However, you do not necessarily have to try all these solutions. You can begin troubleshooting with the first fix and stop when the problem disappears.

Fix 1: Check the keyboard/mouse connection and reset the device

Hence, check the battery level and charge the battery of your keyboard or mouse if it is low. If the batteries keep disconnecting or turning off, consider replacing them with new ones.

Moreover, ensure the lock button on your keyboard is turned off. To turn off the lock button, press the button with an imprinted lock icon.
