Does anyone know if the settings or specs of the two USB ports are different? When I plug in my external hard drive (samsung t3) to the right USB, everything seems fine, particularly, when I put the laptop to sleep, the hard drive shuts off. However, when I attach the hard drive to the left USB, and I put the laptop to sleep, the hard drive will shut down for a second, but then quickly boot back up. I left it like this overnight one time (before I realized this) and the hard drive was hot, having been on all night. I have also noticed that when my hard drive is connected to the left, there will occasionally be very brief moments of connection/disconnection. I have not noticed this connection/disconnection episodes with any other peripheral. Both ports charge my phone in while in sleep mode. Any ideas?
