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.
