Can someone please instruct me on how to correctly update the BIOS on my model? I downloaded the files thru Acer, but there are multiple folders of different installation types (EFI, ROM, UCP), and I'm unsure which I need and the correct steps.

Thank you.

    To update the BIOS on a TC-885 you extract the ZIP to a folder on your machine, then go into the WIN folder, then double click on either the FLASH.bat or FLASH_X64.bat file. In pretty much all cases you should be using the _X64 version, you would only use the other if you had for some reason replaced the normal OS with a 32bit version.

    Firstly, why do you want to update the BIOS? As updating a BIOS is a very risky thing and as Acer warns you on their site and on the BIOS file update page that "Upgrading your system BIOS incorrectly could harm your Acer product. Please proceed with caution" be warned and do this at your own risk, I take no responsibility!

    If you have taken note of the above then proceed as follows: download and unpack the .RAR the latest BIOS for the TC-885 "Enhance system performance" version R01-C2 dated 2020/03/24 file from here: https://www.acer.com/ac/en/AU/content/support-product/7624?b=1  seeing that you have a UEFI BIOS you have to use the EFI method and follow the exact steps as instructed in this Acer guide "ME FW & System BIOS Update SOP for EFI Shell v3.08" PDF instructions (see this PDF attachment below) be warned as and if you don't follow exact instructions then you could brick your system! This will update the BIOS of your Aspire TC-885-UA91 to the latest "Enhance system performance" version R01-C2 dated 2020/03/24.

    For UEFI BIOS's it’s essential to not install your BIOS within the normal OS environment. You will need to unzip and move your files from your BIOS folder into the root (outermost) directory of a storage device, like a flash drive. Once you’ve saved your files to your USB drive’s root folder, plug it into your computer and restart the PC. Afterward, enter your BIOS and locate the flash option and follow the above steps.


    Side Note: 
    Most PC users go without ever updating their BIOS. After all, PC performance is often unaffected by your BIOS version. So why would you? Two words: continued stability. An outdated BIOS may limit PC performance, lower PC stability, debilitate overclock settings, and remain incompatible with certain devices. When confronted with issues, most PC users will try everything in the book without realizing their issues stem from an outdated BIOS. The general recommendation is: you’re fine, until you start noticing hardware compatibility issues. A UEFI (United Extensible Firmware Interface) BIOS is the more modern form of the BIOS. UEFI BIOS shares many similar features with old-school — often called legacy — BIOS versions. The biggest innovation in the UEFI BIOS is its clickable and more accessible user interface (UI). The UEFI BIOS also allow for great added features like hardware monitoring, more convenient overclocking accessibility, overclock profiles, and easier flashing capabilities. Also, the advent of UEFI BIOS versions gave way to massive (> 2.2 TB) storage systems which wouldn’t function on the legacy BIOS. It also allows for pre-boot environments which can be used when needed to move files, diagnose issues, and even browse the internet without the need of an operating system (OS).

    Since the Aspire TC-885-UA91 is a rather new computer, what makes you to think about updating the BIOS? Are you experiencing hardware problems? I have this computer and things are all O.K.. Just don't know is it worthy to do the update!

    Hi -- The reason is the function keys on this model's keyboard. In order to use them, you have to press Fn each time, which is a problem for my specific application use (wastes time). Otherwise, the function keys operate as other functions (brightness, sleep, mail, etc). I'm hoping a BIOS update will have options to change this. Or, I'm wondering if I replace the keyboard it might solve the problem.

    Hi Steven D,

    I got a defective Acer keyboard. The F12 key just did not work, so I was not able to reach the boot menu when boot up. Then I changed to a generic keyboard, which allowed me to reach the boot menu now. Since it is easy to swap the keyboard with the USB connection, I think it will be good to swap back to the Acer keyboard when I do not need to reach the boot menu, and I can use the functions of the other function keys.

    Would you be kind enough to tell me the functions of the 12 function keys (both with or without the Fn key pressed)? No info were found from the Acer web site regarding the function keys.

    Thanks!

    Because the keyboard layout is different for each different locale, what the keys do can change from one place to another. What is displayed on your F12 key? Mine says F12 and NumLk.

    Without Fn pressed, by default the buttons do: F1 (notification sidebar), F2 (sleep), F3 (outlook), F4 (Scr Lk), F5 (page refresh), F6 (favorite), F7 (taskbar search), F8 (screen dim), F9 (screen brighter), F10 (music prev track), F11 (play/pause), F12 (music next track). Fn pressed depends on what functions you set for your specific app use.

    Since you have a generic keyboard, does pressing the Fn keys do any of the functions above?

    Dear Steven D,

          Another fellow user answered my question about the 12 function keys with the assumption of pressing the Fn key down. The functions seemed to be the same as the functions that you mentioned without the Fn pressed.
          
        I tried the functions with the generic keyboard (that I am using now). That seemed to work even without the Acer keyboard. Some keys like F2 (Sleep), F3 (E-mail) will not work because I did not enable sleep mode, and did not set up Outlook. My generic keyboard just does not have the Fn key at all.

     Thanks again for your time!

    Oh, Billsey, thank you for answering my question too, if you see this!

    You should ALWAYS update BIOS because it is the ONLY way to patch certain security vulnerabilities like meltdown, spectre and all the other Intel CPU security vulnerabilities. Intel just came out with a new bunch of security vulnerabilities THIS WEEK that requires microcode updates.

    @Joe9844 although that's a good reason to update a BIOS, it only make sense if those are what the update addresses. If the update is for something completely different then you are just doing a risky procedure for no real gain.

    Except that 99% of the time, Acer doesn't tell you any useful information about what the bios update is updating. Normal people who aren't trained IT specialists will never understand that this particular bios or that particular bios is for microcode update for such and such Intel CPU vulnerability.

    Acer doesn't even bother to post anything useful after their initial meltdown/spectre page. We know that there are half a dozen of newer CPU vulnerabilities after meltdown and spectre that require microcode/bios update.

    You basically have to ASSUME every single bios update is about security vulnerabilities.

    In the last 30 years, I have done countless bios updates, 56K telephone modem firmware updates, printer firmware updates, dvd burner firmware updates, digital SLR firmware updates, handheld GPS firmware updates, my car's satnav firmware updates and my big screen tv firmware updates. As long as you double-checked that you have downloaded the correct firmware for the correct hardware model and you don't update them during a thunderstorm, there should be no problem.

    I followed all the steps, but I'm having trouble with accessing the "EFI Shell" in order to flash the update. How can I boot into EFI Shell? There are no options in BIOS for that. Are you sure I should use the EFI method? What about the other methods -- and what do they stand for anyway: such as the "UCP BIOS Update" method?

    THANK YOU! Yours was the only concise answer. It worked. A question: Should the instructions to copy and run the update off USB be ignored?

    Yeah, pretty much. Although any BIOS update is risky, any failure while in the writing process pretty much bricks the MB, it's not inherently less risky to be running from a USB drive than from the HDD or SSD.

    StevenD, I have the same problem with the stupid Acer keyboard.  There is no way to get it to default to using the F1, F2, F3, etc. function keys.  Instead it defaults to the "special" action keys that I never use.  I tried updating the BIOS to the latest R01-C3, and there is still no option to disable the action keys.  The only solution I have found for this is to throw the Acer keyboard in the garbage and replace it with a generic keyboard that has regular function keys.

    As for updating the BIOS, I have updated many BIOS's on many computers, and I have never had a problem.  Just make sure your power is stable.  I am not sure why some people are so scared to update the BIOS.  To update the Acer BIOS, I unzipped the BIOS file, went into the UCP folder, and ran the "RO1-C3.exe" file.  Windows may not like the file, so you may need to click something like "more" or "options" to allow the file to run.  It looked like 3 files were updated, and then the computer booted 3-4 times before finally booting up to Windows.
