Hi, I'm the colleague he spoke about. I have a different laptop from you
(Eluktronics THINN 15 with Ryzen 7 4800H), but this sounds just like what I
experienced. For a long time my laptop was fine, but then one day temperatures
around 80C started causing my display to go black or flicker rapidly. As the
laptop cooled down, the flickering slowed and the flickering would appear as
noise on the screen just like in your pictures until it finally went back to
normal. 80C isn't particularly cool, nor is it what I'd consider overheating.
It's normal when the CPU and/or GPU is working hard, but it must have been too
much for the cable near the heat pipe after using my laptop for CPU intensive
work for 2 years (you also said you had your laptop for 2 years). This doesn't
mean that 80C is your laptop's threshold for triggering the issue, I'm just
saying your issue sounds similar to my issue. Ultimately, sending my laptop to
the manufacturer to get it repaired completely fixed the issue.
