IdeaPad Z710 USB 3.0

I bought an IdeaPad z710 laptop in August 2014.  I have been trying to add a new Seagate Slim Backup Plus 2. TB USB 3.0 hard drive.  I do believe that the Z710 has two USB 3.0 ports. I am trying to connect it at the same time as my SIIG 4 port USB 3.0 "powered" hub, on a different USB 3.0, but the hard drive keeps connecting / disconnecting.

 

Would this be normal?

Welcome to the forum !

 

Yes, your model does have two USB 2.0 and two USB 3.0 ports. 

 

Does the Seagate drive connect without SIIG powered hub being attached ?  If it stays connected when the SIIG isn't attached then I would suspect that when both devices are attached to the laptop that the USB 3 circuit doesn't have enough power to power both.   You'd be better off connecting the Seagate to the powered hub.

I was trying to connect the SIIG hub and the Seagate hard drive onto each of the USB 3.0 ports.  Yes, the Seagate "behaves" when it is only connected.

I still think the USB 3.0 ports doesn't have enough power to run both devices.  What I would try next is plugging one of the devices into a USB 2.0 port and the other into a USB 3.0 port. These two different style USB ports may have their own separate power circuit.  If that doesn't work then you may just have to plug the Seagate into the hub for use.
