Hello I just realized that my HP laptop lost the half battery capacity. Take a look : markand@Melon ~ $ acpiconf -i 0 Design capacity: 4400 mAh Last full capacity: 2132 mAh Technology: secondary (rechargeable) Design voltage: 14400 mV Capacity (warn): 200 mAh Capacity (low): 100 mAh Low/warn granularity: 100 mAh Warn/full granularity: 100 mAh Model number: Primary Serial number: 02109 2009/08/11 Type: LIon OEM info: Hewlett-Packard State: charging Remaining capacity: 0% Remaining time: unknown Present rate: 3061 mA Voltage: 15751 mV Design capacity: 4400 mAh Last full capacity: 2132 mAh I'm guessing if this should be, the laptop has only about 8 months and I don't use it much on battery, only around one day per week and not until the battery is empty. If I remember correctly my old laptop didn't lost so much of capacity in a few months like that. My question is : how long a battery should live ? is anything could bring down the battery sooner ? I hope the next battery wont be too much expensive and will live more.. Cheers, -- Demelier David
