Hi all. I have a late 2009 Macbook White. I recently used an USB hub that (i think) it was faulty. My Macbook shut down without any warning... poof. Restarted fine but my 2 USB ports stopped working. I tried all this: - Used Apple Hardware Test. (no errors, all good). - Left it 30 minutes without power cord. - Booting Windows XP on bootcamp. - Boot with 10.6.1 disc to see if an external USB keyboard would work. - Boot in safe mode. - Create new Admin User. - Press and hold power button until led blinks on startup. - Resetting SMC. - Resetting PRAM and NVRAM. There was another thing to do: remove battery. Can`t do that because I don`t have the necessary screw driver (triangle thingie). Any extra help? Thanks in advance.
