View Full Version : USB keyboard not working after waking up.

I don't know since when I've been facing this problem but it has become frequent. My login screen is password protected so when I wake up from sleep, the USB keyboard doesn't work, so I can't login and I have to reset. Even on pressing reset button on CPU chassis, the USB keyboard remains unresponsive, I have to connect a PS/2 keyboard and fiddle(just disable and re-enable) with USB settings in BIOS to get the USB keyboard working again.

The keyboard is connected to a USB Hub(which is connected to a USB 3.0 port at back). The reason for this is USB keyboard doesn't word when connected directly to the motherboard's USB port at back. But that same port which doesn't work with USB keyboard and WiFi adapter works with other USB devices.

Is there a way to resolve this?
