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?


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.

  • Please try another ac adapter with same the connector type and check the output settings. I believe your installation of Ubuntu 16.10 has got nothing to do with charging.

    Very interesting. I've never heard of this kind of problem... or thought this might even be possible.

  • Very odd, as @MadMike pointed out. Have you considered using a non-ubuntu kernel, perhaps one of the newer mainline kernels? The only feasible explanation I can think of is that there is a conflict with the power management from the kernel, which perhaps actively stops charging (if such a thing is possible)? Do you still have windows as a dual-boot and, if so, does the charging still work under Windows? That'd be an easy way to tell if it's a very-conveniently-timed hardware issue.

  • Please edit the output of grep ACPI /var/log/syslog into your post. Thank you for helping us help you!

  • @Aargonian I don't have dual-boot any more. The problem started when I installed Ubuntu 16.10 as a dual-boot, but it got worse when I uninstalled windows and installed KDE. I really don't understand what is going on. I'll try to charge my laptop with a new charger to discard that problem.

The charger was broken. I just bought a new one and everything works fine now. Thank you.
