Might anyone with a 13in. late 2013 rMBP (Haswell) please check your console for the following error message:

kernel[0]: The USB device Apple Internal Keyboard / Trackpad (Port 5 of Hub at 0x14000000) may have caused a wake by issuing a remote wakeup (2)

You will have to remove ANY USB device plugged in to a USB port as the error will not show with a device connected.

Many thanks for any responses!
