My thoughts exactly, which is why I never even considered it. I had a computer with a dead motherboard battery and the only thing it caused was that it never remembered bios settings. So I had to reconfigure them on each boot. And even then, it mainly only prevented OS boot if my HDD was configured to AHCI instead of legacy IDE. I don't know if these new issues are something to do with how the UEFI BIOS works or not, but I'd be interested to find out. But I'll definitely be taking note of this in the future when dealing with failing POST issues.It seems to be a lot more common these days that it actually fixes something. Not sure if that's 'cause they're using cheaparse batteries these day or if there's something about how the bios has to interact with hardware.
Used to be the biggest issue was that it would cause a motherboard to double boot every time because it wouldn't keep the memory profile.
I don't have one. I'm just going to grab another battery.Check the battery with a Greenlee power tedger?
