PC doesn't see my z5

[BigOs]

A couple of weeks ago I had no problems with my pc seeing my z5, now it won't. When i connect it via usb the phone chimes and comes up with the usb options but nothing. Companion doesn't see it either. Been into Device Manager and that says that the device is incomplete / damaged. Tried deleting the driver and reloading the latest from sony but that says there's a problem with the INF = invalid. The phone has been playing up lately - going into airplane mode / do not disturb turning on at odd times / volume[s] turning off unexpectedly. Any help would be appreciated.

Hi,

My Z5 used to connect ok but since changing my laptop it no longer connects or charges via USB.  It makes a 'ding' noise when it's plugged in but nothing comes up on my device or on my computer.  I have gone through a lot of solutions including forum responses and Sony help but none of them have worked.  I have tried multiple USB ports and cables (I dont have another laptop/PC that I can try).  I have cleared the Media Storage data.  My device claims that it has the latest updates installed,

My Z5 does not show in Device Manager when connected, it doesnt prompt a USB mode on the device, Xperia Companion cant see it and neither can Windows Explorer.

I also have an XZ1, this works with my laptop and Xperia Companion.

I have reinstalled the latest Z5 driver from Sony but this hasnt worked.  This process has been going for a while and both the laptop and device have been restarted many times.

It seems to me that it's a driver issue, but I'm not sure how I resolve that, especially given that I cant see the device in Device Manager?

Thanks,

Andrew.
