Right side USB has stopped detecting any devices
Today I took my MacBook Pro Retina (late 2012) for repair. It had speaker problems, which the technician has solved but since returning home I am facing few issues:
- Right side USB has stopped detecting any devices what so ever.
- There is no more startup chime (bong sound) even when I shut down completely and start again. This is the most strange part.
I am doubting if the technician has messed it up somehow or is it just that he simply forgot to connect one of the cable/wire and if it's not those issues is there any chance that he he has messed up the I/O board which is on the right side where the right side USB is? Everything else seems to work fine (camera, wifi, bluetooth, left USB port, Power connector etc.) But I haven't until tried the other right side ports that includes HDMI and SD card reader as I do not have those devices. Any ideas?
Things I have tried to no avail:
P.S. This MacBook pro is out of warranty so I can not take it to apple.
There IS sound coming from both the speakers and headphones,
The problem I found as of now is with the RIGHT side USB port as it isn't detecting any devices whatsoever.
The second strange thing I have found is there is NO boot sound the (bong sound) it used to make before I don't know why it doesn't make that sound anymore not that I need that sound but is it a sign to some fault?
Ist dies eine gute Frage?
