Hi, again!
So, first of all, this is a refurbished laptop I bought back at 2021 (probably a model from 2019 or 2020, if that’s considered old enough)
Now, I have forced the laptop to trigger the issue by repeatedly closing and opening right now and I am writing as the screen flashes at this moment:
Having tried increasing brightness up to 100 %, the issue persists. Additionally, lowering all the way down to 0 % doesn’t solve it either.
Thank you, though; I’ll keep looking for clues.









Hi, and thank you for your detailed reply. You brought up a few interesting points I hadn’t considered.
While I haven’t had time today to look into all your suggestions, I’ve focused on the last two related to the BIOS:
First of all, aparently, my BIOS does not have, or at least I have not found, an option to disable either GPU. Perhaps I’m missing something but, going to the advanced settings, this is all that shows up:
Secondly, I have run the “inxi -Faz” command and it tells me my BIOS version is from January 2021. According to my laptop’s manufacturer website, the latest BIOS driver available for my system dates from March 2021, so I’m not sure it would make a great difference, but I will still look into how it could be updated without using Windows (which I no longer have lol).
As soon as I have the time, I’ll take a look at your other suggested points as well.
Thank you and have a nice evening!
