Fan surging on Mini 110-3538tu netbook

Hi all

 

Just picked up my new Mini 110-3538 and very happy with it, except for one thing - the fan noise is continually surging from soft to loud.

 

It is brand new out of the box so there should not be a problem with dust, but the noise is driving me crazy... if it stayed at one level it would not be so bad, but it goes something like rrrrRRRRrrrrrrrRRRRRrrrrrrrRRRRRRrrrrrrrrr.

 

It's as if the device heats up enough to speed up the fan, then once the fan speeds up it cools down and the fan slows, then the cycle repeats once every couple of seconds. In my past (engineering) life I would have called it a hysteresis problem...

 

Thanks for any suggestions.

Check the BIOS to see if there is a 'Fan always on while on AC Power' option and disable it.

    Thanks for the response - I would love to give you kudos, sadly not there yet...

     

    I changed the BIOS setting so that 'Fan always on' is Disabled.

     

    Unfortunately the fan still runs fast and slow as before...  Temperature here in Adelaide is 20C so that should not be a problem.

     

    Any further ideas appreciated.

    Oh no!

     

    And it's brand new right?  So a dusty/clogged fan wouldn't apply here.  It's odd that you would have that issue on a Mini as they use a tiny little atom processor, not a super hot i7 or anything like that (Envy Users have a lot of heat issues).  Does the laptop feel hot at all?  If not it could be a faulty fan, if you just bought it I'm sure you can have that looked at/replaced under warranty.

    Hi Miniuser...got exactly the same problem on my wife's brand new mini 110-3538tu, fan goes up and down in speed like a yo-yo.  Thankfully there is a cure...Go to Control Panel -> Power Options - > Change Plan Settings then click on Change Advanced Power Settings. This opens another pop-up window. Scroll down to Processor Power Management & expand, then expand System Cooling policy. Here you will see the options for running on Battery & Plugged in. On mine they were both set to Active. I changed both to Passive. the fan runs a bit faster but at least it is now at a constant speed.

    Adjustment of the power supply fan option in the settings, this computer work is not very good, small is a problem of the heat, it did. Quality! 建议购买lenovo Thinkpad高端产品

    to all users who have this fan problem.   i just contacted hp and told the,m the problem backed up by evidence from this forum and so forth. they picked it up from my office and repaired it by replaceing the fan and now it works like a wonder! So quiet you wouldn't believe it! Actually there service has been A1, i was very impressed. So if your netbook is new and making a noise, it shouldn't be. You've basically got a faulty fan and it needs repairing. 

     

    Good Luck to you all

     

    Happy Days

    I have the same issue. The problem is inherent with the fan. The bearings are made poorly. I've been in IT for a while and I see this a lot, especially with Sony Viao's. Blowing compressed air in the exhaust or intake port full blast is bad. You will further damage the bearings. For dusting you need to do sweeping passes just like spray painting. 

     

    The only try repair for this is to get a replacement. Probably cheap on Ebay or order one from HP if your mini is under warranty. 

     

    Simple fix. On most models you pop off the bottom, and the fan is usually held in by 3 to 4 mini screws. 

     

    Hope this helps.

    Bundles of Thanks. Along with fan surging, my mini got stuck on unplugging. I set both options to Active (previously on battery is set to passive) and it resolved the issue. Thanks alot.
