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.
