Hi all,my touchpad suddenly not worked as normally but when i check in F12,the diagnostic didint found any problem,also all the Dell Touchpad application were missing..
Hi thanks for replying,my Dell is Dell Inspiron 15 (3521) and my Windows is Windows 10,i cannot see any application about touchpad,only HID Mouse (my wireless mouse) appear there.
Now, if Dell touchpad isn't listed in Programs & Features, I suggest you power off the system, remove all peripherals from system, remove wireless USB(mouse) receiver, AC adapter, and then battery. Press the 'Power On " button for 15 seconds to release Static Flea Power . Replace battery, adapter, and then power on system. Hopefully touchpad is working again. If yes, plug USB receiver back into system to see if touchpad still operate.
