Every time I turn on my computer, I see a message saying something like:
Your battery may be old or broken.
I am already aware that my battery is bad. How do I suppress this message?
Maybe these instructions will help you to get rid of that message.
Added instructions from the link, Alt+F2, then type in
Or a single command:
This worked for me:
If you have a machine with Windows as a dual-boot option, you can boot to Windows and let the battery recharge here. When the battery has recharged for a while, you can boot to Ubuntu and let it do the rest.
In ubuntu mate, gconf editor is not installed by default and installing it will not help.
Instead, you should use dconf editor. You will need to navigate to /org/mate/power-manager and then untick "notify-low-capacity."
