First: Sorry for my bad english. I'm german. :D

My G751JT always reconnects the USB Ports when I plug in or plug off the power supply.

So when I watch a movie from a external USB HDD the movie stops with an error message and I have to click "Play" again.

I have the problem with a 2,5" USB HDD without a external power supply and with a 3,5" USB HDD with external power supply.



I changed the usb settings in the boot menu. Nothing changed.

I changed the energy saving options for the USB ports. Also nothing.

I'm using Windows 10.


I found no posts regarding this problem.

I hope I find some help here. Thank you. :)

Does the problem occur with USB Flash Drives as well? Did you try using the USB Ports on the right side?

Thanks for your quick answer.

I figured out that only one usb port is having this problem. Its the first usb port after the three audio connectors on the right side.

When I use a USB Flash Drive all 4 usb ports are working fine.

Do you have any guess why this one port is causing trouble? :D

You could try reinstalling the ASUS USB Charger Plus, it may cause trouble. I tested USB ports on the right side with a USB 2.0 HDD, they are working fine when I disconnect/reconnect charger. The USB ports on the left disconnect constantly on my G751JY, because the HDD doesn't get enough power.

One thing I noted is the USB cable itself. I was having issues with a 2TB USB 3.0 drive just dropping out randomly. I changed drives, got the same problem. I was pulling my hair out and tried everything but still it would just drop off then come back randomly. could be during data transfer or while watching a moive etc. Finally I just swapped out the cable and no more problems. It was a new cable too but hey, everything is made in China these days and QC is not at the top of their priorities.

You are the best. :D
