No battery critical warning on Thinkpad t42

[m.ehinger at ltur.de]

Hello,

i recognized that an my Thinkpad T42 i get no battery critical warnings! All i get is a battery low state.

hw.acpi.battery.state becomes 1 at discharge, 2 at recharge and 0 at full.

I get ACPI notifies from CMBAT at 4% and 38%  with hw.acpi.battery.state: 1 and at 100% with hw.acpi.battery.state=0.

Is that the correct behaviour?

Is there an default action when battery becomes critical?

I'm running 7.0-Current (Jul 28).

Thanks

Maik
