Note: The steps provided in the link mainly works for Microsoft hardware but the steps can be applied to any wireless keyboard and mouse. Do not install any software given in the link as it will not help you if you do not have
a Microsoft Hardware.
It would be helpful if you could provide us the exact computer model number and also the make and model number of the keyboard and mouse.
Here's are a few troubleshooting steps you may give it a try.
1.If the underside of the mouse has an On/Off switch, set the switch to the On position.
2.Restart the computer. This can resolve the problem, at least temporarily, so that other troubleshooting steps can be applied.
3.Move the mouse or keyboard closer to the receiver. Make sure that the keyboard and the mouse are within 30 centimeters (1 foot) of the receiver.
If the receiver is attached to a cord, position the receiver so that it is on the same level surface, close to the mouse and keyboard.
4.Replace the batteries with a fresh set of alkaline batteries and make sure they are correctly installed. If the mouse or keyboard is not
working, replace the batteries even if the mouse/keyboard software indicate the batteries still have a charge.
Remove the battery cover to access the batteries. For keyboards, the battery access cover is found on the underside of the keyboard. When replacing the batteries look for the positive symbol (a plus sign +) imprinted near the
battery compartment or battery cover. Make sure the positive end of the battery is oriented to the positive side of the compartment.
5.If you have a USB receiver, unplug the USB receiver, wait 10 seconds, and then insert it into another USB port - preferably into a USB port
that is closer to the mouse and keyboard. For example, if the USB receiver was plugged into a USB port on the back of the computer, unplug it and plug it into a front USB port.
6.Re-sync the wireless keyboard and mouse connections.
7.If keyboard error messages display, remove old keyboard software before the keyboard can be used. To do this open Control Panel, Uninstall
a program, and remove any item in the list that relates to a keyboard. You can install any new keyboard software after the computer is restarted and the new keyboard is recognized by Windows.
8.Check the status of the keyboard and mouse in Device Manager.
Open Device Manager:
Move the cursor to the lower left corner of the Start screen and right-click. Select Device Manager in from the menu.
After opening Device Manager: Click the plus sign (+) next to
Keyboards or Mice and other pointing devices. Right-click the name of the keyboard or mouse, and then click
