The problem is solved with a UPS, the air conditioner that is have caused the problem, when the fan start working it suck so much current and cause the black screen to appear, and now with the monitor plugged into the UPS it work perfectly even the air conditioner is on.

Hello @Mehdi00124,

 

Welcome to the Community Forums.

 

I would suggest trying to update the display drivers of the machine if you haven't already.

You can download it using this link (please note that you may have to enter your serial number in order to get the right file): https://pcsupport.lenovo.com/uk/en/products/laptops-and-netbooks/ideapad-s-series-netbooks/s540-13iml/downloads/driver-list/component?name=Graphics%20Processing%20Units%20%28GPU%29%20and%20Server-AI%20Accelerators


Hope this helps.
Regards,
Jack_Lenovo1

Hi thanks for your reply, i updated both of the display drivers and i still have the same problem, i don't think it's my laptop problem i had a Philips monitor before i get this one and i never got this problem with it before, this is my laptop specs anyway : S540-15IWL GTX (I5 8265U GTX 1650 max Q)

I also tried this monitor under Ubunto same problem, i hope someone from Lenovo can help.

I did some testing and research today and this is what i came up with :

1: i tried with Ubunto and the random black screen still there (no windows driver problem).

2: i plugged my tv into my laptop to see if the black still occur, result : no random black screen my laptop work perfectly.

3: i tried the monitor with a satellite receiver, result : no black screen.

i think the problem come from the monitor firmware, it didnt interact properly with nvidea graphics card and cause some random black screen.

The problem seem to be some current instability in my house, others electronics devices that I have work perfectly by the way, I'm going to buy a uninterruptible power supply and test again.
