long as I have cellular turned on. Are you sure that your iPad is actually using the cellular instead of Wi-Fi?

TS3700 My ipod stills pauses when the display turns off, even though, my headphones are correctly attached (or flushed)

Does this happen still when you use another set of headphones? Have you check to make sure the headphone jack is clean and clear of debris? If so, the jack may be faulty or damaged meaning you'll need to take or send your iPod in for service/repair.

Speakers only play when headphones are plugged in.

My internal speakers only play when the headphones are plugged in. (System preferences-Sound tells me I'm using Internal Speakers, audio port for sound input). When I remove the headphones, the red light in the jack goes on and the computer says I'm using Digital Out ("The selected device has no output controls.)
I have read many community responses, most saying that the switch inside the headphone jack hasn't engaged, that I should fiddle with it using a paperclip/bobbypin/toothpick or just plug-in and unplug headphones repeatedly. I have repeatedly both of these to no avail. When fiddling, I don't really know which bump inside there is the switch, I've played with them all.
No, it's not dirty, I've blowin air, vaccuumed, dusted. Same problem.
I do use my speakers often for work and pleasure, go between different external speakers and a projector.
It seems that the computer has things backwards- headphones unplugged is pluged and vice versa.
Any suggestions or clear guidance as to what I should be fiddling with when I stick a bobby pin in there? No need to refer me to old posts, I've read them.
Thanks in advance,
TheKip

If your phone is still under warranty, Apple will service your phone for free.
Did you check the headphone port for any kind of debris or lint?
Did you already try another set of headphones? Are you suing the headphones that came with the phone?
Is the headphone jack plugged in fully into the headphone port?

Why does my iPod Nano only work when it is plugged into the computer?

My iPod nana is a 4GB iPod and it does not work at all until it is plugged into my computer. It works perfect when it is plugged into the computer. It will not even turn on if it is not plugged in.

By the sounds of it, the Nano's battery is shot and in need of a replacement. You can have replace the battery for a flat fee or send it to a third party repair company for a little less.

Can I use my Macbook Air 13" mid 2013 with plugging charger even at 100 % battery full charge?

I can't decide whether using My Macbook Air 13" mid 2013 with charging power adapter connected even though it is fully charged Or using Macbook Air with unplugging charger after fully charged. Please advice me to maintain my Macbook's battery at good condition.

It will not hurt it as long as you do not leave it on the charger for an extensive period of time (say, days).

IPod Classic won't turn on unless plugged into wall even though battery is charged

I plugged in my old iPod Classic and charged it up for a long time. I got that little plug symbol that indicates that it's fully charged. The iPod turns on and works fine when it's plugged into the wall, but as soon as I unplug it, it won't do anything at all. Just black screen. I also tried plugging it into the computer. Nothing.
I tried re-setting by toggling the "Hold" button and then pressing Play/Pause and Menu at the same time. Nothing.
Why would it be fine when plugged into the wall but not when unplugged or plugged into the computer? Is it possible that is really is not fully charged even though it did show that little plug symbol? It had been just sitting for many months.

Hi there,
How old is your Classic? Often, after a couple of years, rechargable batteries begin to fail, especially after such a long period of inactivity. This happens with any gadget with this type of battery.
Try leaving it plugged in for 24 hours, and try again, to rule out that it isn't just really low on charge. If this doesn't help, it may be a good time to buy a replacement. New iPod Nanos and Touches will be released this October.
Below, I've linked to an Apple website which explains rechargable batteries, and why yours may not be working.
Apple - Batteries
I hope this helps, and I hope upgrading your device will not feel like an unnecessary expense. Let me know if you have any more questions,
Nathan

My ipad mini gets 100 % charged but the plug in icon doesnt always comes out. Please help me. The icon is always the lightning bolt even though its 100 % charged already. Why?

PLease I need help. My ipad mini wont fully charge. It says 100 % charged but its still shows the lightning bolt

The plug icon will show as long as the device is connected to a power source. Yes, 100% = complete, at least where I was taught math. Your fears about destroying the battery are unfounded. You can leave the device plugged in even after it's fully charged. It will stop charging.
Best of luck.

Mini sleeps when display/TV powered off, even though apps are runnning

I have a new Mini (Late 2012) running 10.8.3, it is connected to a Samsung TV running Elgato EyeTV(HDHomeRun), as an HTPC.
When we switch to another input on the TV or power off the TV, the Mini sleeps, even though I have all the Energy settings to Never!
This box has our recording schedule and must be on 24/7 wether the Display is on or not.
I have sent crash reports from EyeTV to Apple related to the problem but have not seen any updates.
I've tried connecting the display from the HDMI and TB/Display port with the same results.
Mini Specs: Late 2012, Macmini6,2, 16Gb Ram, 2.6GHz i7, 1TB disk
I've waded through all the discussions and haven't seen any solutions/recommendations that I haven't already tried.
Is there a way to tell the Mini not to sleep when the display is diconnected or powered off?

Hi, no idea what you tried, but...
Open console in Applications>Utilities, check the system log for the date/time of the last problem & the Wakeup/Startup right after that for clues.
