Hello!
I recently bought an Acer Aspire C24-420 AIO PC. Everything works fine with it, except for a short beep sound after starting up. I suspect a checksum error. I found a program to update the BIOS among the drivers. The current BIOS version is R01-A3, and the new firmware is R01-A4. The description of the latter reads "Skip CMOS Checksum error message for CMOS Battery low problems".
My question is: Can I update the BIOS with the R01-A4 firmware from Windows 11, or should I try replacing the battery? If I open the case, will it void the warranty? Which solution do you recommend? Thanks in advance.

    NO!!! Nothing is wrong with your BIOS. The short beep is normal. Due to the risk of bricking the machine, do not try to update BIOS firmware unless you find a serious disabling problem that can't be fixed with normal driver or Windows updates.

    Hello!!

    @szaland57

    I understand that you would like to turn off the beep sound on startup of your All in One unit. The startup and shutdown sound alert may be disabled by 2 ways.

    Method 1:-

    1. Navigate to System > Advanced, Notifications tab.
    2. Check Disable the startup/shutdown beep.
    3. Click Save.

    Method 2:-

    1. Enter the BIOS (F10) and go to "Advanced" tab.
    2. Go to and select Boot Options.
    3. Scroll down and uncheck "Audio Alerts During Boot"
    4. Make sure you hit the "Save" button.
    5. Return to "Main" tab and choose "Save changes and Exit"

    Hope this helps you!!

    Windows 11 automatically overwrote the old BIOS. Everything is perfect. Thank you very mutch for your information.
