Backlight not coming back on

The laptop just returned from the lab for another issue and after a system restore, from a backup made just before sending it to the lab, I discovered this new issue that was not present before.
Every once few hours, sometimes minutes, the keys backlight wont turn back on when moving the mouse or clicking a key as it should, I then have to click the backlight fn key for it to turn back on, and then it will turn back off after a few seconds of inactivity and back on again normally for a while, untill it randomly won't turn back on on a keystroke or mouse movement and I'll have to click the backlight key again to "start it up". It doesnt matter on what level the backlight is left on, it eventually stops turning back on any of the levels.
Do you think this is software related or hardware? The issue was not present before the I sent it to the lab
Is there any diagnostic I can run to see if it hardware related? or a driver that might solve this?
