I hope this is the right community for asking this question.
I got an HP ProBook 470 G5 (i7-8550U) and it makes a strange noise/ whine (here are three sound samples).
Since it has no HDD, I think it comes from somewhere on the motherboard and it may have to do with the state of the processor (i.e., in load 40% or higher the sound decreases in intensity).
Two possible solutions:
- if I disable
Turbo Boost
inBios
, the sound drops considerably - if I change the settings in
Power Options
->Advanced Power Settings
->Processor Power Management
->Minimum / Maximum processor state
to less than 100% the noise decreases in intensity
However, for both solutions, the score in CPU Mark drops from ~ 8200 to ~ 5500. So, there is performance loss.
Other mentions:
- I've tried the latest drivers, both from HP, and those from Intel this is the second ProBook 470 G5 that has the same problem (i.e., it's actually replacement to the first which I returned for the same reasons mentioned here)
- about two weeks ago I had the same problem with an Envy 17-ae120nd with the same type of processor
- my issue seems to be related to this post on the HP forums
- this is the manual of the product in question
My questions are:
- what is causing this noise?
- is this a sign indicating that my laptop is defective?
Thank you for your help.
