現象

満充電状態にして、100%充電状態であることを確認後、電源を外して、ラップトップの画面を閉じて持ち歩いたり、机に放置しおく
その後まったく使ってないのに残容量 0%だったり、少しだけ残ってる状態になる
一日中、バックの中が生暖かく保たれる

= 準備 =

apt-get update
sudo apt-get build-dep linux-image-$(uname -r)

mkdir build
git clone git://kernel.ubuntu.com/ubuntu/ubuntu-bionic.git
git checkout -b Ubuntu-4.15.0-36.39
chmod a+x debian/rules
chmod a+x debian/scripts/*

海外出張によく行くプロジェクトがあって、その時に身につけた方法をメモ
