Make sure the laptop is on mains
Fire up the Phoenix flash program
Direct it to flash from a file (which is on your USB stick) when asked
Let the program run the update
It will shutdown your machine and then it will reboot and run the BIOS flash
Make sure you do not touch the laptop whilst it is doing this or switch it off in any way
If the program asks you if you want to update the BIOS or any other question where the answer must be yes then follow what it is asking you to do.
It will take all of about 2 to 5 mins and once it is done will boot your machine to the OS startup.
Let us know how you get on please and if there is anything you don't understand then please ask. I will stay on this side of the forum looking for any input from you. Also if you want we can go over to the conversation side to make things easier. I've sent a message to start the conversation just in case
