    Hi. So finally today I received the BIOS USB Programmer and I successfully wrote the latest ZRQ.fd into the chip and tried to power on but this time the laptop just gave a power flash like turned on for one second than went off. After that I again wrote the backup bios file into chip which I saved before and now the laptop is again behaving the same. So what I understand so far is the bios file which is not compatible. I need find the exact bios file. Help please.

    The only binary FD files that we as users have access to, are those extracted from the compressed files at this link https://www.acer.com/ac/en/US/content/support-product/4846?b=1

    You should probably re-record the EC bios as well.

    Which chip holds the EC Bios ? Can you help me identify ?

    It looks like it's the U14 (ec) and U34 (MAIN) chip.

    Thank you. I found U34. Which is here


  • ShaharyarShaharyar Member Posts: 54 Troubleshooter
    First I took backup of the binary inside the chip than re-record the binary again but the problem is still the same. Both U14(EC) and U34(Main) are re-recorded with the actually binary which were present before.
  • ShaharyarShaharyar Member Posts: 54 Troubleshooter
    Is it possible to extract EC from the main binary file ? Like I want to extract EC and main from the latest ZRQ.fd. Please guide. Thank you.
  • egydiocoelhoegydiocoelho ACE Posts: 79,933 Trailblazer
    I think you should google the EC bios file for your model. However, it is not allowed to post here in the community.

    I’m sorry about that. Before I googled it, there was not much information available for this specific model. But anyhow I’ll google more specific this time.
  • egydiocoelhoegydiocoelho ACE Posts: 79,933 Trailblazer
    One question: I know you've already extracted this file .fd:

    However, did you do this with version 2.30?

    From acer’s website
  • ShaharyarShaharyar Member Posts: 54 Troubleshooter
    And there are few order versions also available on the acer’s website of my laptop. Can I try recording every version on U34 ?

    You can try to retrieve the biography again, as published by colleague @JackE. However, try before disconnecting the battery, to restart the embedded controller and press the power for thirty seconds.
