<p><b>New page</b></p><div>Hi,<br />
<br />
To answer your questions: <br />
<br />
I usually power the system using MeanWell GST25A05 5V 4A power supply. <br />
<br />
1) When I plug the power supply into X820 and RPi is powered from X820 via 2-PIN power cable (and also connected via USB of course) - reboot does not work. <br />
<br />
2) When I plug the power supply (the same MeanWell) into RPi and X820 gets the power only from RPi via USB (2-PIN power cable is not used) - reboot works fine. However, there are 2 problems with this configuration<br />
i) power button on X820 does not work<br />
ii) RPi periodically reports an undervoltage warning (hwmon hwmon1: Undervoltage detected). This does not happen when I use a different SATA to USB dongle instead of X820 or when I power the system via X820.<br />
<br />
Please let me know if you want me to run an additional experiment<!-- migrated from Comments; original IP: 84.108.144.120 --></div>84.108.144.120
