HDX16T: Fan always on?

Have anyone notice this: The HDX16t will run the fan if the power plug is plugged in and will do so until you hit 100% on your battery meter.

I went into the BIOS to disable "Enable Fan Always On." And yes, when ever my notebook is not connected to power, the fan is OFF. But as soon as I plug in the power chord, back it turns on. While charging, as soon as I pull the chord (even though the battery hasn't met 100%), the fan turns off.

Who heres know how to fix this?


And another question, my HDX16t has this high pitch noise that you can hear. It's sort of like that same issue back with the hold dv6000t models.
How do I disable that, or remove that noise. And no, its not coming from my SSD or my Cd drive.

 

I don't know that particular computer, but since charging produces quite a lot of heat, you may not want to turn off the fan. To me it sounds like this was their solution to get rid of the heat instead of passive dissipation [spl?].

With that said, though, I'll be just as annoyed about that as you were. It should be temperature based and not just a switch .

 

I have the HDX and mine does the same fan thing. At first I thought it was strange cuz my Toshiba's fan doesn't come on when plugged in. Then I just forgot about it. Yeah i would suggest you leave it on too.

I don't have that high pitched noise you've mentioned tho. But I get a tick tick tick sound coming from inside. It ticks every second. I was like, dude is there a clock inside? Then I figured it must be the CPU.

 

I am also facing same problem. I am using HP dv4 1242 tx laptop. When i connected my laptop on AC the fan spins at full speed creating vaccum cleaner type noise. However on battery it functions normally. Has HP increased rpm of fan to overcounter heat during charging?? Are all new laptops of hp having same noise problem or not??

 

i cant find a way to disable it. its stupid what HP did this. now i just have to recharge b4 i go to sleep. so i dont hear it !

 

This problem should not affect all new HP notebooks.
I have a HP HDX18 that doesn't increse rpm fan when charging, but maybe this is why it doesn't get that hot given the dimensions of this notebook (18,4" monster for those that are not familiar with the HDX18t).

Keep in mind that all batteries get more hot when charhing.It is normal.

 

Marengo thanks for reply.
But what is the solution for annoying fan noise?
I have latest bios available on site (F.24).
I want to know whether other dv 4 users facing this noise problem or I am the one facing this problem??

 

All HP notebooks do the same thing. It's a "feature".

 

chrixx what feature r u talking about??

 

"Fans always on when charging". He means that it was intended by HP, no matter how ridiculous that is (I mean HP are being ridiculous).

 

Normally fan activity is controlled by a sensor.When temperature goes higher than a certain level the fan revs up.
Usually there are various fan speeds that are relevant to certain temperature levels.
Most important is that it is up to the manufacturer to specify the exact temperatures that have to be reached before the fan changes its speed.This is controlled by BIOS.

I remember that my old HP dv6000t was very silent when I bought it, with original BIOS.But when I upgraded the BIOS it became much more sensible to temperature raise and therefore the fan kicked up more frequently and at lower temperatures.This is because HP was aware of the Nvidia overheating problems with Geforce 8000 series cards so the only solution that they could find at the moment was keep the system as cool as possible.This was done by increasing fan speed.

So BIOS version does matter when it comes to fan speed.You have to find which BIOS version has less aggressive fan settings.
Another solution is to buy a notebook cooler and hope that the fan won't kick as frequently.

 

This is stupid. It is not a feature. Its ridiculous that my hdx16't fan comes on and stay on until i pull the plug.

 

My hdx16's fan come on when plugged in but I'm pretty sure it turns off eventually. IMO its not that loud anyway, no where near vacuum cleaner level as someone said. It doesn't really bother me. You must be a light sleeper.

 

Actually, I feel for the guy. I hate constant noise. I don't mind, say, kids screaming, but a steady noise gets to me. Personally, I will get rid of the X200s (which should be here tomorrow! Yeah!) if it turns out it's loud. If it is, however, I wouldn't know where to go from there.
I really, really, don't want something where the fans are loud. I don't even have any beebs and audio messages on the computer I'm typing on, because audio and especially constant audio is noise to me. Same thing with background music.

 

Maybe when it's plugged in, cpu is set to run at 100%. Try changing the power themes...

 

Are you running Windows 7? There's a new setting under Power Options, under Processor power management, called System cooling policy; on battery is set to "Passive" (slow the processor before increasing fan speed), and Plugged in is set to "Active" (Increase the fan speed before slowing the processor).

I also have an HDX16T and changing the "plugged in" setting to "passive" eliminates the symptom you described.

I would recommend creating a separate Power Plan for the specific situations in which you would prioritize quiet over CPU performance.
