The two PIN beside the Reset is used as system reset, and it is not recommended to weld anything else unless you know the hardware very well
Hi simon,
first i mean the pins beside power-switch (which have been solded together by 2 persons here successfully)
the second one are the pins for reset or the 3 solder-points from the switch itself (i measured 2 go to gnd like in shematics, the other one is bridged to the others if switch pressed)…my idea is to make a simple circuit with transistor (1 of the gnd-points to Emitter, the other to Collector, base over resistor to an arduino-pin) to do a remote-reset

Yes，you can do that.
It is recommended to weld on the PIN of the Reset switch

thanks for the Picture, how about the solder-bridge of power (for poweron without button-press)
Can you please publish a rework instruction to remove the power switch, that will allow the system to boot on inserting the power cord, and only power off with the power cable is removed? If this could maintain a reset option that would be ideal. Right now having to hold down the power switch and monitor the LED is not a good user experience.
For anybody interested I share my idea on how to power R2 including the attached HDDs. As I need to run R2 with two HDDs (one of 2.5" and second of 3.5" size) I had to sort out the problem of how to power it all optimally. After some googling I found power brick that provides both 12V and 5V outputs via standard molex connector. And that did the trick for me.
As you can see from the picture below I power the 2.5" disk from R2 but the 3.5" one directly from power adaptor via molex as I’m not sure if R2 can provide enough current to spin it up (didn’t try it though). I also brought 5V from adaptor to microUSB port on R2 to make it boot automatically after power lost.
Here is the detail of the power brick. It is rated 2A for both 5V and 12V output lines. Unfortunately not clear if meant simultaneously, ie. 4A in total or not. But it works well in my setup. I have attached a dual DVB-T USB donge to R2 too.

Thanks. It’s a lot easier to bridge PIN1 and PIN2 than solder the tiny pads. Take a piece of wire (I clipped off a pin from some spare header pins) and lay it from PIN1 to PIN2. Then just solder each end down. You may want to tape the wire in place or something while you’re soldering.
Here’s a photo of my horrible soldering:

thank you bburky, i’m waiting for official response, that is the right way and nothing will be damaged (if you solder properly of course)
Thank you, that have worked for me.
Hello, I cloudn’t understand what you mean exactly. For what did you use this solution? I need to use 3.5 HDD. Thanks
@bburky’s solution is to poweron on power available (without pressing the power-button 10 seconds)
for HDD you need the solution from @sunarowicz (external power-supply for the hdds)

Power button is so confusing because the board is “on” before the 10 count but if you let it go at the wrong time it turns back off. I would be happy with just reprogramming the power button so I don’t have to hold it for 10 seconds.
Does anyone know if that can be done?
Just for your info. If you bridge powerbutton you may encounter problems like a bootloop.

Sorry for my answer in old topic, but the problem regarding to it
I have compiled kernel 4.19.16 (branch 4.19-main) from @frank-w repo. Kernel config not changed. What I do:
./build.sh importconfig
./build.sh build
./build.sh pack
and then extract kernel archive to SD card (boot part on boot partition, and root on root partition). When I run “shutdown -h 0” I got kernel panic. acpid is not installed. I use slackarm distro.
Kernel panic output:

crash seem to happen in framebuffer-console, have you a monitor connected? have you same problem on “poweroff”-command?
have you problem on another ḱernel-version?
Yes. I have connected monitor via hdmi and serial console too. On “poweroff” it is the same kernel panic. I check what happens on kernel 4.16 and back with the result.
i have tested on my debian-system (also actual 4.19.16) with installed acpi, no crash…can you enable drm-debug (drm.debug=0x7) via your uenv.txt?
where do you get your image or how have you build it?
you see crash only on serial, right? does it happen after a clean boot? or do you have errors on boot too? anything done between bootup and poweroff?
I haven’t installed acpi on my slackarm. Yes, sure. I can enable drm-debug if you can tell me how.
I’m build the kernel on Virtual Machine with Ubuntu 16.04 using your build.sh script.
I see the crash on hdmi and serial console too. But only from serial console I will be able to put it here 
On kernel 4.16.18 I have the same kernel panic on poweroff and shutdown commands 
just add “drm.debug=0x7” to your bootargs (uboot-config uEnv.txt)
i expected that fbcon is closed so you see the error only on serial…as you said, you see it on hdmi too fbcon is not killed at this moment
you do not get the last “Power down”-mesage right? means your device stays powered on
this is how it looks on my debian-system
