Hello! Over the last months I've had a "problem" regarding battery status on my laptop which has been running FreeBSD CURRENT in order to have a working Intel driver (Haswell). My problem/question is that when I boot the laptop with a fully charged battery and it is still connected to a power source, acpiconf reports that the battery is discharging, even if it is not: [andersbo@freebsd-acer: it]$ acpiconf -i0 Design capacity: 4605 mAh Last full capacity: 3523 mAh Technology: secondary (rechargeable) Design voltage: 11400 mV Capacity (warn): 245 mAh Capacity (low): 192 mAh Low/warn granularity: 53 mAh Warn/full granularity: 3278 mAh Model number: AC14A8L Serial number: 13475 Type: LION OEM info: LGC State: discharging Remaining capacity: 98% Remaining time: unknown Present rate: 0 mA (0 mW) Present voltage: 12619 mV However, if I do discharge the battery and then charge it up to full again, acpiconf correctly reports battery status as "high": [andersbo@freebsd-acer: it]$ acpiconf -i0 Design capacity: 4605 mAh Last full capacity: 3584 mAh Technology: secondary (rechargeable) Design voltage: 11400 mV Capacity (warn): 245 mAh Capacity (low): 192 mAh Low/warn granularity: 53 mAh Warn/full granularity: 3339 mAh Model number: AC14A8L Serial number: 13475 Type: LION OEM info: LGC State: high Remaining capacity: 100% Remaining time: unknown Present rate: 0 mA (0 mW) Present voltage: 12823 mV Last Thursday I updated the sources to ALPHA2: [andersbo@freebsd-acer: it]$ uname -a FreeBSD freebsd-acer.local 11.0-ALPHA2 FreeBSD 11.0-ALPHA2 #1 r301745: Thu Jun 9 20:25:35 CEST 2016 root@freebsd-acer.local:/usr/obj/usr/src/sys/GENERIC amd64 Do you have any tips on how to fix this little "problem?" Thanks in advance. Anders
