# Fujitsu Lifebook A555 (Broadwell) battery fix v2 by Ressetkk
# This is alternative patch for Fujitsu Lifebook A555 since the original B1B2 method did not work in first case - the _BIX/_BIF method returned wrong values.
# I’ve decided to use offsets and RECB/WECB methods for all 16-bit+ fields and it worked somehow.
# If this patch does not work for you try to use another one

# Rename all needed fields
