Exactly what I said.....

Try pulling your head out of your ass , you're wrong and you just need to admit it . Oh , and I'm nobodies "cohort" , just relaying real life experience . Can you explain the motherboard that I installed in a different laptop - it had no CMOS power supply at all when it arrived . Worked just fine , the settings must have magically appeared outta my ass when I plugged it all up . -- Snag Is your membership in the ID-10-T club up-to-date?

You have Toms, but how about American Megatrends, (AMI) which is a major supplier of BIOS technology to the PC industry. They should know where the BIOS setup is actually stored today:
http://www.ami.com/support/faqs/
Historically, the BIOS and its settings were stored into CMOS (complementar y metal-oxide semiconductor) and was commonly referred to as the CMOS Setup . The CMOS and Real-Time Clock (RTC) required an electric charge to maintai n their settings. This was typically performed by an on-board battery. As t he battery aged, the electrical charge that maintained the CMOS settings di minished. The BIOS and RTC would then revert to its default settings, resul ting in, "Press F1 to enter the CMOS setup."
Note: The terms CMOS setup and BIOS setup were frequently used interchangea bly in the 1990s and far into the 2000s.
Beginning in the late 1990s, main board manufacturers started to store the BIOS into flash memory. There are two benefits for doing this.
*Flash memory does not require a charge to maintain its settings. *The size of the BIOS can be increased.
Note: Although the BIOS settings are stored in Flash memory, a battery is r equired to maintain the main board's RTC settings."
Pay close attention to that last sentence. It's *exactly* what I said. Now, to be sure, I can't say every MB implementation is done that way. Which is why I said "AFAIK". And to be fair, from Googling I saw other sources saying the setup is still stored in CMOS. A big part of the problem is that it's all referred to, based on past history, as CMOS setup, regardless of where it's actually stored.
Finally, we have the post Mr. Combs just made, where he says he has a Toshiba laptop with a dead battery and the only thing it ever lost was the clock. If the BIOS setup is in CMOS, how do you explain that?

Easy - the default values are sufficient for his level of operations.

I agree, that's one possibility. But if it's lost it's BIOS settings, you would think that when it boots it would come up with a warning message, telling you it's been lost, asking you if you want to continue to boot, etc. He's not seeing that.
The other possibility is that like AMI and other sources say, the BIOS settings in his PC are stored in Flash or other non-volatile memory. I don't see why all PC manufacturers would not be doing that. It's either free or tiny cost and it eliminates bad things happening due to a battery. You'd think just the relief from people calling their helplines, etc, it would be well worth it to build a better product.

Again your *logic* is flawed...what do manufacturers care about 5 to 7 yrs after purchase. They would want you to buy new, of course. Would they be willing to add a few cents to the design for that time to please a customer? Get real... Of course the designers push for these things...and eventually are incorporated into a build, much to their frustration. As always, you push your *talking points* to support your *thinking*...when often it is not the case.

Can you read? Who knows more about what manufacturers are doing? You or AMI that provides the actual BIOS software that does the setup storage?
As to why a manufacturer would care about what customers think about their product 6 or 7 years out, obviously you've never been involved in a real and successful business. You want customers happy, so they will buy their next PC from you. That's one very good reason. And when you can do that at zero, or close to zero cost, good businesses, particularly high tech ones, do it. But being a socialist loon, I'm sure you wouldn't know much about business.

It's not my thinking. I've given you several sources, including AMI, quoted above *again*. They say *exactly* what I said in my first post, that you disagreed with. And it's not just me here saying it, several other posters agree, including Mr. Coombs, who you promptly attacked for no reason.
Stop, just stop, instead of further discrediting yourself.

Yes, but often people are replacing a failing battery, indicated by something like not keeping accurate time. I didn't see any reason to assume the battery is completely dead.

was maintained by Vstandby, which was 5V coming from the power supply, when the computer was off, not the battery (Vbat). This enabled manufacturers to move from those big Tadiran batteries to the 2032 coin cells since the battery only had to power the CMOS when the computer was not connected to the mains.
The mistake some people made (and still make) is to disconnect the computer from the mains with a power strip after it is turned off. This forces the CMOS to be maintained by the battery.
So if the computer hasn't been unplugged, even if the CMOS battery is dead the settings are retained.
It's less of an issue now that the setting are stored in flash (other than the RTC).

Current battery dead. Computer doesn't know date, time, how much RAM it has, etc.

There's really nothing you have to worry about. Just avoid shorting anything on the board, and ground yourself before proceeding. You may have to adjust the BIOS afterward, but that can't be helped.
