Working since a half year or so with 840 G5 I7 8th Gen.
Cannot confirm no coil whine, neither am I happy with the selection of ports.
If working on Desk unit is usually docked, so why RJ45 Network native? One more USB A would have been the better choice. Only 2 Standard USB A ports allow pluging of company supplied Mouse and headset. To plug in all development and other USB stuff I need a Port Expander or dock in HomeOffice (using Icy Box Dk4050 here with no probs)
USB C Connector is very close to standard Power Supply Conenctor, that could have been exchanged against another USB C Port with PD feature and a PD PSU.
Fan comes on frequently. Not extremly noise but with hearable alternating revs, which is very inconvinent, loud under load (Companys Antimalware
scan takes half an hour and drives Unit to maxload fan revs once a week and I then usually take a looong coffee break :))
Build quality ist very strong and sturdy, keyboard it self is nice, if you can l livve with the strange layout.
Compared to my personal X390 Yoga I prefer that keyboard and its layout if this helps any.
Touchpad is very good.
Display is lower end IPS type. Matte is very nice, viewing angles good, but the Display from factory has a very greenish tint, which may be problem of the display itself as I can reproduce it with 1pix white/black alternating vertical lines in native resolution. INstead of showing a homogeneus grey the Unit shows a light greenish grey. I wouldn't have expected this with a relatively large colour Gamut given.
All in all an acceptable unit and comparably lightweight with its 1500gr. it feels heavier subjectively, probably due to size and Alu-Chassis.
SIM Slot is completly useless and a waste of connector space. SD-Card reader instead is painfully missing.
