If “mouse not working” repeats, it is better to narrow it down to USB/Bluetooth connection, sensor, or battery rather than changing several settings at once. Divide the problem into the mouse hardware and PC side by testing sensors, batteries, wireless connections, and other ports.
When troubleshooting no keyboard input at all, it is important to rule out the causes one at a time. Based on the “Keyboard not working” symptom, check the USB/Bluetooth connection and driver and proceed to the next step. Compare with other ports and other PCs to distinguish between problems with the keyboard itself and problems with Windows input settings and drivers.
