v4000/dv4000 question

[taylor138]

I got my v4000t a few days and as far as I know there have been no problems with it.

But i've been wondering if the fan is supposed to go on and off every 15 to 30 seconds or so. I only seem to notice this occasionally, as I am right now browsing the internet. It's just a little annoying, but maybe it's just because i'm afraid it isn't normal operating behavior. Playing games, the fan is usually always on.

Thanks.

Mine should be inby next week sometime. I'll let you know how mine behaves.

Ohh! Behave!!!

BTW, which processor do you have?

[taylor138]

I have Pentium M 750 (1.8ghz). I really love this computer, i'm just paranoid about little things. Me and my ocd...I'll check back and see whenever you get yours. Thanks

I forgot to mention that eventually the fan decides to stay on permanantely, although operating at a low and quiet rpm. When gaming it will speed up and slow down back down eventually, but it does not turn off. Is this normal?

[WonderDude]

I don't know. I do know that your processor has a slightly faster frontside bus than mine and will for this reason probably run a tad hotter. But I really don't know yet.

I would install Notebook Hardware Control and set it up to use "Dynamic Switching" for CPU speed. In most cases, you are never going to need the full 1.8Ghz when using a laptop, so even if you are on AC, 800Mhz is fine for regular tasks. With dynamic switching, if you start to do something CPU intensive, it'll jump to whatever speed it thinks will do the job quickly enough (it won't always go to 1.8Ghz, which is nice when on battery).

Also, you might want to try undervolting. That will decrease the voltage going to the CPU, which should decrease temps some and improve battery life. If you want to do that, I think there is a tutorial at www.notebookforums.com and it should show you how to do it. Make sure to undervolt in steps!

There's plenty of information about undervolting here. Usually, people undervolt Turions but as far as I know Pentium Ms are good undervolters too.
Don't let undervolting scare you - it is very easy and harmless; actually it should prolong the life of the notebook because it decreases heat output.

I got my V4000 ..it only have Pentium M 725A, 256MB memory. Got it cheap at ebay for only $600. I do add a 1gig of memory so i can work with multiple apps.. I have a notebook cooler so i really dont notice if the fans of laptop is running or not.

I recommend using MobileMeter - it helps you monitor your notebook's CPU Core temp, as well as it's clockspeed and HD Temp. as well. This way, you can be aware if your notebook is getting too hot/going to overheat or not.

Thanks everyone.

I've tried all of that and everything seems fine. Temps are usually under 55 for CPU and under 60 for GPU. HDD is under 40 on average. I've noticed that when plugged in to ac power (running full time at 1.8 ghz) the fan usually is on permanantely. When running off the battery it cycles off and on but usually stays off.

The fan only gets really noticable and loud when playing games.
