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.

Check if the AC Adapter brick is getting warm when connected, if not then you need to replace the Adapter.

If AC Adapter brick is getting warm and still its not charging the Battery, please perform the following steps.

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter and do NOT connect the battery now.
5. Turn on the Notebook power.

Note: With an extensive use of the notebook, some times notebook would store some static charges which indeed will stop the notebook from powering up or charging the battery.
The procedure to remove this static charges from the notebook is known as power drain.
Performing a power drain procedure will not effect any personal data or delete any pictures from the hard drive on your notebook.

If issue persists, contact Notebook manufacturer for further support.

Hi,

There's a lot of causes why this has happened in your laptop. Here are some possible causes and solutions to this problem:

Since you bought a new laptop battery, probably it is good and your AC power adapter also, because you said that the power cord light remains on. I think what you mean for the power cord is that it is the AC power adapter.

First, try to power up your laptop through the new laptop battery that you recently bought if you believe it is holding a charge and make sure you don't plug in the AC power adapter into your laptop. But before you turn on the laptop, make sure that the contacts between your laptop battery and your laptop motherboard is making a good connection. Because sometimes it will not, maybe something spilled in there or there's some dust covering the contacts or some sort of dirt and they're not making a clean connection. To be sure that this is not happening to the contacts or your laptop battery and the motherboard of your laptop, pull the battery out, take a toothbrush and just scrub in between the pins of the battery there and also scrub down the the pins where the motherboard connection is (which is the contacts between the battery and your laptop motherboard, where you install the battery). If you are done doing this, put the battery in and turn the laptop on.

If the steps above doesn't solve your problem, try this one:

* Pull the battery out
* Remove main supply
* Hold power button down for 30 seconds. This will drain the charges in your battery.
* Put only power supply in
* Do not put battery in
* Turn laptop on
* Put the battery in

If you're done doing the steps above and did not solve your problem you can try the steps below:

You have to test if there's a fix voltage on your AC power adapter by using a voltmeter, usually 18 to 19V DC depending on the registered voltage written on your AC power adapter. If there is, kinda bend or jiggle the power cord a little bit to make sure the connections is tight. If the voltage remains steady, then probably your AC power adapter is good. Now we have come to the point that we need to deal with your laptop motherboard. There's a lot of reasons why your laptop won't power on even if you have a good laptop battery and AC power adapter. Maybe your laptop motherboard is partially bad, like for example if the dc jack on your laptop is bad and is not making a connection to the motherboard then it might look like the battery is bad as well because the battery is now now holding a charge or even taking a charge. Now this has happened a lot to plenty of laptop owners where their dc jack goes bad. They think their batteries gone bad because is not taking a charge anymore, they got and buy a new battery and then decide to bring their laptop to a laptop repair company because of the battery's not charging even with the new battery, that's because the dc jack is bad. You're going to probably right into this a lot where the battery's not charging because the dc jack is bad and until you fixed that, the battery's never going to charged. So how do you test if your dc jack is bad? It's simple, plug in the AC power adapter, take the battery out of the computer. If the computer doesn't power on then you know you have a problem with the dc jack. The only way to solve this, is that you have to disassemble your laptop, start taking components out one by one and finally, take the laptop motherboard out. Afte you've taken the motherboard out, look where the dc jack is connected. After you will find it, take a file tool and file off a spot on the motherboard where you can reattach the power jack and use a wire to reattach the power jack to the motherboard.

Hope you will find this answer helpful. God bless

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.

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!

Ac adapter does not connect to battery


You either have a faulty ac adapter; a bad power supply in your laptop; a bad battery; or a blown LED indicator light.
1. If the connection is not loose when you plug in your ac adapter try letting the laptop charge for a while. (If you are using the correct ac adapter)
2. Try removing your battery and using the ac adapter. If this works the battery is bad.
3. Try a new ac adapter.
4. Power supply is bad

Always using battery power


Try removing the battery and see if the laptop works with the AC adaptor. If not either the AC adaptor is bad or the motherboard is defective.

Battery


AC only will not effect speed what so ever, running on battery only does. Battery only decreases the speed, it's the speed step technology to make the battery last longer. If a fail safe in the battery engages, it could effect the machine's performance, so if you see any decrease in the performance, remove the bad battery and run without it.
