There goes me using laptop as a monitor.
when i flick scroll this pic quickly left or right, it kinda changes half a second after it stopped
Assuming the device isn’t sealed in epoxy, I’d open it up and reflow the solder with a hot air gun. Hey, you never know, sometimes just giving the chips a hot attitude adjustment can get it back working again, if only for a while. Besides, you really ain’t got anything to lose…
Heh, seems it already attempted that itself
That chip with heatsink gets too hot to touch within a few minutes even on open air, and that was fully enclosed in plastic. It also doesn’t even cover the entire area, though I am not sure how much that matters in this kind of chip.
So I guess it cooked itself.
The fact that it even partly still works is still a small sign of hope. Although it’s already overheating as you say, I’m sure it’s not getting hot enough to outright melt the solder.
Between 2010 to 2015 or so, I was reballing overheating and failing nVidia GPU chips, which basically means to replace all the solder beads on them. And yeah, it would usually work for a couple more years or so if done right, until it eventually failed again.
Scientists ultimately discovered that wasn’t the true root cause of the problem, but it did manage to resolder weak solder points, which kept the chips working for a while longer.
What I noticed was that a number of the ground connections on the chips were gradually coming loose, which put more stress and heat points on the remaining ground points. Resoldering the chip managed to not only restore those weak ground connections, but also apparently helped relax the crystal structure of the chip itself.
TL;DR - I’d try reflowing the solder anyways, just for the hell of it. Nothing to lose ya know. And if by chance it does work, well to hell with that plastic shell, cut a hole in it above that heatsink so it can get some air, maybe even add a fan.
Like what the hell were they thinking, sealing a heatsink in a package that can’t get any airflow? 🤦♂️
People would pay money for ricing like that!
In all seriousness, RIP O7
PS. I’m terrified of my laptop’s display dying cause it’s high refresh and I CANNOT go back to 60hz
