--- Comment #37 from Lan Tianyu <tianyu....@intel.com> 2011-06-27 06:59:42 --- Current the sysfs works correctly. If upower queried power_now, it would get correct status. But it didn't. I guess it maybe a upower issue. Do you use the latest version? I use the 0.9.1 version and test it on my laptop. But it's battery is not sbs. Do the same operation. "energy-rate: 0W" will also happen sometime while the sysfs power_now is correct. But after 30 seconds, upower updated data correctly. (In reply to comment #31) >- Battery is discharging at boot. upower --monitor-detail running in >background. upower gets regular updates every 30 s, but it indicates >"energy-rate: 0 W", so it doesn't provide any estimate for discharge time. >Status and rate of discharge is sysfs appear to be correct and coherent with >procfs: (In reply to comment #34) > > Did "energy-rate: 0 W" happen without the test patch before? > No: before this patch energy-rate used to be the same value as current_now, > and > the same was reported in power_now. Now power_now seems to be correct, while > upower has zero rate. I find the upower depend on the "/sys/class/power_supply/BAT0/current_now". In the patch https://bugzilla.kernel.org/attachment.cgi?id=63262, I remove the current_now and current_avg from the sysfs when the battery unit is "mW". The current_now and current_avg should not be exist at that time. But this caused the "energy-rate: 0 W". The upower work abnormally. Hi Matthew Garrett, I find you removed the current_now in the battery.c when the unit is "mW". Commit b137b9942a07843c64a934cfdb7d43155e507e13. Have you seen such problem?
