Should I be worried?
My battery power doesn't last long (~1hr), could this be the reason?
How can I fix this (if it has to be fixed at all)?

  • On the second line of your description, says "My doesn't last long" ... What do you mean? – Kevdog777 Dec 27 '13 at 12:20
  • Edited, I meant that my battery lasts a very short time (<1hr), and that it used to last longer (multiple hours). It could be either that it's permanently damaged, or that it's being drained by something - possibly this (actually this sounds kind of impossible, but that's why it's just a speculation). – jcora Dec 27 '13 at 12:33
  • you can manually fix it from powertop or create systemd service to do that for you on boot. If you need help with later method, let me know... – Edward Torvalds Mar 3 '19 at 9:46

A single session fix that I found is as follows. Go to the Tunables tab. There, one of the options will be : Enable Audio codec power management with the value Bad. Press Enter to change it to Good, and watch as your power consumption drops to a more bearable level

But this fix has to be done every time you reboot. I wish there were a way to make this permanent.
