Idea Pad Y580 display backlight is not working

Hi Everyone!


My display backlights stopped working. I'm still able to see what is on the screen when i put my cellphone flashlight on the screen but it's really hard to see anything. From what I read online it might be just a fuse or the display itself. I was not able to locate the fuse on the motherboard, if someone can help me find the fuse would be great. At first I was thinking of ordering the display but some people changed the display and the problem was still there. Any advise would be appresiated.

P.S. The laptop is already completly dissasembled Smiley Happy

Hi, Ventsy                   -


Thank you for writing in to the Lenovo Forum - happy to have you here today.


There were a couple of expert opinions;

  1. it's your inverter (hardware problem)-based on the fact that the screen brightness faded suddenly (but didn’t disappear) and that the screen was not bright on a reboot from before the login screen
  2. it’s a software problem- for which the solution was back everything up and do a reinstall

Kindly contact Lenovo service centres for hardware assistance.
