Keyboard locked keyboard and mouse not responding

hi there!

since you only disconnected the printer from the pc, it shouldnt have any effect on the other things connected to the pc. try to powercycle pc, turn off, shutdown, unplug power cord from wall outlet, leave it like that for 2mins. plug it back in, turn on. check mouse light and keyboard lights (caps lock, num lock lights) if none of these responds, check the drivers (device manager) if they have bangs (!), if yes, reinstall their drivers. =)

Hello There! Check if "Num Lock" is on. Otherwise go on Control panel and click on Keyboard settings. Reset the driver.
I wish I helped you & that this helped you at most! Don't forget to rate & all the best! ;)

Can you give me more information...What brand of mouse and keyboard are they?

Do they use seperated recievers or does one reciever work for both mouse and keyboard?

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

make sure there is new batteries in both the mouse and keyboard. Also the wireless receiever that connects to the computer is responding as well.

After you get new batteries put in and also have the receiever plugged in. press the caps lock, num lock keys and see if they light up on the receiver. If they light up then things are working, if they don't then bring up the notepad and see if any of the keys show up in notepad when you type and also see if the cursor on the screen moves for your mouse.

Hopefully both of them will work once you change batteries. If both don't work after changing batteries then you'll need to get a new wireless keyboard/mouse kit.

open the Logitech utility and try to reconnect the keyboard and pair it with the mouse. if it doesnt work uninstall/reinstall the software for your wireless mouse/keyboard.

Have you tried a USB keyboard and mouse wired.try also to hook up the normal keyboard and Mouse with out any usb devices hooked on the computer

Make sure batteries are good in both the Keyboard and Mouse. Then press the button on the Receiver.
Normal 0 Press the Receiver button (and the lights will start flashing.
Then if the Keyboard isn't working, press the small RESET/CONNECT button on the back of the board to connect the keyboard to the receiver.

If the MOUSE isn’t working, push the small RESET/CONNECT button on the back of the mouse to connect to the receiver. Then they should work okay.
Hope this helps. Bud

could be the mouse, could be the computer... Have you rebooted, changed the batteries? Click the reconnect on the bottom of the receiver, and then on the bottom of the mouse, repeating for the keyboard?

if its laptop there is a button that locks the keyboard and mouse just look for the sign that locks and unlocks the keyboard and mouse.

I don't know if this would help however I had a problem with my keyboard earlier today. What I did was restore my computer to an earlier date. In my case I restore it to yesterday date and it worked.
