Q: macbook pro does not power up after usb phone charrged

Hello bobconner2

What troubleshooting have you done from the article that you came from? I would suggest starting with resetting the SMC on your MacBook Pro as well as checking to make sure that your power adapter is working properly.

Resolution

If your computer won't turn on, try each of these steps:

1. Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
2. If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter. 
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
3. Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
4. If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only). Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).
