The screen of my Lenovo Yoga Slim 7 13ACN5 goes black after it's being locked for a while, is it a hardware issue or a issue related to something else?

[u/Stuwaat]

The screen of my Lenovo Yoga Slim 7 13ACN5 goes black after it's being locked for a while. I bought the laptop in 2021 and the issue appeared in 2022 so I've been dealing with this issue 3 of the 4 years I own this laptop (At the time I wrote this post)

I did try basically everything imaginable so it would be a long list if I would have to mention everything I did one by one to solve the black screen issue. For example I did multiple clean installs of Windows 11 sinds the black screen issue on my laptop appeared but sadly without success.

I've then done some more research since I suspected that the black screen issue is a hardware issue. After that I had a discussion with ChatGPT about this issue and he mentioned that it could be a hardware issue.

I want to buy a new laptop with a larger screen after around 6 months from now because I want a laptop with a larger screen but since I'll be using my laptop until then and I want full clarity about the black screen issue I want to ask if the black screen issue is indeed a hardware issue or a issue related to something else.

Thanks in advance for your insight and help lastly!
