EUROCOM (Sager) screen flcikering?

[apelin20]

Hey guys,

So I need a bit of interpretation here. I bought this laptop is April 2012 when Ivy came out, so it hasn't been a year yet, still got warranty.

I wake up one morning and see this:

(video rotated if not viewed with quicktime... iphone...)

So this is really scaring, to me it looks like a defect, why is the screen doing that?
So I restart my computer, problem gone, and it's been 24 hours and it didn't come back.

So is this common? Will it come back? Do I need to push for a replacement? And how do I do that? I would love a free screen replacement

Thanks

This is probably a problem with the gpu which will not go away. See if you can get the warranty.

The problem has vanished for now and I did not see it in the last 24 hours.

How do I reproduce it? How do I make it happen again to make a case?

Hm... You can use FurMark or Heaven Benchmark to stress-test your gpu, but if I was correct about the screen "artifacts," then reproducing them would mean causing damage to your gpu.

I tried to stress test it with Heaven Benchmark and then I played SC2 with ULTRA settings for about an hour, it didn't get stressed apparently.... I will try stressing it with passmark benchmarks and see if I can reproduce the effect.

Hmm. FurMark is a free program that is just about the best gpu stress-tester out there, I guess the issue was the screen then....?

 

[apelin20]

I will try FurMark today, but I do not understand how the screen can cause this and then go away...

Okay SO I tried FunMark, and I did a Burn In test for 17 minutes. The temp went all the way to 99 degrees. My avr frame rate was 11, at a resolution of 1080p. Most of the time I had a message saying THROTTLING -310 MHz not sure what that is. So since temp was 97-98-99 for most of the stress test, can we assume it is not the GPU that is the problem?

Now that I remember as to when I took the video, it was after a resume from Hibernation one morning. And restart fixed it. So the restart fixing it makes no sense if the screen is broken. If it is broken it is broken, why did it regain functionality. And if it is the GPU, then why doesnt it crash during a stress test.......

sorry it wont allow me to edit my post, I did another 60 second stress test:

:-0 99 degrees is not good, throttling means that it reduced the speed of the chip to keep the temperatures down. I guess we can assume this is normal as its a laptop and it will never be running anything as stressful as furmark. Either way it "passed" the test.
I am out of ideas.... I guess the computer was having a bad day?
