Start by turning off all of the connected computers and peripherals, unplugging everything from the KVM, including power, and leaving it for 10 seconds. No matter how we use it, it does support a number of servers to connect to the same set of consoles, saving us desk space and a good number of hardware costs. For instance, when you try to handshake with your monitor, your graphics driver can just give up after a while. How to power cycle: Unplug everything. We also make a KVM switch troubleshooting video to help you diagnose problems and fix them. Problem 1: The KVM. It doesn't always happen, but when it does, a complete restart is required. Even if I add a second mouse, completely seperate from the Logitch Keyboard and Mouse, it ALSO will not. What appears to be happening is that the KVM will randomly shut down, and the only way to turn it back on is to either unplug/replug the power cable on the KVM side or to do the same to the power brick. The KVM's been plugged into a Cyberpower UPS for as long as I've had it so it's not like it got. Does anyone have a problem using kvm or usb switch? I also tried directly connecting the keyboard/mouse then plug and unplug multiple times but still the keyboard/mouse would stop working. The keyboard/mouse is still detected in device manager.
