Great to hear and know you're getting a great service. I've got the recoil and its amazing. Shame this one didn't work out. I haven't had a restart in a week but also haven't hardly used it so I'm still not 100% sure its gone :(
Yes, I don't run mains power much as it drops the life of the battery, i never enable hibernate or sleep - as you said, so many problems are caused by this.
Definitely smells like a cpu/gpu management power/cooling issue.
After a fresh install of Windows 10 with all updates hasn't fixed it...
@returnofthem hi I'm having the exact same issue as you!
except in my case I ordered without windows - it still came with windows installed in test mode, I just added my license.
I've emailed pcs, waiting to hear back
I had the same problem...
I'm dual booting mint 19.2 and win10
I tried updating kernels from 4.15 through 5.2, to 5.4 -made no difference.
However resetting to bios defaults seems to fix it and the wifi adapter comes back to life on next boot.
If it helps, my spec:
Tongfang GK5CP6Z
v N.1.03...
