URGENT: My dell inspiron 15 5583 backspcae doesn't work correctly

This web page has a number of suggestions that may help. Among them try running in Safe Mode to see if the problem still persists. Also run an anti virus scan as that may be the source of the problem. Try an external keyboard to see if the problem still exists.

Hi @JOcean ,

Thanks for fast replaying and the useful link 

Ya I did all of this suggestions except  using external keyboard because I don't have for now. I'm using the built-in keyboard of the laptop

However, I tried  the on-screen keyboard of the windows and all goes correctly 

So Is this mean that it is a hardware issue?

Another think that I noticed when using keyboard tester

that when I pressed  backspace, the (+) key at numpad is pressed also .

check the snap 

When I disable numpad it doesn't work also ,The backspace behavior is being weird. It deletes a word at a time and when repeate pressing it delete every words at a time 

besides the mouse cursor is jumped everywhere  while typing  wherever ( on editor , notepad , on browser )

It make my crazy

All this weird behavior is disappeared when I pressed backspace + (+) key or backspace + shift key

And I thinks isn't right to do that every time I want delete char 

Thanks In advanced 

I do have the same problem with the same laptop if you found a solution share it
