The battery has a charger limiter that prevents the battery from charging when full charge is reached, therefore connecting the Mac to power with the battery inside will not affect your computer's battery life.

Charging does not charge


If your Notebook computer battery is not charging, try the following:
  • Reset your computer's power manager. For information on how to do this with your specific model, search Apple Support.

    • Make sure your AC adapter is properly inserted into your laptop.

    • Connect your computer to its AC adapter, shut it down, and then let it charge overnight. If it does not charge, it's likely you have a hardware fault in your computer, battery, or adapter, and you should have it repaired.

    • Test your AC outlet. See if your battery will charge if you plug it into a different outlet, or see if another electrical device will work in your original outlet.

    • Test your AC adapter. Try connecting a different AC adapter to your computer and see if it recharges.

    • If it's removable, test your battery. Try using a different battery with your computer and see if it will recharge.

    • In some of the early PowerBooks, the battery will not charge unless the computer is turned on. If you have an old PowerBook and your battery isn't charging while it's turned off, power it on, put it to sleep, and then see if it recharges.
    If you go through all of these steps and your battery still won't charge, or you can't narrow down the source of the problem, you will probably need to have your computer repaired. However, it may be worth your time to consult Apple Support first. It contains entries on problems with specific computer models and versions of the operating system, including battery recharge issues.

I have no power on my laptop but cord works on another mac so it doesn't appear to be the cord


WIthout knowing the models of Mac and AC adapter, I can't give you as much help as I would like. Apple AC adapters come in many power ranges (40W, 60W, 80W, etc.). Although the plugs on them are identical, the power supplies are not identical. If you try to use a low-rated power supply on a laptop that needs more power, it won't necessarily work.
The other possibility is that the power circuitry in your Mac is just bad. Try it with a different, known-good adapter compatible with your model of Mac. If it still doesn't work, your laptop will need repair.

No picture


Hit F2 to brighten the screen. No picture could be any one of these things you need to buy.

1. New inverter board
2. New LCD backlight
3. New power board/sound board
4. New Logic board

If the parts and repair labor becomes cost prohibitive, then look into a new laptop, unless your handy and can replace the parts yourself.

My powerbok g4 got the metal tip of the AC power cord jack broken inside of the DC port of the laptop. This caused some sparks to come out of the port when the cord was plugged in again, so had to charge...


You need this part replaced bud:

But you can't just buy this one. You have to buy the one that fits your model and processor speed.

Macbook will not power on. It's not the battery according to the Genius bar technicians


I assume it doesn't power on from the AC adapter either?
If not, perform the following steps:
  1. Disconnect the AC adapter and remove the computer's battery.
  2. Press and hold the power button for 5 seconds and then release the button.
  3. Reconnect the battery and AC Adapter.
  4. Press the power button to restart the computer.
If it doesn't restart, you have logic board issues, and need to bring the machine in to a service tech.

Laptop not charging


Double check and make sure that the AC power cord is ok and that it's firmly connected to the laptop. Also check and make sure the cord or part that goes into the AC adapter converter is plugged all the way in. Finally, most laptops will have some sort of a "Plugged in" indicator or LED light on the laptop indicating that it's plugged into 120V AC. If you seen nothing like this, then it is most likely the power cord. If your battery is bad or was going bad, the laptop should still work when plugged in. Finally, make sure that your battery is firmly seated into the laptop. Some laptops will not function when there is no battery, even when plugged in. If you determine that either the battery or plug is defective, of course, you can order a replacement online or from the manufacturer. You can also try EBAY for better prices.

Good luck!

Macbook Battery Problems


Hi Molle
To answer your last question first. It is best if possible to use the mains power when you are using your macBook and only use the battery when you cannot connect to mains.

MacBook batteries have a life span based on the number of charge cycles the battery has been through. The battery has a max of 300 cycles before it starts to loss its charge capability. SO you need to determine the health of the battery is it chargeing etc. You can do this via the apple menu and 'about this mac'

http://support.apple.com/kb/HT1519

Check the health of the battery as the battery could be faulty if it has only cycled a few times or it may have gone over the 300 and is now lossing its charge in which case you'll need to get a new one.

Hope that helps

Paul
