    quit wasting people's time. If you were a doctor, could you do anything if someone left a phone message stating: "I'm dying, I'm breathing, what's wrong?"

    Describe Symptoms, onset, anything that happened that started the problem. Anything you have done so fart o fix it (that was an unintentional mistype, but I had to leave it). I'm going to quit typing because you've probably forgotten that you even posted this and posted the same useless fragment of a question on 12 other sites and are still baffled as to why no one has fixed your problem for you.

1) Try your battery in another Mac.
2) Try a different battery in your Mac.
3) Try your power adapter on another Mac.
4) Try another power adapter on your Mac.

Go to an Apple Store if you don't have a friend you can borrow equipment from.

If your battery and power adapter work perfectly on another Mac, and working power adapters and batteries do not make your Mac turn on, then your Mac is broken internally and you need to take it to the Apple Store to get it repaired.

    You may have overlooked a very important step. The first thing that should be done, because it requires no extra hardware and is very quick, is to reset the System Management Controller (Intel Mac) or Power Management Unit (PowerPC Mac). URLs to steps:

My laptop won't charge. It was working when plugged in and now it won't even do that. Will replacing the battery fix my problem?

It sounds like your battery and your charger are not working. Changing the battery should help, but you should first check to see if you are getting voltage to the laptop. Does the green light on the magnetic end (the end that plugs into laptop) light up when plugged in? If so, your charger is working. You should be able to turn on the laptop with or without a battery (even a dead battery) with a good power supply. If you can turn it on, check to see the number of battery cycles you currently have.

Follow these steps to access information about your Mac notebook battery including the cycle count:
  1. Your first step will vary depending on which version of Mac OS X you are using:
    • OS X Snow Leopard v10.6.8 or earlier: Open Apple System Profiler by choosing "About this Mac" from the Apple menu. Then, click More Info.
    • OS X Lion v10.7 or later: Open System Information by choosing "About this Mac" from the Apple menu. Click System Report.
  2. Click Power in the Contents list (under the Hardware section as shown below).
  3. The current cycle count is listed under the Battery Information section.

Take notice of Full Charge Capacity (mAh) on your machine. It should be close to the number shown above. If it is much lower than that and/or the cycle count is above 1000, it is time to replace the battery. I hope this helps.

This may indicate that your battery is going bad and not holding a charge. Try inserting a different battery and see if the light stays green.

My notebook doesn`t come on when I turn on the power switch.

Check the battery by pushing the button on the bottom, if it shows one light flashing or no lights then the battery is discharged. The problem may be with the ac adapter. Many of these connectors fail after a while and they don't charge the system, which means when the battery dies, there is no more turning on.

Won't turn on

Did you try to disconnect the battery and connect you mac book to the charger? If it turns on with the power connected and without the battery, probably your battery is broken.

Mac Ibook Power supply problem

On Mac iBooks the orange light comes on when it charges the battery. Once the battery is charged it turns green. Im guessing the other powersupply was aftermarket or broken. EIther way, if it starts out green - recognizes the battery isnt full - turns orange for a while - then turns green when the battery is full, then the computer and powersupply are working perfectly. Enjoy your iBook!
