I'm having the following issues with my nearly 4 year old Z50-70 since last week:
After turning on the notebook and Win 10 login, USB 3.0 port doesn't recognize my Huawei 4G router (no such problems before). The 4G device is under charge, but is not recognized. If I re-plug it to any other USB port, it's only being charged, but still not recognized.
USB mouse is working after startup, but if I plug it out, then plug it in again to any port, it's not getting recognized anymore, it only gets power supply via USB.
My external HDD is also not recognized.
If I hit a Windows restart, it takes several minutes for the notebook to reload the system (this is something new as well...), but every USB device will be working fine after the restart. But if I close the PC by shut down, none of the USB ports will work after startup.
Any help and idea would be appreciated, thanks in advance!
