Note:

If in your system bash:

Replace #!/bin/sh with #!/bin/bash in script

###If this dosent run well and create a grub config do the steps given below (tried in Ubuntu 20.04.2):

1. After downloading the script, you need to run sed -i -e 's/\r$//' ./thinkpad-e15-gen2-firmware-fix.sh to strip out ^M in the file

2. You need to run the following commands to install acpidump

sudo apt-get update

sudo apt-get install acpidump

thanks to @sysintelligent from lenovo forums for this .

Arch

Make sure you have acpica installed (pacman -S acpica) and run thinkpad-e15-gen2-firmware-fix_arch.sh instead. Tested with kernel 5.12.10-arch1-1. Normally the ^M aren't present in this script, but if you get an error related to this then see above. NOTE: The script uses #!/usr/bin/bash as a crunchbang since it's the common Arch location for bash. You have to change it if you use another interpreter/it is located elsewhere!

fedora

sudo dnf install acpidump -y Run the script named thinkpad-e15-gen2-firmware-fix_fedora.sh and it should work . Tested in fedora 33 with 5.10.18 kernel.
