Fujitsu S6311 heat/fan problem ?

hello,

About 1 month ago, I bought a Fujitsu S6311. Everything worked fine until last week when I noticed that the fan started to work abnormally often (it starts every 2 minutes or so when on AC, a bit less when on battery). The point is it didn't do so for one month (couldn't even hear the fan, or maybe just once or twice).

I didn't install any new programs which weren't there before, and I checked for any running processes which could use CPU, monitored the system activity etc., but couldn't find anything. The point is the fan starts to work even when there is not even 1% CPU activity. Will try though to monitor the processes with a better tool tonight.

What worries me is that nothing has changed in the configuration (eg. room temperature, notebook location, any new installed programs etc.) I only docked the S6311 onced to the docking station, but this shouldn't have affected it.

I even reinstalled the system using the recovery CD yesterday. Today I made all the Windows Updates and the Navi Updates, but nothing has changed.

Could anyone help me ? Thanks a lot,

Larry

 

Send it in for repair. I had same problem with my 6231 and it got progressively worse because it wore the fan out. Its a defective fan. Dont bother trying to fix it yourself - you cant.

 

Hi,

Thanks for your help - yeah that's what I'll do - besides, I just noticed something else yesterday evening. When wireless is off, I hear an intermitted high-pitch sound coming from where the wireless card sits (left handside of notebook), and as soon as I turn the wireless card on, it's gone. It's not much, but I can hear it, and it drives me mad.

I was really pleased when I bought the notebook, it exactly fitted my needs (13.3), small, handy, but come on, my Acer of 1999 makes less noise (and had never to go to repair, by the way)

Long live to international warranty ;-)

 

Hi LarryK,
I also experience the high pitch sound frm the left side of the laptop. i am just wondering what happen to your laptop now? did you manage to find out what is wrong with it? i tend to hear it when wireless is on and when off, the sound gone.
Also, i am just wondering how is your wireless signal strength on you S6311. Did you get full signal?
i would really appreciate your input. thank you

 

not sure if understand correctly but try this. right click my computer and select manage, now choose device manager and scroll down to universal bus controllers. now expand this menu and choose usb root hub right click it and go to properties. now select power management and click the option the "allow the computer to turn of this device to save power" this will not disable your usb ports. but may kill the high pictch sound.

 

i'm pretty sure what you are experiencing is the cpu whine. i searching that on the forums to find the solution (the one mentioned above is one).

also, are you using vista? i think vista may have different standards for reporting wireless signal. as long as you are getting good speeds, you should be fine. in the past, i had two notebooks, one reporting full signal on xp, and another that only had 2 bars on vista. they both had exactly the same download rates.
