I have a problem that is similar to the one described a long time ago in this question: My HP Elitebook 850 G3 suddenly (from one day to the next) doesn't seem to show anything on its display. Only a bit later I found out that it does indeed show the display contents, but that the backlight wasn't working.
Strangely enough, when pressing the fn
-key and then simultaneously the break
-key (which happens to be the right shift
-key in combination with the fn
-key, the backlight is turned on and stays on, as long as the break
-key is being pressed (the fn
-key can be released).
When the break
-key is released, the backlight turns itself off. Completely.
Some more things to note:
- The longer the
break
-key is pressed, the longer it takes for the backlight to turn itself off when thebreak
-key is eventually released - almost 1:1 in terms of duration. - This is not Windows related, as the same behaviour is present within the BIOS setup
- Loading the factory defaults in the BIOS setup didn't change anything
