OT Hints on replacing computer CMOS battery?

If you had changed any bios settings from default they would also have been lost, ut on Tosh laptops the factory installed ramand drive specs were urned into the bios as default, so there was very little to customize.

Why doesn't everbody plonk the trader - then I wouldn't have to catch his drivel second and third hand.

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?

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

This one's 14 years old, Needs CMOS for date, time, RAM size, etc. Battery is dead.

Why don't you go plonk yourself? As dumb as you are, with as many totally wrong posts, especially on electrical code issues, I still haven't "plonked" you and would never call for anyone else to do so. By ignoring people, you're just living in your own little world, which leads to, well, being dumb.

And note, instead of the ad hominem attack, why not just address the issuem where I was correct and what I posted to support it?

AMI:

"Note: Although the BIOS settings are stored in Flash memory, a battery is required to maintain the main board's RTC settings."

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.

Precisely...just where your thought process originates. (and your ability to punctuate properly!)

Oh , Fuck you . I do it because it drives anal-retentive dickheads like you nuts . Though in your case that's more like a putt ... -- Snag Doood , you are just plain wrong about the need for a CMOS for anything other than the RTC .

Usually not the case. Starting with ATX power supplies, the CMOS memory 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).

Exactly, and even the RTC doesn't matter (to me anyway) since the OS retrieves the time and resets the RTC immediately after system boot.

...and, if put the PC in sleep mode (even with a dead Cmos battery) no ill will come of it!

Correct.

Some will never learn.... Once again, from AMI, a leading supplier of BIOSs to the PC industry:

"Note: Although the BIOS settings are stored in Flash memory, a battery is required to maintain the main board's RTC settings."

Completely consistent with what Mr. Coombs is reporting happens with his computer.

Or From Wikipedia:

"Nonvolatile BIOS memory refers to a small memory on PC motherboards that i s used to store BIOS settings. It was traditionally called CMOS RAM because it used a volatile, low-power complementary metal-oxide-semiconductor (CMO S) SRAM (such as the Motorola MC146818 or similar) powered by a small batte ry when system power was off (called the CMOS battery).

The term remains in wide use but it has grown into a misnomer: nonvolatile storage in contemporary computers is often in EEPROM or flash memory (like the BIOS code itself); the remaining usage for the battery is then to keep the real-time clock (RTC) going."

Just the facts Clare and note that I'm not calling on anyone to plonk, or censor you.

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.

Mr. combs, mr. comes, mr. combs, come to my rescue! Manufactures care about as much as a conservative (or liberal) after they're elected! And you live in the *real* world...I thought only liberals were *pie-in-the-sky* idealists?

It's Coombs , that is : C double 0h em bee-ess , with the emphasis on Bee Ess . I don't know why you're looking to me for validation , I think you're just another idiot troll . With low self-esteem and poor reading comprehension . And bad breath too ... Oh , and the only thing the CMOS battery powers in any of the 5 computers I have set up and running here is the RTC . Examples include an e-machine , a HP , a Tosh laptop , and 2 homebuilts running Asus M2A-VM mobo's with AMD Athlon X2 processors .
