Funny battery configuration with 8-stable: remi# acpiconf -i 0 Design capacity: 279 mAh Last full capacity: 279 mAh Technology: secondary (rechargeable) Design voltage: 10800 mV Capacity (warn): 14 mAh Capacity (low): 3 mAh Low/warn granularity: 100 mAh Warn/full granularity: 100 mAh Model number: Primary Serial number: 00784 2006/10/04 Type: LIon OEM info: Hewlett-Packard State: high Remaining capacity: 99% Remaining time: unknown Present rate: 0 mA Voltage: 12424 mV The battery is declared as 55 Wh, which would correspond to 5.1 Ah (probably 3 x 2 x 18650 cells). When unplugging the AC supply, I get: remi# acpiconf -i 0 Design capacity: 279 mAh Last full capacity: 279 mAh Technology: secondary (rechargeable) Design voltage: 10800 mV Capacity (warn): 14 mAh Capacity (low): 3 mAh Low/warn granularity: 100 mAh Warn/full granularity: 100 mAh Model number: Primary Serial number: 00784 2006/10/04 Type: LIon OEM info: Hewlett-Packard State: discharging Remaining capacity: 98% Remaining time: 0:08 Present rate: 2064 mA Voltage: 11870 mV I'm not sure whether the "remaining time" is realistic or not. In the past (FreeBSD 6.x), it used to immediately shut down when unplugging AC since the battery state was always unknown. Now, FreeBSD 8.x is the first version that actually manages to survive running on batteries. This is an HP/Compaq nx6325. Any clues how to fix these values? -- cheers, J"org .-.-. --... ...-- -.. .
