Summary: Cannot display status of two batteries in lenovo
thinkpad
Product: ACPI
Version: 2.5
Kernel Version: 2.6.35.4
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Battery
AssignedTo: acpi_power-batt...@kernel-bugs.osdl.org
ReportedBy: ha...@gentoo.org
Regression: No
On my lenovo t61 laptop, I have an extra battery in the bay slot. I always can
only see the status of one battery (no matter if through the old proc interface
or the new one). See output of acpi:
Battery 0: Full, 100%
Battery 1: Unknown, 99%
It switches the battery it correctly shows, e.g. if bat1 is discharging, it
shows bat1 correctly and bat0 as unknown, if bat0 is discharging then it's the
other way round.
This is from dmesg:
ACPI: Battery Slot [BAT0] (battery present)
ACPI: Battery Slot [BAT1] (battery present)
