Re: MBA USB port not working
When USB port is not working, there may be several reasons (or no reason) for USB ports ceasing to function with no cause. How to resolve MBA USB port problem SMC RESET For those with a MacBook, MacBook Pro, and MacBook Air, all you need to do is this: Shut down the Mac and connect the power cable Hold down Shift+Control+Option+Power concurrently for a few seconds, when the light on the power adapter blinks or changes colors you’ll know SMC reset is complete Release all keys at the same time Boot the MacBook Pro / Air by hitting the power button as is typical The USB ports on the MacBook should now work just fine, which you can confirm by connecting the USB device as usual and checking to be sure that it works – PRAM RESET Shut down the computer. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step Turn on the computer. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears. Hold the keys down until the computer restarts and you hear the startup sound for the second time. Release the keys. Other Considerations for USB Not Working on a Mac If a single USB port has failed but other USB ports are continuing to work on the Mac, If some USB devices work on the Mac, but another USB device does not work If there are firmware and OS X software updates available, install them onto the Mac. |
