USB Connector problem on Dell Latitude 6540

Hello

I have a laptop dell Laltitude E6540 and there's a problem with the two USB connector on the right of the laptop.

When you plug a hard drive, sometime is disconnected, you don't know why... 

It's like there's a problem with the connector.

if you move the laptop, you have more chance to have a disconnection.

The USB of the left works fine.

Is it a known problem ? 

The laptop has less than 6 months.

Thanks
