hi guys
i hope im posting in the right section.if im not please advise me were to post it.
a good friend asked me to have a look at her dell inspiron 3520 laptop because the Touchpad and the right + left Buttons Stopped Working.
so i opened up the dell touchpad configuration utility to check everything was ok and set it to default.
in-stalled and re-installed the touchpad driver.
nothing works except the left tap on the touchpad...not the button.
i was going to do a factory reset just to rule out hardware problems. but i need to talk to her first.
any ideas??

Go into the BIOS and see if the buttons work there. If they do, then you know it's an issue within Windows. If they don't work, it's a hardware issue.

✔ Best Answer
I wonder if the scroll pad had been disabled via the Fn+F3 keys - though it wouldn't partially work, as you described.

Plug in a USB mouse. If this works, WIndows is ok - it's a hardware issue.

If so, it could be the ribbon cable attaching the laptop scroll pad to the motherboard has worked loose. However the laptop has to be stripped down to check this.
