G470 Display with extreme low brightness

Hi!

I'm having this problem.. mi G470 is showing video without almost any bright. I thought that the LED display was wrong so I replaced it, but the problem persists. Somewhere I read that there is a fuse on the motherboard that gives power to the display. Is this correct? Does anyone knows anything about this? 

(Windows starts normally, ?I can even login...)

Any clue will help! Thanks!!

Re: G470 Display with extreme low brightness

Hello Jvidalcastilla

Thanks for using the Lenovo forums.


Does this issue persists in the BIOS menus?

 

If so, it will be a hardware issue.

If not, then try a factory reset, this will rule out any software issues.

 

Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

Hope this helps, let us know how you get on.
