Add Support for L430

[clentfort]

Hi,

I am having issues with tpacpi-bat on my L430. The problem is somewhat odd!
When I set a start threshold it will effect the start and the stop threshold, setting the stop threshold has no effect what so ever! It tested this issue with a stand alone version of tpacpi-bat and the version that ships with TLP. I'm running Arch 64 bit.

Hi,

there is complete support for the L430 already.

What you observe is a problem when reading the threshold values, see #37 and TLP FAQ please.

as the bug is actually in the BIOS, there is no known workaround.

[clentfort]

Well either I have still not understood how this is supposed to work or it does not work.

Say I run my laptop on battery and drop to 35%, start threshold is set to 40, stop is set to 80. I attach the laptop to a powersource and it charges to 40% and then stops. To my understanding it should charge up to 80% and not stop at 40%!

[linrunner]

Yes, it should charge from 35% to 80%.

Maybe the wrong behaviour comes from your experiments. Refresh the thresholds with:

# tlp setcharge 45 80

If it still doesn't work, you're out of luck because there is no way for tpacpi-bat to fix the BIOS. Go blame Lenovo.

thanks, linrunner.

yea, clentfort, i cant fix BIOS bugs. other folks report L430 working for start/stop, except the --get reports incorrectly, as indicated in #37. if yours isnt working, it seems to be limited to your laptop.

[clentfort]

Seems it was a typical case of the user is the problem. For what ever reason it works now! :) Thanks for your quick responses anyway!
