Ok, im stupid. I tried this trick:
Basically it's a trick that allows you to charge a phonebattery with an old usb cable and a computers usb port. You cut it, peel it and stick the black to negative and red to positive on the battery, plug the usb in and it will charge. Problem is, i accidentally did reverse (black on +, red on -) and the computer died.
When i rebooted it, my usb ports are not working properly anymore. One is completely dead, the other one port still kinda works, but everytime a plug a device in, a message pops up that "it's drawing to much power etc.." and it takes 4 - 5 seconds, then the usb device is recognized. After this the device seems to work fine. I tried resetting SMC and PRAM, no difference.
Why is the message popping up everytime and is there a way to get rid of it? Since it's an old mac can live for now with one usb port (will never try tricks like this again for sure....)
My computer is a mid 2010 white unibody macbook, and i bought it through a company that buys old/broken/second hand computers, repairs them and sells them refurbished with warranty. Is it worth contacting them about this?
