RE: Dell XPS 15 L502x buzzing and stuttering problems persist even after uninstalling Dell SupportAssist
Having the same issue here. I have an xps 15 laptop, I tried to run LatencyMon to assess the audio and other processes of the laptop, which in turn, the report said that one or more processes are running longer than expected and advised me to update the bios. I downloaded the bios update from the Dell support page, and ran it. Now my laptop is frozen, fan running at full speed, lost control over keyboard, mouse, touch screen and the power button -.-
Current progress says 90%..and it hasn't changed in 7 hours. I think I will disconnect power and let the battery do its business till it drains and try to start the pc afresh.. Any ideas guys? I'm scared now.
