I have a very similar problem (also with an SF315-52G), I can't wake up Windows with my touchpad after sleep mode. As far as I know these errors are known by Acer, and the whole series have them, so I guess they'll have a fix sooner or later. For now I turned sleep mode off as a temporary solution.

Hello! I have a problem with a laptop exit from sleep mode. When I open the lid of the laptop, it does not respond to its activation and pressing the buttons (even power button). Though there is a heating and operation of the fan is heard. Only after pressing the power button for 10 seconds, it is restarting. Is it a defect or somehow I can fix this problem? Thanks!

Model SF315-52G (NX.GZAEL.002 RU/V2G)

Anyone seen a reference to where this model is available with 4K / UHD display?

User: Abstracted writed notebook have 2 ram slot but this NO TRUE. Notebook have 8GB ram 2133MHz in dual chanal solderling in mother board
User Abstracted is suck and bastardo

Another few points:
* The weight is actually closer to 2kg/4.6 lbs.

* The usb-c port does not support Display port ALT mode so no way to get a 3rd screen output via the usb-c-to-hdmi/VGA dongles. (Confirmed by Acer support and by buying 2 unusable dongles)

I bought this laptop and wanted to add a few pieces of info:
* The m.2 22x80 slot supports NVMe PCI-Express 3.0 x4 drives (such as the Samsung 960 EVO I installed)

* Chassis can be opened with a T6 screwdriver and something flat to undo the clips on the perimeter (I used a small flathead bit)

* Here is a pic of the chassis opened: i.imgur.com/ijWsfBB.jpg
(sorry can't post clickable links)

* The hard drive is under the bottom-left shield, the m.2 slot is under the top-right shield.

* I did not find ram slots, but then again, I was not able to remove the top-center shield (heatpipes are running through it, so I am assuming CPU and GPU are located there). So I would assume, for now, that ram is NOT upgradable.

* Fingerprint sensor is not of the same quality compared to what an iphone or Nexus 5X offers. I most often need two or three tries until my finger is recognized. Many fingerpress are simply not recognized (i.e. no response at all from laptop).

Acer says that the Acer Swift 3 SF314 14" has soldered in RAM, but this Acer, the Swift 3 SF315, does not. There are 2 RAM slots, with both memory sticks being user replaceable.

Please confirm that this is true.

Nice review. I'm interested on this laptop, but I have a question. How could you say it has two soldered memory banks of 4Gb each if you did not open the chassis?
