[ltp] problems with slice battery & Ubuntu

[Mark Wotton]

G'day all,

I'm having a bit of a trouble getting my slice battery to work. It's
worked in the past, but not recently: I suspect I may have drained it
down to zero. The problem is that it won't charge now.


rhino =E2=9E=9C  ~  cat /proc/acpi/battery/BAT0/info

and, confusingly:

rhino =E2=9E=9C  ~  acpi
Battery 0: Unknown, 0%
Battery 1: Charging, 86%, 00:19:06 until charged

I am getting these odd messages in /var/log/syslog:

Dec  8 14:15:53 rhino kernel: [191707.237114] ACPI: Deprecated procfs
I/F for battery is loaded, please retry with CONFIG_ACPI_PROCFS_POWER
cleared


running Ubuntu 12.04 on a t410 - would very much appreciate any
insight into debugging tactics.

cheers
Mark
