Question about HEWLETT-PACKARD ProBook 4520s
You might have disabled the touchpad accidentally. If the touchpad is disabled it is indicated by a yellow LED on upper left corner of the touchpad and when the TouchPad is active, the light is off.
To turn the TouchPad on, quickly double-tap the TouchPad off indicator (the yello LED).
Hope it helps!
