    Good evening WOLVERINEISMAD2020 !

    Why did you update Bios?
    Bios updates are extremely delicate and risky processes and should only be performed in serious cases of serious system errors or due to extreme need for correction or compatibility.
    Otherwise, it must be avoided.

    Downgrade can simply render your device unusable, in addition to the need for flash bases.

    Access your Bios and press F9 then F10 to restore defaults.

    Then perform the battery reset and do a test.

    i've restored the bios to default and did the battery reset and the same problem still exists. Maybe Acer should test their bios systems first before they deploy them to the web. I have bios version 2.03. Update ME-FW 11.8.65.3590. 2.Update MCU

    Acer tests and alerts all users of possible BIOS update badges.

    In that case, I recommend that you contact support Acer if your region.

    I disagree with @MaClane in this topic. BIOS upgrades are not as dangerous as they're paint them to be, not in this day and age.

    There are plenty of safeguards in place: signed firmware blobs, requirements to have a battery and at least at 25% of charge as well as an adapter plugged in, more validation even during the real flasher after the machine reboots (i.e. something's off and it won't flash), ...

    Looking at the changelogs for that particular machine I see they have been upgrading not only the microcode of the processors themselves, but also video BIOS and ME firmware, so those BIOS upgrades also carry security fixes unlike those of the A515-54G which to this date none even touch the ME code or MCU.

    Downgrading to an earlier BIOS is easy as well, you just have to modify the specifications for the high-level Windows programmer (that does some checks and copies the ROM file for the real programmer to do the job) to allow you to use lower versioned flashes.

    Because of the specifications for that particular model state that the BIOS is to be flashed completely (everything gets erased and reprogramed with the newer or older code) I can't see why it would be risky to go back to an older revision either. Contacting Acer isn't likely to get you anywhere, or have you sent the laptop for servicing, which may just as well come back with the latest firmware release (it wouldn't be the first time, nor the last I'm afraid).

    Is it the safest option, to contact Acer and inquire about the procedure or what to do to revert back to an older release? Absolutely, besides they can reprogram the SPI chip directly bypassing any kind of security measures the upgrader has to go through.

    Is it possible to do with the current upgrader? Yep, perfectly possible, without breaking ACUA either because you're flashing officially released materials and not circumventing any security features. A version check is not a security feature, it's a sanity check at best. Modifying the firmware and trying to get that flashed is, but as I said it'd break signatures and the upgrader wouldn't do it.

    So if you get unsatisfactory replies from Acer Canada, and wish to try it on your own, let me know the revision you want and I'll just change the configuration so it can be flashed back.

    The fact is that the Bios' firmware may suffer incompatibilities with the versions of the controllers.
    Only in the Acer forums, even following all the update protocols, I receive more than 50 users with problems due to updates every week.
    Several publications by renowned experts in the field affirm and assure the same position as mine:

    Bios updates are extremely delicate and risky processes and should only be performed in serious cases of serious system errors or due to extreme need for correction or compatibility.
    Otherwise, it must be avoided.

    To each their own, I just stated my stance on the matter, I wasn't looking for approval of backing from anyone either ;)

    Either way, if a firmware update fails following every directive given by the manufacturer, the problem isn't related to the process itself but the quality control they have, Acer in this case, being sub-par to say the least.

    Firmware can be changed by operating systems, as in the case of the latest Windows patches, which force these updates.
    So if there is any incompatibility between a Bios update provided by Acer and such firmware updates forced by Microsft, it has absolutely nothing to do with Acer quality control.
    It is not a matter of "approval" but of information that everyone should be aware of.

    Oh but it does, it is the manufacturers who write the code, not Microsoft, unless for their own Surface line of products. Manufacturers just publish through Windows Update is all, that's the delivery method, nothing more.

    But seriously, I've tinkered and flashed firmware in almost any imaginable way, bypassing protections, signatures and what not. Messed around, broken things, sometimes even bricked things; but that's what you get when you go reverse engineering.

    Still, how things are nowadays, if manufacturer X supplies a firmware upgrade and it is flashed through their approved method with all of the checks and tests that are in place and there are problems afterwards, there's noone to blame but the manufacturer. Whomever came up with the BIOS package didn't test it properly in pre-production before releasing it to the public, just like any other piece of code, accountability is all.

    Avoiding to install a firmware update that tackles security vulnerabilities is equivalent in my opinion to avoiding updating Windows because "it works fine just as it is and I see no viruses or anything", poor security practice, but then again, just an opinion.

    We'll just have to agree to disagree.

    So was my initial comment, information people should be aware of.

    Agreeing or disagreeing does not prevent or eliminate facts.
    I just quoted and stressed the facts.
    And I stressed only those that occur in the Acer forums.
    I did not raise the other hundreds that occur in the forums of Dell, Asus, Lenovo and Samsung of which I participate and contribute.
    So I stick to the facts and events.
    It is not a matter of opinion.

    Are you implying I did otherwise?

    Fact, platform.ini, the configuration file for Insyde's H2OFFT explains it all in great detail.

    True as well.

    You can keep on writing about the matter if you want to, but I'm out, I made my points and stated my stance on the whole affair. Opinion wise you clearly differ from me on whether it's good to upgrade the firmware of machines, or SSDs, or whatever that implies re-programmming a ROM chip by extension because of risks; and it's good that there are diversity of opinions, but I will not engage in a dialogue that seems pointless and going nowhere.

    So this is my last post on the matter.

    I am not suggesting anything at all.

    I just expounded my opinion based on facts, aimed at novice users and that most of the time they don't have basic and adequate knowledge to solve questions of this level.

    So I believe that we must focus and evaluate each case according to the level of knowledge of each user.

    After all, there is no point in raising a flag focused on technical details and not solving users' doubts.

    if its slow after a bios upgrade you might have to reset you boot options so your first device is the windows HD not the CD rom or other HD or USB drvice.
