Solve problems with your wireless keyboard and mouse

If your keyboard or mouse works on disposable batteries, then these will be empty at some point. Put new batteries in the peripheral to check if this solves your problems. Does your keyboard or mouse have an integrated battery? Put in the charging cable and connect it to the PC. If an empty battery was indeed the problem, this step will solve it and your keyboard should do exactly what you want again.

It might be the case that the dongle of your keyboard or mouse isn't working properly if it's inserted in a gray or black USB 2.0 port. Always try if the keyboard or mouse do work properly if you put the dongle in a USB 3.0 port. These ports are usually blue. Make sure the dongle is inserted in the port closest to the keyboard or the mouse. That way, it's more likely that the peripheral picks up the signal well.

If there are devices nearby that use a 2.4Ghz band, this can disrupt the wireless signal of your keyboard or mouse. These can be appliances like a microwave, mouse, or telephone base station, for example. Try setting up your work space in a different location in the house or make sure your other devices with a 2.4Ghz signal are turned off.
