You will have to contact them Monday - Friday. Others have reported the same sound and if you only have an SSD and not a traditional hard drive, the noise will not come from the SSD as they are totally silent and have no moving parts.
Greetings,My Aurora R15 is making a vibrating noise and it's coming from the PSU area. I contacted Dell Support thinking I had a faulty PSU. First, I was advised that I need to enable Hibernate to stop the clicking noise. Huh? What clicking noise? Support was adamant that I had to complete this step first, before we would address the issue I originally contacted them about. After recording a brief sound (it's hard to get, it's intermittent), Dell Support determined it's either a fan or my SSD, and that 'since it was the weekend, try again on Monday'. [IMAGE]Sigh. This thread has a video with an identical sound. How do I get this fixed?
