HP Probook 650 G2: Fan is constantly ramping up and down

[jizw]

Yes, the latest BIOS version was implemented by our IT last week on Friday.

Dear all

I have the same problem with the fan. It runs all the time and ramps up and down.

It is very distrubing at work and in meetings.

I've updated the firmware to 1.02 and installed a fresh Windows 10 pro. No luck.

The starts to run after a few seconds after the systems boos.

The quality of the 2016 HP Notebooks is very poor. I'm also disapointed about the HP 840 G3.

Just received a brand new  Probok 650 G2 with the same issue (Bios Firmware 1.0.2). Really anoying fan sound. Is there any solution at the moment?

Hi

The HP support was not able to help me and did't understand the problem.

I mean this is preatty clear that it is a firmware or a driver issue but not a physical problem with the fan.

The support wanted to change the fan what I did not accept on a 3 day old notebook.

So I requested a "dead on arrival" exchange. But i'll not buy the same notebook. I'll have a look with my hp dealer what he can offer me as an other option from HP.

Hi All,

HP support understands well the reasons, but they try to avoid offer "expensive" solution. The NB has also another bug - the external monitors drop out randomly for max resolution (The previous Dell worked with them without any problem ). Unfortunately my piece is a company comp. So it will be long distance process of claim. Related to fan troubles: I set up the power management to max battery mode and the fan sometime switches off if no application works and display is set up to minimum brightness.  But it is not solution. The only acceptable solution is to set up the temperature threshold for higher value or change fan for first-rate and silent type. But I have no way how to do it. I think the best solution is to return NB if the guarantee allows it. And avoid this HP for future if possible.

Hi,

Try this tool (link), it works like magic. I use it for years. It is still being updated.

I see the HP ProBook 650 G1 is supported, it should be the same.

I use it for years, and now on Windows 10, with my HP EliteBook 8560p.

Without this tool I would have thrown away my laptop long time ago, suffering the same problem. I replaced my cpu fan 3 times, even with different models. The tool is the (only) magic solution.

My next laptop will be fanless, that is why I haven't replaced my old 8560p yet.

I apprecite the help, but this program does not fix the issue. Even setting the fan speed to let's say 40%. the fan will still ramp up and down. At idle, the fan will go from 22-28%, even when you set a fixed speed.  

HP needs to get a Engineer to look into this issue.

Hi Heino081076       ,

tx for solution proposal. I tried it and it solves 90% of troubles. I set up "Enabled" and "Target fan speed'' to cca 1,3 % (to the lowest possible value). This setting pushes the regulation loop to ignore the temporary temperature changes and the fan starts from almost zero to full speed at arround the 70°C on CPU. So the intensive noise is related only to high power consumption and the fan is silent during normal work. I don't understand why HP tries to cool down every small change and disturbes the users with this annoying ramping noice. Tx again, it works.

Hi All,

I also had the same suffering as you guys with this notebook. This is my company notebook i use all day long, and i also hear this sound in my dreams. I have requested a DOA for the first one. Today (after waiting 2 weeks for it to arrive) I finally received the new notebook. Unfortunately this one also has the same problem with the fan ramping up and down!

Please HP fix this issue with some BIOS firmware update or something. This is totally unacceptable!!! We all have this issue and it seems we don't get taken seriously. This type of notebook should be robust in every aspect, as this is our tool to get our jobs done!

I am definitly not going to advise this model to any of our customers!
