Sure this is a design flaw though ... many Dell notebooks have this problem ... Inspiron / Vostro.
This is no standalone problem for the Vostro 5490 ... I know, because we have a lot of different Dell notebooks ...
So they installed a new motherboard and they did not update the BIOS? Amateurish, no?
I would require some more information from you. Please follow the below steps and private message us the below details so that we can forward this further and advise you accordingly further.
1. Please download the collect_log.cmd file from https://1drv.ms/u/s!AnquJC78YNAZiiJ-5qa2uab1AU4G?e=NH619s
2. Run the collect_log.cmd file and specify a file name as logs.txt and press enter so that all the necessary system logs can be collected.
3. Once all the logs are collected by the cmd file and saved on desktop for you. Please send it to us via private message.
4. Please collect HWInfo sensor logs specifically when the noise is heard. The steps on how to collect the logs can be found online at https://dell.to/368oRrq.
I agree @gleva86, if that may be the source for the problem then they should add this important step to the service request.
The fun part is having to go through all the previous steps again even though nothing that was suggested made any difference before.
I'm still waiting on their feedback after I sent some extra information they requested.
Hi RafaelD, our product group team has confirmed there will be some electrical noise from the system & the noise level is within the spec. Kindly try to delete the IDPTF driver from Device manager (delete driver) & update from the Support site followed by a BIOS update again. Check if that helps.^PC
