Thinkpad X121e - Battery Threshold

I'm trying to use TLP to set the battery tresholds for my X121e but can't seem to get it to work. As the X121e isn't supported by tp_smapi I believe TLP instead uses tpacpi-bat to achieve this. Dmesg shows lots of occurances of

[ 6471.594319] acpi_call: Cannot get handle: Error: AE_NOT_FOUND

I did notice that my battery device path differs from the one in the dsdt file

~ $ cat /sys/class/power_supply/BAT1/device/path                         
\_SB_.BAT1

~ $ cat dsdt.dsl | grep \\\\_SB\.PCI.*HKEY -o | uniq
\_SB.PCI0.LPCB.EC.HKEY

there are also some acpi errors present during boot that I noticed

Here are the full dmesg and dsdt.dsl files. Thanks for any assistance!

P.S. I wasn't quite sure if this go in the kernel or laptop issues section, please feel free to move the thread accordingly.
