para tentar resolver o problema vou começar por desativar a função de gestão de energia hybrid-sleep.target:
sudo systemctl mask hybrid-sleep.target

lsusb | grep -i bluetooth
dmesg | grep -i bluetooth
dmidecode -t0

descarregar este driver: https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/g4wh01ww.exe

innoextract g4wh01ww.exe
cd app
find . -name '*.inf' -type f -exec grep -A5 -i 21e6 -- {} + | grep .hex

e o resultado:

problema da máquina acordar logo a seguir a suspender:
echo EHC1 > /proc/acpi/wakeup
echo EHC2 > /proc/acpi/wakeup
echo XHCI > /proc/acpi/wakeup

cat /proc/acpi/wakeup
