Output of dmidecode

On my convertible TX300CA from Asus the battery in the dock isn't recognized. This limits the runtime to 1.5 hours.

debug.patch

Sorry for later response. Please apply the debug patch and rebuild kernel. After booting, run "grep . /sys/class/power_supply/BAT0/*" and attach the dmesg. The debug patch is to print the value of state returned by Bios.

I have got a TX300CA too, and the same problem, and I'm available for making some tests on it if you need to, guys.

Comment 15 Lan Tianyu 2014-05-21 07:37:29 UTC 
Hi, Sorry for later response. After reviewing the bug, I found I went a wrong direction. In the ACPI table, I only find one Battery device(BAT0) that we see. About the second battery, it wasn't shown in the DSDT table and so this is not a ACPI bug.
