Legion T730 Output No Signal

2019-04-07, 15:14 PM

I am having some random issues with my T730 where when I first started to boot my PC, the monitor keeps saying no signal. I am using a display port to connect to my monitor. I tried to remove the cable and plug it back and the screen is still black. Meanwhile, my computer is on because I can see the LED color lights within my case. I had to completely force shut down my PC and turn it back on. Even so, not every single time will resolve the problem... sometime I have to force shut down again and turn it back on before my monitor detects a signal. Once I got back to windows, I checked the event viewer and it did not mention anything other than an error 41 about I rebooted my machine without properly shut down first.

 

Anyone got any idea as to what might be the problem? Video card? What steps should I follow to diagnose the issue? Thanks

Hi.

 

Just between the alternatives to solve this, I would suggest you to give it a try with a different HDMI or DP cable, and the video adapter. Try to find some other cable arround and check if you have a different result.

I am having the same issue. The PC is only a couple weeks old and just started having these same symptoms.

I am having the same issue.  I have Lenovo T730 with Nvidia GTX 2080.  I received my computer few days ago.  After using the computer between 30 mintues to few hours, the screen just goes blank with no signal sign.  Turning the monitor off and unplugging does not get the signal back.  I have to do hard power reset on the computer and the signal comes back.  Anyone having same issues?

No, it is not fixed. This is still happening randomly. I did update BIOS as suggested but that’s not the solution for sure to my problem. The problem is it only occurs randomly so is hard to catch.
