Today, I closed the lid of my white macbook so it went to sleep. I then found my new i-pod nano and plugged it into the USB port. My i-pod began to charge, it said 'eject before disconnect'. Then some minutes later, I opened the macbook and tried to use it. However, it did not wake up from sleep.... I had to hold the power button down so it forced turn off... Does this happen with everyone? Seems a bit unusual... I hit many keys but it didn't wake up.
