I was away for the weekend. Used HP laptop to upload and process photos, and connected using mobile hotspot, as no Wifi. Had difficut doing this, so another tried bluetooth. Got the photos up loaded, but wireless USB mouse stopped working, and now both USB ports and SC card port not working.
Have read some tutorials about the mouse which didn't work, but it is the USB ports.
Any help much appreciated. The laptop is only about two months old, so still under warranty, but it might something I did, I suppose.
Remembered that I had changed default browser to Firefox, and changed some defults, so went back and changed to Edge, remembering that M$ doesn't like us using other software. I'll still use Firefow, just won't change the deafults :-)
