If it's a skylake CPU, chances are it has nothing todo with USB3. There are some coilwhine issues in the power delivery system when the GPU is entering and exiting power saving modes and is heavily plaguing the recent Dell XPS 13 model amongst others.
- voltagex_ 10y agoI'm guessing it's not really worth RMA'ing my 9350 for that coil whine issue. The problem where the Dell WiFi driver causes screen flickering might be, though.
- Zagitta 10y agoI talked to a very nice service rep about the coilwhine and he said there wasn't much point because all of them suffer from it in varying degrees and they would only do something about it if it was very audible and then only if RMA'ed within the first 2 months or so. His suggestion was to disable the GPU power states but that sort of defeats the whole point of an ultrabook. It's a sad issue because it really detracts from an otherwise excellent laptop. I have not heard about that specific wifi issue though, have you updated to the latest firmware? I know there's been quite a lot of versions with various fixes.
- blinkingled 10y agoNope, it's a Haswell NUC. Skylake is problematic though, yes. Got a desktop Skylake Dell Precision and it was weird to see all that unreliable behavior - USB bootable disk sometimes would work and sometimes not. The computer itself would sometimes fail to start back up after it had crashed trying to suspend etc. It was fast with NVMe boot disk and 64GB RAM but it's a bag of pokes!
