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 power supply


Openand look at power supply board for capacitors which are "balooning" or deformed in any way. These look like cylindars on the board. These tend to dry out and make what you are describing occur. Replacing them usually fixes about 80% of the problem you are describing. Those parts run about $0.25 to $0.75 each.. well worth trying, right?

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.

Lap top won't come on


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. Use the fluorescent pen computer with the adapter connected to recharge the battery.
  3. Unplug the power adapter from the electrical outlet and from the MacBook, MacBook Air, or 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 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.
Regards,
Ron

Keypad not responding upon start up


Hello and thank you for visiting Fixya Support, I will be glad to assist you.

Here is a process I would recommend you try to resolve the issue with your Macbook Pro's keypad not responding.


-SMC RESET-
The System Management Controller is an integrated circuit (computer chip) that is usually on the logic board of your Mac portable.

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.

Shut down the computer.
• Disconnect the MagSafe power adapter from the computer, if it's connected.
• Remove the battery.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Reconnect the battery and MagSafe power adapter.
• Press the power button to turn on the computer.

Let me know if this helps.
