Hi there and welcome
Can you tell me Bill, what exactly happens when you try to shut down the Laptop?
Remove the power cable and hold the power button for 60 seconds then release.
This should force it off.
Once off, power it on and tell me how it now operates Bill
It was the firmware that had an issue, and needed a hard restart. We did this just then. It will now be ok.
If you would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
