@hajime: I’m afraid I don’t have any direct experience with Gigabyte service. They operate on a much smaller scale than other manufacturers and from what I’ve read it can take a few days to get a response from them. As was the case incidentally when I emailed Lenovo with the problem relating to my X1E. Being in the UK, from what I’ve seen Lenovo service is not particularly well-regarded here but I suspect it is better across the pond and probably in Canada. Lenovo does also offer the option (I believe) for you to purchase on-site service for machines which don’t come with that already. Gigabyte do not offer that option nor an extended warranty beyond two years as far as I am aware (I’m open to correction on that one).
UK gigabyte customers don’t have to send their laptops overseas since Gigabyte uses a fairly well-regarded repair establishment in England. Perhaps Gigabyte have local service centres overseas as well. That may cut down a little on the time it is away. I hope I don’t have to put it to the test. I got my Aero from Amazon so in the first year I also have the option to send it back if I’m unhappy, without too many complications.
I’m afraid I can’t comment on any Mac related functions.
It seems odd that the fan on your C930 has recently become active. It sounds like you’ve done this already and have checked to see if there is any errant process or service running in the background. You could also start in safe mode and disable all services apart from essential Microsoft ones. If that solves the fan problem you can gradually add back your necessary services until you identify one which has caused the issue. I have had that problem in the past when I’ve had excessive CPU usage on my Dell. However not being able to undo the screw on the SSD is unfortunate. I would be gently persistent on that one, just in case it does eventually free itself. A different screwdriver of the same size but with a better ‘point’ can sometimes do the trick.
If you do decide to get rid of your C930 there are other similar options and I think Dell has just brought out a new two in one which looks nice but is far from cheap.
To labour an already exhausted point ..... as I and others have demonstrated it is absolutely possible to enjoy silence on a powerful laptop for general productivity such as web browsing, emails, Office applications and such like. But if you expect silence when starting to load the machine and undertaking graphical work then you simply will not get that - even on the models which offer the ‘U’ class processors. My Lenovo L390Y is super quiet (in my opinion) but when I’m working in Lightroom and similar the fan does come on (as it should) but it is pretty quiet and to my ears it is very acceptable. My Aero is identical, other than the higher pitch to the fans. I did have a brief period when the fan noise escalated on my L390Y and that was thanks to a BIOS upgrade - a subsequent new BIOS released a month later sorted that out as did a routine reset after installing the new firmware. But as we have all kept saying if you cannot stand ANY kind of fan noise, even if it’s fairly quiet, then you are absolutely on a road to nowhere.
When thermals are described as ‘good’ in reviews that does not necessarily mean the machine is quiet. It simply means the machine’s cooling system is effective - and that can involve any amount of fan activity.
