I am having a serious problem on my dell inspiron 3542. whenever i click refresh on the desktop it refreshes but the top left icon gets clicked always. and when i hover the mouse cursor over the icons it immediately gives the information about it even though when normal it takes some time to give information. Also, whenever i type number 8 from the numpad the mouse cursor shifts automatically to extreme left of that sentence or word. also when i scroll from top to bottom, it won't let me scroll down.
I even reset the laptop but i kept the personal files and installed windows again. But it didn't solve the problem.
Please help me fast. I am experiencing this problem from the past 4 days. I am running Windows 10 Pro build 1703 64bit with all latest updates and 4GB ram core i5 4210u.
I am using the Synaptics touchpad with the latest drivers.
But DELL has tested this laptop running of Windows 10 on it. But when I go to drivers and downloads section, I don't see Windows 10 drivers. Also, in June 2017, when I visited the drivers page, it was saying that they have Windows 10 64- bit drivers available for this laptop.
This system supports up to Windows 8.1 from Dell - that doesn't mean it won't run 10, but it does mean you will need to get the drivers from ALPS or Synaptics -- whichever touchpad you have.
