  Go to bios change storage > sata/nvme operation > AHCL/Nvme and also turn-off secure boot.

  
  

  
  
  
  
  

• Download & Install the kernel file 5.4.0-84-generic

• Hardware enablement: 

  sudo apt-get install --install-recommends linux-generic-hwe-20.04

• BIOS Update:

                                          sudo apt install fwupd

  			 sudo service fwupd start
  			 sudo fwupdmgr refresh

                                          fwupdmgr get-devices

  			 fwupdmgr get-updates
 			 sudo fwupdmgr update

• Install the linux-headers and linux-extra packages using the commands

                                            sudo apt update.

                                            sudo apt install linux-headers-5.4.0-84-generic

                                            reboot

• Now switch to 5.4.0 kernel 

  note: Bios settings may need to be re-verified/changed after upgrading the bios.

  (If you are facing network issues then install the network drivers)

  - After booting into the linux 5.4.0 kernel use the command

  lspci

  - Get the info of the LAN port and search for the appropriate drivers.

  note: If you did not find any  info about you LAN port then it might be a hardware issue. 
  

  - boot into another kernel (with network connectivity) and download the drivers (here are the required drivers for our case) - switch to linux kernel 5.4.0-84 and install the drivers.
