HP Z420 graphics workstation: What causes a USB keyboard to lose power? The USB mouse is fine.

Thread Content

I would like to ask everyone: What causes a USB keyboard to stop working on an HP Z420 graphics workstation when the power is turned off? The USB mouse is fine. Installation system: Win7 64-bit English version, IA Series 9.0.119; the operating system is provided by FOXBORO.

It’s possible that the power output of the USB port is not sufficient, preventing the device from being powered on. Do not connect any other devices to the USB port when turning on the device; first connect the keyboard, and only after the keyboard is properly powered on should you connect other devices
