Fujitsu Heating Problem

Alright i am trying to undervolt this laptop. It's a Fujitsu Lightbook A3130. IT has an AMD Turion 64 x2 with each core running at 2.0GHz(not overclocked). The problem is when i try and stress test it using Orthos i get to very dangerous temperatures and have to stop after only 16 minutes of stress testing. the highest i let it go was 101c (Celsius). and that was when i was undervolting it by .025v.

It's original voltage at the highest multipler, which is 10x is 1.125, and i was running it at 1.100 and after 33 minutes i had to stop it because it was getting way to hot. What can be the problem for these extrememly high temperatures?

The worst part is, i tried undervolting it to 1.05 which is the next one down below that and it turns off after a few minutes. No BSoD, no errors in Orthos, just powers down like if i was holding down the power button.

i was using RMclock to change the voltage, HWmonitor to tell the core temps, and Orthos to stress test it using small FTT.

1 more thing, only 1 of the CPU's was heating up that high, the other never got passed 88c.

 

I think, the system only shut down when you tried undervolting, cause the thermal threshold of your laptop was met.
Literally, your laptop should not be running more than 80C under full load.
I would let it sit for a few hours and cool down.
Then I would try undervolting again.
I have never had a system flat out turn off cause of undervolting. A BSOD or a freeze will occur.
Your amd turion should be able to undervolt like 0.2 - 0.3 Volts.
Let the system cool down and run again.
Also do not undervolt while running Orthos. Its not a good idea.

You have cleaned out the inside? Dust and all? Also be careful trusting 3rd party apps for accurate temps. I do know it is running hot but you don't know.

 

Well, something else happened now...

It shut off while running RMclock on it's default settings. We did this to test and see if it was a temp problem, or an undervolting problem. but after a little while, even though the voltage was set to default, it shut off. Without running RMclock it runs and doesn't shut off, and playing a game on it still sends those temperatures flying.

Here is a bit more information, I'm running windows Vista Home Premium 32-bit.

Thanks for the replies, any ideas?

 

Are you using Orthos when it shutted off???

I run at a constant 2.25 GHZ at 1.075v, its stable here. Anything below iwill get me BSOD

 

Try using Notebook Hardware Control for undervolting, rather than CPU Rightmark.

no I wasn't, I was just running Rightmark.

 

this thread is givin me a thought....

how long is too long for a laptop to be running...

and

how does heating affect performance

what is undervolting?

 

As long as you need it to be would be my answer in the first question.

Heating will slow down your processor or GPU and will reduce life span.

Undervolting is when you reduce the amount of voltage that your processor gets.for more info go to"The undervolting thread" search NBR
