Hi,

Tonight I've forgot to plug my T42 (with 9-cell battery) to the power
and left it open.  Of course, battery discharged completely :(

This morning I've found that 'last full capacity' as reported by acpi
dropped from about ~70W down to ~57W:

akhavr@t40 /tmp $ cat /sys/devices/platform/smapi/BAT0/last_full_capacity
57200

Is this an electronic issue and that could be reset somehow or that's
the cells where drained so much that their maximum capacity suffered?

Thanks in advance.
