| How can I reliably get battery status on pinebook |

Hi,
thanks to the great Q4os developers I now have a quite decent Debian Stretch system running. After I managed to flash the eMMC with Q4os I simply editet sources.list to point to Stretch instead of Jessie and did a dist-upgrade. I needed to fiddle a bit with the graphics since X was lost but rebuilding libump and xf86-video-fbturbo under Stretch did the trick. (I'm a Debian developer and might consider creating at least an official libump package - need to check the license of fbturbo whether it is acceptable in Debian.)
I now try to get some reliable information about the battery status. I'm using xfce4 but the battery plugin always says the battery is empty (even if I get a desktop notification that the battery is full when plugging in power adapter.
The command acpi does not work.
How do others check the battery status on pinebook?
Kind regards
Andreas.

Just in case anyone else is having a similar problem.
My Pinebook has had a history of just shutting off at random occasions after a couple of months light use. I had put this down to the development status of the system, however, it was getting more and more common, occasionally refusing to boot, so much so I was starting to be convinced it was hardware.
I opened the thing up and removed the tape covering the cable from the battery to the mainboard. The left hand side of the socket on the board was broken and the connector came away with the tape.
The bend in the power cables meant it would not stay in position, and I didn't want to blob some epoxy on the connector in case of future upgrades. So, several strips of tape to route the battery power leads in position and reseating the connector and it now works perfectly. I had been worried it would be a dodgy capacitor somewhere, but a relatively simple fix.
One thing I did notice with the system when I thought it was software based was that while I was looking at the system logs in an ssh session is that the USB system lost power and came back.
Anyway, if anyone else has a similar problem with random system crashes / power offs, it may be worth a look.

| Help debug my pine64A+ ubuntu/plex hangs |

Hello,
I'm trying to understand why my pine64+ keeps hanging after 3 days or so.
I'm using it as Plex Server (direct play) and it's works very well but when it became unreacheable from the network and I suspect the board hangs. How can I debug the problem? which logs can help me?
Maybe a temperature problem?
Any hint would be great.
I've installed an ubuntu and plex as this guide says: http://jez.me/article/plex-server-on-a-pine64-how-to. In fact I've a rpi-monitor installed too and sometimes the temperature is near 90ºC but normally is 70-75ºC in playing mode.
thanks in advance.

How to set the Power Off key binding in i3wm for the Pinebook |

Greetings,
The purpose of this blog post is to detail the steps necessary to set the Power Off key-binding for the Pinebook in i3 window manager. We don't want the Pinebook to come crashing down if we accidentally touch the poweroff button -- so we'll set a key-binding that makes sense requiring at least two other keys , for instance the $mod key and the Shift key. The following key-binding should bring the system down cleanly ( and power off properly ) without prompting for a password:
$mod+Shift+XF86_PowerOff
The key-binding will be placed in the i3 config; but I'm getting ahead of myself. The first step is to build the poweroff script in /usr/local/sbin/
Pb_poweroff.sh
The simple script above should be placed in /usr/local/sbin/ and should be made active with the following commands:
sudo chown root:root Pb_poweroff.sh
sudo chmod 0754 Pb_poweroff.sh
The next step is to place a rule file in /etc/sudoers.d/ so that the command trigger will not prompt for the sudo password when the key-binding is pressed. Creat the following rule file in /etc/sudoers.d/ :
Pb_power_rule
Code: # Pb power rule
Cmnd_Alias PBPOWEROFF=/usr/local/sbin/Pb_poweroff.sh
ALL ALL=NOPASSWD: PBPOWEROFF
Place the above rule file in the /etc/sudoers.d/ directory and activate with the following commands :
sudo chown root:root Pb_power_rule
sudo chmod 0440 Pb_power_rule
The last step is to place the following bindsym entry in the i3 configuration ~/.config/i3/config , in your home directory:
bindsym $mod+Shift+XF86_PowerOff exec sudo /usr/local/sbin/Pb_poweroff.sh
Place the above bindsym entry somewhere near the end of your i3 config after the "resize" and before the "bar". The configuration file is ~/.config/i3/config
Activate the key-binding by either pressing $mod+Shift+c to re-read the config, or $mod+Shift+r to restart i3wm.
Theory
Pressing the Pinebook power button returns scancode 124; key-sym XF86_PowerOff. This by default does nothing in i3wm; unlike other OS window manager | desktops , which typically pulls up the shutdown dialogue.
With our keybinding in effect the Pb_poweroff.sh script will be called with sudo, and because the Pb_power_rule file exists in /etc/sudoers.d/ the command trigger will not prompt for the password, but the poweroff command will simply take effect: while holding down the mod key, and the Shift key together, press the power button and the i3 window manager will exit and the system will cleanly shutdown and power off.
