Dim LCD on Inspiron 1501, Backlight or BIOS?

This question has suggested answer(s)

My Inspiron 1501 all of a sudden is showing a very dim LCD Screen. I can barely see it, so I have to use an external monitor. I ran the dignostics in the start up with <FN> and all test passed. I was told to increase the Brightness in the BIOS and, or Flash the BIOS and re-install the video driver. However, I can't find the proper instructions for these methods.  Does anyone know what I can do to see if it's the system before I go and spend money to see if its the backlight?

  • It's not the BIOS - the backlight or inverter is faulty.

  • I have the same problem.  I assume to fix this the backlight or inverter needs to be replaced, is this correct?  What is the cheapest method to do this?


  • Contact an LCD repair specialist shop.
