    Hi kirkmiller
    the green light comes on for a few seconds when I first power up the laptop then it changes to orange.Yes the light changes to green again when the laptop has been powered up for quite some time and the battery is fully charged,the laptop is working fine, however until I used a new power supply which I strongly suspect was faulty the green light was on permanently I had never seen the orange light before this

    Thanks Kirkmiller for your help,as I had not seen the orange light in the past I was concerned there was a problem that might damage the laptop

    if you leave the power supply plugged in, AND the battery installed will the orange light eventually turn green? Does the computer work fine with the orange light on? (It should).

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!

Won't start up


Either power or logic board problem. If it chimes but does not boot and the screen lights up then it is a good sign. Will it do anything?

If does nothing try a different power supply first.

Try removing battery and disconnecting power supply, then try to start it without battery and just power supply.

then try charging the battery overnight. If the lights on the battery show any charge after a few hours with it plugged in and the computer turned off, try letting it charge overnight and then try starting it without power supply connected. If none of these thigs help, I would have to look at it.

To help with getting your battery to charge, try resetting the PMU

-PMU RESET-
The Power Manager (PMU) is an integrated circuit (computer chip) that is usually on the logic board of your Mac computer.

It is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

• If the computer is on, turn it off.
• Now refer to this article from Apple.com Support
Resetting the PMU for Powerbook and iBooks

If this process does not help to allow your battery to charge normally, you more than likely have a battery which may be either dead or eventually will die in its charge capability.

What I would recommend if that is the case, would be to consider purchasing a new battery from Apple or via a third party reseller like online Apple authorized resellers like Amazon.com, MacMall.com or Fry's Electronics for example. You may also Google with keywords "purchase iBook battery " and shop for the best priced iBook battery.

Again, you would only consider the latter, if the former procedure listed above does not help.

I hope this helps.

I push the power and nothing happens on my ibook g4 14-inch


If you are not using the AC adapter (you are using only the battery), then the battery may be dead - simply replace the battery. If you are plugged into the wall, and the light on the power cord, where it meets the computer, is green, the unit is receiving power. If the unit is receiving power and it will not boot at all, then either the motherboard or the hard drive is most likely problem. You can replace the board, but it may end up being more expensive on an older G4 than it is worth. Once you are able to determine if the unit is receiving power, the only thing you can really do from there is take it to a repair shop and have them perform a test on the power supply, hard drive and/or the motherboard to see which one of those is causing the problem. If the hard drive is fine, you will most likely be able to recover your files.

Describe your cannot start ibook G3Problem it simply does not start, battery is ok and I have tried to take the battery away and back in its place, but nothing what can I do?


Make sure your iBook is plugged in to the wall. Hold down the power button for a few seconds. If that doesn't work, try holding down Command (the Apple key)-Option-P-R (hold all four keys down) and press the power button. Be sure to hold the power button for a few seconds whenever you turn it on.

If that doesn't work, try resetting the Power Management Unit (PMU). This is kind of a "last resort," according to Apple. Don't do this all the time.
  1. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
  2. Wait 5 seconds.
  3. Press the Power button to restart the iBook computer.
If you have a very old iBook, you may have to unplug your iBook, remove the battery, and
  1. Press and release the reset button located above the Audio/Video port on the left side of the iBook (Dual USB) computer by inserting the end of a paper clip into the small hole and gently pressing the switch once.
  2. Wait 5 seconds.
  3. Reconnect the AC power adapter.
  4. Put the battery back in the computer.
  5. Press the Power button to restart the iBook computer.
(If it still doesn't start, do you hear the fans going?)

Good luck! Let us know if these steps solve your issue.

My iBook G4 will not turn on though it has a full battery & is connected to a plug socket also..


There are several models of iBook G4. The following sequence applies to the "14-inch Early 2004."
Remove all peripheral cables. Remove the battery. Reset the power manager by pressing the key combination Control-Option-Shift-
power. Then plug the iBook into AC power and attempt to start it with the power key.
If this procedure does not being it back, invasive diagnostics are required, in which case you should being it to an Apple-Certified tech for repair.

My laptop battery won't charge


Check the power adapter with a multi-meter, the voltage of the power plug that plugs into the power socket on the laptop should be slight higher than the voltage that is printed on the label on the adapter.
If it is faulty, there are replacement power supplies available on the Internet or at your friendly computer shop.
If the adapter is OK then the power socket on the laptop is faulty or this socket has a dry solder joint connection on the motherboard.
You can test this by wriggling the power plug when it is connected to the laptop, if the charge LED flickers and if you hold this plug in a certain position the charge LED stays on without flickering, then the power socket is faulty.
This can be repaired, but requires the laptop to be completely
disassembled. I suggest you get a quote first.

Ibook g4 rebuild


Hi there.
Make sure you have the voltage and amperage right first before you try and power up the motherboard.
Most laptop motherboards run on 15, 19 or 20 volts and take a different amperage like 3.42A for example.
The power in will be displayed underneath the ibook so take a look there.
Don't plug a 24 volt power supply into it unless it specifies that because you could damage the board.

Good luck with project

On an Apple system, this is an indication that it thinks there is little or no battery left and goes to sleep to protect data loss. Your battery might be going bad (showing a full charge, but lasting for only a few minutes) or there may be a problem with your power supply.
