USB Over Current Notice
My daughter's MacBook Intel Core Duo had been connected to a BookEndz for two years. Through the connection, she had been using an external LCD monitor. She upgraded the unit to Mac 10.5.6 one month ago. Recently, the unit displays a warning box each time when it boots up. The warning says USB Over Current Notice. A USB device is currently drawing too much power. The hub is is attach to will be deactivated. This warning notice appears even without a connection any USB device or the Bookendz. She used the Hardware Test program and found everything was normal. We tried reset the system power management(?) to no avail. She tried reinstall Mac OS 10.5.6 and Mac OS 10.4.6 to no avail. Also, the two USB ports are not working at all. I assume that they are deactivated as the warning notice says. What is wrong with the MacBook? What should we do to correct it?
I appreciate your advice very much. Wishing you a happy new year.
