Many laptops have the capacity to add a second battery, sometimes instead of a CD/DVD or extra hard drive in a bay. The above output doesn't indicate that there are two fitted, just the capacity for managing two in the ACPI/BIOS. 'bat0' and 'bat1' used below are not valid battery descriptors, specify only '0' or '1'. Yes, acpiconf(8) should be a lot clearer about that. Specifying any invalid string always gets you info for battery 0, ie is equivalent to 'acpiconf -i0', which is why the results below are both the same down to the serial numbers and present charge rate and voltage. If 'acpiconf -i 1' shows other than 'Device not configured' you might indeed have some issue. cheers, Ian > [root@dlaptop ~]# acpiconf -i bat0 > Design capacity: 5200 mAh > Last full capacity: 4677 mAh > Technology: secondary (rechargeable) > Design voltage: 11100 mV > Capacity (warn): 520 mAh > Capacity (low): 157 mAh > Low/warn granularity: 52 mAh > Warn/full granularity: 52 mAh > Model number: DELL PT43693 > Serial number: 37449 > Type: LION > OEM info: Samsung SDI > State: charging > Remaining capacity: 77% > Remaining time: unknown > Present rate: 2692 mA (33359 mW) > Present voltage: 12392 mV > > [root@dlaptop ~]# acpiconf -i bat1 > Design capacity: 5200 mAh > Last full capacity: 4677 mAh > Technology: secondary (rechargeable) > Design voltage: 11100 mV > Capacity (warn): 520 mAh > Capacity (low): 157 mAh > Low/warn granularity: 52 mAh > Warn/full granularity: 52 mAh > Model number: DELL PT43693 > Serial number: 37449 > Type: LION > OEM info: Samsung SDI > State: charging > Remaining capacity: 77% > Remaining time: unknown > Present rate: 2692 mA (33359 mW) > Present voltage: 12392 mV > > -- > Andre Goree > andre@drenet.info
