The HP Envy x360 14 is a 2-in-1 convertible with USB-C and USB-A ports on its edges, and when a port does not work the most useful first question is whether the device or the port is at fault, since the convertible hinge and thin body mean ports see a lot of cable strain. Test the device on another port and on another computer. Try a different cable, because a charge-only cable carries no data and a worn one fails. Restart the laptop with the device unplugged and connect it after Windows loads.
The checks in more detail
Look in Device Manager under Universal Serial Bus controllers for a yellow triangle or an unknown device; uninstall it and restart so Windows reinstalls the driver. The x360 also folds into tent and tablet modes, and in these modes the cables on the ports may be pulled sideways, so a loose connector can drop out when you move the laptop. Check that the plug is fully seated and that the port is not damaged or full of lint, and clean it gently with a wooden toothpick with the laptop off.
If a USB-C port does not charge or display, test with another cable, since not every USB-C port carries video or power; the labels beside the ports show which do. For an external display, use a cable that supports video and try each port. Power saving can disconnect devices: in the power plan's advanced settings, set USB selective suspend to Disabled, and in Device Manager untick the power-saving option on each USB Root Hub. Install HP's chipset and USB drivers from HP Support Assistant and update the BIOS.
A bus-powered drive may need more power than a port gives on battery, so connect the charger. If a port fails with every device and cable, run HP PC Hardware Diagnostics by pressing F2 at start-up, and contact HP with the failure ID and serial number, as a damaged port is a repair. Keep a note of which port failed and under what conditions, such as after the laptop was folded, since the pattern helps the technician.
