I think this is not an hardware issue, it's an OS setting. You don't need to make BIOS changes. I think you can solve this in 2 steps:
Go to Control Panel > Power Options > Change Settings Scheme > Change Advanced Power Settings > USB Settings > and deactivate Selective Suspension;
Go to Control Panel > Power Options > Choose What Power Buttons Do > Activate Settings Currentlly Unavailable > scroll down to Shutdown Settings > disable Activate Fast Start.
That should solve your problem. It did for me ;-)
