need fujitsu e734 bios,bricked after battery update

[jokoxe5284]

Hi guys! I am a beginner IT guy who sadly bricked his laptop. My fujitsu E734laptop is hard bricked after I try to install battery Firmware Update. Laptop is all dead, non of small LEDs are blinking. I bought myself a cheap ch341a programmer so I can rewrite it. Please have a little patience, it is very frustating that my little laptop is gone. What information do I need to post here so you can provide me a link. I read I need 2 flash too chips. Thank you for takin your time, and please excuse me if I my post is out of the subject or wrong.

Use your Ch341a programmer and dump the bios from the machine as is, corrupted or not it doesn't matter. Must be two chips - 4MB+1MB.
Edit: You can also attach the file used in your attempt to update the battery firmware (?), is it full bios update or something else, are you sure it was intended exactly for your model?

Here is the program I used to upgrade the battery. It starts everytime I start the laptop. I will upload the two chip readings, do I need to desolder them or they will be just fine reading on the board?
