First, let's make sure it is the battery.  With AC plugged in, remove the
battery and check if the sensor returns -128/128 or an ENXIO error.  If it
does, then the sensor really does belong to the battery.  Plug the battery
back, wait the usual 10s to 12s, and check again.  The sensor should be
back, and should read the temperature of the battery.

Assuming the sensor belongs to the battery, then you need to find out
whether it is broken or not.  I'd suggest asking around for other R60 users
with batteries to see if they have the same problem (and updating to the
latest BIOS and EC *first*), and also asking Lenovo about it.

If it is not broken, it is possible that you *could* have a dangerous bomb
in your hands.  Ask Lenovo about it.

We query the EC for that temperature, there is basically *zero* chance of a
bug in thinkpad-acpi/ibm-acpi for this if the other sensors are working.  It
is either a battery defect, a Lenovo EC firmware bug, or Lenovo changed the
way the firmware works for that particular sensor.
