The touch pad on my Dell inspiron 15 3521 isn't working.
Hi I have a Dell inspiron 15 3521 and the touch pad is freezing. I have tried updating the drivers and the bios and when I run system diagnostics the touch pad works. But after putting the pc in sleep mode and then trying to use the touch pad it might work and it might not work. I can use a mouse and it works fine. I have also noticed that sometimes when it freezes the touch pad is missing from the device manager. Im not to good with this kind of stuff so any help would be great thanks.
