Inspiron 1721 Goes into sleep mode while typing

My Dell Inspiron 1721 has developed a really fun problem. While typing (on the left side of the keyboard) the computer goes into sleep mode. I went into the control panel and changed the settings so it never goes into sleep mode. So now it flashes to a black screen and the cycles back to the screen that I was on. Figuring that this had to be a keyboard problem I ordered and installed a new keyboard. No change! One suggestion was to disable in the Bios any setting that would put the computer into sleep mode. I did not  find any setting that would change the sleep mode. So that was no help. Anyone have any thoughts??

Hi Bear6201,

Welcome to the Community. Very strange issue, I would look at updating the Bios, you can use the below link to update it.

I also have the same problem with my N5110 laptop screen fading to black even while I am typing.  Sometimes it doesn't happen for days then it will occur 10 times in 15 minutes.  At t he suggestion of Dell Support  I have downloaded BIOS and Quickest, with neither fixing the problem.  Any suggestions before I initiate a formal service request?  PS The screen went black 5 times while typing this!  HELP !

I can fly with this model.
