[Pkg-utopia-maintainers] Bug#463878: considers a battery charge of 0 to be 100%

[Joey Hess]

Package: hal
Version: 0.5.10-5
Severity: serious

My battery is empty:

joey at kodama:/sys/class/power_supply/CMB1>cat charge_now 
0
joey at kodama:/sys/class/power_supply/CMB1>cat charge_full
7800000
joey at kodama:/sys/class/power_supply/CMB1>cat charge_full_design 
7800000

hal, perversely, thinks this indicates it is 100% charged:

  battery.charge_level.current = 0  (0x0)  (int)
  battery.charge_level.last_full = 7800  (0x1e78)  (int)
  battery.charge_level.percentage = 100  (0x64)  (int)
  battery.charge_level.rate = 0  (0x0)  (int)
  battery.current = 275  (0x113)  (int)
  battery.present = true  (bool)
  battery.rechargeable.is_charging = true  (bool)
  battery.rechargeable.is_discharging = false  (bool)
  battery.reporting.current = 0  (0x0)  (int)
  battery.reporting.design = 7800  (0x1e78)  (int)
  battery.reporting.last_full = 7800  (0x1e78)  (int)
  battery.reporting.technology = 'Li-ion'  (string)
  battery.reporting.unit = 'mAh'  (string)
  battery.technology = 'lithium-ion'  (string)
  battery.type = 'primary'  (string)
  battery.vendor = 'Fujitsu'  (string)
  battery.voltage.current = 7016  (0x1b68)  (int)
  info.capabilities = {'battery'} (string list)
  info.category = 'battery'  (string)

hal seems to only do this once the battery reaches 0% full, or the charge_now
reaches 0. For other low charge levels like 1%, it's accurate-ish.

This does not seem to be the same as the other bugs like #462723.
Not sure though.

This causes data loss, because programs that watch for the battery to reach
0%, and put the machine to sleep, fail to do so, and the machine loses all
power and dies. (Just happened to me.) Since that probably only occurs under
unusual configutations, I'm only marking the bug serious, not grave.
