I recently upgraded my Windows 7 Pro system to Windows 10 and now experience a problem. The system has a KVM switch that showed no problems with Windows 7. Windows 10 saw my monitor, keyboard and mouse on installation and everything works fine. However, frequently when I wake up the computer after it is in sleep mode, the monitor does not come on and the keyboard is locked. This seems to happen if I accidentally double click the keyboard or move the mouse. The only solution is to turn of computer off and then back on. Windows starts where I left off before entering sleep mode.

Hi Mimas123,
What is the exact machine model?
Since the issue occurred after we upgraded to Windows 10, I suspect there may be a compatibility issue. Please ensure the device manufacturer website has released Windows 10 compatible drivers for your machine model and KVM switch has windows 10 compatible drivers, too.
If you have got Windows 10 drivers, we could try to run "powercfg -devicequery wake_armed" to lists devices that are currently configured to wake the computer from any sleep state.
Use "powercfg -deviceenablewake "device name"" to configure the device to wake up the machine.
Of course, we could try to run the built-in "Power" troubleshoot to have a diagnostic.

Is it a self powered or unpowered switch?

I am having the same problem. When my desktop goes to sleep, tapping the power button returns from sleep however the monitor does not get a signal from the desktop.
- My KVM is unpowered
- Desktop is connected as device 1 (Ctrl+Alt+1)
- My laptop has a dock that is always connected to the KVM as device 2 (Ctrl+Alt+2). Toggling back and forth between desktop (black screen with no signal) and laptop works just fine.
- Machine model is Gateway SX2800
