And this is the Voltage History screenshot, took a few seconds later. Notice how there is no corresponding sudden change—it even rises a little around the time the Charge fell down.
Another interesting tidbit is that the battery model on this laptop has a little charge monitor: a small button and five green LEDs in a row. When you press the button the LEDs light up according to the charge level. This works even when the computer is off— actually, even on the removed battery, so I assume it's done via some hardware inside the battery. What's strange is that this is also affected: when the PM shows the critical battery warning the LEDs too suddenly go from five to one. Perhaps there's something written via ACPI to the battery? At first I though the battery might be broken, but the BIOS says it's functioning normally. ** Attachment added: "Voltage History.png" http://launchpadlibrarian.net/9208707/Voltage%20History.png -- power management applet seems very screwy https://bugs.launchpad.net/bugs/137951 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
