This has happened 3 times in the past 2 days, any advice? It goes away after reboots but always comes back.
Update: So it could be GPU death, how exciting, especially for a 1.5 year old laptop. As of now it hasn’t terribly affected my workflow, but if this persists even after future kernel/driver updates, it may be rip. I am still hopeful that it could be software related, but time will tell!
This one is a little more interesting
Update 2: I was using Windows for testing purposes, and it happened again! This was immediately after picking the laptop up, so it is definitely hardware related. This time it made a horrible noise as well, answering some of the questions. So somehow by picking the device up, maybe the internals are slightly bent, causing the issues?
GPU.
Update or rollback drivers and see if it stops.
looks like you did a sudo ▓░▒
Never do a sudo psi thundershock
It’s the GPU, almost certainly the solder joints. So how far are you willing to go?
You can pull the MB and bake it in an oven. Fixed a card or two that way, didn’t last very long. Damned fine line between too much and too little heat and time. Bon chance!
In related news, MBs can be pretty cheap on eBay.
I assume the reflowing solder in the oven trick doesn’t reliably work anymore in the era of the high temp solders that are common in laptop manufacturing these days. Bringing the whole board up to flow temp in something as crude as a home oven is almost certainly going to fuck something else on the board.
I recall trying to do a laptop repair with dinky little soldering iron I got at the hardware store and it could not melt a single thing on the board I touched it to. Definitely not a faulty iron because I used it to successfully solder other things. This was at least five years ago. If that little toy couldn’t do it, then the entire board would need to exceed that temp in an oven, which is probably a bad idea since the iron was still managing to visibly scorch things despite not melting any solder.
Invest in a proper heat gun and learn how to use it, or just give up and give it to someone else who has one, imo.
In my experience I think the trick is to underheat it but leave it in the oven a bit longer.
This is, for the most part, a myth and not worth doing. Reflowing is not not repair.
My intuition is that it is a hardware failure. GPUs can develop issues that show up intermittently. You can try running GPU stress-testing software to check if that’s the case.
However, did you recently update your graphics drivers? If you did, try rolling back to an older version.
Does it happen faster the 2nd time around? Probably a heat issue. Make sure the fans are working and the heatsink fins are clear of dust and debris. Try that first, and run a gpu stress test https://mprep.info/gpu/ but it could also be drivers as others have mentioned, or even a faulty or incorrectly seated ram module.
You could boot into a live system and see if the problem shows up there. If so, it’s very likely the hardware.
The pattern looks like a GPU, more specifically a problem with VRAM.
This looks like a low to mid range HP laptop, so I question whether or not it even has dedicated graphics.
Systems with integrated graphics share RAM to use for graphics functions.
To test VRAM, one would use Nvidia MATS/MODS or AMD TServer/Memtune. They are not very accessible for the average user.
To test RAM, use Memtest86. This one is free and relatively straightforward.
It could easily be the GPU drivers or the display cable.
There any many other possibilities, but hopefully it’s one of those two because the fix is is either cheap or free.
Its an HP, never buy HP!
This. Especially since they still have the worst hinge designs on notebooks I’ve ever seen and they have continued to build them so shoddily for years. It must be deliberate at this point.
It is cause it makes them money. I wanted to change the battery on a family members hp laptop. I opened it and everything is glued/solder together. Told her to get a dell!
Very fucking helpful
any chance it’s overheating? did you clean the vents and checked the fans?
Looks like A Dying GPU.
Could be either hardware or software.
I’d try updating the bios and video drivers first, failing that it could be a failing video card. It could be the screen too.
To test if it’s the screen or the video card, connect it to an external display and see what happens.
My Debian dies this everytime i Start, but it goes away after a few secs, doesn’t do that on windows, so software bug is not impossible
