Bug#593096: Battery discharge indicator no longer works in recent kernels
I have a Dell XPS M1210 laptop, which has a LED battery indicator.
Previously, whenever the laptop was running out of battery, the
battery LED would start blinking orange, giving some time to connect
the power or do a graceful shutdown. Some time ago (unfortunately, I
can't give the exact time, it feels like it might have been 2-3 months
ago) this behavior has changed, and now the LED never warns about the
battery running out. I already had a couple of accidents, where I
would forget to connect it to power and laptop would die on me,
leading to loss of unsaved work, etc.
I understand that it probably has something to do with ACPI subsystem,
however I have very little clue on how all this stuff (ACPI, battery
state notifications, activation of LEDs, etc) works together, so I
would need some guidance to come up with good debugging info.
