    what's your actual BIOS version?

     

    keep in mind this:

     

    How can i understand which version i need to download?


     Desktop versions:
    P01.xx can only be updated using P01.xx versions
    P11.xx can only be updated using P11.xx versions (normally P11.xx version are labeled "*not for upgrades")

    "L" BIOS versions are Linux OS dedicated (example P01.xxL)
     
    * what does it mean "not for upgrades"?
    During the windows 7 to 8 transition, some PC models had different BIOS versions from factory, related to the installed OS.
    Windows 8 PC got an UEFI BIOS
    Windows 7 PC got a "Legacy" BIOS

    So PC with Windows 7 installed from factory can't use the "not for upgrades" BIOS version, even if they were upgraded to Windows 8 or 10, since the factory BIOS was a different version compared to PC with Windows 8 from factory.

    Not yet, might try to do this today for the first time. Do you know the safest way to upgrade BIOS? Because I read online if you messed up you could brick the whole motherboard.

    You should contact acer support directly and verify if you can update to p21-a4so --- which is for M4620G in the meltdown/spectre page. As this is a security patch that can only be done via bios, you can escalate your call until you can find a live person who can verify it.

    I am 90% certain that you can apply the update as M4620 and M4620G share the same bios.

    I find it easiest to update from Windows. Extract the archive and read the docs... IIRC you open the WIN folder and execute a batch file.

    Yeah, I also didn't thought upgrading the bios that fast and easy lol, literally takes only 2 minutes with restarting and boom its done.
  • billseybillsey ACE Posts: 11,581 Trailblazer
    Yeah, when everything works as it should it's easy... It's when something doesn't work right that we typically end up spending a lot of time to fix. :)
