Amilo M1451G insane temperatures

Postby vangelisk1983 » Sun Aug 13, 2006 12:41 am

Hello people! I have an Amilo M1451G wich has the Pentium M760 on board (2GHz) and my problem is the temperatures the laptop has: on full work load the processor reaches 95 degrees celcius and the hard disc 58. It cannot be normal, eh? What should those values look like? 75 or what? I had the laptop cleaned by fujitsu siemens here in Greece a week ago (before that it would turn off after exceeding 100 degrees celcius easily...) and now, with absolutely no dust inside, it reaches those insane temperatures. What can I do? Should/Can I demand that they replace my laptop? Is there any way they can fix it? Please somebody show me the light!!

Thanx a lot in advance!


P.S.: I checked the temperatures with programs like everest and notebook hardware control.

If these temperatures are really correct (and I think we can assume that because your laptop powered down due to heat), then something is wrong.
Does the fan work?

Yes it works like a charm. The FSC people told me there is nothing wrong woth the laptop after the cleaning, it works with their benchmarks just fine. But I am thinking it is no good that it reaches 94 degrees celcius in an air conditioned room... They probably had it in an a/c'd room as well. I think they just did not pay attention to the temps since it did not power off.

I think it is more than this notebook should have. But if you dont have any problems any more so that you can do everything without the notebook shutting down, don't care about the temperature. The CPU resists about 100°C.

But maybe you should try to bring it back for repairing.

How did you understand that it reached a 100 degrees? Isn't it the temperature in F not in °C. It would be impossible to work with(to touch) it if the temperature is really that. The CPU fan should work non-stop, is it so? Or may be just the temperature sensor is freaking in some way.

in the Pentium M Data Sheet on intel.com you can find that the CPU switches off at about 100°C which is about 212 degrees Fahrenheit

It's definitly not normal. My CPU (I have a M3438G, wich is also know for being an hot (Literally) laptop), and from factory, the CPU never passed the 60º Celsius, on a room at 28ºC. After I undervolted it, even after intensive gaming or video enconding, it never goes past 50ºC.

I would advise you to undervolt your CPU, but the best thing to do, if possible, is to demand the substitution of your system. Operating at those temps will greatly decrease your system's lifetime.

Cheers!

hello ppl. i contacted the fujitsu siemens service again today and they told me if the laptop does not shut down then there is no problem. i said is it normal that the temperatures are almost 20degrees celsius higher than other laptops of the same kind and he said well if it does not have any other problems i cannot do anything, everyting is normal. i am contacting siemens in germany tomorrow hoping for some more.
i get 93-94 degrees celcius, not farenheit. yes, it is aufully hot. i know that my laptop is dying and i cannot do anything about it. great stuff.

But it seems curious that the notebook doesn't shut down! Try to check these temperatures with a thermal probe, usually on some multimeters. The corpus shouldn't be higher tha 70 degrees, I think.

I think most systems shutdown when the CPU temperature reaches 100ºC or more, unless that setting is changed (don't know how, maybe some BIOS allow that).

Actually, it's a funny thing, today I was at a neighbour's house, an old man, who many times asks me for advice or troubleshooting when he has problems. Today I teached him how to open the computer's case, disassemble the components, and clean the dust off. I removed the cpu to show him how it was, and so on. I noticed the termal paste was kind of solid (and this sytem is only one year old), but I assembled everything again and took no notice. When I restarted the computer, it just kept constantly booting, it wouldn't even be one minute on. Eventually I checked system temps at the bios menu and the CPU was at 80ºC up! :shock: I imediatly went home and brought thermal paste, cleaned the old one off the cooler and the CPU, reassembled everything very tightly, and shabang, system on again, CPU temp went down to 50ºC.

All this story to tell you this: your CPU might not making contact with the dissipator. That will make the heat stay in the CPU, making it reach insane temperatures. Another possibility woulld be old and solid thermal paste that won't transport heat from the CPU to the dissipator effectivly.

From what I understood, your laptop is still under warranty right? Because if it isn't, you might want to open it and check your CPU. Buy some thermal paste (really cheap, like 2€ -3€ (2.5$ - 3.5$) and replace the old one.

Anyway, terrible answer you got from them. Do whatever you can to solve that problem. One thing is for sure: you can't leave your computer to work in those temperatures. Either make them replace or have it repaired. :?

Good luck!
