Ubuntu – Battery only charging when shutting down by holding the power button or in suspended mode

I have an ASUS-UX305F zenbook. Everything was working fine with Windows 10 until I recently installed KDE 16.10 (I removed Windows 10, so it is not a dual boot) and now I can't properly charge my laptop:

mat@matlaptop:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.10
Release:    16.10
Codename:   yakkety

The only way I can charge it is:

• by holding the power button until my laptop shutdowns (a regular
  shutdown doesn't help)
• when the laptop is in suspended mode (e.g. by running systemctl suspend)

If my laptop is active and I plug the charger in the led that indicates if the battery is charging starts to blink a few times than it turns off. This is what the power command returns (while the charger is plugged):

mat@matlaptop:~$ upower -i /org/freedesktop/UPower/devices/battery_BAT0

Is there any way to fix this?

EDIT:

The baterry also charges when the laptop is in suspend mode (systemctl suspend)!

As requested by @ElderGeek, here is the output from the grep ACPI /var/log/syslog command.
