I have a Fujitsu Amilo Pi 3560 laptop. Its hardware are the following:
- Intel Pentium T4300
- NVidia GeForce GT 240M
- 3 GB of DDR2 RAM
Since the last summer, I am experiencing a very weird symptom on the machine, and it happens randomly. It was rarely happening a few months ago, but now I experience it once or twice every day. I would be very glad if someone could help me with it.
The symptoms are the following:
- The system hangs and becomes non-responsive
- The last second of sound/music played will repeat infinitely
- The only thing that it will react to is long-press on the power button
- These syptoms occour together randomly at any time, regardless of what applications or operating system are running
- The crashes also happen when there is no sound, so I doubt it is related
So far, I've tried the following:
- Reinstalled the operating system, drivers, etc. Since then I also switched from Windows to Linux, and the problem persists. So I concluded that this is not a software issue.
- Replaced RAM. Some guys recommended that this may be a RAM issue, but the machine continues to experience these freezes even with the new RAM
- Tried various graphics card benchmark applications, some of them even heated the GPU above 60°C, but it didn't reproduce the problem
- I took the machine to warranty repair, but the service was unable to reproduce the issue at all, thus they didn't fix it either
- I also think it is not related to overheating, because the laptop was also hanging in the middle of the winter (even in barely heated places)
I hope that someone can come up with a solution that fixes this, because it is really starting to annoy me.
Thank you in advance!
Answering some questions that the answerers raised:
- Yes, my battery is working. It lasts for 1-2 hours. I can't recall whether the freezes happen on battery or only on AC power.
- The fan is working. GPU and CPU temperatures are usually around 40-50°C, and may go upper under heavy load. The machine can also crash when not under heavy load.
- The files
- I wasn't yet able to find a way to reliably reproduce the problem.
- You can find the output of
- I ran
burnMMXprogram (in 2 instances so that they can burn both CPU cores) for hours, but apart from heating the CPU up to 72°C, nothing really happened.
This was so long ago that I forgot to update with the final result. It turned out to be a hardware bug and was fixed by a warranty repair. Thanks to everyone for their input! :)
