    need fujitsu e734 bios,bricked after battery update

    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?

        Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
        by Bowline
        My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

        Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

        My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
        The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
        I have tried multiple different Dell power adapters. My Dell...

        ASUS X571 no power : battery issue?
        by mkdj
        Hello everyone,

        Mark and model: ASUS X571
        Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.

        Tests already made:
        - Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
        - I have removed...
