battery problems

[Joel Stanley]

Hi All,

on a B1 system running 303 with q2b76;

$ cat /sys/class/battery/psu_0/capacity_percentage
cat: /sys/class/battery/psu_0/capacity_percentage: no such device

$ ls -1 /sys/class/battery/psu_0
capacity_percentage
current
name
power
status
status_cap
subsystem
technology
temp1
temp1_name
temp2
temp2_name
type
uevent
voltage

the battery does not hold any charge, is the 'no such device' message related?

If so, is there any way to charge the battery? I have read about using
a B2 unit to recover a dead B1 battery.

Regards,

Joel
