GNOME Bugzilla – Bug 607028
laptop battery time remaining outrageously inaccurate
Last modified: 2012-07-17 00:02:45 UTC
On many different laptops, the time remaining seems to vary wildly during a session, typically depending on power use. That is, when CPU usage is high, remaining time drops drastically while idle makes it jump back up again. This behavior is conceptually correct, but the time seems to vary too quickly. See <https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/120258> for much more information. (Upstream bug report created at request of Richard Hughes.)
This problem is still very annoying to me on Lucid. Unplugging the power throws a window that tells me: "Laptop battery critically low - Computer will suspend very soon unless it is plugged in". Clicking OK suspends the computer. Furthermore, I can't even turn off suspend/hibernate/shutdown from the battery preferences, so this is a really annoying usability issue (especially since hibernate/suspend has been severely broken for who knows how long on Ubuntu on my computer).
Not even a comment about why this is "NOTGNOME"? Where should we look instead?
