I would get some type of cloth and rub and rub and rub the connectors until they are golden again and give it a try.  Most people will probably tell you to get a new one, but since I like to tinker, that's what I'd be doing with mine.

MacBook Pro is slow when disconnected with electric charging.


First step would be to Reset Your Mac's SMC
The method for resetting your Mac's SMC depends on the type of Mac you have. All SMC reset instructions require shutting down your Mac first. If your Mac fails to shut down, try pressing and holding the power button until the Mac shuts down, which usually takes 10 seconds or so.

Mac portables with user-removable batteries (MacBook and most MacBook Pros):

1.Shut down your Mac.
2.Disconnect your Mac portable from its MagSafe connector.
3.Remove the battery.
4.Press and hold the power button for at least 5 seconds.
5.Release the power button.
6.Re-install the battery.
7.Reconnect the MagSafe connector.
8.Turn your Mac on.
Mac portables with non-user-removable batteries (MacBook Air and some late 2009 MacBook Pro models):

1.Shut down your Mac.
2.Connect the MagSafe power adapter to your Mac and to a power outlet.
3.On the built-in keyboard (this will not work from an external keyboard), simultaneously press and hold the left shift, control, and option keys while you press the power button. Release all keys at the same time.
4.Press the power button to start your Mac.

Mac desktops (Mac Pro, iMac, Mac mini):

1.Shut down your Mac.
2.Unplug your Mac's power cord.
3.Press and hold the Mac's power button for 15 seconds.
4.Release the power button.
5.Reconnect your Mac's power cord.
6.Wait five seconds.
7.Start your Mac by pressing the power button.

Alternative SMC reset for Mac Pro:

If you have a Mac Pro that isn't responding to the normal SMC reset as described above, you can force a manual SMC reset by using the SMC reset button located on the Mac Pro's motherboard.

1.Shut down your Mac.
2.Unplug the Mac's power cord.
3.Open the Mac Pro's side access panel.
4.Just below the Drive 4 sled and adjacent to the top PCI-e slot is a small button labeled SMC. Press and hold this button for 10 seconds.
5.Close the Mac Pro's side door.
6.Reconnect your Mac's power cord.
7.Wait five seconds.
8.Start your Mac by pressing the power button.
Now that you have reset the SMC on your Mac, it should be back to operating as you expect. If the SMC reset didn't fix your problems, you can try combining it with a PRAM reset. Although the PRAM works differently than the SMC, it can, depending on your Mac model, store a few bits of information that the SMC uses.

Computer will not turn on even with power cord


1. Disconnect any devices connected to the computer including printers, hubs, and third-party keyboards or mice, and test the computer again by trying to turn it on.
2. Find out whether the battery on your Apple portable has power. Press the small button on the side or bottom of the computer, depending on the model. Lights should indicate the battery's level of charge. A single blinking light means the battery needs to be recharged. Connect the adapter to recharge the battery.
3. Unplug the power adapter from the electrical outlet and from the MacBook Pro. Wait one minute. Plug it back into the wall first, then to the computer. Make sure the electrical outlet is working by plugging in another device (such as a lamp). When you plug the adapter back into the computer, the power adapter LED should light up green or amber. If the light does not come on or the computer continues to not power on, proceed to step four.
4. Inspect your MagSafe power adapter. See Apple Portables: Troubleshooting MagSafe adapters for instructions on cleaning the adapter and more details for these steps:
  • Check the MagSafe connector on the adapter for any bent or damaged pins, debris, or alignment issues with the connector.
  • Check the MagSafe connector on the computer for any debris, damaged pins, or alignment issues.
  • Check the MagSafe adapters cabling for any wear or cable issues.
5. Make sure you are using the adapter that was designed for your computer. If you aren't sure or if you need a different adapter, learn which adapter is appropriate for your computer.
6. Review the steps for resetting the SMC (System Management Controller) on your Apple portable computer.
7. If you recently installed additional memory or a hard drive not made by Apple, make sure it is installed correctly and is compatible with your computer.
8. If you are still unable to start up your computer after trying each of these steps, schedule a service appointment with an Apple Retail Store or an Apple Authorized Service Provider.

Hi,

Follow the steps below and it should solve your mac problem..

  1. Disconnect any devices connected to the computer including printers, hubs, and third-party keyboards or mice, and test the computer again by trying to turn it on.
  2. If you're using a MacBook or MacBook Pro, check the battery level. Press the small button on the battery or on the side of the computer. You should see lights indicating the battery's level of charge. If you see just one light blinking, the battery needs to be recharged.

Make sure the electrical outlet is working by plugging in another device (such as a lamp). When you plug the adapter back into the computer, the PowerBook G4 Battery 15" power adapter LEDs should light up green or amber.
  4. Inspect the MagSafe port on the computer for debris, such as metal stuck to the magnet in the port, which might prevent the connector from seating properly. On the adapter side, look at the DC connector for dust or other debris and check whether pins are missing, bent, or stuck down. If you find any of these to be true, see Apple Portables: Troubleshooting MagSafe adapters for instructions on cleaning the adapter.
  5. Make sure you are using the adapter that was designed for your computer. If you aren't sure or if you need a new adapter,learn which adapter is appropriate for your computer.
  6. Press the control key, the command key, and the sony vgp-bps13a/b battery power button simultaneously and hold for three seconds to try to restart the computer.
  7. Reset the PRAM. After pressing the power button, hold down these keys simultaneously: Command-Option-P-R, until you hear the startup chime at least one additional time after the initial startup chime.
  8. Reset the SMC for the MacBook And MacBook Pro by removing the AC power, removing the sony vgp-bps13 battery and then holding down the power button for five seconds. On the MacBook Air, press (left) Shift-Control-Option along with the power button once. Note: You must use the keys on the left side of the MacBook Air keyboard.
  9. If you recently installed additional memory, make sure it is correctly installed and is compatible with your computer. Remove the new memory to see if the computer starts up properly without it.
  10. If you are still unable to start up your computer after trying each of these steps, schedule a service appointment with either an Apple Retail Store or an Apple Authorized Service Provider.

MacBook Air 11" won't power


1. Verify AC power presence with MagSafe LED indicating on or charge state.
2. Verify battery as being partly charged, with orange/amber LED on MagSafe power connector.
3. Reset SMC
Resetting the System Management Controller (SMC) The System Management Controller (SMC) is a chip on the logic board that controls all power functions. If the computer is experiencing any power issue, such as not starting up, not displaying video, sleep issues, or fan noise issues, resetting SMC may resolve it. To reset SMC: 1. If computer is on, turn it off by choosing Shut Down from the Apple menu. 2. Connect power adapter to computer and to a working power source. 3. On built-in keyboard, press (left-side) Shift-Control-Option along with power button just once. Important: Use Shift-Control-Option keys on left side of keyboard. Note: When the LED on the MagSafe connector is orange/amber, resetting the SMC will change it to green for a few seconds, indicating that SMC was correctly reset. 4. Wait 5 seconds and press power button to start computer. Note: If bottom case is removed, you can alternately reset SMC by disconnecting both power adapter and main battery, and holding down power button for 5 seconds.

Power Adapter Issues 1. Connect AC adapter's MagSafe connector to the computer. The LED on the connector should be green or orange/amber. 2. Verify power cord or duckhead is firmly attached to AC adapter. Check that duckhead is not damaged. 3. Verify AC power source is supplying AC power. 4. Check for dirty or stuck pins on the MagSafe connectors, both on the adapter and the computer. 5. Reset SMC by pressing the (left) Shift-ControlOption(Alt) keys along with the power button once.

    My MacBook don't start. Is the power button? Is any password to solve this?


    A password would not prevent your Macbook from starting, so I don't think that is the issue.

    There are several variables to consider when it comes to power issues with an Apple Macbook.
    For one, is your battery charged where you can test it without the MagSafe adapter, to see if the Macbook will start up?
    • Also, is the MagSafe Adapter itself, not frayed or damaged, is free of debris and is able to connect securely to your Macbook?

    If you have checked both of these sources for powering up your Macbook and you still cannot turn your Macbook on, then that is a hardware issue.

    Sources of hardware issues with your model of Apple portable notebooks are:
    * The Power supply: (source of power to the main logic board in the Macbook, and connects to the MagSafe port which of course connects the MagSafe adapter into a external power source - i.e: "a wall power socket")

    * The Main Logic board: the main board in your Macbook which contains all processors, RAM, audio & video ports, ethernet, USB and other ports and components-including the Power Supply.

    * RAM- If your RAM (Memory) goes bad, this can also impact the start up of your Macbook
    ---------------------------------------------------------------------
    A good way to test and see if you can start your Macbook up is to try this procedure below:

    -SMC RESET-
    The System Management Controller 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.
    • Disconnect the AC adapter and remove the
    computer's battery.

    • Press and hold the power button for 5 seconds
    and then release the button.

    • Reconnect the battery and AC Adapter.

    • Press the power button to restart the computer

    **IF you cannot get you Macbook powered up using this SMC Reset, that means you will need to take your Macbook in to your local Apple retail store Genius bar or Apple-authorized service center to have a diagnostics performed on your Macbook.

    I am sure this will help guide you in the right direction toward address this issue.
    Let me know if you have more questions regarding this issue.

    Thanks!
