# Lenovo IdeaPad 5 Pro / XiaoXin Pro 14 GT (14IAH10)
This module provides configuration common to all Arrow Lake (Core Ultra 200H
series)-based devices and rectifies a few quirks with the system that are mostly
all caused by firmware or BIOS bugs. While the solution isn't perfect, the
laptop is decently usable with these tweaks, including networking and speakers
output.

# HACK: Fix the infamous "Unable to change power state from D3cold to D0"
# error when resuming the system from a suspended state, by _completely_
# disabling PCIe port power management and thereby preventing the Wi-Fi
# adapter from turning off at all.
#
# This is theoretically bad from a battery life standpoint, but it's
# necessary until Intel ships a functioning firmware release that doesn't
# suffer from this issue. In my real-world testing this doesn't seem to
# have caused a noticable decrease in battery life, however.

# See Intel's (non-)response regarding this issue with this exact model at:

# Last tested to be necessary on ucode version 98 — this might no
# longer be necessary for newer firmware releases!
