- the sensor is disabled in the settings;
- system utilities are obsolete and need to be updated.
Turning on the touchpad
Oddly enough, the trouble is often eliminated by the banal activation of the touch panel. To turn on the touchpad, just hold down the Fn button on the keyboard, and then add the system key to the combination. Her role can play F1, F7, F12. It all depends on the model and manufacturer of the laptop. In some cases, turning off the mouse helps. The solution makes it possible to eliminate the conflict of devices for controlling the cursor.
Some laptop manufacturers bring the power key directly to the sensor. Usually the specified button is located at the top of the panel on the left. In order to enable the touchpad, briefly press the key several times.
