DV1000 owners: What is your CPU temperatures and How is your Fan Noise?

I bought a DV1130 which comes with a Celeron M 360 (1.4 GHz / Dothan) and I am wondering if I got a lemon

Because the cpu temperature at idle ranges from 61-64C, which seems very hot to me. My i8600 with a Pentium M 1.6 GHz (Banias) has a temperature of 42C as I type this posting.

With the temperature in the 61-64C range, the fan cycles on on for like 15 secs and then off for 5 secs continuously. And the fan is pretty noisy when I turn it on in the library. When the fan on my i8600 turns on I barely hear it. Even my Toshiba A15 with a Celeron 2Ghz has a quieter fan than the DV1000

I tried using SpeedswitchXP and CPUCool to try to control the DV1000, but they don't seem to work with Celeron M

My battery reading with wifi off and screen turned to middle setting of only 2:05 The reviews by magazines and people are stating up to 4 hours with the 6 cell and Pentium M. I figure that a Celeron M should get 2.5 to 3 hours. For supposedly a "multimedia" notebook, I cannot watch a DVD

What do you think? Thanks

Yes, I've heard of heat problems with dv1000, so I don't think you are alone.

I think it may be the Celeron Processor, which has Thermal Design Power (TDP) of 21 W (speedstep is disabled in Celeron Ms). In comparison, Pentium M (Dothan /w 533 MHz FSB) has TDP of 10.5 W in LFM (lowest frequency mode; 800 MHz). So if the processor needs only 800 MHz to run DVDs, Pentium Ms dissipate half the heat of what the Celeron M processor does. Also, you said that you had i8600. Banias had TDP of 7.5 W in LFM, which means that Dell's processor dissipates 2.8 times less heat than the processor of dv1000, which would explain the difference.

The Pentium M based dv1000 used to run around 41-45C on regular usage. But on full power (100% cpu utilization) it ran aroung 60C.

Since the Celeron M has none of the deep sleep, speedstep and the other nice stuff the P-M has it will run at max speed producing all the heat it wants.

Battery life is probably what one would expect of a Celeron. Remember that the reviews are based on maximum battery life not the average, so your battery life will always be a little lower. With mine, the 6cell used to give around 3.5hrs wifi on.

How do you check the temperature?

I wish I knew about the heat problems before buying it

I wonder how did Intel disable Speedstep? Is there a way to mod it to get it back? How about software to modify settings?

I thought that the newest Pentium Ms and Celeron Ms would run cooler being fabricated smaller. I checked out 2 DV1000 with PM in them at Compusa and their temps were 61degrees C, but the display platform kind of block the DV1000 fan intake and they were on all day, but the cpu was not doing any work. It appears to me that HP could have done a better job of engineering this notebook. Compare to my Dell and Toshiba the cpu temps are higher and the fan noiser. It seems to me that HP has noiser fans because in the library yesterday I walked past this desk and this person's computer have a very loud fan, even louder than the DV1000 and it was another, older HP model, a ZE? 5000/4000f?

I have to check to see what the temps of the Dothan PM/CM are like in other companies' notebooks. If they are lower than HP, then HP needs better engineering. Or just slow the rpm of the fan a little. I wonder what the temps of a Dell 700 or an Averatec 3200/3300(?) are?

It seems that Pentium M are the way to go for battery life or AMD which does lock their chips. Most people seem to want more power, I want a quiet computer with good battery life. I wonder what an Pentium ULV chip would do in these DV1000...

How could I get a copy of that? I'll post up the results of my dv1207us just for comparison.

NisAznMonk,

You can download MobileMeter here or here in English

Errata: Second link is just English translation. Use 1st link to download. Download link is at the top of page. (In English.)

Sorry, I did not realized that English translation page did not have download link. Use the 1st link. It shows download link in English at the top of the page.

Average CPU temperature is 80 degrees C with a range of 60 to 94 degrees C. Currently hovering at 85 degrees C.

Fan noise sounds like the blades are hitting something with a 5 second run time.

80C is very hot. to me 60C is because I have a toshiba a15 with a 2 ghz celeron mobile and it ave 56C

you should return your dv
