[Pkg-utopia-maintainers] Bug#463740: reports battery is discharhing when there's no ac power

[Joey Hess]

Package: hal
Version: 0.5.10-5
Severity: normal

This is what lshal shows for my laptop (fujitsu p7120) when power is
plugged in:

  battery.rechargeable.is_charging = true  (bool)
  battery.rechargeable.is_discharging = false  (bool)
  ac_adapter.present = true  (bool)

This is what it shows when power is not plugged in:

  battery.rechargeable.is_charging = true  (bool)
  battery.rechargeable.is_discharging = false  (bool)
  ac_adapter.present = false  (bool)

Yep, it's magically charging with no AC power or other power source.
Nice trick. ;-)

Interestingly in both cases, I see this:

joey at kodama:/sys/class/power_supply/CMB1>cat status
Discharging

That seems to be because the battery is currently 100% charged:

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

So I have no idea why hal thinks it's charging..

The relevant code looks ok:

        /* STATUS: Convert to charging/discharging state */
        status = hal_util_get_string_from_file (path, "status");
        if (status != NULL) {
                if (strcasecmp (status, "charging") == 0) {
                        is_charging = TRUE;
                } else if (strcasecmp (status, "discharging") == 0) {
                        is_discharging = TRUE;
                }
                hal_device_property_set_bool (d, "battery.rechargeable.is_charging", is_charging);
                hal_device_property_set_bool (d, "battery.rechargeable.is_discharging", is_discharging);
        }

If I kill and restart hald, it gets the right values:

  battery.rechargeable.is_charging = false  (bool)
  battery.rechargeable.is_discharging = true  (bool)
